TOTO C5 vs Bio Bidet BB2000 Specs
Seat shape compatibility
The TOTO C5 is designed specifically for elongated toilets, measuring 20.9 inches in length. This shape is standard in most modern American bathrooms.

The TOTO C5 fits elongated models, while the Bio Bidet BB2000 fits round models. Check your toilet dimensions before choosing. This physical constraint is the first filter in your selection process.
Control interface
Both seats offer remote controls for adjusting wash settings. The TOTO C5 remote allows you to set personalized water cleansing options and includes two user memory settings.
