Bidet prices are around $1,090 on average, with most homeowners typically paying between $800 and $1,560. These prices are for traditional standalone fixtures, but costs could run as low as $80 for a toilet attachment. A bidet is one way to clean yourself after using the bathroom by using water instead of toilet paper. While common in Europe and Asia, this bathroom fixture is gaining popularity in the U.S.

2022 Notice: Material Prices Are Surging

Demand for siding and other building materials has grown over the past year. And as a result, manufacturers are increasing materials prices. Prices have gone up 5% to 10% this year, and many parts of the country are experiencing long delivery times. If you're planning a building project, we recommend starting as early as possible in the season, preparing for potential price fluctuations, and allowing extra time to order materials.

What Is a Bidet?

A bidet is a plumbing feature or plumbing attachment that lets you wash your intimate areas after using the toilet. They generally cost more than standard toilet prices, but bidets are more environmentally friendly than using toilet paper and get you cleaner. A few different options are available, including a low-cost portable bidet, a traditional wall or floor-mounted bidet, a bidet toilet, and a toilet seat attachment.

There are several different bidet types to choose from, ranging from low-cost toilet seat attachments to standalone bidets and smart bidet toilets.

Bidet Type Average Price Range (Installed)
Bidet toilet seat$170 – $2,650
Bidet attachment$80 – $120
Standalone bidet$500 – $1,500
Bidet spray attachment$100 – $300
Bidet toilet$1,200 – $2,000+

Bidet Toilet Seat

Also known as washlets, bidet toilet seats typically range from $170 to $2,650, including installation. This type of toilet seat replaces the existing one on a traditional toilet. Seats on the higher price end come with additional features, such as heating or a night-light.

Bidet Attachment 

Some of the most popular brands offer bidet attachments foraround $80 to $120, including installation. Expect to pay at least $120 for a water heating option.

Unlike toilet seats or standalone units, bidet attachments are a separate fixture that goes between your toilet and toilet seat. They’re usually the most affordable option but don’t offer as many features as a traditional bidet.

Standalone Bidet 

A traditional standalone bidet costs anywhere from $500 to $1,500, including installation. A standalone fixture is separate from your toilet. You can expect to pay around $220 for labor and additional plumbing materials. Installing plumbing costs around $1,180.

Bidet Spray Attachment

A bidet spray attachment costs between $100 and $300, including installation. A spray attachment is a basic hand-operated spray arm that connects to the toilet's fresh water supply. Spray attachments are usually mounted to the side of your toilet for easy stowing when not in use. However, these attachments only spray cold water, so they aren't the best choice for those with skin sensitivities.

Bidet Toilet

Bidet toilets cost between $1,200 and $2,000 or more, including installation. Bidet toilets are combination units that feature a toilet and bidet in one, which is great for compact bathrooms. 

These combo units can be fairly simple with hot and cold water without extras, and these are priced at the lower end of the range. Bidet toilets have many features, including Bluetooth connectivity, speakers, deodorizers, night-lights, dryers, adjustable nozzles, massage options, and more. Typically, those with many added extras are priced substantially higher than the purely functional models.

Bidet Installation Cost

Just the installation for a bidet runs from around $200 to $240. Because your bathroom is already connected to proper water lines, the labor isn't as intensive or costly as other plumbing projects. However, if you need to install a properly vented drain—a must for bidets—this could quickly drive up the price by $1,000 total. A drain pipe installation costs around $700.

The most expensive part of a bidet installation is the fixture itself. This project is usually twice or more the cost to install a toilet, which spans from around $220 to $530.

Pros and Cons of Installing a Bidet

Bidets have been in use for centuries in some parts of the world, and many homeowners love this uniquely hygienic addition to their bathroom setup. Whether you choose a budget-friendly spray arm or a high-end smart bidet toilet combo, here are some pros and cons to be aware of.


  • Requires less toilet paper, so it's environmentally friendly

  • Wastes less water because of the high water consumption of producing toilet paper

  • Low-cost options are available for those on a budget

  • Higher-end models offer washing and drying functionality

  • Combination bidet toilets are great space savers


  • Standalone bidets take up space

  • Smart models and those that require electrical hookups are costly

  • Cold water-only options can be uncomfortable when the water touches your skin

DIY Bidet Installation vs. Hiring a Plumber

Some bidet options, such as an attachment, are DIY-friendly. For standalone fixtures or high-end bidet toilets, you'll want to contact a plumber. This type of installation job requires more knowledge and expertise.

Hiring a plumber costs between $50 to $200 per hour. If you attempt a DIY installation and make a mistake, the cost to fix a toilet is $230 on average. Save yourself the risk and money and contact a plumber.


Are bidets eco-friendly?

Yes, bidets are eco-friendly because they reduce or eliminate the need for toilet paper. Interestingly enough, they also use less water despite functioning with water. This is because it takes almost 37 gallons of water to make one roll of toilet paper compared to 1/8 gallons to use this bathroom fixture.

How long does a bidet toilet seat installation take?

It should only take you around 30 minutes to install a bidet toilet seat. However, if you have a standalone fixture, contact a plumber near you to handle the installation. It’ll usually take them less than a day to complete, depending on your plumbing, fixture type, and other variables.

Is it worth it to get a bidet?

While bidets are more expensive than traditional toilets, they’ll save you money on buying toilet paper and are better for the environment. Just from cutting toilet paper costs alone, you could pay for this eco-friendly toilet alternative in the long run. Depending on your lifestyle and usage, it may be a worthy investment.

Does a bidet save you money?

Yes, a bidet can save you money. The average adult spends around $180 per year on toilet paper per person. And energy-efficient bidets only cost around $2 to $20 per month to run. The wide range is due to the array of variables, from how much use the bidet gets to how efficient the unit is. 

Even if you have a low-end bidet with low energy efficiency, a two-person household can still save around $130 after their power bill because they're not consuming toilet paper.

How do you get hot water for a bidet?

Some models with electrical connections can heat water on-demand. Where that isn't an option, the bidet must connect to the household's hot water supply to get hot water, usually by way of the hot water pipe underneath the bathroom sink. Where you need to run a line from the bidet to the sink, the bidet unit should be as close as possible to the sink while not impeding its use to minimize labor costs.
