TOTO WASHLET S5 Bidet Seat vs Bio Bidet Bliss BB-2000

The TOTO S5 is the better-built, more refined seat, and its EWATER+ pre-mist and self-cleaning keep the nozzle cleaner between uses. The Bio Bidet BB-2000 fits both round and elongated bowls, adds a night light and a stainless steel 3-in-1 nozzle, and has far more owner reviews. Buy the TOTO for a known elongated toilet and a preference for TOTO's engineering and remote; buy the BB-2000 for a round bowl, a lower entry point, or if you want the night light.

• Choose the TOTO WASHLET S5 if your toilet is elongated and you want TOTO's proven build, EWATER+ nozzle cleaning and a slim contemporary lid.
• Choose the Bio Bidet Bliss BB-2000 if you have a round bowl, want a night light and a stainless steel nozzle, or want the most-reviewed option.
