A hot tub is a large tub filled with water and used for therapy or relaxation. It can be a great investment for a homeowner. They may be associated with health benefits like improving sleep, cardiovascular health, diabetes and weight loss, and eliminating tension and stress. They can also be used to entertain guests or relax in the oasis of your home.
The average cost for a hot tub installation project is approximately $4,000 to $8,500, with the average customer paying $6,900 for an outdoor prefabricated wooden hot tub fitting four to six people. This includes installation labor fees and the work of an electrician. The lowest cost option is an outdoor inflated hot tub for two people at $1,000. The highest cost option is an outdoor custom stainless steel hot tub with a cover lifter for 12 people at $20,000.

When installing a hot tub on your property, the first choice you will have to make is if you want a prefabricated unit that is already designed and ready for installation or if you want to create a custom build made specifically for your space. Both options offer unique pros and cons, so your decision will most likely be based on your budget and your wants and needs. Depending on which type you choose, you can expect to pay from $4,000 up to $20,000. Let’s take a closer look at both below.
|Type||Cost Range (Installed)|
|Prefabricated||$4,000 - $8,500|
|Custom||$5,000 - $20,000|
On average, prefabricated models cost between $4,000 and $8,500. As the name suggests, prefabricated units are already built, so you don’t have to make any additional decisions about how it looks. All you have to do is figure out which type best suits your space. There are plenty of options you can choose from for prefab units so that you won’t be left with an uninspired look. Prefab units can be above-ground or in-ground and can be placed inside or outdoors, which still gives you a lot of freedom. These are built in advance to meet the average homeowner’s wants and needs. If you have more specific needs or wants, you may prefer a custom option.
You can have a unit built to your specific needs and ideas. This includes shape, jet positioning, installation location, and sometimes materials. Custom-made units cost between $5,000 and $20,000, depending on the size and material. They can be made of wood or molded material and installed indoors, outside, or in-ground. They are normally built-in or placed in the ground rather than portable. They have a lead time of several weeks to build, so plan accordingly.
Often, people think of hot tubs as only being located outside, but there is always the option of installing an indoor model. This change in location impacts the overall cost of your installation project. Both indoor and outdoor units come with their own unique advantages. The right choice for you depends on the amount of space, the climate you live in, and your other personal wants and needs. For the sake of the rest of this guide, we will focus on outdoor installations. However, it is still important to consider the costs of indoor installations. The price of installation ranges from $4,000 up to $25,000 depending on the unit being installed outdoor or indoor.
|Location||Cost Range (Installed)|
|Outdoor||$4,000 - $20,000|
|Indoor||$5,000 - $25,000|
Typically, the cost to install an outdoor design ranges from $4,000 to $20,000, depending on its size, shape, and location. They are often installed outside out of convenience and due to the greater amount of space available. They are easier to install and maintain. For these reasons, outdoor installations are less expensive than indoor alternatives. Outdoor units automatically have proper ventilation and natural drainage. Plus, they give you the chance to enjoy your surroundings from a comfortable spot. However, they offer less privacy than indoor units.
With the proper ventilation requirements and foundation, an indoor option costs more than one outdoors. They typically range between $5,000 to $25,000, depending upon materials, location, heating, and other requirements. Indoor units can be of any type and provide advantages, such as privacy, safety, and climate control. There are requirements to consider before installing them.
First, installing an indoor unit in a room with proper ventilation is important to prevent condensation, including fans and a dehumidifier. Walls and doors should have a water-resistant covering to avoid damage. Next, using the correct foundation is extremely important. They are very heavy. Once filled with water, they can weigh a ton and apply high pressure to the surface they are on. Therefore, they should only be placed on a concrete slab. The flooring around it should be anti-slip and provide good drainage for all the water that inevitably spills out.
Generally speaking, there are two types of units that you can install at your home: above-ground and in-ground. Both types come with their own unique advantages and drawbacks, which is why it’s important to fully understand what you’re getting into before you decide which type you want. The cost of above-ground and in-ground tubs ranges in cost from $1,000 up to $20,000. We’re going to dive into deeper detail about both types so that you can make the most informed decision for your home.
|Type||Cost Range (Installed)|
|Above-Ground||$1,000 - $15,000|
|In-Ground||$15,000 - $20,000|
Above-ground units range from $1,000 up to $15,000 on average, including installation. Above-ground units are also often referred to as portable and are usually prefabricated. Some non-portable designs can be considered above ground because they are above ground level, but these are usually built-in. These are more expensive than portable models ($7,000 to $15,000) due to labor costs but less expensive than in-ground ones since the former does not require excavation. Any unit that is not built-in or anchored in some way to your home, deck, pool, or the ground and can be drained, unhooked, and moved is considered portable. This includes inflatable, soft-sided, molded, and even wooden units not built into a deck. Portable units are popular due to their lower costs ($1,000 - $8,500) and simple installation. They can usually be plugged into a 240v outlet and moved around if needed. They are easy to maintain since there is easy access to all the mechanics, which are well-protected from the elements. However, there are not as many options for interior materials. These can be difficult to get into and out of, especially for those who are older or living with mobility issues.
