Tushy Oasis
~$239

Tushy / Non-Electric Bidet Seat

Tushy Oasis

The warm-water version of Tushy's non-electric seat line: same full seat-and-lid replacement as the Wave, but a second EasyTurn knob mixes hot water pulled from your sink's hot line through an included 6-foot hose and brass adapter. Dual self-cleaning DuoFlow nozzles handle front and rear washes, and a quick-release pops the seat off for cleaning. No electricity, no GFCI — warm washes for $239 in round or elongated.

Bio Bidet Slim Zero
~$82

Bio Bidet / Non-Electric Bidet Seat

Bio Bidet Slim Zero

Bio Bidet's slimmest non-electric seat: a complete replacement seat just 4 inches tall at the back with dual retractable nozzles worked by a chrome side lever. Like the Home Depot HD-5000 it's cold-water only with a battery night light in the lid, but it's sold everywhere — Amazon (~$82), Lowe's, Walmart — and has the bigger owner base. For under $100 it's the tidy-looking alternative to strapping a $34 SlimEdge attachment under your existing seat.

Brondell Swash EcoSeat S101
~$89

Brondell / Non-Electric Bidet Seat

Brondell Swash EcoSeat S101

Brondell's non-electric answer to the bidet attachment: instead of wedging a Luxe or Tushy under your existing seat, the EcoSeat S101 replaces the whole seat, with dual retractable nozzles plumbed inside and a chrome side dial metering cold water off your line pressure. No outlet, no cords, no heat — just a cleaner-integrated version of the sub-$100 cold-wash experience, with a slow-close seat and lid included. Street price sits around $85-95 at Home Depot and Amazon.

~$99

Bio Bidet / Non-Electric Bidet Seat

Bio Bidet HD-5000

Verified current in 2026 as models HD-5000E (elongated) and HD-5000R (round). You get a complete replacement seat with dual retractable nozzles, rear and feminine washes, pressure dial, slow-close lid, and a battery-powered night light, all running on water pressure alone.

Tushy Wave
~$189

Tushy / Non-Electric Bidet Seat

Tushy Wave

Tushy's non-electric bidet SEAT — the whole seat and soft-close lid replace yours, hiding the mechanicals that a Classic 3.0 attachment leaves visible in a wedge under your existing seat. DuoFlow gives independent front and rear washes off a discreet EasyTurn knob (bamboo or platinum), nozzles self-clean behind a guard, and a quick-release slides the seat off for cleaning. Cold water only; $169-199 street in round and elongated fits.

Kohler Puretide
~$100

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.
