Bio Bidet Slim Zero

Bio Bidet / Non-Electric Bidet Seat

Bio Bidet Slim Zero

Model Slim Zero (7ZSLIMZEROE 000)

  • Warm waterno
  • Needs an outletno
  • Heated seatno

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.

Approx. price

~$82

Best for Anyone who wants the cleanest-looking sub-$100 bidet — a real low-profile seat, not an attachment shim

What owners like

  • +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
  • +Battery night light in the lid gives midnight guidance no other sub-$85 bidet offers
  • +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

Common complaints

  • −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
  • −At ~$82 it's 2.5x the price of a SlimEdge that washes identically — you're paying purely for the integrated look

Questions buyers ask

How do the controls work with just one lever?

Push the chrome lever one way for rear wash, the other for feminine wash, and further for more pressure — the simplest bidet control in existence. One caution: owners with strong house pressure report a startling blast until they master feathering it, since the lever is the only thing modulating flow.

How low-profile is it really?

Four inches at the rear — the lowest-profile non-electric seat around, and it barely reads as a bidet next to the tall humps on electric seats. That integrated look is essentially what you're paying for over a $34 attachment that washes identically.

What does maintenance look like?

The dual nozzles retract behind a guard between uses but have no self-clean rinse cycle, so monthly hand-scrubbing is part of ownership. The lid's battery night light is also dim and chews through batteries in a few months, so many owners just let it die.

Will it fit and hold up on my toilet?

It comes in elongated and round versions across Amazon, Lowe's, and Walmart, so fit is rarely the issue. Durability caveats from reviews: the seat plastic flexes under heavier owners (which can pinch the nozzle path), and taller users say the fixed spray angle lands short since there's no aim adjustment.

Any way to get warm water on this?

No — it's cold-only with no hot-line variant. If ambient-warm washes matter and you're staying under $100, the Luxe Neo 320 Plus attachment does tap-hot water for less, at the cost of the attachment look this seat exists to avoid.

Bio Bidet / Bidet Attachment

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 at major retailers.

Bio Bidet / Electric Bidet Seat

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.