|Above-Ground Types||Cost Range (Installed)|
|Portable||$1,000 - $8,500|
|Built-In||$7,000 - $15,000|
This option can be a major investment that requires professional installation. They are expensive, ranging from $15,000 to $20,000, due to the high installation costs of plumbing, electrical work, gas hookups, and excavation. These units add a dramatic effect to your landscape when they are built into the deck or patio for easy access or within a backyard landscape. They can take weeks to build and offer fewer features and lower energy efficiency than above-ground options. They are most commonly made of acrylic or rotomold because these materials are not affected by the soil they are installed in and do not rot like wood.
While material plays a role in the prices, size is arguably the most important factor. Quite simply, bigger models have more material and labor costs. The size you install should be determined by how many people you want to accommodate. For example, if you have a family of six, make sure your unit accommodates a minimum of six people. If you entertain frequently, you may also want to size up so that guests can use it. Keep in mind that occupancy means the number of people who it is designed to hold. While you may cram more people in, this may not be comfortable, safe, or advisable. In fact, it can damage your tub and the area surrounding it. Here are some common sizes for prefabricated models and their associated costs, ranging from $1,800 up to $20,000.
|Occupancy||Prefab Cost Range (Installed)||Custom Cost Range (Installed)|
|2 People||$1,800 - $6,000||$3,300 - $10,500|
|3 People||$2,300 - $7,000||$3,800 - $12,000|
|4 People||$3,300 - $8,000||$4,800 - $13,000|
|5 People||$3,800 - $10,000||$5,300 - $13,500|
|6 People||$4,800 - $11,000||$5,800 - $14,800|
|7 People||$5,800 - $11,500||$6,800 - $15,500|
|8 People||$6,800 - $12,000||$7,800 - $15,800|
|9 People||$7,800 - $13,000||$8,800 - $16,000|
|10 People||$8,300 - $13,500||$9,800 - $16,500|
|12 People||$8,800 - $14,500||$10,800 - $20,000|
Two-person designs are among the smallest and most economical options you can find. This size costs $1,800to $6,000 for prefab units and $3,300 and $10,500 for custom builds, depending on the material and where you install it. On average, they are about 5’4” long, 5’4” wide, and 29” high. They come in a range of materials and shapes, with rectangular and triangular being the most common because they allow users to stretch and relax. Circular is another popular design for these compact options.
You are not going to find many of these options, but they exist. They range from $2,300 to $7,000for prefab units and $3,800 and $12,000 for custom builds. Sizes of three-person models vary but can be between 6’0” and 6’5” long, 6’0” wide, and 29” to 35” high. Most of them are made for an even number of people, but some are designed to have one person seated in the center of one side, while two people can occupy the ends of the opposite side, managing to have three people in one unit.
Four-person models are a very common option for the average home. Expect costs to fall between $3,300 and $8,000 for prefab units and $4,800 and $13,000 for custom builds, depending on the features you select. These are generally 6’2” to 7’0” long, 6’8” to 7' wide, and 35” tall. While they are larger, their costs are not much higher. This model offers the most options for features, materials, and shapes. The only shape you really can’t have for a four-person unit is a triangle unless you work with a designer on a custom build.
These ones are rare and difficult to find, although they do exist. Expect costs between $3,800 and $10,000 for prefab units and $5,300 and $13,500 for custom builds. These range in size and are generally 6’6” to 7’0” long, 6’4” to 7'0” wide, and 33” tall. The interior configuration is designed to have people seated across from one another, moving every other person to one side. They are usually rectangular because this best accommodates the interior layout.
Six-person designs are also common and popular. They typically cost between $4,800 and $11,000 for prefab units and $5,800 and $14,800 for custom builds, depending on the features you choose. Six-person models are generally about 6’6” to 7’9” long, 6’4” to 7'9” wide, and 33” to 38.5” tall. These are good for families of four that entertain and couples who host guests regularly. They offer space to spread out and many different features.
Seven-person units are also rare, like three- and five-person ones. These cost between $5,800 and $11,500 for prefab units and $6,800 and $15,500 for custom builds on average. They are in the size range of 7’ long x 7’ wide x 36” tall. Those that exist are rectangular and limited in options. If you have specific needs for a seven-person unit, you may be better off having one built or opting for an eight-person unit, which is easier to find.
