The 10 Best Bidet Toilet Seats
Updated by · How we research
Seven electric bidet seats, a non-electric seat and two attachments compared on warm water, fit, controls and warranty. The TOTO Washlet S5 comes out on top. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.
The wrong shape is the most common reason a bidet seat gets sent back, so measure from the bolt holes to the front of the bowl before you shop. Electric seats also need a grounded outlet within reach of the cord. This list covers heated seats with warm water and simple cold-water options for renters and tight budgets.
Editor's Notes
October 23, 2026, by Ezvid Wiki Admin:
The TOTO Washlet S5 now leads. It warms water as it flows, so the spray doesn't run cold halfway through, and two national review outlets put a TOTO Washlet at the top of their lists. Behind it, the Bio Bidet Bliss BB2000 stays as the value pick with every comfort feature, and the SmartBidet SB-1000 and Luxe Bidet Neo 185 stay too.
Most of the old list had to go. The Conway Bidetmega 400R, Kohler Novita and Genie Bidet 1000 aren't sold anymore. The Toto S550e gave way to the S5, and the old Kohler C3 155 listing now sells the Kohler PureWash E590, which joins with its big side-panel buttons. We dropped the Brondell Swash 1400 because it now costs about as much as the S5 without anything independent to justify that. New picks include the Alpha JX2, the Alpha iX Pure and the TOTO Washlet C5, plus two options for bathrooms with no outlet: the Brondell Swash Ecoseat and the Tushy Classic 3.0.
Nobody publishes noise or spray-strength measurements for these seats, so the ranking leans on what can be checked: heater type, warranty length, bowl fit and which seats three national review outlets and two bidet retailers keep recommending.

Bidets are gaining popularity all around the world. For a premium, Japanese-inspired top-of-the-line model, the Toto Washlet S550e is still the best. But you don't have to spend quite that much for something effective. Both the Conway Bidetmega 400R and Kohler C3 155 cost considerably less but perform almost as well. For that matter, the Kohler Novita is remarkably affordable for a digital model and the Genie Bidet 1000 is as affordable as they get, although doesn't have any advanced controls. Keep in mind when installing any of these that you'll need what's called a backflow prevention valve to ensure that it works correctly without potentially contaminating the rest of your home's water supply.
July 21, 2020:
For this update, the Toto Washlet S550e remains the top selection as it's in a class of its own, most likely because it comes from a Japanese company who supplies bidets and seats all over Asia.
As an alternative to the high priced Toto, we added the Kohler C3 155 that offers an incredible customization of its advanced features, although you won't get the personalized presets, or the automatic opening and closing lid of the Toto.
We continue to include a few non-mechanical choices like the Genie Bidet 1000 and the Luxe Neo 185 for those who can tolerate a cold cleanse in exchange for a much lower price point, or if they don't have a place to plug one in. We updated the Luxe Neo 120 to the Luxe Neo 185, as it offers a second nozzle for better positioning for female cleansing.
The mechanical Astor CB-1000 has been discontinued, so we replaced it with another automatic choice, the Conway Bidetmega 400R. We like this seat because it offers a child mode that adjusts the trajectory of the spray for smaller bodies, and it's remote features Braille on the buttons so that blind users don't need to guess.
March 30, 2019:
Adding an actual bidet to the bathroom is an expensive alteration for most American homes, so the bidet toilet seat is a great compromise. Even this open requires a bit of an investment, so we included the Luxe Neo 120 for those who just want to dip their toe into the experience. Those who like it are likely to upgrade to the more comfortable heated options in the future.
The Toto S550e took the top spot because of it's high quality brand reputation along with providing extra luxury options like tankless water heating, saved user setting and a lid that automatically opens.
Special Honors
TOTO Neorest If you're remodeling rather than upgrading a seat, TOTO's Neorest line builds the washlet into the toilet itself, with an automatic lid, automatic flushing and bowl cleaning. It's sold through plumbing showrooms and dealers rather than as a drop-in seat, costs several times what a premium seat does, and needs a dedicated outlet and a matching rough-in. totousa.com
Electric Seat, Plain Seat Or Attachment
TOTO's S-series, the Alpha JX2 and iX Pure, and the Bio Bidet BB2000 all advertise continuous warm water.
An electric bidet seat replaces your toilet seat and adds warm water and a heated seat, and most add a warm-air dryer, a deodorizer and a night light. A non-electric seat or a thin attachment that slides under your current seat costs a fraction as much and needs no outlet, but its water comes straight from the cold supply line, which can be a jolt in winter (EverFlow).
