China Grey Wall Hung Toilet
China Grey Wall Hung Toilet
This section describes the technical characteristics of a vitreous china wall‑mounted toilet finished in a grey glaze, intended for commercial and institutional installations where space efficiency and hygiene are priorities.
Design and Dimensions
The fixture projects 540 mm from the finished wall, with a bowl width of 360 mm and an overall height of 340 mm from the finished floor to the top of the seat rim. The wall‑mounted configuration eliminates the need for a floor pedestal, reducing the installed footprint by approximately 30 % compared with a floor‑standing unit of comparable bowl size.
Mounting brackets are rated for a static load of 400 kg, tested in accordance with ISO 9001‑2015 annex for sanitary ware. The concealed carrier system distributes load across two steel brackets spaced 180 mm apart, minimizing point stress on the wall substrate.
Flush Performance and Water Consumption
The toilet employs a dual‑flush mechanism offering a full flush of 6.0 L and a reduced flush of 4.5 L, selectable via a push‑button actuator located on the wall plate. Flow rates are calibrated to achieve a minimum flush velocity of 1.2 m/s, ensuring effective waste removal while meeting the WaterSense criterion of ≤ 4.8 L per average flush.
The trapway diameter is 55 mm, designed to prevent clogging under typical usage conditions. The glazed interior surface exhibits a roughness average (Ra) of ≤ 0.4 µm, reducing bacterial adhesion and facilitating cleaning.
Material Composition and Finish
The body is formed from vitreous china, a mixture of kaolin, feldspar, and quartz fired at 1240 °C to achieve a water absorption rate below 0.5 % (ASTM C373). The grey glaze is a silicon‑based enamel containing titanium dioxide for opacity and cobalt oxide for hue, providing a uniform color with a ΔE*ab variation of less than 2 units across production batches.
Surface hardness, measured by Mohs scale, rates at 6–7, conferring resistance to scratching from typical cleaning implements. The glaze is also chemically resistant to pH values ranging from 4 to 10, suitable for use with common bathroom detergents.
Installation Requirements
Installation necessitates a load‑bearing wall capable of supporting at least 150 kg per mounting point, with a minimum stud spacing of 400 mm for wood framing or 600 mm for steel studs. The concealed carrier includes adjustable feet allowing vertical alignment within ±5 mm tolerance.
Water supply connections use a ½‑inch NPT male thread, while the waste outlet connects to a 100 mm PVC push‑fit socket. A flexible silicone seal is supplied to accommodate minor wall irregularities.
Typical Applications
- Office restrooms where floor space is at a premium and cleaning schedules demand quick access beneath fixtures.
- Healthcare facilities requiring barrier‑free designs; the wall‑hung configuration allows unimpeded wheelchair transfer.
- Hospitality environments seeking a modern aesthetic; the grey finish complements neutral tile palettes.
- Educational institutions where vandalism resistance is enhanced by the concealed mounting hardware.
Quality Control and Testing
Each unit undergoes a hydrostatic pressure test at 1.5 MPa for 30 seconds to verify seal integrity. Dimensional inspection is performed using a coordinate measuring machine (CMM) with a tolerance of ±0.5 mm on critical mounting hole positions.
Visual inspection of the glaze is conducted under standardized D65 lighting, with a gloss meter confirming a specular gloss of 70 ± 5 GU at 60° angle. Any deviation beyond these limits results in rework or scrap.
Customization Options
While the standard offering is a grey vitreous china wall‑hung toilet, the following parameters can be adjusted per project specification:
- Flush volume: optional 3 L/4.5 L dual‑flush or single‑flush 4.8 L configuration.
- Seat material: polypropylene, urea‑formaldehyde, or soft‑close polymer variants.
- Mounting frame: stainless steel or galvanized steel, with optional anti‑corrosion coating for high‑humidity environments.
- Glaze color: custom Pantone matching available upon request, with minimum order quantity of 200 units.

Frequently Asked Questions
A: The dual‑flush mechanism is preset at the factory; field adjustment requires replacement of the flush valve kit, which is available as a spare part.
A: Each bracket should be anchored into a stud or concrete insert capable of resisting a 150 kg shear load; typical solutions include metal toggles for hollow walls or chemical anchors for concrete.
A: The enamel formulation includes UV inhibitors; accelerated testing shows ΔE*ab < 3 after 500 hours of UV‑A exposure, suitable for indoor bathroom environments.