These are not as common as six-person models. They come in various materials and have a wide range of features. They cost between $6,800 and $12,000 for prefab units, and $7,800 and $15,800 for custom builds. These are usually in the range of 7’6” long x 8’ wide x 37” tall. If you have a big family or entertain frequently, this is the model for you. They are a good choice for smaller families where people may want more room to spread out.
As with the other odd-numbered designs, these ones are not common. However, they do exist. These units generally cost between $7,800 and $13,000 for prefab units and $8,800 and $16,000 for custom builds. This unit is 8’ long x 8” wide x 37” tall. Overall prices vary depending on the make and model you choose and additional features and accessories. Pricing does not vary much between these models and alternative units for eight or ten people. Unless you specifically need a nine-person unit, you may go for one of those two options.
If you consider getting a ten-person unit, you can expect to pay between $8,300 and $13,500 for prefab units and $9,800 and $16,500 for custom builds. These are highly customizable and come in a wide range of shapes and materials. They also have custom sizes, which are 8’6” long x 8’6” wide x 38” tall. If you have a large family, a unit this size will be a beneficial addition. It can also be a great place to relax for any guests when you’re hosting larger events.
A twelve-person unit costs between $8,800 and $14,500 for prefab units and $10,800 and $20,000 for custom builds. This is generally the maximum number of people you can fit into a residential unit. Therefore, these prefabricated and custom units are the most expensive. They cost more to heat, too. Whether you have a big family or you often host parties, this size will be a great addition to your home. This unit measures 9’ long x 9’2” wide x 38” tall.
Hot tubs can have various shells, which is the interior material used to make the unit. Although you may not notice at first glance, the type of shell material used impacts the look, feel, and overall costs. Some materials can be used for any type of unit, while others are specific to in-ground or above-ground units. Additionally, some materials are not able to be used in custom builds versus prefabricated ones. Here are some of the most common materials used for different units, ranging in price from $2,000 up to $20,000.
|Material||Prefab Cost Range (Installed)||Custom Cost Range (Installed)|
|Vinyl||$2,000 - $5,000||N/A|
|Roto-Molded (Polyurethane)||$2,500 - $6,000||N/A|
|Fiberglass||$3,000 - $10,000||N/A|
|Wood||$3,500 - $8,000||$5,000 - $11,000|
|Acrylic||$4,500 - $9,000||$8,000 - $16,000|
|Cement||$5,000 - $11,000||$8,000 - $17,500|
|Stainless Steel||$6,000 - $12,000||$10,000 - $20,000|
Vinyl 1 is most often used in soft-sided or inflatable units as a liner over a different material. Typically, it costs between $2,000 and $5,000 and is mostly used in prefabricated units. Vinyl shells are the least expensive option on the market. However, that means it cannot withstand as much wear and tear. In addition to being prone to cracks and tears, it is more likely to fade over time from UV ray exposure and chemicals. Vinyl is the least efficient material when it comes to heat retention. So, what you get to enjoy in low upfront costs you may have to make up for with frequent maintenance. These can be both above-ground and in-ground, which makes it a flexible option overall.
Rotationally molded or rotomold models are made from polyethylene 2 (HDPE) material, similar to the material used in kayaks and refillable water bottles. These range in price from $2,500 to $6,000. They often appear duller and lack the sparkling appearance that acrylic shells offer. The way the material is created yields an almost matte finish. It is a step up from vinyl in terms of performance and is more cost-effective than acrylic shells. Rotomold units come in one piece and do not offer the ability to customize the tub with cabinets, shelves, jet upgrades, or TV options. These offer fewer color options and are typically only available as prefabricated above-ground models.
The average above-ground and in-ground fiberglass 3 unit cost ranges from $3,000 to $10,000. Fiberglass is a quality material that is more cost-effective than acrylic. However, it does not offer as many style choices involving textures, colors, and additional fixtures. For this reason, it is often used only for prefab units. Additionally, it is not as durable as acrylic. With that being said, fiberglass is still extremely low-maintenance, so you don’t have to worry about any complicated cleaning regimens. Fiberglass is very lightweight, making it a great choice for above-ground and in-ground models.
Wooden units range from $3,500 to $11,000, depending on the size, accessories, power type, and wood. Prefab units range in cost from $3,500 to $8,000. Custom builds range from $5,000 to $11,000 on average. They can be electric-powered, gas-powered, or wood-fired. They sit above the ground and offer bench seating. Generally, these are much deeper than acrylic or rotomold units and offer a few jets, lights, and controls. Some popular materials include redwood 4, cedar, cypress, oak, and teak. Electric and gas-powered models are the most popular of the three and are more expensive yet easier to operate. Wooden tub shells offer a beautiful natural look, but they can’t be molded into smooth benches. They also can’t hold heat as well as plastic alternatives. You may have to deal with higher energy bills, too. To top it off, wooden models require more complicated fixes for maintenance and upkeep.
