A bidet toilet seat is one of the easiest, highest-satisfaction upgrades you can make to a bathroom — and installing one is a 30-minute DIY job that taps into your existing water supply. The big decision is electric (heated seat, warm water, dryer) vs. non-electric (simple, no outlet needed).
Here are three I’d recommend, from a premium electric seat to a no-frills pick. You will need an outlet near the toilet for the electric models.
Best Overall: TOTO Washlet Electric Bidet Seat
TOTO basically invented the modern bidet seat, and the Washlet is the gold standard: warm water, heated seat, adjustable spray, and a self-cleaning wand. Build quality and reliability are excellent. If you want the full spa experience and buy-it-once quality, this is the one. Needs a nearby outlet.
Best Value Electric: Bio Bidet Electric Bidet Seat
Bio Bidet packs most of the premium features — warm water, heated seat, adjustable nozzle — at a noticeably lower price than TOTO. A great way to get the heated, warm-water experience without the top-tier cost. Also needs an outlet.
Best Non-Electric: Non-Electric Bidet Attachment Seat
No outlet near your toilet? A non-electric bidet seat or attachment uses your existing water line for a clean, refreshing spray with zero electricity. No heated seat or warm water, but it’s inexpensive, dead simple, and installs in minutes. The easiest entry point to bidets.
How to Install a Bidet Toilet Seat
- Turn off the toilet’s water supply and flush to empty the tank.
- Remove your existing toilet seat (two bolts at the back).
- Mount the bidet seat’s bracket and slide the seat on per the instructions.
- Disconnect the supply line at the tank, install the included T-valve, then reconnect the tank line and run the bidet’s hose from the T-valve.
- For electric models, plug into a nearby GFCI outlet. Turn the water back on, check for leaks, and test.
FAQ
Do bidet toilet seats need electricity?
Electric models (with heated seats, warm water, and dryers) need a nearby GFCI outlet. Non-electric bidet seats and attachments use only your existing water line and need no power — they spray room-temperature water. If you have no outlet near the toilet, go non-electric or add an outlet.
Are bidet seats hard to install?
No — it’s one of the easiest bathroom upgrades, usually about 30 minutes. You remove your old seat, mount the bidet seat, and tee into the existing toilet supply line with the included valve. No special tools or plumber required for most installs.
Will a bidet seat fit my toilet?
Most bidet seats come in round and elongated versions to match standard toilet bowl shapes — measure your bowl and pick the matching size. Check the seat’s listed dimensions and mounting-hole spacing (standard on nearly all toilets) before buying.
Bottom Line
For the full heated, warm-water experience, the TOTO Washlet is the buy-it-once choice; the Bio Bidet gets you most of those features for less. No outlet near the toilet? A non-electric bidet seat is a cheap, simple win. All install in about half an hour by teeing into your existing supply line.
