Wall Hung Toilets
A wall hung toilet is a toilet where the cistern is concealed inside the wall cavity or a fixing frame, and only the bowl is visible, mounted directly to the wall with no pedestal touching the floor. Also known as a behind the wall toilet, this design is used in bathrooms where floor space, cleaning access, or a streamlined look are priorities. This collection features wall hung toilet suites from Caroma, Australia's most established sanitaryware brand.
Because the cistern sits behind the wall, only the pan and button plate are visible in the finished bathroom. This makes wall hung toilets a common choice for renovators wanting a statement bathroom feature, particularly in ensuites and powder rooms where clean lines matter. The floor beneath and around the bowl stays completely clear, which also simplifies mopping and general cleaning.
What's involved in installing a wall hung toilet?
Wall hung toilets require a structural in-wall frame (often called a cistern frame or carrier) fixed to the floor and wall studs, which supports the full weight of the toilet and user. This frame sits behind the finished wall surface, so it must be installed before wall linings, tiling, and waterproofing are completed. Plumbing and waste connections are also roughed in at this stage, so the toilet's exact position needs to be confirmed early in the build.
Because of this sequencing, wall hung toilets are best planned during the framing stage of a build or renovation, not retrofitted into a finished bathroom without reopening the wall. We recommend engaging a licensed plumber familiar with in-wall cistern systems, as correct frame installation affects both the toilet's stability and long-term performance.
Do wall hung toilets need more maintenance?
Day-to-day cleaning is generally lower maintenance than a floor-mounted toilet, since there's no pedestal base or floor junction to clean around. The visible components, the pan, seat, and button plate, are cleaned the same way as any other toilet suite.
The cistern mechanism itself is accessed through the button plate on the wall, which can be removed to reach the flush valve and water inlet for servicing. Caroma's Invisi Series button plates are designed for this kind of straightforward access, so a plumber can carry out repairs without needing to cut into tiling or wall linings.
Choosing a button plate
Wall hung toilets are paired with a separate flush button plate rather than a built-in cistern lid. If you're specifying a wall hung suite, see our Invisi Toilet Buttons collection for compatible plate finishes and flush options.