On average, acrylic hot tub shells cost between $4,500 and $16,000. The cost of prefabricated units ranges from $4,500 to $9,000, while custom units cost between $8,000 and $16,000. Acrylic is one of the most durable options on the market. However, it is much heavier and often more expensive. Acrylic shells can either be backed or unbacked. If it is backed, it will have an extra layer of polymer ABS on the underside and can be used in deeper tubs. Unbacked shells can often have a layer of fiberglass on the underside, which will provide protection but not as much heat retention. Acrylic can be used for both in-ground and above-ground units.
Concrete hot tub shells are less common than other materials. On average, they cost between $5,000 and $17,500, with prefab units ranging from $5,000 to $11,000 and custom builds ranging from $8,000 to $17,500. Concrete models are best designed to be in-ground because they will naturally shift and settle over time if not securely placed in the ground. Additionally, they are very heavy. Though they are more expensive, these units last up to ten times longer than an acrylic alternative with just a bit more maintenance.
Stainless steel hot tub shells are another uncommon choice, but they exist. They range in cost from $6,000 to $20,000. Steel can be used for both prefabricated and custom builds. Prefab units generally cost between $6,000 and $12,000 while custom units range from $10,000 to $20,000. Generally, they have a higher initial cost because stainless steel has a very long life expectancy. Stainless steel models require less maintenance than other materials and are much lighter, so they are often used for above-ground applications.
There are not many installation costs if you purchase a ready-made unit. Most are designed to sit on a patio or concrete pad 5 and are designed for the homeowner to set up.
Inflatable tubs can be put up by the homeowner, while plug-and-play unit with electric heaters can be delivered, filled, plugged in, and used. Custom, built-in, in-ground, and other specialty tubs have other associated costs. Most pool professionals install the unit and handle all associated work, except for wiring and running a gas line.
Labor costs depend on whether you choose prefabricated or custom-made. If you decide to buy a prefabricated one, the delivery and transport cost around $250 to $400, depending on how many professionals are needed and the amount of work. Difficult accessibility increases costs, with a $200 additional cost if a crane is required.
If you need a foundation for your prefab unit, expect installation costs for this of around $1,600. Filling the tub is generally done by the homeowner. All you need is a hose. If you have a professional set it up, meaning it is unboxed, moved, located, and all the working parts tested and assembled on-site, expect to spend $200 to $800 in labor costs.
For a custom option, you may have other installation costs, but these are usually factored into the tub’s cost since it is being quoted and built specifically for your home. For example, the average custom model built to fit four people ranges in price from $5,000 to $10,000, with about $2,000 to $5,000 being used specifically for labor expenses.
Once the hot tub is set in place, an electrician may need to help with the electrical set up. If there is no outlet around, then an electrician has to install an electrical outlet nearby. An electrician has to set up the wiring into a control pack and install a GFCI next to the hot tub at least 5 feet away. This job averages between $120 and $200. Costs increase by about $70 if you want to bury the electrical components. On average, electricians charge between $40 and $120 per hour for most jobs. This process will take about three hours. If an electrician needs to complete this work, it is important to check if a permit is required in your town or city.
Once all the electrical work is complete, you can start to fill your unit with water. It is important to add the proper chemicals after filling. Complete instructions should be stated in the owner’s guide. Then, you can adjust your settings and heat it.
An in-ground unit is expensive to install. The process is longer, with days of excavation, shell installation, and finishing work. It involves excavation, during which a hole is dug in the ground, and the soil is removed. This job takes a day or two, depending on how big the hole is and how smoothly the process goes. This process is usually done by people from the company. Following the excavation is the shell installation, which lowers the shell into the ground and finishes it off with the necessary cement and gravel to build the foundation around the shell. The ground around the tub is improved by installing either stone, tile, or brick for a beautiful finish. Some people may also decide to use coping to finish off the perimeter. Depending on the job’s extent, the installation takes anywhere from a few days to several weeks.
This process has higher installation costs than standard, above-ground designs. These include the cost of excavation ($2,000), delivering and lowering the unit into the site ($200 to $500), set up of the model and its features ($500), running the pipe and electrical wiring below ground to the site ($1,800 to $2,000), and the wiring ($400 to $500). This makes the total installation costs for an in-ground unit around $4,900 to $5,500, along with the tub’s cost ($15,000 to $20,000).
Replacing your hot tub is a complex project, which is why it is important to have a contracting team on your side from start to finish. First, they remove your existing unit, which involves disconnecting the power source, emptying, and removing it. The average removal cost ranges from $250 to $400, depending on its size, location, and any other complexities involved in the removal. Depending on the size and shape of your old unit versus the new one, you may need to plan for additional construction of the surrounding area. This can be especially true if your unit was placed inside your deck instead of simply sitting on top of it. From there, you will just have to pay for the new unit, which generally costs between $4,000 and $8,500.
