Bidets have been used in Europe for decades and have begun to grow in popularity in the U.S. With a bidet, you do not need toilet paper after using the toilet since the bidet does the cleaning for you. For some people, this convenient and eco-friendly addition to the bathroom is a positive experience.

Bidets come in many styles and two configurations, oval and elongated. They may require plumbing adjustments to your bathroom, which leads to varying costs. This has an average range of $500 to $1,500 for adding a ceramic floor-mounted bidet to a bathroom, with most people paying around $1,000 total. This project’s low cost is around $400 for a basic bidet installed in a bathroom with existing plumbing. The high cost is around $2,500 for a wall-mounted bidet in a bathroom that needs extensive plumbing and finish work.

What is a Bidet?

At its simplest, a bidet is a bowl-shaped seat with faucets to wash after using the toilet. A bidet can get you cleaner than toilet paper and is more environmentally friendly than other methods. Bidets can be mounted on your floor or wall, and some toilets have built-in bidets or toilet seats with bidet features. A traditional bidet is made from ceramic and designed to be straddled, with the user facing the back of the fixture.

Bidet Cost by Type

Traditional bidets are made of ceramic and installed as a permanent fixture, but there are more types available today. These include everything from portable bidets you can carry to toilets with built-in bidets:

Bidet Cost by Type

Bidet Cost by Type

TypeAverage Costs (Material Only)
Portable Bidet$10 - $50
Spray Attachment$40 - $60
Bidet Toilet Seat (Washlet)$100 - $1,000
Ceramic Bidet$200 - $600
Toilets with Integrated Bidets$1,000 - $1,200

Portable Bidet

If you travel, camp, or want to get clean without paper on the go, a portable bidet makes a lot of sense. Portable bidets cost between $10 and $50 on average and come in many styles, but most have a water container and a spraying nozzle. They are fairly small and discreet, so you can tuck one into your bag or pack it with your luggage or camping equipment. Most are fairly no-frills, but some can change the spray’s force for comfort and better cleaning. 

Spray Attachment

Expect to pay between $40 and $60 on average for a spray attachment. If you are looking for a quick DIY method of adding a bidet to your bathroom, a spray attachment can help. This is a basic hand-sprayer connecting to your toilet’s water supply. They usually come with a T-valve that branches off from your toilet’s water supply to the sprayer. They can mount on the toilet’s side for easy access. However, they only spray cold water. 

Bidet Toilet Seat Cost

Another quick-and-easy solution is the bidet toilet seat. They cost between $100 for a simple seat and up to $1,000 for a seat with many features. These plastic seats take the place of your normal toilet seat and offer a range of features from a simple cold water spray to heated seats, warm water, and even a hot air blow dry. Unless you are using a model with only cold water, you need a plumber, electrician, or both to assist in the installation to make the seat fully functional. 

Ceramic Bidets

Ceramic bidets come in nearly as many styles as toilets. Prices range from $200 and $600 on average, depending on the style. Many are suited to match the nearby toilet, meaning the foot of the bidet may have the same detail or shape. They come in several sizes, including round and elongated fronts and floor and wall-mounted options. They also come in different faucet installation styles, with some having faucets in the front and others having them at the bottom to spray straight up. 

Toilets with Integrated Bidets

Some high-end toilets have an integrated bidet. They cost between $1,000 and $1,200 on average. This is different from a separate toilet seat but offers the same benefits. You need a plumber to plumb for hot and cold water, and most models also require an electrician to wire them for other options. Some of these toilets have many features like the bidet, including MP3 players, Bluetooth, and deodorizers. 

Ceramic Bidets Cost by Type

Bidets come in round and elongated bowl shapes to match the toilet. Of these two, elongated bidets are the most common, but round options are available for smaller bathrooms. Because most bidets are installed beside the toilet, match the toilet’s basic shape for the best appearance. Functionally, there is no significant difference.

Ceramic Bidets Cost by Type

Ceramic Bidets Cost by Type

TypeAverage Costs (Material Only)
Round$200 - $400
Elongated$200 - $600

Round Bidet

Round front bidets are not as common as the elongated form and cost between $200 and $400 on average. They are not as comfortable because they do not have as much space, front to back. However, if your bathroom is short on space or you have a round front toilet, a round front bidet can save space and match your toilet’s shape. Due to the smaller bowl, most round front bidets only have a faucet mounted at the front, rather than below. 

Elongated Bidet

Elongated bidets are the most common and their prices range from $200 to $600 on average. They have a longer oval-shaped seat, rather than circular.  This makes it more comfortable and easier to sit on. Because of the extra space, these bidets often have options for faucet mounting - some models spray from below rather than at you. You can also find more styles for the bidet in this shape. 

Ceramic Bidets Price by Location

There are both floor-mounted and wall-mounted bidets. Ideally, you should choose the model that matches your toilet. If your toilet is floor-mounted, your bidet should be as well. Like a wall-mounted toilet, a wall-mounted bidet needs a special carrier installed in the wall, which increases the unit and installation costs.

