An indoor pool is a great choice in climates where it may not be warm enough to swim outside too often. It can also be ideal for therapeutic uses, exercise and fitness, or even just as a private indoor oasis for those who choose it. Regardless of your reason for installing one, an indoor pool is not a small investment. An indoor pool is defined as being contained within a structure, whether that is a basement, a sunroom, a screened-in porch, or even a dedicated room constructed specifically for the pool itself.

The average cost of an indoor pool is between $40,000 and $200,000, with most homeowners paying approximately $80,000 for an indoor pool that measures 12’x24’, 40 inches deep, with concrete pool decking, and a fiberglass liner when there is already a structure in place.

For a custom indoor, in-ground lap pool with new structure and a pool size of 25’x45’

Indoor Pool Cost per Square Foot

The cost of building an indoor pool is primarily based on the square footage, or size, of the pool being installed. There are a number of different sizes of pools to choose from. While the 12’x24’ size is most common, those who want a larger pool could install one as big as 30’x50’, and there are a number of other sizes in between. The size of your pool will impact the cost, as reflected in the table below.

Pricing may be cheaper on larger sizes if they are more common, while you may pay more for odd sizes or unique shapes. Typically, most above-ground installations will be cheaper, but special features and other factors may change that, as well. The average cost for an indoor pool ranges from $125-$200 per square foot, depending on these factors.

Since most people will choose to install an inground indoor pool, the costs in the table below reflect pricing for in-ground installation.

Indoor Pool Cost by Material

The material that you choose for your indoor pool will impact how much it costs to install. The average square foot price will vary between types of materials. Typically, fiberglass is the preferred option for modern indoor pools because the shells can be set in place and provide plenty of years of use.

The table below reflects the cost of the pool only, based on the type of material used for its creation.

Indoor Pool Cost Materials

Indoor Pool Cost Materials

Pool materialSizeAverage cost
Vinyl12x24 (288 sq.ft.)$37,000
Fiberglass12x24 (288 sq.ft.)$50,000
Concrete/Gunite12x24 (288 sq.ft.)$60,000

Vinyl Indoor Pool

Vinyl is the most affordable choice for an indoor pool, with most people spending about $37,000 on an inground, 12’x24’ pool. These pools are also available in a number of shapes and sizes, but they do require a lot more maintenance over time compared to the other materials available. These pools will need liner replacements every 10 years, along with other maintenance and care.

Fiberglass Indoor Pool

Installing a fiberglass pool is the most common choice. The shells are available in a number of styles and sizes and can be installed quickly. They do have a higher initial cost, but they are the lowest-maintenance choice and they will provide years of enjoyable use. This pool typically costs about $50,000 to install a 12’x24’ foot pool.

Concrete Indoor Pool

Concrete or gunite pools are some of the most expensive to install and maintain. These pools do offer more shapes and creative designs than fiberglass or vinyl, but they also incur about $27,000 in operating costs over 10 years. This material requires acid washing, more chemicals, and resurfacing, which all add up over time. For the initial installation of a 12’x24’ concrete or gunite indoor pool, you can expect to spend about $60,000.

Indoor Pool Cost by Type

Most people are probably picturing an indoor, in-ground pool when reading this guide. This is a typical installation, but there are a number of options available for an indoor pool installation. Below, we’ll look into installing pools based on their intended use, such as lap pools, heated pools, saltwater, and more. All of these variables affect the cost and each type of pool has its own pros and cons to consider.

In the table below, you’ll see a list of average costs for indoor pools by type. The costs are based on the installation of a 12’x24’ pool, or equivalent, with all labor, materials, and finishing work included in an existing structure.

Indoor Pool Cost Chart

Indoor Pool Cost Chart

Pool typeAverage cost
Indoor above-ground pool$15,000-$35,000
Indoor heated pool$40,000-$70,000
Indoor in-ground pool$37,000-$60,000
Indoor saltwater pool$40,000-$60,000
Indoor endless pool$50,000-$60,000
Indoor lap pool$50,000-$65,000

Indoor Above Ground Pool

One way that people save a lot of money on pool installation is by installing an above-ground model instead of going in-ground. When you consider that it can save you as much as 20% or more, it might be worth a look. For those on a budget, it is possible to spend as little as $8,000 on an above-ground pool when you already have an existing space and there are few installation and maintenance issues to address. Typically, however, for a full installation with additional construction, you can expect to spend $15,000 to $35,000 on an above ground pool that measures 12’x24’.