Hot tubs come in several shapes, including custom builds. While the shape is not a big driving factor behind the cost, the shape affects size, occupancy, and even where it can be installed. Since all these things impact the cost, it is important to keep the shape in mind when planning your installation. Below, we will talk about some of the most common shapes for prefabricated units (circular, triangular, rectangular, square) and custom builds, too. That way, you can get a better idea for your project. Depending on which one you choose, you can expect to pay from $1,000 up to $20,000.
|Shape||Cost Range (Installed)|
|Circular||$1,000 - $5,000|
|Triangular||$2,000 - $7,000|
|Rectangular||$3,000 - $8,000|
|Square||$4,000 - $10,000|
|Custom Shape||$5,000 - $20,000|
Circular designs are generally among the least expensive, ranging from $1,000 to $5,000. They are smaller and usually not as deep as other models. They also usually fit fewer people, with most being made for two to three people comfortably. Some very oversized models fit up to four people. Circular units can be inflatable, soft-side, wood, or molded and can be installed nearly anywhere.
Triangular units are a good choice if you are short on space because they easily fit into corners. These are generally a bit more expensive than circular ones, even though they often fit the same amount of people, ranging from $2,000 to $7,000. They have an odd shape and are often installed in tighter spaces. They are generally small, molded units made for one or two people. It is difficult to find them in other materials or sizes.
Rectangular units are a good choice if you want more legroom in smaller, lower occupancy tubs. They cost between $3,000 and $8,000 on average. A two-person rectangular unit lets people stretch out more comfortably. A larger rectangular option holds more people, although not as many as a square one. Rectangular models come in molded and wood forms and some smaller inflatable units.
If you want to maximize occupancy while having enough legroom for everyone inside, consider installing a square unit. They can be installed anywhere and cost between $4,000 and $20,000. These come in various materials and a wide range of sizes and fit between 4 and 12 people. These can have more modern features such as lights, waterfalls, fountains, and powerful jets, offering therapeutic benefits.
If you want a very specific unit for your space, consider building your own custom unit. On average, these cost between $5,000 and $20,000. Custom units can include all the shapes listed above and any other style you can dream up. Building a custom unit allows you to meet all your wants and needs revolving around style and functionality. Since the design is completely up to you, they can comfortably seat from 2 to 12 people depending on your vision.
Hot tubs need to be wired to electricity to run the pump circulating water through the jets. Depending on the voltage of the unit, you may need to upgrade your outlet if you intend to plug in, or you may need to upgrade a circuit. Tubs can be 110v, 120v, or mixed voltage, meaning that they may use four wires, two of each kind, to run properly. Based on the voltage needed, you can expect to pay between $1,000 and $20,000.
|Tub Voltage||Cost Range (Installed)|
|110v||$1,000 - $5,000|
|120v||$4,000 - $20,000|
|Mixed Voltage||$8,000 - $20,000|
If you want a tub that runs on 110v and plugs into an outlet, you need a “plug and play” tub. These cost $1,000 to $5,000, depending on the material. They are usually smaller, without as many jets or features, but they circulate water well and provide a pleasant experience.
If you want a larger option with more jets and features, you need a 240v model. Because they are bigger and have more features, they tend to be more expensive, with a cost range of $4,000 to $20,000. These have plugs, which need a 240v outlet, but most are hardwired into your home’s electrical supply.
Some newer models with ozonators, chromatherapy, and other high-end features are wired for mixed voltage, with some features running on 110v and others on 120v. Because these are high-end with many features, they cost more, between $8,000 and $20,000. They require a hardwire installation by an electrician to run properly.
Every hot tub needs a heater to get and keep the water warm. Most come with a standard heater, although some lower-cost and custom models require you to purchase your heater separately. Suppose you purchase a tub you love, but it comes with a gas heater, and you do not have a gas line. You may want to swap it out for an electric or propane heater. Likewise, if you have a gas line to your yard and want to convert your costly electric heater to a less expensive gas heater, you can do this easily.
Heaters come in three basic types, gas, propane, and electric. Many gas and propane heaters are interchangeable. They run on either when set up properly. Keep in mind that if you choose gas, you must have a gas line to your yard or deck to run the heater, increasing your installation costs. Depending on which type you choose, you can expect to pay from $100 up to $1,500.
|Heater Type||Cost Range (Materials Only)|
|Electric||$100 - $500|
|Natural Gas||$800 - $1,500|
|Propane||$800 - $1,500|
Electric hot tub heaters are less expensive to purchase and install than gas or propane heaters. They cost between $100 and $500 on average. These heaters can be hardwired quickly and provide steady, consistent heat. They take longer to heat than gas or propane, and the farther away from your home the tub is, the longer the wire running to your heater. Their repair costs are usually lower, which can be attractive to some homeowners.