TypeAverage Costs (Material Only)
Floor-Mounted$200 - $600
Wall-Mounted$300 - $700

Floor-Mounted Bidet

Floor-mounted bidets are the most common style. Like floor-mounted toilets, they usually receive water from the wall and drain through the floor. The floor holds the weight with a floor-mounted bidet, so beyond the water hook up and the drain, the installation is simple. Once the plumbing is done, the bidet is set in place and bolted to the floor. This also makes replacements easy because the old bidet can be lifted off and a new one set down in minutes if the plumbing is in good condition. These models cost between $200 and $600 on average.

Wall-Mounted Bidet

Wall-mounted bidets are great for contemporary bathrooms. They do not interrupt the floor’s visual, so it can make a small bathroom look larger. Like wall-mounted toilets, a wall-mounted bidet takes more effort to install. This is because the wall needs to be opened and a carrier installed in the wall between the studs. This holds the weight of the bidet and the user. The wall must be refinished after the bidet is installed. The average price for a wall-mounted bidet is between $300 and $700 on average.

Bidet Toilet Price by Brand

There are many bidet manufacturers. Nearly any toilet or bathroom fixture manufacturer has at least one bidet style. If the company makes matching fixtures, such as tubs, toilets, and pedestal sinks, they will likely have a matching bidet. The following are some of the most popular brands and their average costs.

Bidet Toilet Price by Brand

Bidet Toilet Price by Brand

BrandAverage Costs
Omigo$75 - $600
Tushy$100 - $200
American Standard$200 - $400
Toto$300 - $1,200
Kohler$400 - $1,200

Omigo Bidet Price

Omigo makes a series of bidet toilet seats and bidet attachments. They cost between $75 and $600, depending on the model. They have bidet options that are easy to hook up and give you a stream of cold water. They also have heated bidet toilet seats that need professional installation, but that provides a much more customized experience. Their seats can fit most standard toilets, but the colors and finishes are limited. 

Tushy Bidet Price

The Tushy is a bidet attachment connecting to your toilet, and it works with your existing seat. Prices range from $100 to $200 on average. It does not require professional installation or electricity. It delivers a steady stream of cool water where you position it. Because it goes beneath the toilet seat, some seats will be raised slightly, which means they can crack over time. You may need to check to see if your current seat is compatible with the best results. 

American Standard Bidet Price

American Standard is one of the most well-known names in bathroom fixtures. They make full suited lines of ceramic fixtures and faucets. This includes ceramic bidets and bidet faucets. Their bidets come in styles to match their sinks and toilets and colors that match their other ceramic products. Expect to pay between $200 and $400 on average.

Toto Bidet Price

Toto is a Japanese company specializing in toilets.  Their bidets and products cost around $300 to $1,200 on average. In addition to their standard toilet lines, they also make ceramic bidets, bidet toilet seats, and bidet toilets. Their products also come in a full range of styles, sizes, and features. They also offer colors that can match popular finishes from other companies, including American Standard and Kohler.

Kohler Bidet Price

Kohler is a major manufacturer of bathroom and kitchen fixtures in the U.S. They have many suited lines of bathroom fixtures, with most including a matching bidet. They have several stylish options that fit in traditional or contemporary bathroom designs, and they offer them in a full range of colors. They also have a limited range of bidet toilet seats and bidet toilets with Smart features built-in. Their products range from $400 to $1,200 on average.

Bidet Installation Cost

Assuming that your layout can easily accommodate a bidet, the installation process mostly involves the fixture’s plumbing. You need a water line brought to where the bidet is, and the bidet’s drain must be connected to the plumbing system. This may mean opening up the wall, floor, or both near where the bidet will be installed. When opening the floor, the bidet usually covers the opening, but the wall may need to be patched or painted.

Depending on how far the pipes must be run and how difficult the wall and floor materials are to cut through, the entire process takes about 2 to 3 hours on average.

Bidets are installed by plumbers charging between $45 and $200 an hour for most jobs. Because they need to run pipes to the bidet, the job can be simple or difficult, depending on how far the pipes must run. If you have to reroute other fixtures to accommodate the bidet or the plumbing is old and needs updating, this can raise your costs considerably. For an ordinary bidet installation of 2 to 3 hours, the labor costs range from $250 to $600, with most people paying around $500 for installation out of the $1,000 total.

Plumber installing toilet in a bathroom

Bidet Toilet Seat Cost

If you do not have room for a bidet or do not want a stand-alone fixture, a bidet toilet seat or washlet is a good alternative. These attach to your toilet and range from having simple features like spraying water to many features, such as a heated seat, “blow dry” of warm air, and changing water pressure and temperature. You do not need a plumber to install them, but you need an outlet nearby if you choose a model that requires electricity. If you do not already have one, you can install one for around $120 to $200. Bidet toilet seats have a wide range of costs, mostly due to the number of features. The more features a seat has, the higher the cost. It is not uncommon to find a range of prices starting at $100 and going as high as $2,000.

