Pick the Bio Bidet BB-2000 for continuous warm water and a night light, the USPA PRO for saved user presets and the slimmest profile, or the BB-1000 for the core features with a reservoir-type water system. All three need a 120 V outlet near the toilet, and the BB-2000 manual calls for a GFCI-protected one.

Bio Bidet sells electric bidet seats for round and elongated toilets. The three here all list warm water, a heated seat, a warm-air dryer, a deodorizer, a seat sensor and a wireless remote. The BB-2000 manual names Bemis as the warrantor.
Bio Bidet BB-1000 Supreme: the reservoir model
Choose the Bio Bidet BB-1000 if you want the same core comfort features in a reservoir-type seat. Bio Bidet’s product page (biobidet.com) lists adjustable water pressure and nozzle position, a warm-air dryer, deodorizer, intelligent seat sensor, slow-closing seat and lid, heated seat, warm water, a wireless remote, posterior and feminine wash, massage and vortex spray, and power-saving mode.
The BB-1000 manual (cdn.shopify.com) lists five water-pressure levels, three warm-water and three seat-temperature settings plus room temperature, a thermal fuse, thermal switch and float switch, and a 4-foot cord. Its troubleshooting table refers to a water tank that must fill before spraying, which indicates the seat stores water in a reservoir; Bio Bidet’s BB-1000 page lists “warm water” rather than the BB-2000’s “unlimited warm water.” It is also the largest of the three at 7.28 inches tall.
On October 15, 2026, the standard new offer sold by Amazon.com showed stock with model BB-1000.

Bio Bidet BB-2000 Bliss: unlimited warm water and a night light
Choose the Bio Bidet BB-2000 for continuous warm water. The BB-2000 product page (biobidet.com) calls it Bio Bidet’s flagship and lists unlimited warm water, a stainless steel nozzle, a night light, vortex wash and the same core comfort features as the BB-1000.
The BB-2000 manual (cdn.shopify.com) lists 120 V, 60 Hz and 1,400 W, a water inlet pressure range of 0.04 to 0.74 MPa, a 4-foot cord, five pressure levels, three warm-water and seat settings, a 55 W seat heater, and a 3-year limited warranty from Bemis. It also says the seat must be connected to a grounded 120 V GFCI-protected outlet.
On October 15, 2026, the standard new offer sold by Amazon.com showed stock with model BB-2000.

Bio Bidet USPA PRO: user presets and the slimmest profile
Choose the Bio Bidet USPA PRO if two people share the bathroom and want saved settings. The USPA PRO page (biobidet.com) lists adjustable warm water, a heated seat, warm-air dryer, deodorizer, soft-close lid, night light, a self-cleaning stainless steel nozzle and a wireless remote with user presets; the manual (cdn.shopify.com) explains saving settings to User 1 and User 2.
The manual lists 120 V, 60 Hz and 1,248 W, a 1,200 W heater, water temperature up to 102.2°F, a 70 mL water capacity, a thermal switch, temperature fuse and floating switch, and a water pressure range of 0.07 to 0.74 MPa with 0.1 to 0.69 MPa recommended. It lists the parts in the box, including a T-valve and L-valve, two supply hoses and a mounting plate.
On October 15, 2026, the standard new offer sold by Amazon.com showed stock with model 7ZUSPAPROE 000, the elongated version.

Power: a GFCI outlet within reach
All three run on 120 V. The BB-2000 manual says the seat must be connected to a grounded 120 V GFCI-protected outlet, and the BB-1000 and BB-2000 manuals list a 4-foot cord. Check that an outlet sits within reach of the toilet before you order. If there is none, adding one is a job for an electrician, and a non-electric seat is the alternative; see our Brondell or Kohler bidet seat guides for non-electric models.
Water supply and fit
The seats connect to the toilet’s water supply with the T-valve and hoses supplied; the USPA PRO manual lists both 7/8-inch-to-3/8-inch and 1/2-inch-to-1/2-inch hoses in the box. Check your supply line size before installation day, and if the existing supply line is old or kinked, replace it at the same time; our toilet supply line guide covers sizes and lengths.
Bio Bidet sells each seat in round and elongated versions; the links here are elongated. Our round vs elongated guide and toilet seat size guide show how to measure. Shut off the toilet stop before you begin; our shutoff valve guide covers replacing a stiff one.
Other brands
Choosing between the three
Start with how the bathroom is used. If several people shower and use the bidet back to back, the BB-2000’s listed unlimited warm water is the closest match to that need; the USPA PRO manual lists a 1,200 W heater with only a 70 mL water capacity, while the BB-1000 refills a tank. If two regular users want different settings, the USPA PRO’s User 1 and User 2 presets save them. If the bowl sits close to a wall or vanity, compare widths: the BB-1000 is listed at 17.9 inches wide, the other two at 15.43 inches.
Also compare the manual’s supply-pressure ranges with your home. The USPA PRO manual recommends 0.1 to 0.69 MPa and warns that at its 0.07 MPa minimum the spray may not be adequate.
To compare brands, see our TOTO Washlet guide and American Standard bidet seat guide, or our cross-brand bidet seat guide.

How we chose
This document-based guide makes no hands-on testing claim. We read Bio Bidet’s product pages and owner’s manuals for the BB-1000, BB-2000 and USPA PRO and used their specification tables. On October 15, 2026, all three linked standard new offers were sold by Amazon.com and showed stock. The Slim Zero non-electric seat was excluded because its offer came from a third-party seller.