Indoor Heated Pool Cost

An indoor heated pool isn’t always required, but may be desired by those who want a more comfortable year-round swimming experience. When you choose a heated pool, the only additional expense that you will have to consider is the heater and the electrical work involved to install the unit. A heater will typically add about $4,500 to the average cost, making it around $40,000-$70,000 to install an indoor heated pool.

Indoor Inground Pool Cost

Depending on whether you just need the pool or you need to build the enclosure too, the cost of installing an in-ground pool indoors can vary significantly. Some people spend as little as $30,000 on the project, while others may spend up to $350,000 or more on a huge pool or custom installation. The average cost of an indoor inground pool is about $37,000-$60,000 for a 12’x24’ pool inside of an existing structure.

Indoor Saltwater Pool

An indoor saltwater pool is a great choice for those who prefer a pool with less maintenance and fewer chemicals. When you love to swim but you don’t want the work of a traditional pool or the risk of the chemicals, saltwater is the way to go. However, they also require a saltwater generator and other equipment traditional pools don’t need. As such, the average cost is $40,000-$60,000 to install an indoor saltwater pool that measures 12’x24’.

Indoor Endless Pool Cost

The endless lap pool is one of the most popular choices for indoor use. This pool is unique because it requires a smaller footprint, but still provides all the benefits of swimming laps like you would in a regulation-size pool. Endless pools typically cost between $50,000 and $60,000 depending on their size and the materials used for construction.

Indoor Lap Pool Cost

For those who just want to swim laps, a lap pool could be a cost-effective choice. This pool can be installed in-ground or above the ground, depending on the space available and the budget that you are working with. These pools are ideal for exercise and maximizing space, but they’re not going to be as fun for general swimming. Lap pools typically cost an average of $50,000-$65,000 for in-ground models, but you can get an above-ground lap pool starting at around $10,000.

Indoor Pool Designs

The pool design is another element that will affect the cost of your installation. There are a number of styles on the market today, and each has several different designs that you can choose from, and while rectangular pools are the most affordable, kidney-shaped pools are still rather cheap as well. See the table below to get an idea of the different designs and how much each costs on average.

Indoor Pool Designs

Indoor Pool Designs

Pool designAverage cost
Indoor Plunge Pool$30,000
Indoor Kidney-Shaped Pool$45,000
Indoor Rectangular Pool$45,000
Indoor Classic Pool (Roman/Greek)$70,000
Indoor Lagoon Pool$75,000-$150,000

Indoor Plunge Pools

Plunge pools are newer, but they are one of the most affordable options on the market. These pools are designed for basic swimming and don’t require a lot of space. They are ideal for those who just want a place to cool off and who may not need a whole pool installation that takes up a lot of space. If you want an indoor pool, but are on a budget, consider a plunge design. 

Indoor Kidney-Shaped Pools

Kidney-shaped pools have been around for decades and are one of the most affordable options for those who don’t want a rectangular pool design. They offer a reduced risk of sharp corners and a variety of sizes and configurations for something more visually appealing than a simple shape.

Indoor Rectangular Pools

Rectangular pools are fairly standard in indoor installation. These pools come in different sizes, all the way up to 30’x50’ or more, and can be installed in just about any space. They are cheaper to install because of their shape and they are among the cheapest pools that you can buy for indoor use.

Indoor Classic Pools

Classic designs, such as Greek or Roman pools, are usually simple rectangular designs that add detailed curves and accents for a stylish look. These will typically cost more for the decking and installation because of the detailed features, but they also offer that classic look that people love. Roman pools are known for having half-circles at the ends and rounded corners, while Grecian designs include curves and angles that are similar, but more flowing and less structured. For those who want to add a touch of elegance to simple pool installation, this style could fit the bill.

