TOTO Washlet S5
TOTO Washlet S5TANKLESS · 4 PRESETS

Fit ledger — need → measured evidence

FOUR PEOPLE, FOUR SETTINGS
Redesigned remote stores 4 user presets — matched here only by TOTO's $1,075 S7A flagship.
BACK-TO-BACK MORNINGS
Tankless instantaneous heating — endless warm water, with no 30-60 second tank to recover between users.
SELF-CLEANING HYGIENE
PREMIST + EWATER+ wets the bowl before use and electrolyses the wand after every single wash.
FITS THE BOWL LINE
19% slimmer than the C5 it replaces — it hugs the bowl instead of perching on top of it.
EVERYDAY COMFORT
Heated seat, warm air dryer and automatic deodorizer as standard — Forbes' Best Upgrade Bidet for 2026.

  The catch — co-equal billing, always

TOTO covers it for one year, and 250 pounds. That warranty is a third of what Alpha and Brondell give you, the seat is rated to the lowest weight limit in this category, and the S5 is new for 2026 with limited long-term reliability data — on the fixture your whole house uses daily.

Dealbreaker? Runner-up №1 gives 3 years and 320 lbs for $271 less ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Don't buy this if…

  • you want a full integrated bidet toilet (one-piece unit), not a seat or attachment for an existing toilet
  • you need a portable or travel bidet
  • you have a wall-hung toilet or non-standard bowl shape

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids

Why the TOTO Washlet S5 is right for you

It avoids every trap below — and for family of 4, no budget cap, it is the pick because it delivers:

Four people, four settings Back-to-back mornings Self-cleaning hygiene Fits the bowl line Everyday comfort
Trap 01

The outlet nobody has

Every electric seat here needs a GFCI outlet within 3-4 feet of the toilet. Most US bathrooms don't have one, and a licensed electrician charges $150-400 to add it — budget that before you buy the seat, not after.

Trap 02

Wrong shape, wrong SKU

Elongated (~18.5 in) and round (~16.5 in) bowls take different seats, and every price in this category is the elongated, cotton-white SKU. Measure your bowl first — the Tushy Cloud has no round version at all.

Trap 03

Warm water with an asterisk

Tank-fed seats run warm for 30-60 seconds and then go cold, which is why the discontinued TOTO C5 at ~$469 is a worse buy than the tankless S2 at ~$420. Non-electric attachments only run warm if you plumb them into a sink hot-water line.
