Kohler PureWash E930

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'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.

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 flagship seat, topping the 2026 lineup with a motorized auto-opening and closing lid, EWATER+ misting for the bowl as well as the wand, instantaneous heating, night light, power deodorizer, and a backlit horizontal remote. At 4.1 inches rear height it's among the slimmest seats sold, offered in Classic or Contemporary lid styles and Cotton White or Sedona Beige. MSRP is $2,005 but street pricing runs $1,150-1,400; pair it with a WASHLET+ TOTO toilet for hands-free auto-flush.

TOTO's 2023-generation flagship, one rung below the S7A we also track — and the two are near-identical: same instantaneous heating, EWATER+ bowl-and-wand sanitizing, PREMIST, 4-user presets, and illuminated remote. The only real difference is the S7A's motorized auto open/close lid; the S7's lid is manual. Sold in Classic or Contemporary lid styles, Cotton White or Sedona Beige, elongated or round, at roughly $1,030-$1,225 street.

A purpose-built accessibility seat from Dignity Solutions, designed with aging-in-place specialists rather than spa-feature checklists. One AUTO button runs a complete 60-second oscillating wash followed by a 3-minute warm dry — no paper, no second step — and the jumbo color-coded remote has the largest buttons in the industry. Instant heating, deodorizer, night light and a 300-lb sittable lid round it out. Its successor, the Infinity Eaze Z3, launched at $1,199, but the Cascade 3000 still sells at $899 with the same 4-year full warranty.
