Rimless Wall Hung Toilet With Soft Close Seat
Rimless Wall Hung Toilet with Soft Close Seat
Overview
A rimless wall hung toilet eliminates the traditional inner rim where bacteria and scale can accumulate. The bowl is mounted directly to a concealed steel frame, allowing the floor beneath to remain unobstructed for cleaning. This configuration is common in commercial restrooms, healthcare facilities, and high‑end residential projects where hygiene and space efficiency are priorities.
Technical Specifications
Overall dimensions: width 360 mm, depth 540 mm, height 340 mm (seat top). The trapway diameter is 45 mm, compliant with EN 997 Class 1 flushing performance. The soft‑close seat operates via a hydraulic damper rated for 30 000 cycles without loss of damping force.
Flushing mechanism: dual‑flush valve offering 3 L/6 L options, actuated by a concealed pneumatic push‑button. Water inlet pressure range: 0.1–0.5 MPa. The toilet conforms to ISO 9001 manufacturing and carries CE marking for European markets.
Key Features
- Rimless bowl geometry reduces crevice area by approximately 70 % compared with conventional designs.
- Wall‑hung mounting transfers load to a steel support frame rated for 150 kg static load.
- Soft‑close seat includes a corrosion‑resistant zinc‑alloy hinge and a polyurethane damper.
- Vitreous china body with a glazed surface roughness Ra < 0.4 µm, facilitating easy cleaning.
- Optional anti‑microbial glaze additive (silver‑ion) available upon request.
Applications
In hospital wards, the rimless design minimizes biofilm formation, supporting infection‑control protocols. The wall‑hung layout permits floor‑mounted cleaning equipment to reach under the fixture, reducing labor time.
Corporate office restrooms benefit from the reduced visual bulk and the quiet operation of the soft‑close seat, which meets acoustic standards for open‑plan environments.
Luxury residential projects specify the fixture for its minimalist aesthetic and the ability to pair with concealed cisterns that maintain a clean wall line.
Materials and Construction
The bowl and tank are formed from vitreous china, fired at 1280 °C to achieve a water absorption rate below 0.5 %. The glaze is a silicate‑based coating that provides chemical resistance to acids and alkalis commonly found in cleaning agents.
The support frame is fabricated from cold‑rolled steel, powder‑coated with a 60 µm epoxy layer for corrosion resistance in humid environments. Load testing confirms a safety factor of 3 under maximum rated load.
Installation and Compatibility
Installation requires a prefabricated steel carrier that slots into a standard 2‑inch (50 mm) wall stud cavity. The carrier includes adjustable brackets for vertical alignment within ±5 mm tolerance.
The concealed cistern is compatible with ½‑inch (15 mm) brass inlet valves and uses a 32 mm outlet waste pipe. Flexible hoses with PTFE lining are recommended to accommodate minor movement.
Quality Assurance
Each unit undergoes a hydrostatic pressure test at 0.6 MPa for 5 minutes to verify leak‑free performance. Flush performance is measured according to EN 997, recording average flush volume and clearance of a 75 g test load.
Surface finish is inspected with a gloss meter; acceptable spec is 70–85 GU at 60° angle. Seat damper is cycle‑tested to 30 000 activations, with torque retention measured after each 5 000‑cycle interval.
Comparison Table
| Parameter | Rimless Wall Hung | Standard Floor‑Mounted |
|---|---|---|
| Bowl Rim Area (mm²) | ≈ 1 200 | ≈ 4 000 |
| Mounting Load Capacity (kg) | 150 (frame) | N/A (floor) |
| Flush Volume Options (L) | 3 / 6 | 4.5 / 9 |
| Seat Close Mechanism | Hydraulic damper | Standard (no damper) |
FAQ
Can the rough‑in dimensions be adjusted? The carrier offers ±10 mm vertical and ±5 mm horizontal adjustment to accommodate variations in wall stud placement.
What information is needed for a quotation? Provide project location, required flush volume, any special glaze (e.g., anti‑microbial), and quantity. A layout drawing of the wall cavity helps confirm carrier compatibility.
Which materials are available for the bowl? Standard vitreous china is stocked; optional finishes include a matte glaze or a colored glaze (subject to minimum order).
How is quality inspected before shipment? Each unit is subjected to hydrostatic, flush performance, and visual inspection; a test report is available upon request.
What packaging methods are used for export? Units are packed in double‑wall corrugated cartons with foam corner protectors, then placed on pallets and stretch‑wrapped.