Bidet Toilet Seat Installation Cost

Bidet toilet seats come in many styles. Some are meant to be installed easily DIY. In this case, you need to unscrew your toilet’s water supply, screw on the T couplet, and install the seat. If your bidet toilet seat needs a plumber or electrician to install, expect costs in the range of $200 to $1,000. This range depends on your plumbing and electricity’s layout and how much of the walls the plumber or electrician needs to open. Because most bathrooms do not have an outlet beside the toilet and most toilets are only plumbed for cold water, adding these features raises installation costs. The seat installs easily in minutes, provided the area is ready for the install.

Spray Attachment Prices

A quick and inexpensive option is to add a spray attachment to your toilet seat. Spray attachments come in many configurations, from a frame that fits below your seat to a sprayer and hose that hook onto the toilet’s side. They do not need electricity or special installation, so you can set one up in minutes. Bidet spray attachements have a wide range of costs, you can find them for a range of prices starting at $60 to $150.

Bidet Spray Installation Cost

Your bidet must have a spray feature or faucet to function properly. This can install at either the bottom or front. The position depends on the bidet, and they are not interchangeable. Installing the bidet spray is relatively simple and inexpensive. When installing a new bidet, the spray’s cost is usually included in the installation price. However, if you are replacing the spray, the cost is usually around $50 for the labor, with parts costing between $60 and $150.

Toilets with Integrated Bidets

A fairly new fixture on the market is a toilet featuring an integrated bidet. Rather than a separate toilet and bidet or a toilet with a seat that functions as a bidet, these are toilets with extra features built-in.

Like the bidet toilet seats, you can find a toilet with an integrated bidet with many features. Some are basic, offering just the water spray, while others have integrated MP3 players, heated seats, deodorizers, and more. They are not as common as the other options and cost significantly more, around $1,000 - $1,200, but they install like a standard toilet and do not need as much space. They require a nearby outlet to function, however.

Portable Bidet Prices

Portable bidets are an inexpensive solution to keep clean on the go. They are good for travel and camping and are usually fairly small and discreet. They take no special knowledge or materials, so they are perfect for anyone. Porable bidets have a wide range of costs, you can find them for a range of prices starting at $10 to $20.

Pros and Cons of a Bidet

Many people enjoy using a bidet and the convenience it brings. There is no need for toilet paper with a bidet. So, you have lower monthly expenses, do not need to worry about the ecological impact of paper, and may have fewer toilet clogs. Bidets are considered more sanitary by some and provide a custom experience in the bathroom.

However, bidets take up a lot of space. Every bidet requires a minimum of 30 inches, with 36 inches being the recommended amount. It also needs to be installed near the toilet for best use, and the toilet also requires 30 to 36 inches. For a small bathroom, adding a bidet may require major renovations. Even in larger bathrooms, it may mean relocating cabinetry or other plumbing to better accommodate the bidet.

Bidet Maintenance

Bidets are easy to clean and maintain. The ceramic is easily wiped down with a cloth and bathroom cleaner. Because the bidet does not handle solid waste, it is easy to keep clean and less likely to stain.

Bidet toilet seats can also be wiped down with a soft, damp cloth as needed. Sometimes, a bidet seat or spray clogs from hard water. If this happens, soak the nozzle in vinegar to dissolve the clog and flush with clean water.

Additional Considerations and Costs

  • A bidet is used after using the toilet and is not made for urination or defecation. It cannot flush or process toilet paper.
  • Travel bidets are an inexpensive option that requires no installation. These function similarly to a spray bottle - point it upward and squeeze.
  • Bidets may be a more eco-conscious choice because they conserve trees by cutting back on toilet paper manufacturing and use.
  • While most bidets are designed to be straddled, some permit you to sit to the side if your clothing does not allow straddling. Otherwise, you may need to remove clothing to use the bidet properly.
  • After using a bidet, you need to dry off. Some people have a nearby towel, while others prefer toilet paper. Some bidet toilets and toilet seats have an air-dry option.


  • Can you add a bidet to a regular toilet?

While you cannot add an actual bidet, you can add a bidet attachment or bidet toilet seat to your existing toilet.

  • Does a bidet add value?

Bidets are still very uncommon and do not usually add value to a home.

  • How do you dry after using a bidet?​

You can use a towel or toilet paper in most cases, while some bidet seats have an integrated blow-dry option.

  • Why do bidets not have seats?​

Using a bidet is meant to be quick, and the straddling position does not lend itself to a seat.

  • Why are bidets not popular in America?

There are several reasons why this may be. It could be the culture and the marketing of toilet paper and the need for additional space. Most existing bathrooms cannot hold them without extensive renovation.

  • Are bidets eco-friendly?

Most people consider the bidet to be more eco-friendly than the standard use of toilet paper. However, this varies depending on how much water you use and whether you choose a model with heated seats, deodorizers, hot water, and other features or a simple version that uses only cool water.
