Kohler PureWash E820
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.
Specifications
Features
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

Kohler PureWash E525
Kohler's mid-range bidet seat and its big-box volume seller, stocked at Home Depot and Lowe's alongside the brand's toilets. The E525 pairs a hybrid heater that delivers continuously heated water with a UV-sanitized stainless wand, front and rear wash modes, a heated seat, and Kohler's Quiet-Close lid and Quick-Release hinges. Control is a simple attached side panel - no remote, dryer, or night light - which keeps it a wash-focused seat at $449.97 list.

Kohler
Kohler PureWash E930
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
Kohler Puretide
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
Toto Washlet KS6
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.

Bio Bidet
Bio Bidet Discovery DLS
Bio Bidet's modern tankless flagship, styled like a Toto Washlet rival: a 4.7-inch low-profile seat with motorized auto-open lid, UV nozzle sterilization, endless instant-heat warm water, and a minimalist wireless remote. 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
Tushy Aura
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.
