Needs an outletyes
Heated seatyes

Kohler's flagship bidet seat, launched at KBIS 2024. The E930 is the closest an add-on seat gets to a smart toilet: a motion-activated lid opens and closes hands-free, the Kohler Konnect app adds voice and phone control, and a tankless heater supplies endless warm water. A handheld remote with programmable presets, warm-air drying, a night light, and a UV-sanitized stainless wand round out the list at a Toto-flagship $1,299.

+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

Common complaints

−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

Questions buyers ask

What does voice control require to set up?

More ceremony than you'd expect for a toilet seat: the Kohler Konnect app, a Wi-Fi connection, and a Kohler account. Once configured you can command washes by voice or phone — it's the only seat in this class you can talk to — but if that setup sounds tedious, the handheld remote with programmable presets covers everything important.

Is the warm water endless, or does it use a tank?

Endless — the E930 is tankless, unlike Kohler's own E820 which uses a hybrid tank that can dip during long washes. Combined with the heated seat, dryer, and night light, the water system is genuine flagship grade.

Should I worry about the motorized lid breaking?

It's a fair concern. Motion-activated lids add motors and sensors that simpler seats don't have, and this same complaint pattern dogs the Coway 500S. Kohler's 3-year warranty covers it — notably the same coverage as the $450 E525, so the extra spend buys features, not extra protection.

Does it come in a round-bowl version?

No, elongated only. Round-toilet owners are out entirely on the E930 — within Kohler, the E525 is the model sold in both fits.

How does it compare against the Toto S7A at this price?

The E930's list price sits in S7A territory and both offer the auto-lid trick, but Toto discounts constantly while Kohler rarely does, and the E930's review base is still thin next to Toto's flagships. The E930's edge is app/voice control and Kohler ecosystem matching; Toto's is decades of washlet reliability data and a deodorizer, which the E930 oddly omits at $1,299.

Kohler discontinued the C3-455 name and now sells this exact seat (same K-8298-CR model number) as the PureWash E820 — its current mainstream remote-controlled bidet seat. A hybrid warm-water system blends stored and on-demand heating, and the stainless wand self-cleans under UV light. You also get automatic deodorization, a five-setting heated seat, night light, and quiet-close lid. Retails $540-600 at big-box stores; elongated bowls only.

Kohler / Non-Electric Bidet Seat

Kohler Puretide

The big-box default non-electric bidet seat and the anchor of the manual-seat category. The Puretide — Kohler now sells the same K-5724 seat under the name PureWash M250 — replaces your whole toilet seat rather than bolting underneath it like an attachment: a side lever extends the wand and modulates spray pressure using water-line pressure alone - no electricity, no batteries. It's been a big-box staple for years at around $100, in both elongated and round versions.

Heating: Cold Water Only
Control: Side Lever
Install: 15-30 min DIY
Warranty: 1-year limited

No Electricity Needed
Name-Brand at $100
Integrated Seat Look

Best for Renters and outlet-less bathrooms that want a name-brand step up from a $40 attachment without wiring anything