Indoor Lagoon Pools

Lagoon pools give you the chance to turn your indoor space into a tropical oasis. These pools consist of freeform designs that feature flowing lines, curves, and more natural-looking shapes. For added style, many people also add rocks, grottos, waterfalls, and other designs to their lagoon-style pools. For those who are less concerned with budget and more so with style, this is the way to go. You can even create completely custom designs that will give you a space like none you’ve seen before. Bear in mind that any additional features will add to the price of the basic pool structure.

Cost to Build Indoor Pool

Building an indoor pool is not a small feat. Typically, it starts with a survey of the site and a discussion of the type of pool that will be installed. Once a design and style are chosen, the installer will help you understand the installation process and what it will entail. Typically, in-ground pools will require more installation labor and costs than above-ground models.

You will also have to consider any excavation and construction work on the structure where you will be installing the pool. Excavation and site prep make up about 5-10% of the total project costs for indoor pool installation, with the average homeowner paying around $4,000-$10,000 for swimming pool site excavation. If you don’t already have a structure in place, the costs are going to change significantly. Installing a structure depends on the type of pool and its size, but can range in cost from $50,000 to over $100,000. You will also need to consider the following standard costs:

  • Filter and pump installation, which ranges from $500 to $2,000 on average.
  • Heater or heat pump, which costs about $4,500 for an average installation.
  • Hiring contractors can cost between $65 and $75 per hour, and you may need to enlist the assistance of pool installers, electricians, plumbers, and concrete workers to finish the job.

Basement Swimming Pool Cost

Installing a pool in the basement is a great way to make use of existing space and give your indoor pool a solid foundation. It creates a private oasis in your home and the location means that there is less to worry about in terms of flooding and other insurance or liability concerns. If you have an unfinished basement, the chances are good that there’s a concrete floor that can be used to create the decking, which means you will also incur lower installation costs.

These pools are ideal because they don’t collect dirt and bugs like outdoor pools and they can even be locked and covered with automatic covers for added safety. Something you will need to consider with this installation is whether the basement ceiling will need to be raised to accommodate, but this usually isn’t an issue. In-ground pools are generally the preferred option for basements, but there are above-ground models available.

Basement swimming pools have their own considerations to worry about. For example, you’ll want to stick with that automatic cover to prevent evaporation and reduce humidity issues. You’ll also need to pay attention to lighting to create an inviting space. Most importantly, leave plenty of room in your budget for the heater, filtration system, pump, and a full dehumidification system to ensure that there is no excess moisture buildup in your basement or the rest of your home. Typically, a basement swimming pool costs the same as an indoor pool in other rooms ($40,000-$200,000), although additional excavation or construction modifications may incur additional expenses.

Indoor Pool Dehumidification System Cost

One of the biggest elements of installing an indoor pool is having an appropriate dehumidification system in place. These systems will draw the moisture from the pool out of the air and ensure that moisture doesn’t build up in your walls or elsewhere throughout the structure. These systems come in different styles and price ranges, and you will need to find the one that is right for your pool area. Dehumidification systems can be as cheap as $2,000 for smaller units, or you could spend up to $25,000 or more to have a pool-specific system installed.

Below, you will see a table that lists the average cost of each system for an indoor pool that measures 12’x24’ (288 sq.ft.) and requires an enclosed space of 22’x36’ (792 sq.ft.). For the whole-home system, we estimated a 2,500 square-foot home.

Indoor Pool Dehumidification Cost

Indoor Pool Dehumidification Cost

Dehumidifier typeAverage installed cost
Ventilation-Based System$4,000-$10,000
Mechanical Refrigeration System$4,000-$20,000
Whole-Home System$5,000

There are a few different types of dehumidification systems you can invest in for your indoor pool. A whole-home system certainly isn’t required if you are only trying to keep the pool area dry. However, it can be installed to your existing HVAC unit to create uniform dehumidification throughout the house.

It is ultimately more likely that you will choose a pool-specific system. These units are specifically designed for indoor pools and have more sophisticated features and better humidity controls than a standard HVAC system or freestanding dehumidifier. There are two basic types of pool-specific systems, both of which are discussed below.

