About Wall-Hung & In-Wall Tank Toilets toilets

A wall-hung toilet is bolted to a steel carrier inside the wall — not to the floor. The tank is hidden between studs, the bowl floats six to ten inches above the tile, and the only surface element is a slim flush plate. It's the design move that defines European-styled bath remodels in the US and the format that's exploded in luxury condos since around 2018.

1. You need a deeper-than-standard wall. The carrier (the steel frame the bowl bolts to, holding the tank inside) is 8" deep — meaning you need a 2x6 framed wall, or you need to bump out a 2x4 wall by furring or building a knee-wall bump-out. Retrofitting a wall-hung into a 2x4 wall almost always means a bump-out.
2. The carrier is the real product — not the bowl....
