Wall Hung Toilet Manufacturers
Wall Hung Toilet Manufacturers
Wall hung toilets are mounted to a concealed steel frame within the wall, transferring load through the frame to the building structure. This configuration eliminates the floor‑mounted pedestal, reducing cleaning surfaces and allowing adjustable seat height.
Key Technical Characteristics
Typical load capacity for the concealed frame is 400 kg static, verified by EN 997 testing. Flush volume ranges from 4.5 L to 6.0 L per flush, depending on the flushing system (dual‑flush or pressure‑assist). Trapway diameter is commonly 55 mm, ensuring compliance with standard drainage codes.
Materials and Construction
The bowl and tank are manufactured from vitreous china with a typical wall thickness of 6 mm to 8 mm, providing resistance to chemical attack and impact. The concealed frame is formed from cold‑rolled steel, hot‑dip galvanized to a minimum coating weight of 275 g/m², giving corrosion resistance in humid environments.
Design and Installation Considerations
Installation requires a load‑bearing wall stud or concrete backing capable of supporting the frame’s reaction forces. The frame includes adjustable brackets allowing vertical adjustment of the bowl within a 50 mm range to meet accessibility standards. Water supply connections are typically 1/2‑inch NPT, with a recommended minimum supply pressure of 0.1 MPa.
Typical Dimensional Specifications
| Parameter | Typical Value | Adjustable Range |
|---|---|---|
| Bowl width (overall) | 360 mm | ±10 mm |
| Bowl depth (from wall) | 520 mm | ±15 mm |
| Seat height (adjustable) | 450 mm | 400–500 mm |
| Flush volume (dual‑flush) | 3 L / 4.5 L | Customizable per project |
| Frame load capacity | 400 kg | – |
Applications
- Commercial office buildings where reduced floor‑mounted fixtures simplify cleaning cycles and meet ADA height adjustability.
- Healthcare facilities requiring hygienic surfaces and the ability to install grab‑bars directly to the wall frame.
- Luxury hospitality projects seeking a minimalist aesthetic with concealed cisterns and customizable flush plates.
- High‑density residential developments where floor space is at a premium and wall mounting frees up usable area.
Quality Assurance and Testing
Each unit undergoes hydrostatic pressure testing of the cistern at 1.5 times working pressure for 30 seconds, followed by a flush performance test measuring volume and cycle time. The vitreous china is inspected for glaze uniformity using a 45° gloss meter, with acceptance criteria above 70 GU.
Customization Options
Manufacturers can adjust the frame geometry to accommodate non‑standard wall stud spacing, provide alternative flush plate finishes (stainless steel, powder‑coated colors), and offer varying bowl shapes (elongated, round‑front) to match architectural themes.
Frequently Asked Questions
What information is required for a quotation?
Project‑specific wall stud layout, desired flush volume, seat height range, and any required accessories such as grab‑bars or flush plates.
Can the bowl dimensions be customized?
Bowl width and depth can be adjusted within ±15 mm of standard sizes; major deviations require new tooling and are evaluated case‑by‑case.
What is the typical production lead time?
Standard models ship within 4–6 weeks after receipt of approved drawings; custom frames or finishes may extend lead time to 8–10 weeks.
How is the concealed frame protected against corrosion?
Frames are hot‑dip galvanized to a minimum 275 g/m² coating and optionally powder‑coated for additional barrier protection in aggressive environments.