A natural gas heater costs between $800 and $1,500 on average. Natural gas heaters are the most common type. They heat water quickly and are one of the lowest costing heat sources available. These heaters need a buried gas line, which can be expensive, especially as it gets farther from the house. Most of them run on propane if natural gas is not available in your area. Always check to see which fuel the heater requires.
For people who do not have a natural gas line but like the convenience and fast heating of a gas heater, propane 6 makes an excellent alternative. These heaters typically use gas as well and have the same costs at $800 to $1,500. You can run pipes from your propane tanks right to the heater the same way you run a gas line. In some cases, you can also purchase a small propane tank just for the tub to lower installation costs or if you do not have propane on your property already.
One of the most important requirements is having a solid foundation for the hot tub. It could be on a concrete slab, patio, prefabricated spa pad, or reinforced deck. The foundation must be level, straight, and bear the weight of the unit, water, and occupants. If you do not have a leveled foundation, it can cost around $950 for a 100 sq.ft. job of concrete leveling. If you do not have a foundation, it costs $800 to $2,000 to install a foundation slab, depending on the size, materials, and installation process.
Another important requirement to keep in mind is the accessibility of the location. The access point into your backyard location should be as wide as your unit is tall. If this is not the case, a crane delivery is needed, which costs from $500 to $1,000. This cost varies depending on the crane size, the travel time to the location, requirements like street closures, permits, and barricades, and the on-site time. Companies often charge an hourly rate with a two to three hour minimum. A few other requirements related to the location are having the equipment panel easily accessible and having it located more than 10 feet away from overhead power lines.
Your final considerations revolve around electricity and water. You must have 120v to 240v for a tub to run. If this is not the case, electricians must dig up the spot and provide these electrical components. The cost to hire an electrician is between $40 and $120 per hour. Last but not least, nearby water access, such as a garden hose, works to fill and clean the tub. It is not required to have plumbing.
The cost to heat a hot tub depends on many factors, including how often you keep it running throughout the year, which varies depending on where you live and the local climate. Typically, the easiest way to figure out the operating cost is to break down average costs per month by estimating the number of days you generally run your unit. Below, we’ll provide the average monthly cost and average annual range for areas with temperate climates.
|Period of Time||Electricity Cost|
|Monthly||$25 - $40|
|Yearly||$75 - $500|
In general, expect costs to fall between $25 and $40 a month. However, many things impact the cost of running your tub per month. This includes the unit's size, electricity and water costs in your area, and what you use to heat the water. However, you can determine how much electricity your unit uses by figuring out how many hours a month you use it and the number of kilowatts the tub uses. Multiply these together to find the total kilowatts per month, then multiply this by the cost of electricity per kilowatt-hour in your area. This gives you a good idea of your costs.
On average, it costs between $75 and $500 to run your unit for a year depending on how long you keep it open. When determining the cost to run a unit per year, you must think about how many months throughout the year you actually run it. This varies depending on where you live and the location of your unit. For example, indoor units can be used far more often than outside ones since the weather isn’t a direct influence. Some outdoor units are designed to be used year-round with superior insulation properties. However, if you do this, you must deal with higher energy costs.
Hot tubs can be very relaxing and enjoyable, but there are some safety protocols. Many come with some safety features to ensure that people enjoy their time in the tub while avoiding danger:
An automatic shut-off feature is an important safety feature to prevent any problems. Suppose the water temperature is set, but the water rises above this setting. In that case, the shut-off feature automatically stops the circulation pump to prevent the water temperatures from rising to extremes. Once the temperature comes back down, the pump continues to work. This automatic shut-off feature comes with many modern-day units and cannot be added to an old one.
Many units use locking covers for when they are not in use. This cover adds a safety feature to ensure there are no trespassers or incidents when it is not in use. Locks often come in the form of straps or clips attached to the cover for easy closing. Expect to spend $15 to $30 for a four-pack of clips or $30 to $60 for a two-pack of straps.
Soft-sided options are a relative newcomer to the field. On average, they cost between $4,000 and $6,000, including $200 to $800 for installation. They are made of high-density foam and are lightweight and portable but highly durable and available in several shapes and colors. The high-density foam holds heat well, so they are more energy-friendly than tubs that lose heat quickly. They are also more convenient because they can plug into a standard 110v outlet and use less than 15 amps of power. That means you don’t have to do any extra electrical work. Some also have heat recovery features in which the heat is recovered from the motor and is transferred to the spa itself. Soft-sided units offer many of the same benefits other tubs have, like jets, lights, and controls, but they have a unique appearance with very thick, rounded sides. Generally, you can set it up and tear it down within an hour. While heavier than inflatable units, a soft-sided unit and accessories weigh under 150 pounds.
