A wall-hung WC with a flush valve is a modern and space-saving toilet design commonly used in contemporary architecture. It features a toilet bowl mounted directly onto the wall, with no visible base touching the floor, creating a sleek and clean appearance while making floor cleaning easier.
The flush valve, often concealed within the wall or integrated into a sleek flush plate, provides a powerful and efficient flushing mechanism, typically operated by a push button. This design not only enhances aesthetics but also optimizes space, making it ideal for compact bathrooms.
Additionally, the height of the wall-hung WC can be customized during installation, ensuring ergonomic comfort and accessibility. The concealed plumbing and support frame contribute to a minimalist look, aligning well with modern architectural trends focused on simplicity and functionality.

A wall-hung WC with flush valve detail drawing in construction typically includes the following key components and dimensions, described step-by-step:
Wall Structure and Support Frame:
- A concealed steel frame is secured to the wall and floor to bear the load of the WC (typically up to 400 kg or 880 lbs).
- The frame is anchored into solid masonry or stud walls, with bolts and brackets ensuring stability.
Toilet Bowl Installation:
- The ceramic WC bowl is mounted onto the frame using threaded rods extending from the wall.
- The height from the finished floor level (FFL) to the top of the bowl is usually set at 400–450 mm (16–18 inches) for comfort.
Concealed Cistern and Flush Valve:
- The flush valve and cistern are installed within the wall cavity or behind a removable access panel.
- The flush pipe connects the valve to the back of the WC bowl, ensuring a direct water flow for efficient flushing.
Water Inlet and Supply Line:
- A 20–25 mm (¾–1 inch) diameter water supply pipe feeds into the flush valve, typically with a stop valve for maintenance.
Waste Outlet:
- A 100 mm (4 inches) diameter PVC or cast iron waste pipe connects the bowl to the drainage system.
- The outlet is set at the appropriate slope (1–2% gradient) for proper drainage.
Flush Plate or Actuator:
- The flush button/plate is installed flush with the wall surface. It provides access to the internal mechanism for servicing.
Finishing:
- The wall is finished with tiles, waterproof panels, or other desired materials, leaving the flush plate and toilet bowl exposed.
- Access panels may be included for future maintenance of the cistern or flush valve.
