BioBidet gives these fit numbers for its bidet seats and attachments:
- A. Bowl length: about 16-1/2 in means a round bowl, about 18-1/2 in means an elongated bowl. Choose the seat shape that matches.
- B. Bolt spacing: under 5.5 in or over 7.5 in will likely not fit.
- C. Bolt holes to tank: at least 1.5 in.
- Toilet type: fits almost all one-piece and two-piece toilets. Deep French curve toilets do not fit well, and custom shapes, such as rectangular toilets, may not fit.
- Attachments: bidet attachments fit under both elongated and round toilet seats.
- BB-2000 power: a grounded 120 V GFCI outlet within reach of the 4 ft power cord. For other electric models, see the power details on the product page.
