What owners say
Toto Washlet S7A
- +The proximity-sensor lid opens as you approach and closes when you leave — the definitive hands-free experience, and it can be toggled off from the remote when you don't want it
- +EWATER+ here mists the bowl itself after every use, not just the wand — an S7-family exclusive that keeps the bowl visibly cleaner than the S5's wand-only system
- +At 4.1 inches rear height it's one of the slimmest bidet seats on the market — dramatically lower-profile than the S5's rear hump
- +Two-year warranty doubles TOTO's standard one-year coverage on the rest of the Washlet line
- +Nothing is optioned out: instant heat, heated seat, 95-140°F dryer, night light, and a boosted 'power deodorizer' mode are all standard
- +Auto-flush capable on WASHLET+ compatible TOTO toilets (kit sold separately) for a fully touch-free approach-wash-flush cycle
- −$1,150-1,400 street is S5-money-times-two for the same wash quality — TOTO's own S7 is identical minus the motorized lid, so you're paying ~$300 for the party trick
- −The proximity sensor can't tell a toilet visit from a walk-past — owners with open bathroom layouts report the lid yawning at them every shower until they disable auto-open, defeating the point
- −Elongated bowls only; there is no round version anywhere in the S7 family
- −Auto-flush needs both a compatible WASHLET+ TOTO toilet and a separately-sold kit — on an ordinary toilet you're still flushing by hand
- −Motorized hinges are one more assembly to fail after the 2-year warranty, and the lid isn't a user-replaceable part
- −Only 2 user presets feels thin when the $500 KS6 stores 4
- −1,290-watt draw plus the lid motor requires a dedicated GFCI, and TOTO's manual prohibits extension cords — plan the outlet before the seat arrives
Kohler PureWash E930
- +Motion-activated lid opens as you approach and closes behind you - Toto charges S7A money for the same trick
- +Kohler Konnect app adds phone and voice control, the only seat we track you can command out loud
- +Tankless heating means genuinely endless warm water, unlike the hybrid tank in Kohler's own E820
- +Handheld remote with programmable user presets ends the couples' re-adjustment ritual
- +UV light sanitizes the stainless wand automatically between uses
- +Warm-air dryer, heated seat, and night light complete a true flagship feature list
- −No deodorizer at $1,299 - the $449 Alpha UX Pearl and Kohler's own $549 E820 both include one
- −List price sits in Toto S7A territory, and Kohler discounts far less often than Toto's constant sales
- −Thin review base so far - the 4.8 average rests on a fraction of the reviews behind Toto flagships
- −Elongated only; round-bowl owners are out entirely
- −Voice control needs the Konnect app, Wi-Fi setup, and an account - a lot of ceremony for a toilet seat
- −Motorized lid adds failure points, the same complaint pattern that dogs the Coway 500S
- −3-year warranty is identical to the $450 E525 - triple the spend buys no extra coverage