Ventilation-Based Systems

Ventilation-based dehumidification systems are designed to use the outside air to create a temperature balance and eliminate excess humidity during colder months. The flaw of this system is that in the summer months, it has no means of cooling the room and that can affect its ability to adequately remove humidity. You can add a cooling coil to this system, but with its limited cooling and dehumidification abilities, it may be best to choose the refrigeration-style system we’ll discuss next. A ventilation-based system will cost between $4,000 and $10,000, depending on the size of the unit that you need.

Mechanical Refrigeration Systems

Mechanical refrigeration systems are another option, and often the more popular one in most climates. These dehumidification systems work by drawing in the warm, humid pool air and passing it over coils that cool the air and condense the moisture to capture it, releasing cool, dry air back out into the pool area. This is the most popular choice for small and mid-size indoor pool installations, and systems average between $4,000 and $20,000, based on the size and type of unit you choose.

Indoor Pool Heat Pump

If you choose to heat your pool, you will have to factor in the added cost of the heat pump. There are a number of styles on the market today, and each has its own pros and cons to consider. You will find heaters ranging in price from about $600 to more than $10,000. Installation costs will vary depending on the type of heater and installation required, with the average homeowner paying $4,500 for the installation and unit.

Indoor Pool Heat Pump Cost Chart

Indoor Pool Heat Pump Cost Chart

Type of heaterAverage cost
Electric Resistance$1,250-$5,500
Heat Pump$2,250-$7,000

Electric Pool Heater Installation Cost

You can install an electric resistance pool heater in your home to assist with heating the pool. Electric resistance heaters work by pumping the water across heated coils and returning it to the pool. An electric resistance pool heater and its installation will cost an average of $1,250-$5,500.

Gas Pool Heater Installation Cost

A gas pool heater is the most popular choice for most pool owners. These can run off of natural gas or propane, although natural gas is typically the more affordable option. They are preferred because they heat water the fastest, and although they are slightly more expensive initially, they offer a lower cost of use over time. A gas pool heater has an average cost of $1,350-$8,000, including installation.

Pool Heat Pump Installation Cost

Electric pumps are the most common choice for inground pool heating. These are different from resistance heaters in their operation and they also use less energy. They are among the most efficient options and will last twice as long as most pool heaters. A pool heat pump and its installation will cost an average of $2,250-$7,000.

Solar Pool Heater Installation Cost

Those who want to save in the long run can choose solar heaters. These will have a higher initial cost, but they will save more money on heating costs in the long run and protect from the risk of huge electricity bills. Solar heaters, however, can only be used in areas with direct sunlight. The size of the pool will determine how many panels you need. Typically, for a 12’x24’ pool with a surface area of 288 square feet, you’ll need 9-10 solar panels. The solar heater and panels have an average cost of $3,100-$11,000, installation included.

Indoor Pool Maintenance Cost

Indoor pool maintenance is much less labor-intensive and less expensive than outdoor pool maintenance, in most cases. If you have a pool that has been properly installed with vapor barriers, dehumidifiers, and all other necessary elements, you won’t spend that much on routine maintenance aside from chemical treatments and occasional cleaning.

On average, you’ll spend about $3,000 to $5,000 per year on maintenance and upkeep. Of course, this could be significantly higher or lower, depending on your exact pool type. For example, concrete pools require resurfacing and vinyl pools will need a new liner about every 10 years. Fiberglass is the most expensive initially, but offers the lowest maintenance costs over time.

Maintenance consists of things like regular cleaning, chemical treatments, and occasional parts repairs or replacements. Many people take on the work of basic care as a DIY project, in which case you would only pay for the chemicals and materials needed.

Indoor vs. Outdoor Pool

Typically, an indoor pool is going to be a bit more expensive to install than an outdoor pool. There are a number of variables involved, including whether you have or need a structure for the pool, whether you’re installing it above ground or in-ground, how big the pool will be, and the need for a dehumidification system. The type of the pool and its size play a role, of course, but generally speaking, it is cheaper to install a pool outdoors than it is indoors.

The national average cost to install an outdoor pool is about $50,000, including a 12’x24’ fiberglass pool with concrete decking. That same size pool for indoor installation averages $46,500, but that is for the pool alone. When you add in the cost of decking, heating the pool, a dehumidification system, and building or properly adapting the structure that will contain the pool, the average cost will increase to about $95,000-$200,000 for indoor pool installation from start to finish. Indoor pools become more expensive because of the additional features and equipment needed to allow them to operate properly.