Inflatable units are becoming popular and a good choice for those looking for flexibility. They range in price from $500 to $3,000 on average for materials alone, as these types don’t require any complex maintenance. Rather than opting for a solid tub, inflatable models can be broken down and moved anywhere in and out of your yard. Inflatable units do not use jets but rather fans that blow the air around. Materials lose heat much faster than regular models and need to be heated more often. While they are less expensive than regular models, they are more expensive to run. Depending on the climate you live in and the temperature you set, you can expect to pay between $40 and $70 a month in electricity bills alone. This is because they are not as well insulated as permanent installations.
Spillover spas are directly connected to your pool. These spas feature a fountain or waterfall that allows water from the hot tub to “spill over” into the pool. Adding a spillover spa to an existing pool costs more than installing a spa and pool at the same time. On average, costs range from $6,000 to $10,000 to add an attached spa to a new in-ground pool. It costs between $13,000 and $19,000 to add it to an existing pool. When adding a hot tub to your pool, your contractors need to re-plaster the interior of the pool and make modifications to the pool structure, plumbing, electrical components, and more. They will then resurface everything after the installation is complete. Adding a hot tub to an existing pool has many advantages, including an increase in home value and comfort.
Hot tubs come in various shapes and sizes. Knowing the size and weight of yours helps you determine which one you need for your space and what it will take to move it. We will go over the common sizes and how much they weigh empty and filled with water. Knowing the weight of your unit is helpful when it comes to knowing where to put it in your yard or home. This is especially important if you put it on a deck or any platform lifted off the ground. If you end up getting one that is too heavy, you can break the deck or the unit itself and risk potential injuries, too. Here are some of the common sizes and their corresponding weights.
|Number of People||Weight Empty (lbs.)||Weight Filled (lbs.)|
|2 - 4||350||2,200|
|5 - 6||750||4,420|
|7 - 12||800||5,500|
For those who like to exercise before relaxing, swim spa hot tub combos are a great thing to have. On average, they cost $15,000 to $40,000, including installation costs, which range from $300 to $7,000. This small exercise pool uses jets to provide resistance, so it does not take up the same space as a regular pool. It doubles as a hot tub, either with an adjacent area or by switching the position of the jets and turning on the heater. These tend to be larger, with fewer features like seating unless they have an adjacent seating section. They are normally made of acrylic or molded and installed freestanding, in-ground, indoors, or outside. Swim spas can be used all year round since the water is heated, which increases its overall value. Overall costs vary depending on the size of the tub, additional features, and the power source. Electric-powered spas are generally more efficient and cost-effective, too, due to how large swim spas are.
One of the new crazes for hot tubs is a saltwater system. A saltwater model uses a salt cell to produce a pure chlorine 7 solution, but the salt is not the same type found in the ocean. Saltwater options are becoming popular due to their ease of use and how they give skin a softer and silkier feel. Many prefer them over chlorine tubs due to simplified maintenance and longer-lasting water. The initial cost for a saltwater unit is higher to purchase and install than one with a traditional system. Over the years, the cost is offset due to the lower costs of the water supply and test kits than those needed for a chlorine tub. Purchasing a saltwater generator system ranges between $600 and $1,700. Saltwater generators can be added to many tubs, including soft-sided and molded. They are not recommended for wooden tubs because they can damage them. This results in a total cost range of $2,000 to $20,000, depending on the brand and tub. Built-in units require more expensive generator systems, while above-ground models are cheaper. You will also have to factor in the installation costs of a saltwater generator system, which range from $300 to $500 per project.
The cost to move a hot tub depends on several things. Some of them are very light when empty and can be easily moved, with the only additional costs being potentially needing new electrical or gas hookups. Other models are very heavy. If this is the case, expect moving costs to be around $200 to $500, depending on the distance.
A hot tub is a great investment for someone who engages in physical activity. A soak before exercise warms muscles, joints, and ligaments, possibly reducing the risk of injury. After physical activity, a soak may relieve the body of any tension or soreness. It may relieve pain from arthritis and muscle tightness and promote restful sleep.
They require maintenance and, with any water feature on your property comes inherent risk. You need to cover it at all times or have it fenced and kept away from small children and animals to minimize risks. These may not be a good choice for pregnant women or people with blood pressure problems. Always speak to your doctor or another medical professional before using a hot tub.
A hot tub is a perfect environment for bacteria to grow, making proper maintenance extremely important. To properly maintain your unit, things need to be done regularly, such as checking the water chemical levels, cleaning the filter, cleaning the inside of the spa, and airing out the cover. The water chemicals should be checked two to four times per week. This includes using a tester strip to ensure that the pH, alkalinity, calcium, and sanitizer levels are proper. The spa filter should be cleaned every two to four weeks, depending on usage, to remove any dirt or grime that builds up inside. This filter should be replaced every one to two years as fibers loosen over time. A full inside cleaning of the spa should be completed every two months, where the water is drained. A spa cleaner should be used on the surface, and a vacuum can be used to get in the corners. Any debris can be removed using a skimmer net. Lastly, it is extremely important to remove the cover at least twice a week. This gives the inside of the cover a chance to air out and dry the moisture inside. Some companies offer regular maintenance, which ranges in cost between $50 and $300 per month.
