What owners say
Kohler PureWash E525
- +Hybrid heater delivers continuously heated water - no 40-second tank countdown like the SmartBidet SB-1000 or Toto A2
- +UV light automatically sanitizes the stainless wand, a hygiene step the rinse-only wands on most sub-$500 seats skip
- +3-year warranty triples the coverage of Kohler's own pricier E820 and most Korean rivals at this price
- +Sold on the shelf at Home Depot and Lowe's - painless returns and price-matching versus boutique bidet imports
- +Quiet-Close lid and Quick-Release hinges are genuine Kohler hardware; the seat feels sturdier than featherweight Korean plastics
- +Both elongated and round versions, while many rivals in this bracket are elongated-only
- −No warm-air dryer at its $450 list - the similarly priced Alpha UX Pearl dries, deodorizes, and includes a remote
- −Side panel only: you twist to adjust mid-wash, and there are no user presets for couples
- −Skips the night light and deodorizer that Korean seats bundle at $150-300 less
- −Kohler's own E820 at $549 adds the remote, dryer, night light, and deodorizer, which makes the E525's tier awkward
- −Hybrid tank cools slightly during very long washes - true tankless seats like the Moen 5-Series never dip
- −Needs a GFCI outlet within reach - budget an electrician visit in older bathrooms
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
