Toilet Fitment Guide for the ALPHA JX

The ALPHA JX bidet toilet seat is designed to fit about 98% of residential toilets. Follow this guide to

determine whether or not the ALPHA JX will fit your toilet and what size you require.

One vs Two Piece Toilets

Two piece toilets feature the traditional design of separate tank and bowl

pieces that have been bolted together. If you have a two piece toilet, great!

One piece toilets integrate the tank and bowl into a seamless, molded

design. There are no gaps between the tank and bowl. If your one piece

looks like the one pictured where the tank and bowl meet at a 90 degree

angle with no curves, great!

If your one piece toilet has a curved tank, please read the next section.
