Bio Bidet BB-500

4.2(265 reviews across retail listings)

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.

Pros

  • Instant heater means warm water never runs out — at $199 that undercuts every tank-heater rival like the SmartBidet SB-1000 that goes cold in ~30 seconds
  • At roughly 3.5 inches it's one of the lowest-profile electric seats sold, closer to a normal toilet seat than the tall wedge look of the BB-1000 or USPA 6800U
  • Single knob control is genuinely elderly- and guest-proof: turn for pressure, press to switch washes — no remote to lose or misread
  • Dedicated front/feminine wash plus turbo and massage modes, coverage the similarly priced Toto Washlet A2 charges more for
  • Mechanical backup lets you keep washing (ambient temperature) during a power outage — rare at any price
  • Dual self-cleaning nozzles rinse before and after each use, and owners note less splatter buildup than single-wand budget seats

Cons

  • No dryer at all — Bio Bidet reserves it for the $229 BB-550, so budget for TP either way
  • Instant heater runs warm, not hot: multiple Amazon reviewers say max temperature is 'pleasantly tepid,' noticeably cooler than the BB-2000's hybrid system
  • Elongated only, with no round version even planned
  • No deodorizer, no remote, no user presets — the knob resets to whatever the last person dialed in
  • Spray pressure is modest — fine for daily use, but r/bidets pressure-chasers call it a step down from the BB-1000's firehose
  • Only 4.2 stars on Amazon with some early units developing clicking valves or dead heaters inside a year
  • 1-year warranty feels thin for a seat you hope lasts five, and Bemis support requires the original receipt

Common Questions

How hot does the water actually get?
Warm, not hot — multiple Amazon reviewers describe the max as 'pleasantly tepid,' noticeably cooler than the BB-2000's hybrid system. The upside is it never runs out, since the instant heater has no tank to drain.
Is there a dryer?
No — Bio Bidet reserves the dryer for the $229 BB-550, so budget for toilet paper either way. At $199 the BB-500's pitch is endless warm water and a heated seat, not the full comfort stack.
Is it simple enough for elderly parents or guests?
That's its best trick — a single knob controls everything: turn for pressure, press to switch washes, no remote to lose or misread. The catch is no user presets, so the knob sits wherever the last person dialed it.
What happens during a power outage?
A mechanical backup lets you keep washing at ambient water temperature — rare at any price for an electric seat. You lose the heat, not the function.
Does it come in a round-bowl size?
No — elongated only, with no round version even planned. Round-bowl households should look at the HD-7000R or Brondell's SE400 instead.
Bio Bidet HD-7000

4.4(2,071)

Bio Bidet's Home Depot-exclusive value line, still current in 2026 as the HD-7000 (HD-7000R for round bowls). Its 'Fusion Heating Technology' is the same hybrid tank-plus-instant approach as the BB-2000, meaning unlimited warm water at a big-box price: $329 list, routinely $199-249 at Home Depot. You give up the remote for a side panel, but keep the stainless 3-in-1 nozzle, warm-air dryer, heated seat, and night light. An HD-7500 sibling adds a wireless remote.

Bio Bidet's current mid-flagship and the model its own discontinued-products page now points BB-2000 and BB-1000 shoppers toward. Debuted at CES 2024, it pairs unlimited warm water with a wireless remote plus Bluetooth control through the Bemis Living app, in a body a good inch slimmer than the old Bliss. The remote-only BB-1200L variant is a Costco staple at $199-300, while the app version lists at $399 and streets around $299.

4.4(4,000)

The BB-2000's older, cheaper sibling and one of the longest-selling bidet seats in the US — still current in Bio Bidet's 2026 lineup at $359 list, often $299-340 on sale. It keeps the same pump-driven vortex wash and 3-in-1 stainless nozzle but swaps the hybrid heater for a simple tank, so warm water lasts about 30 seconds. A proven value pick if wash strength matters more than endless warm water.

The updated 'Ultimate' version of the USPA 6800, the seat that introduced a generation of Costco members to bidets. The U adds a night light, two user presets, and a dual-sided LCD remote to the proven dual-nozzle platform with warm-air dryer and carbon deodorizer. Still current on biobidet.com at $399 (list $499), though its 600W reservoir heater and early-2010s styling show their age next to the BB-1200. Elongated and round versions are sold.

Bio Bidet's long-running flagship seat (now sold under Bemis ownership) and still the spray-strength benchmark of the category in 2026. Its hybrid heater pairs a small tank with on-demand heating for unlimited warm water, and the vortex wash mode delivers a concentrated enema-grade jet no tankless rival matches. Forbes named it Best Bidet Overall in 2025; it lists at $699 but routinely streets in the $420-500 range.

Bio Bidet's newer upper-tier seat, sold mainly through Costco, that brings auto open/close lid, UV nozzle sterilization, and an enhanced multi-stage dryer down from smart-toilet territory. It lists at $699 on biobidet.com but Costco carries it around $499 with promos dipping to $340 — roughly half what the Discovery DLS costs for a similar hands-free experience. Unlimited warm water, wireless remote, heated seat, and night light are all standard.
