48‑Inch Single‑Sink Bathroom Vanity

This unit provides a 48 mm wide countertop with a centered single‑sink cutout, designed for wall‑mounted or freestanding installation in commercial restrooms. The overall depth is 560 mm and the finished height is 820 mm from floor to top of countertop, accommodating standard ADA‑compliant knee clearance when paired with an appropriate support frame.

Materials and Construction

The countertop is available in three core materials: solid surface (acrylic‑based, 12 mm thickness), engineered quartz (93 % silica, 20 mm thickness), and vitreous china (glazed porcelain, 18 mm thickness). Each option is bonded to a moisture‑resistant MDF substrate (density 700 kg/m³) using a polyurethane adhesive that meets ASTM C1327 for water resistance.

Edges are sealed with a 2 mm PVC edge band that is heat‑welded to the substrate, providing a continuous barrier against water ingress. The supporting frame consists of 1.5 mm cold‑rolled steel brackets powder‑coated to a 60 µm thickness, rated for a static load of 250 kg per mounting point.

• Solid surface: non‑porous, renewable surface, repairable with sanding.
• Engineered quartz: high scratch resistance (Mohs 7), low water absorption (<0.05 %).
• Vitreous china: glazed surface, chemical resistance to cleaning agents, Class A fire rating.

Typical Applications

In hospitality environments, the 48 mm width allows two units to be placed side‑by‑side in a standard 2.4 m wide restroom wall, providing individual vanity stations while maintaining ADA clearance. The solid surface option supports frequent refinishing, which reduces lifecycle cost in high‑traffic hotel lobbies.

Healthcare facilities benefit from the non‑porous quartz or vitreous china surfaces that resist bacterial colonization and tolerate aggressive disinfectants (e.g., bleach, hydrogen peroxide) without surface degradation. The integrated backsplash prevents water spillage onto walls, simplifying cleaning protocols.

Educational institutions often select the wall‑mounted configuration with steel brackets because it facilitates rapid re‑configuration of restroom layouts during renovations, and the load rating of 250 kg per bracket accommodates heavy‑duty usage by students and staff.

Customization Options

• Countertop material: solid surface, engineered quartz, vitreous china, or laminate.
• Sink type: undermount, drop‑in, or vessel; single or double bowl configurations.
• Faucet drilling: pre‑drilled, blank, or custom hole patterns for sensor faucets.
• Backsplash: integrated, removable, or tiled; height adjustable from 0 to 150 mm.
• Finish: matte, semi‑gloss, or high‑gloss; color matching to RAL or Pantone standards.
• Support system: wall‑mounted steel brackets, freestanding base with adjustable leveling legs, or concealed steel frame.

Quality Assurance

Each countertop undergoes a 24‑hour immersion test at 40 °C to verify water absorption stays below the material‑specific threshold (solid surface <0.2 %, quartz <0.05 %). Edge seals are inspected with a 100 kPa air pressure test to confirm no leakage.

Steel brackets are subjected to a tensile load test to 1.5× the rated capacity (375 kg) and a corrosion resistance test per ASTM B117 (salt spray) for 500 hours, showing no red rust.

Final visual inspection checks for surface defects, color uniformity, and dimensional tolerance (±1 mm) before packaging.

Packaging and Shipping

• Primary protection: corrugated double‑wall carton with 10 mm edge protectors.
• Inner wrapping: low‑density polyethylene film to guard against moisture.
• Palletization: standard 1000 × 1200 mm pallets, max 20 units per pallet, secured with PET straps.
• Labeling: includes QR code linking to installation guide and material safety data sheet.
• Export compliance: ISPM‑15 treated wood pallets, optional fumigation certificate.
