A bathroom in wall toilet hides the cistern inside the wall cavity, leaving only the pan and a slim flush plate on show. At QA Bathroom Warehouse in Perth, we stock in-wall cistern systems, wall hung pans and matching flush buttons at warehouse prices from our Malaga showroom.

How In Wall Systems Work

The concealed cistern and steel frame mount inside a stud or furred-out wall, carrying the weight of a wall hung pan and hiding all plumbing. The result is a floating pan that is easy to clean under and a wall face broken only by the flush plate — available in finishes like matte black to match your tapware. Plan the wall build-out early: the frame needs cavity depth, and the flush plate position is set before sheeting and tiling.

Pans, Plates and Alternatives

Our in-wall range is deliberately focused — quality cistern frames, rimless wall hung pans and a choice of flush plate finishes. If your wall cavity can’t take a frame, a back to wall suite delivers a similar built-in look with a standard concealed-trap cistern and no wall works. Bring your wall details into the Malaga showroom and we’ll confirm what fits before you buy.
