OEM Bathroom Vanity Cabinet – Bare Unit

An OEM bathroom vanity cabinet supplied as a bare unit includes the carcass, doors, drawers, and hardware, but excludes countertops, sinks, faucets, and backsplashes. This configuration allows integrators to match the cabinet to project‑specific surfaces and plumbing layouts while maintaining control over overall dimensions and installation sequencing.

Construction relies on 18 mm moisture‑resistant medium density fibreboard (MR‑MDF) with a nominal density of 680 kg/m³ and a thickness tolerance of ±0.3 mm. The panels are bonded with a urea‑formaldehyde resin that meets EN 312 class P2 for interior humid environments, providing a 24‑hour water absorption rate below 8 % by weight.

Joinery methods combine cam‑lock fasteners for panel‑to‑panel connections and reinforced dowels for door hinges, yielding a static load capacity of 150 kg per cabinet when evenly distributed. All metal components are zinc‑plated to resist corrosion in typical bathroom humidity cycles (30‑80 % RH, 5‑40 °C).

Dimensional tolerances are held to ±2 mm for overall width, height, and depth, and ±1 mm for door reveal gaps, ensuring seamless alignment with adjacent fixtures and countertop overhangs. These limits are verified on a coordinate measuring machine (CMM) during first‑article inspection.

Surface finish options include melamine‑impregnated paper (0.2 mm thickness, Taber abrasion resistance >300 cycles), high‑pressure laminate (HPL, 0.7 mm, >600 cycles), and natural wood veneer (0.6 mm, sealed with UV‑cured polyurethane). Each finish is supplied with a matching PVC edge band of 0.8 mm thickness, applied via hot‑melt adhesive for edge‑seal integrity.

Customization choices encompass door styles (flat‑panel, shaker, raised‑panel), hinge types (concealed European, butt, soft‑close), drawer slide mechanisms (ball‑bearing, undermount, soft‑close), and internal accessories such as adjustable shelves, pull‑out trays, and towel bars. All options are defined by parametric CAD models that update cut‑lists and hardware schedules automatically.

Applications benefit from the cabinet’s role as a modular substrate that integrates with quartz, solid surface, or tile countertops via silicone adhesive or mechanical brackets. Engineers select this bare‑unit approach to reduce on‑site fabrication, minimize waste, and accommodate varying rough‑in plumbing dimensions without redesigning the cabinet carcass.

Quality control philosophy follows a three‑stage protocol: incoming material verification (density, moisture content, thickness), in‑process checks (cam‑lock torque, hinge alignment, edge‑band adhesion), and final audit (dimensional CMM scan, finish visual grade per ASTM D4236, functional load test). Results are recorded in a traceable batch record retained for 24 months.

Packaging utilizes flat‑pack cartons with 6 mm corrugated walls, corner protectors of expanded polystyrene, and stretch‑film wrapping to prevent moisture ingress. Each carton includes a detailed assembly drawing, hardware bag labelled by part number, and a desiccant packet to maintain relative humidity below 50 % during transit.

Typical lead time for first article approval is 3‑4 weeks after receipt of approved drawings and material specifications, followed by production lead times of 2‑3 weeks for orders exceeding 50 units. Minimum order quantities start at 20 units for standard configurations, with lower volumes available upon request for prototype runs.
