Bio Bidet
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 review base. For under $100 it's the tidy-looking alternative to strapping a $34 SlimEdge attachment under your existing seat.
Specifications
Features
Pros
- ✓Lowest-profile non-electric seat around — 4 inches at the rear means it barely reads as a bidet, unlike the tall humps on electric seats
- ✓Chrome side lever is the simplest bidet control in existence: push one way for rear, the other for feminine wash, further for more pressure
- ✓Real replacement seat eliminates the gap-and-wobble complaints that fill Tushy Classic and SlimEdge attachment reviews
- ✓840+ Amazon reviews at 4.1 stars with a long track record since 2018 — the failure modes are known and minor
- ✓Battery night light in the lid gives midnight guidance no other sub-$85 bidet offers
- ✓Ten-minute, plumber-free install — several reviewers with zero DIY experience report first-try success
- ✓Dual retractable nozzles tuck fully behind a guard between uses, staying cleaner than fixed attachment nozzles
- ✓Sold in both elongated and round versions across Amazon, Lowe's, and Walmart, so there's always a deal somewhere
Cons
- ✗Cold water only with no hot-line variant — if you want ambient-warm washes, the Luxe Neo 320 Plus attachment does tap-hot for less
- ✗Water pressure is entirely lever-modulated; owners with strong house pressure report a startling blast until they master feathering it
- ✗No nozzle aim adjustment, and taller users say the spray angle lands short
- ✗The seat plastic flexes under heavier owners, which can pinch the nozzle path — same complaint as its HD-5000 twin
- ✗Night light is dim, un-aimable, and chews through batteries in a few months
- ✗Nozzles have no self-clean rinse cycle, so monthly hand-scrubbing is part of ownership
- ✗Lid isn't rated for sitting, which surprises people used to solid enameled-wood seats
- ✗At ~$82 it's 2.5x the price of a SlimEdge that washes identically — you're paying purely for the integrated look

Bio Bidet HD-5000
A $99 non-electric bidet SEAT — not an attachment — sold exclusively through Home Depot, now badged under parent brand Bemis. 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. Note: despite the price it is not an electric seat — no heat anywhere.

Bio Bidet SlimEdge
The SlimEdge is Bio Bidet's (now Bemis-owned) answer to the biggest complaint about bidet attachments: the wedge of plastic that tilts your seat. Its body is roughly 50% thinner than typical attachments, so the seat sits nearly flush, while still packing dual nozzles — rear plus a dedicated feminine wash — controlled by a single side lever. Cold water only, no electricity, $59 list but routinely $30-35 on Amazon, where it holds 4.4 stars across 32,000+ reviews.

Bio Bidet BB-500
Bio Bidet's current entry-level electric seat, launched in late 2023 as the spiritual successor to the BB-600. The headline trick is an instant heater with unlimited warm water inside an ultra-slim 3.5-inch body — a combo that usually costs $300+. Everything runs from a single multi-function side knob: turn for pressure, press to cycle rear, front, turbo, and massage washes. A BB-550 sibling adds a warm-air dryer for about $30 more.
