China Wall Hung Bathroom Vanity Unit With Sink
China Wall Hung Bathroom Vanity Unit with Sink
Overview
A wall‑hung vanity unit combines a vitreous china basin with a supporting chassis that mounts directly to the wall studs. The design eliminates floor‑standing cabinets, providing clear floor space and simplifying cleaning in commercial restrooms, hotels, and high‑end residential bathrooms.
The unit is supplied as a pre‑assembled module, reducing on‑site labor and ensuring alignment between basin and support frame.
Design and Construction
The basin is formed from high‑grade vitreous china, fired at 1240 °C to achieve low water absorption (<0.5 %) and high chemical resistance. The wall‑mount bracket consists of cold‑rolled steel, powder‑coated for corrosion protection, and incorporates concealed adjustment screws for leveling within ±2 mm.
Integrated overflow and drain outlets are positioned to meet ASME A112.19.2 standards, allowing connection to standard 1½‑inch P‑traps without adapters.
Edge detailing includes a 2 mm radius chamfer to reduce stress concentration and facilitate smooth cleaning.
Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Overall Width | 600 mm – 900 mm (customizable) | Determined by project layout |
| Overall Height (including basin) | 800 mm – 850 mm | Adjustable via bracket |
| Basin Depth | 180 mm – 210 mm | Measured from front rim to overflow |
| Wall‑Mount Load Capacity | 150 kg (static) | Tested per EN 14688 |
| Water Absorption | ≤0.5 % | Vitreous china standard |
| Finish | Gloss white, optional matte or colored glaze | Custom glaze available upon request |
Material Properties
Vitreous china provides a non‑porous surface that resists staining, bacterial growth, and chemical attack from common cleaning agents (pH 4‑10). The steel bracket undergoes a zinc‑phosphate pretreatment before powder coating, delivering a salt‑spray resistance of >500 hours per ASTM B117.
Thermal expansion coefficient of the china is approximately 4.5 × 10⁻⁶ /°C, ensuring minimal dimensional change under typical hot‑water supply temperatures (up to 65 °C).
The combined system achieves a deflection of less than 0.3 mm under a 100 kg load, verified by finite‑element analysis.
Installation Considerations
Mounting requires anchoring the bracket to at least two wall studs or a certified metal backing plate using M8 × 60 mm lag screws. Leveling screws allow compensation for wall unevenness up to 5 mm.
Plumbing rough‑in should position the waste outlet 200 mm above finished floor, with a 40 mm offset from the wall to accommodate the trap.
Flexible hoses are recommended for supply connections to absorb minor movements and reduce stress on the ceramic.
Applications
The wall‑hung configuration is ideal for environments where floor space must remain unobstructed for accessibility, such as ADA‑compliant restrooms, surgical suites, and laboratory wash stations.
In hospitality settings, the elevated basin improves ergonomics for guests and reduces water spillage on flooring, lowering slip hazards.
Retail and office buildings benefit from the streamlined appearance, which simplifies cleaning routines and supports a modern aesthetic.
Quality Assurance
Each unit undergoes a three‑stage inspection: dimensional verification (±1 mm tolerance), glaze uniformity check under 45° lighting, and hydrostatic pressure test at 0.6 MPa for 5 minutes to confirm leak‑free seals.
Bracket coating adhesion is measured by cross‑hatch test (ASTM D3359) with a minimum rating of 4B.
Statistical process control monitors key parameters such as firing temperature and glaze viscosity, maintaining a CpK > 1.33 for critical dimensions.
Customization Options
- Basin width: 500 mm to 1200 mm in 50 mm increments
- Glaze colors: standard white, ivory, gray, or custom RAL‑matched hues
- Overflow styles: traditional, concealed, or slot type
- Integrated accessories: soap dispenser, towel bar, or LED lighting channel
- Mounting hardware: stainless‑steel or galvanized brackets for corrosive environments
All customizations are supported by engineering review to ensure structural integrity and compliance with local codes.
Frequently Asked Questions
Can dimensions be customized?
Yes. Width, height, and basin depth can be adjusted to suit project specifications. Provide rough‑in drawings for quotation.
What information is required before quotation?
Required details include overall width, desired glaze finish, overflow type, any accessory integrations, and wall substrate type (stud, concrete, or metal backing).
What materials are available for the bracket?
Standard is cold‑rolled steel with epoxy powder coating. Optional upgrades include stainless‑steel grade 304 or hot‑dip galvanized steel for high‑humidity or chemical‑exposure areas.
How is quality inspected?
Inspection covers dimensional accuracy, glaze finish, coating adhesion, and hydrostatic sealing. Test reports are available upon request.
What packaging methods are available?
Units are packed in double‑wall corrugated cartons with corner protectors and foam basins. Palletized shipping includes stretch wrap and shock‑watch indicators.
How are export shipments protected?
Cartons are lined with moisture‑barrier film, and pallets are fumigated per ISPM‑15. Additional corner braces and edge guards minimize impact damage.
What is the typical production lead time?
Standard configurations ship within 3‑4 weeks after receipt of approved drawings. Custom glaze or accessory integration may extend lead time by 1‑2 weeks.
How are samples arranged?
Sample units can be supplied via air freight with the customer covering shipping costs. Lead time for samples is typically 10‑12 working days.
