You may have seen them in bathrooms during trips abroad: a second porcelain trough, next to the toilet, that looks like a cross between a urinal and a sink. That thing there is a bidet, people! Perhaps you’ve seen real estate listings boasting “luxury master bath with bidet.” So what exactly is a bidet?

Simply put, a bidet is a bathroom fixture designed to clean your nether regions after you use the toilet. You sit, you turn on the faucet, and a stream of water does what you would otherwise take care of with toilet paper. Got it?

Bidets are extremely popular throughout much of Europe, but they’re still a rarity in the U.S. There are a number of theories on why the bidet never took off here. One is that during the great indoor plumbing revolution, bidets happened to be associated with French prostitutes. Another is that Americans are too prudish and/or practical to spend money on two bowel-related fixtures, particularly if space in the bathroom is tight. And then there’s also simply habit. We’ve always done it this way, so why change?

Nonetheless, bidets are slowly steaming into luxury markets. Acolytes say using bidets is more hygienic than using toilet paper, easier on the earth, and easier on your plumbing. No more toilet paper to clog up the drain! (Or less of it, certainly.)

These days, there’s a bidet for nearly every budget and space constraint. Here are your options, and how much they cost:

Stand-alone fixture: Bidets can cost as low as $30 and as much as $6,900 for a higher-end model by Kohler or Toto. In addition, you can count on spending about $220 to have it installed, using your existing plumbing. In total, the average total cost of a bidet, including fixture price and installation, is about $1,100. Modern bidets

Washlet: If you lack the space in your bathroom for a separate fixture, you can replace your existing toilet seat with an electric one, sometimes called a washlet, which will spritz water much like a bidet. Washlets are popular in Asia and prices have dropped in the United States to around $170 to $2,650 for one with additional features like warm water and a blow-dry. Modern bidets Spray attachment: An even cheaper option is to affix a water-spraying attachment to your toilet bowl for as little as $80 and up to $120 for one with a warm water option.

Did you know the average American uses 28 pounds of toilet paper a year—that twice as much as someone in France or Italy. If you install a bidet, you will save around 384 trees,

So how much water does a bidet use? According to Coco bidet maker Biolife Technologies, a bidet uses an eighth of a gallon of water per wash. So it will raise your water bill a bit, but not much (compare that with a single toilet flush, which uses 4 gallons).

You may also want to factor in the labor and grief you’ll save from fewer clogged pipes. And while that’s not wrapped into your water bill, it does put a bidet’s water use into perspective.

Bidet fans swear they’re cleaner. But oddly enough, hardly any research has been done to verify this claim holds water. One study of elderly people in a nursing home showed that bidet use “improved their toileting experience,” yet other studies have revealed a surprising downside: Habitual use of warm-water bidet toilets has a negative effect on vaginal flora. It’s possible that a spray of water can flush the wrong kind of bacteria from one end to the other, increasing your risk of an infection, such as a UTI.

Although they may have cachet for the eco-conscious, real estate agents doubt the bidet will ever take off here in a big way.

“I have never had a client ask specifically for a bidet, and I have never had a client express satisfaction at seeing one while touring a prospective home to purchase,” says Andrea Evers of Evers & Company Real Estate in Washington, DC. “Most clients joke about it if they see one. Like, ‘Oh great, a bidet!’ or even, ‘What is that?’”

“In my 12 years as a broker this has come up, um, zero times,” says Jeffrey Welch of Brown Harris Stevens in Brooklyn, NY.

If anything has sales appeal in American markets, it’s washlets, says Evers.

“I have shown a few homes with those tricked-out Toto toilets that do a lot under the hood, shall we say,” she says. “And clients are much less scared off by those models.” She jokes that they are the bidet of the new age.

So if you’re bidet-curious, understand that it’s not likely to boost the value of your home. If that—along with a special form of cleanliness—is your goal, perhaps a washlet is the way to go.