Among electric seats, the heater matters most. A tank-style seat keeps a small reservoir warm, and a long wash can turn cool once it empties. An instant, or tankless, heater warms water as it flows, so the spray stays warm as long as you need it. TOTO's S-series, the Alpha JX2 and iX Pure, and the Bio Bidet BB2000 all advertise continuous warm water. Good Housekeeping's roundup picks a TOTO Washlet as best overall and a Bio Bidet seat for value (Good Housekeeping), and Wirecutter rates the Washlet S5 highest (Wirecutter).
Controls are the other big choice. A remote can store settings for each person in the house. A side panel is always where you left it and often has bigger buttons, which many older users find simpler. Front, or feminine, wash settings use a softer, wider spray and are standard on electric seats.
Will It Fit Your Toilet And Your Bathroom?
Shape is the first check, and the wrong shape is the most common reason seats get sent back. Measure from the center of the seat bolt holes to the front edge of the bowl: about 16.5 inches means round, and about 18.5 inches means elongated (EverFlow). Some one-piece toilets have a skirted or French-curve bowl that only certain seats fit, so check the maker's fit chart and the seller's return terms before ordering (BidetKing).
Electric seats need a grounded 120-volt outlet near the toilet. Plug straight into a GFCI-protected outlet, never an extension cord, since water and power meet in the seat. If there's no outlet, an electrician can add one, or a non-electric seat avoids the problem.
Water comes from a T-valve that fits between the shutoff valve and the toilet's fill hose. Most seats go on with a mounting plate and that valve in well under an hour, with no cutting or drilling. Use a metal T-valve when one is supplied, since plastic adapters are a common leak point, and check every joint for drips a day later. Attachments such as the Luxe Bidet Neo 185 are made for two-piece toilets with a separate tank.
Warranty, Cleaning And Parts
Warranties vary more than features do. TOTO covers most Washlets for one year, while Alpha, Kohler, SmartBidet and Bio Bidet offer three (EverFlow). A longer warranty matters on a seat that packs a heater, a valve and electronics into a wet room. Return terms matter too: Kohler won't take back an opened seat.
Most electric seats rinse their own nozzle before and after each wash, and some add ultraviolet light or treated water. You still need to wipe the nozzle now and then and slide the seat off its plate to clean underneath. Before buying a lesser-known brand, check that the maker sells replacement nozzles, filters and remotes, because a seat with no parts support is hard to keep running.
Quiet dryers and strong sprays are the makers' own claims, since no outlet we could read publishes noise or flow measurements. Searches of the U.S. Consumer Product Safety Commission recall list found no bidet seat recalls for any brand on this list.
How we researched this
We compared 19 bidet seats and attachments, read makers' feature sheets and seller details for the 10 picks, weighed the recommendations of Wirecutter, Good Housekeeping and CNN Underscored, used two bidet retailers' fit and installation guides, looked at long-running owner feedback, and checked every brand against the U.S. Consumer Product Safety Commission's recall list.
Frequently asked questions
Can I install a bidet seat myself?
Usually, yes. Most seats attach with a mounting plate and a T-valve on the toilet's water line, with no cutting, and take well under an hour. Electric seats also need a grounded outlet near the toilet; if there isn't one, have an electrician add a GFCI outlet rather than using an extension cord.
How do I know if my toilet is round or elongated?
Measure from the center of the seat bolt holes to the front edge of the bowl. About 16.5 inches is round, and about 18.5 inches is elongated. Skirted and French-curve one-piece toilets may need a specific seat, so check the maker's fit chart.
Does the warm water run out?
On tank-style seats it can, during a long wash. Seats with an instant or tankless heater, such as the TOTO Washlet S5, Alpha JX2 and Alpha iX Pure, warm the water as it flows, so it stays warm. Attachments and non-electric seats use cold water.
Do bidet seats have a setting for women?
Yes. Electric seats and dual-nozzle models such as the Brondell Swash Ecoseat have a separate front, or feminine, wash, which uses a softer, wider spray aimed further forward. Electric seats also let you adjust the water temperature and nozzle position.
What happens to a bidet seat in a power outage?
The toilet still flushes normally. An electric seat's wash, heat and dryer stop until power returns, but the seat itself works as a normal seat. Non-electric seats and attachments don't need power at all.
Are bidet seats good for seniors?
Many older users prefer a side panel with large buttons, like the Kohler PureWash E590, and a seat with a high weight rating. Anyone recovering from surgery or with mobility limits should ask a doctor which features would help.
