A wall hung toilet hangs on a concealed steel frame with the cistern hidden behind the wall or a dummy wall panel. In commercial projects the reasons are practical rather than aesthetic: the floor under the pan stays exposed for mopping, the flush plate and pipework sit at working height instead of at floor level, and the pan height can be set to the project’s accessibility requirement.
What the installation actually consists of
- Concealed frame – carries the pan and the cistern; it must be anchored to the structural wall or braced to the slab, not only to studs.
- Dummy wall or recess – 120 to 200 mm of finished depth depending on frame type; this is the dimension most retrofits run out of.
- Drain connection – horizontal outlet into the frame’s spigot, so the rough-in height and horizontal position are fixed by the frame, not the pan.
- Finish plate – dual-flush plate cut into the panel; the service opening doubles as maintenance access.
Wall hung vs close-coupled vs squat pan
| Aspect | Wall hung | Close-coupled | Squat pan |
|---|---|---|---|
| Floor contact | None – floor fully visible | Full pedestal | Recessed in floor |
| Cleaning around | Mop under and around, no joints | Skirt joint collects grime | Hardest to keep hygienic |
| Install effort | Frame + wall build-up | Lowest | Floor waterproofing critical |
| Retrofit difficulty | High – needs wall depth | Low | High |
| Typical use | Hotels, offices, malls | Housing | Regions with squat habit |
What to check before you order for a project
- Rated load of the frame – the pan is ceramic, the frame is the structural part; ask for the figure rather than assuming it.
- Pan height setting – fixed by the frame leg adjustment, and public projects often have an accessibility requirement; confirm the range, not just one height.
- Spares – flush valves and plates are the parts that get consumed; ordering them with the first shipment is cheaper than air-freighting a valve two years later.
- Shipping – ceramics are palletized and container-loaded; the product page lists the packing basis, and mixed containers with other sanitary ware for building projects are normal.
FAQ
Can a wall hung pan be fitted to an existing wall?
Only if there is wall depth for the frame or you accept a front-facing duct panel. As a rule of thumb, budget the 120 – 200 mm frame depth plus the panel finish before deciding.
Is the pan sold together with the frame?
Pan and frame are separate line items so that projects can mix rated frames with the pan finish they want; tell us the combination when you request a quote.
What information do you need to quote?
Request a quote – Pan model and quantity, destination port, and whether frames and flush plates are included – with that we can quote FOB and container loading in one pass.
