Hello,

Thank you for your question. There is no particular manufacturer that we recommend over another. What is important is the type of toilet used.

One piece toilets have the toilet housed in one complete unit where two piece toilets have a separate bowl and tank. Offered Bio Bidet seat models are designed to fit all 2 piece toilets and most of 1 piece toilets. The only exception will be rare types of one piece toilets with severe French curves where the toilet tank connects to the base of toilet such as type C (see picture above).

TYPE A and B : YES , TYPE C : NO