Saunas provide many of the potential health benefits of a hot tub, including relaxation, better blood circulation, and promoting restful sleep. These are two different features and two different installations. Saunas are typically indoors because these are enclosed rooms that produce steam. Hot tubs can be used indoors or outdoors and have the user sitting in hot, circulating water. A four-person steam sauna costs from $3,000 up to $6,000 completely installed, while a four-person hot tub costs between $4,000 and up to $8,500 installed with new electrical and gas line hookups.
|Project||Cost Range (Installed)|
|Sauna||$3,000 - $6,000|
|Hot Tub||$4,000 - $8,500|
No matter where you live, the key to a safe, healthy, and enjoyable hot tub is a quality cover. On average, it costs between $75 and $400 to purchase a cover. There are countless advantages to having a cover, with the most important arguably being safety. If you have young children in or around your home, having a secure cover makes your space more safe and secure should they enter the vicinity of the unit unsupervised. Some covers come with locks, which means you can avoid any unexpected guests from trying to use your hot tub. Additionally, a cover keeps it as warm as possible and keeps any leaves or debris out. Having a cover stops the water and chemicals from evaporating over time.
If you like having privacy when you are in the tub, a screen or enclosure is a perfect purchase for you. There are many options to choose from, depending on whether you are looking for a temporary screen or something more permanent. When looking for something temporary and easy to move, a folding screen or gazebo enclosure is a good option. These range in price from $150 to $450. If you prefer a permanent screen enclosure, a fence screen or trellis is a good option and ranges from $200 to $600. These prices vary depending on the sizing, brand, and company.
Steps can make entering and exiting the hot tub much safer and easier. They come in different shapes and sizes and offer a non-slip tread. There are many options to choose from, depending on the number of steps, if you want handrails 11, the material, and if you prefer steps with a storage area. The most basic steps cost $60 but range up to $400.
Having an independent heater for your hot tub makes it easier to heat the water. On average, an independent heater raises the temperature by roughly five to six degrees per hour. An independent heater may be purchased for $150 to $700, depending on the size, manufacturer, and wattage.
Most modern-day units come with a built-in drainage system. If this is not the case, then a pump is a great purchase because it makes it much easier to empty the hot tub. A pump costs between $80 and $250, depending on the size and brand.
If you want to eliminate the hassle of removing the cover every time you go in, a cover lifter is necessary. A cover lifter mounts to the top side of the hot tub and keeps the cover in place while in use. You can choose from a bracket/shelf, manual, and hydraulic-assisted cover lifter. The bracket/shelf cover lifters are the cheapest of the three kinds and range in price from about $150 to $225. The manual cover lifters are of average price between $170 and $275. The hydraulic cover lifters are the most expensive, ranging in price between $250 and $400.
To keep the water clean, many users opt to purchase an ozonator. An ozonator allows fewer chemicals while leaving the water cleaner and eliminating the powerful chemical smell. An ozonator varies in price from $100 to $300, depending on the brand and size.
If you plan on enjoying drinks in your hot tub, then purchasing a drink holder is a great idea. Drink holders come in all shapes and sizes, attaching to the side of your unit. Drink holders are very reasonable in price and range between $25 and $60 per set.
It can be difficult to enjoy your hot tub after dark if you do not have lighting. You have several lighting options. You can either add lighting outside or inside. In-spa lighting seems to be the most popular and eliminates the need for external lighting. The average cost for a hot tub light is around $30 to $60 per light. This depends on the brand, size, type, and color.
A hot tub’s lifespan is between 5 and 20 years. The lifetime depends on the quality of the materials and how well it is maintained over the years.
This depends on the type of tub, size, and material. Costs can be $50 to $500, depending on these factors.
Each tub has kilowatt usage. You can find this information on the unit itself. Multiply this by the number of hours you intend to use it to find the energy usage.
This depends on the tub and where you put it. For many units, yes, you need some type of pad, but gravel can be an alternative for some. Patios, in-ground use, and poolside are other viable options.
This depends on the tub and its material. Three-person models are relatively rare, but they could weigh very little for an inflatable tub or close to 200 pounds.
You can put a hot tub in your basement. This depends on several factors, including the type and size, how you intend to get it into the basement, and whether you have a concrete slab as your basement floor.
This depends entirely on the type of unit, size, and how much you use it. A conservative estimate ranges from $75 to $500 per year.
