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.

Approx. price

~$550

Best for Kohler-loyal households who want a name-brand seat they can buy, return, or service through Lowe's and Home Depot

What owners like

  • +Sold and serviced through Home Depot, Lowe's, and Ferguson — if anything goes wrong you're returning it to a store, not shipping to a bidet specialty importer
  • +Hybrid heating (stored plus on-demand) avoids the hard 30-second warm-water cliff of pure tank rivals like the Bio Bidet BB-1000
  • +UV light sterilizes the stainless wand automatically, a feature Bio Bidet reserves for its $599 Discovery DLS
  • +Automatic deodorizer kicks in on sit-down — a feature the pricier Alpha JX2 and Coway 400S both skip
  • +The remote is repeatedly praised by reviewers with arthritis and limited mobility — big buttons, no reaching for a side panel
  • +The design is a proven decade-old platform (originally the C3-455), so real-world reliability data actually exists

Common complaints

  • −Only a 1-year warranty — Kohler backs a $550 electronic seat for a third as long as Alpha (3yr) or the Discovery DLS (5yr)
  • −The dryer is the weak spot; one Home Depot reviewer scored it '3.5 stars at full price, 5 at a discount' and most still finish with paper
  • −Elongated bowls only — round-toilet owners are out entirely
  • −The C3-455-to-PureWash rebrand makes research a mess: identical seats appear under two names and prices at different retailers
  • −No user presets on the remote, so couples re-adjust temperature and pressure every visit — table stakes on the Alpha JX2 and Coway 400S
  • −Spray tops out mild-to-moderate; nobody cross-shopping a Bio Bidet vortex wash will call this strong
  • −At $540-600 street it's priced against the Discovery DLS and Toto C5, both of which out-feature it on paper

Questions buyers ask

Is the PureWash E820 the same seat as the old Kohler C3-455?

Yes — same K-8298-CR model number, new name. Kohler retired the C3-455 branding, and identical seats still appear under both names at different prices across retailers, so search both when comparison shopping. The upside of the decade-old platform is that real-world reliability data actually exists.

Does the warm water cut out after 30 seconds like tank seats?

No hard cliff — the hybrid system blends stored and on-demand heating, so it avoids the abrupt cold surprise of pure-tank rivals like the Bio Bidet BB-1000. It's not marketed as endless either; think of it as a comfortably long warm window.

Will it fit a round toilet?

No — elongated bowls only, with no round version offered. Round-toilet owners are out entirely and should look at the Brondell LE99 or Alpha JX2, both sold in round fits.

Why buy Kohler over a bidet-specialist brand?

Distribution: it's sold and serviced through Home Depot, Lowe's, and Ferguson, so a problem means a store return rather than shipping to an importer. The remote also gets repeated praise from reviewers with arthritis and limited mobility. The trade: only a 1-year warranty and no user presets, so couples re-adjust settings every visit.

How strong is the spray?

Mild to moderate at the top end — nobody cross-shopping a Bio Bidet vortex wash will call this strong. It's tuned for comfort, with UV wand sterilization and an automatic sit-down deodorizer as the differentiators rather than raw pressure.

Kohler PureWash E930

Kohler's flagship bidet seat, launched at KBIS 2024.

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.
