Bio Bidet BB-2000 Bidet Toilet Seat vs Alpha Bidet iX Pure Bidet Seat
Which should you buy? Our verdict on both, pulled from our full The Best Bidet Toilet Seats: 4 Compared (and One to Skip) comparison.
The BB-2000 is the most completely equipped seat here, combining unlimited warm water, a warm air dryer, a heated seat, a deodoriser and a seat sensor in a package Bio Bidet designed for a DIY install. The Alpha iX Pure delivers the same tankless endless warm water in a slimmer, better-looking seat with a far simpler remote.

Buy itThe most completely featured seat here, and one Bio Bidet designed for you to fit yourself.
- Unlimited warm water, a warm air dryer, a heated seat and a deodoriser, so nothing on the comfort list is missing.
- A stainless steel nozzle with adjustable pressure and adjustable nozzle position, plus posterior, feminine, massage and vortex wash modes.
- An intelligent seat sensor, a slow-closing seat and lid, a night light and a power saving mode, in round or elongated.
- Bio Bidet lists overall dimensions of 15.4 by 20.9 by 6 inches but not the seat thickness, which decides how different the toilet feels.
- The feature list is long enough that the remote has a learning curve.
- Bio Bidet says it requires a nearby GFCI outlet.

Alpha Bidet iX Pure Bidet Seat
Buy itTankless warm water and a 4.5 inch rear height, with the simplest remote in the category.
- An energy efficient tankless heating system that Alpha says provides endless warm water.
- Just 4.5 inches tall at the rear with a sittable lid, a slimmer profile than a bulkier seat.
- Arced stainless steel nozzle with adjustable position, oscillation and pulse modes, plus a warm air dryer and heated seat with adjustable temperatures.
- Alpha deliberately leaves out the frills, so there is no deodoriser on this model.
- No published weight or seat thickness beyond the rear height figure.
- Round and elongated are the only choices, with no colour options listed.