Indoor vs. Enclosed Pool Cost

A lot of people assume that an indoor pool and an enclosed pool are the same thing. This, however, is not the case at all. When you have an indoor pool, it is typically in a home or other existing building. An enclosed pool, however, can be made simply by building a structure over an existing pool. The biggest difference between indoor and enclosed pools is the freestanding nature of an enclosed pool–it will not typically be connected to the house.

The following table describes the cost of installing an indoor pool in an existing structure and installing an enclosed pool, which will also include the cost of creating the structure.

Advantages and Disadvantages of Owning an Indoor Pool

When considering whether an indoor pool is the right investment, you will certainly want to weigh the pros and cons. Although they may be different for you, depending on your interest in this type of project, here are some of the biggest things to keep in mind. It will be up to you to decide if the pros outweigh the cons, but most people find that they do.

The first benefit of an indoor pool, and the one that leads most people to consider it, is the fact that these pools can be used year-round. It won’t matter what the weather is like or where you live, because you’ll be able to swim whenever you want. These pools also require less maintenance because they are out of the elements. This means they won’t collect as much debris and dirt and they will remain in better condition for longer since they aren’t exposed to the harsh conditions outdoors.

Speaking of exposure, an indoor pool is also going to have the benefit of less sun exposure. This will protect you, your family and friends, and your pool from the harmful UV rays of the sun. Finally, indoor pools provide more privacy and security than outdoor pools. You can even install automatic covers, put locks on the doors, and include additional safety features for added protection.

Of course, choosing to install an indoor pool comes with a huge initial investment. Some people might not have the money to spend in the first place. However, you should keep in mind that upkeep and maintenance with an indoor pool typically cost less over time. This is also a major construction project that will take a lot of time and is fully involved. You’ll need to be prepared for the installation process, so be sure to ask your contractor what to expect.

The biggest concern with installing an indoor pool is the moisture. Humidity and moisture control are critical to the enjoyment of your new pool and the protection of your home. Make sure that you carefully research and install a proper pool dehumidification system to help protect your home from moisture damage, mildew, and even potential mold risks.

Enhancement and Improvement Costs

Pool Waterfall Cost

Installing a waterfall can be a great way to add a unique touch to your pool. If you choose to install a water feature or waterfall, you will typically want to budget an additional $1,000 to $10,000 for the total project. Waterfalls can be purchased in prefabricated designs or custom-designed to your exact specifications. Custom water features will cost more, but this feature typically makes up about 10-15% of the total cost.

Automatic Pool Cover Cost

One of the features that can keep your pool protected and make your life easier is an automatic pool cover. These covers can be installed in indoor and outdoor inground pools, and operate using a motor to unroll the cover across the pool. This will cost $8,000-$10,000 in addition to your existing project costs.

Pool Lighting Cost

Some people choose to install lighting around their pool, either for function or style. The options for pool lighting are as varied as the people installing pools, but the average cost of a good pool lighting installation is around $300-$600 per light for LED fixtures.

Pool Steps

Every pool needs a set of steps to get in and out. Most fiberglass shells include steps to get into an inground pool. They will also often be built into concrete and vinyl pools. Above-ground steps are also available for above-ground pools. Installing pool steps could cost anywhere from $200 to $1,900, depending on the type of pool and steps.

Pool Deck Cost

You are going to need a deck around your pool where people can walk. The material of the deck will typically have the biggest effect on cost. Even in an existing structure, the construction will create a need for new decking. You can install concrete decking or use composite materials. The average cost of a pool deck is about $7,000, with some people paying as much as $12,000 or more for a larger or custom deck creation.

Vapor Barrier Installation Cost

When installing an indoor pool, you are going to need to install a vapor barrier on the structure walls to help prevent moisture buildup. This typically costs between $1,200 and $4,000, depending on the size of the structure. A vapor barrier costs about $0.50 to $0.75 per square foot to install.

