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.
Specifications
Features
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
- ✓Heated seat with three presets and a soft blue night light round out features usually missing under $200
- ✓Dual self-cleaning nozzles rinse before and after each use, and owners note less splatter buildup than single-wand budget seats
- ✓Whisper-close lid and 7-lb weight make it the easiest Bio Bidet electric to install — most owners report 20 minutes with hand tools
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
- ✗Knob sits low on the right side; larger owners and those with limited mobility report having to lean awkwardly to reach it
- ✗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

Bio Bidet HD-7000
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 BB-1200
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.

Bio Bidet BB-1000 Supreme
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.
