Kohler PureWash E820

4.6(500 reviews across retail listings)

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.

Pros

  • 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
  • Retailer aggregate ratings sit around 4.6 stars, with the remote repeatedly praised by reviewers with arthritis and limited mobility
  • The design is a proven decade-old platform (originally the C3-455), so real-world reliability data actually exists

Cons

  • 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

Common Questions

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.

Electric Bidet Seat

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.

Kohler Puretide

Non-Electric Bidet Seat
4.4(3,500)

The big-box default non-electric bidet seat and the anchor of the manual-seat category. The Puretide 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 Home Depot and Amazon staple for years, with thousands of reviews at around $100 in both elongated and round versions.

TOTO's home-center exclusive, replacing the discontinued K300 in the 2025 lineup refresh. Under the lid it's essentially a Washlet S5 — same remote with four user presets, instantaneous heating, EWATER+, PREMIST, night light, dryer, and deodorizer — sold through Home Depot and Amazon at a lower street price (about $500 vs the S5's $650). The trade-off is choice: elongated bowls and Cotton White only. For most buyers it's the value play of TOTO's current range.

Listed at $899 but selling around $525-600 through 2026, it undercuts the comparable Toto S550e by several hundred dollars while adding a 5-year full warranty. Elongated toilets only.

Tushy's top-of-line electric seat, launched late 2024: a motion-sensing auto-open lid, digital temperature display on the seat, wireless remote with screen, endless instant warm water, UV-sterilized stainless wand, and a dryer Tushy claims is twice as strong as the Cloud's. At $599 it's the cheapest way to get an auto-opening lid — a trick that otherwise costs $1,299 on the Toto S7A. Elongated toilets only.
