One Piece Water Closets

One Piece Toilet: Bowl and Cistern in One Moulding

A one piece toilet has the cistern and the bowl made as a single piece of ceramic, so there is no joint between them to leak, to loosen or to collect dirt. It is heavier to carry in than a two-piece and easier to keep clean afterwards. A rimless washdown bowl adds a smooth edge with no hidden channel. Measure the rough-in and the outlet type before choosing the shape.
