Thank you for your inquiry.
Offered bidet seats are deisgned to fit most of 1 pc or 2 pc standard toilets including AS Champion 4.
1pc toilet is a sculpted into a seamless unit, and has no crevices between the tank and bowl.
2pc toilet is one that has a separate tank and bowl which are bolted together upon installation.
Bio Bidet products are designed to fit almost all 1and 2pc toilets. However, there are some exceptions such as category "C" below.
If you have a 1pc toilet with a deep French curve, please contac t us with the make and model of your toilet for a compatibility check.
Please feel free to contact us we can further assist you.