Additional Considerations and Costs

  • DIY: Installing a pool is not typically a DIY project. Unless you purchase a “set-and-go” above-ground model, you are going to need the assistance of professional pool installers. If you are going indoors, you will have to also hire experienced plumbers and electricians to ensure the pool is installed and connected to the appropriate systems so that it can filter and pump effectively.
  • Hiring tips: You should always get at least three estimates before you hire someone to install a pool. Everyone has their own construction and installation costs to consider and you may find a better installer or cheaper price if you shop around.
  • Permits: Most indoor pool installations require permits from your municipality. You can check with the pool installers, who may handle permitting for you, or you can call your city offices to determine what kind of permits you need to have to complete this project.
  • Property taxes: Adding a pool to your home can increase your property taxes significantly. First, you are improving the property and adding value. Secondly, some indoor pool installations require the addition of a structure, or the repurposing of unused space, both of which will also add value to the property, thereby increasing tax rates.
  • Home insurance: There is a lot of liability involved in owning a pool. As such, you will typically see an increase in your home insurance rates once you install an indoor pool. Be sure to shop around if you feel the rate is too high, and follow the insurance company’s advice to minimize risk and reduce the increased premiums by integrating as many safety features as possible.
  • Budget-friendly tips: If you want to install an indoor pool, but don’t want to spend a fortune, there are some options. You can choose a smaller size or pick a different pool style that is less expensive. For example, above-ground pools are always going to be less expensive to install than in-ground pools. Another way to save is to choose a fiberglass pool, which is an affordable and durable choice that will provide years of enjoyment. Vinyl is the cheapest to install, but it’s going to require a lot of maintenance and repair over the years, compared to fiberglass that may cost more at first, but will let you essentially “set it and forget it.”


  • Are indoor pools expensive?

Indoor pools are only slightly more expensive than outdoor pools. The biggest expenses are usually related to excavating for an in-ground pool or constructing the indoor space where the pool will be housed. You can get an indoor pool for as little as $15,000 if you are looking for a small, above-ground lap pool or similar model.

  • How expensive is it to build an indoor pool?

The average cost to install an indoor pool is around $95,000, but you could spend as much as $350,000 or more on a custom design and installation. The size of the pool and the structure in which it is enclosed will determine your total costs, along with the material that you choose.

  • Do indoor pools need to be heated?

You can heat an indoor pool, but it certainly isn’t required. Heating a pool is done to make the water more comfortable for swimming. If your pool is indoors in a space that is connected to central heating, you may not need a heater. Alternatively, heating a pool can allow it to be used for therapeutic purposes.

  • How long does it take to build an indoor pool?

A typical indoor pool installation takes two or three weeks, but can be done in less time if there is less construction involved. Every project is different and it depends on the size of the pool and the amount of work that needs to be done.

  • How do you build an indoor pool?

The first thing that you need to do is get a permit, then choose a space, or build a structure that will house the pool. You can excavate the space, have the pool installed, and be swimming in no time. Concrete and vinyl pools will take a lot more on-site construction than fiberglass.

  • Can you put an inground pool in your basement?

A lot of people choose to put inground pools in their basements. This is actually one of the best options because it allows you to have a secure foundation for your pool.

  • How much is a 12x24 inground pool?

Although there are a number of variables involved in exact pricing, the average cost of a 12’x24’ in-ground pool is $50,000. This reflects national average pricing based on fiberglass materials used.

  • How much does it cost to build an enclosed pool?

When you build an enclosed pool, the cost will vary depending on the size of the pool and the structure that you need to construct. Typically, people will spend between $100,000 and $150,000 building an enclosed pool and a new structure to house it.

  • Do swimming pools add value to your home?

Swimming pools do add value to a property. Especially in warm climates, having a pool can often make or break a sale. Of course, they are not without their liabilities (increased taxes and insurance, as well as safety risks), so you’ll have to consider the balance.

  • Is it possible to build the pool now and enclose it later?

Although it is possible to build a pool outdoors and then build an enclosure later, that could make the project costs quite substantial. Some people will do this to save money up front or complete the project in more affordable segments.

  • What's the ROI on an indoor pool?

Pools are notorious for being among the lowest on the ROI scale. With an average return of just 43% at the time of sale, an indoor pool isn’t going to generate a huge return. However, if it’s an important investment to your family, it may be worth the cost.

Cost to install an indoor swimming pool varies greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
