OEM Double Vanity Master Bathroom Unit

Overview

The unit combines two symmetrical basins with integrated storage cabinets into a single prefabricated assembly, reducing on‑site labor for master‑bathroom installations. Each basin is positioned 600 mm apart center‑to‑center, providing adequate clearance for simultaneous use. The overall footprint typically ranges from 1200 mm to 1800 mm in width, 560 mm in depth, and 850 mm in height, adjustable to project requirements.

Core Construction and Materials

Cabinet boxes are built from 18 mm marine‑grade plywood with a density of 600 kg/m³, offering a modulus of elasticity around 4.5 GPa. Edge sealing uses PVC edge banding 0.5 mm thick to limit moisture ingress. Countertop options include 20 mm quartz (water absorption <0.05 %), 12 mm solid surface (flexural strength 55 MPa), or 18 mm granite, each bonded with a two‑part polyurethane adhesive rated for 2 MPa shear strength.

Dimensional Flexibility and Modularity

The system uses 100 mm modular panels that can be added or removed in increments to achieve custom widths without redesigning the structural frame. Tolerance on panel alignment is ±0.5 mm, ensuring tight joints when assembled. Height adjustment is accomplished via concealed steel brackets with 25 mm vertical travel, locked by set screws to maintain load path integrity.

Load‑Bearing and Structural Performance

Each countertop is designed to support a uniformly distributed load of 150 kg, corresponding to a maximum point load of 300 kg at the basin rim without exceeding L/200 deflection (where L is span). Wall mounting employs four M10 anchor bolts per side, embedded into studs with a minimum embedment depth of 60 mm, providing a shear capacity of 8 kN per anchor per AISC standards.

Surface Finish Options

Finishes range from high‑pressure laminate (HPL) with a Taber abrasion rating of 300 cycles to 0.5 mm wear, to UV‑cured acrylic lacquer offering a gloss level of 85 GU and a pencil hardness of 2H. Veneer selections are available in 0.6 mm thick oak or walnut, sealed with a two‑component polyurethane topcoat achieving a wet‑film thickness of 80 µm and a cross‑hatch adhesion rating of 5B per ASTM D3359.

Plumbing Integration

Basins feature pre‑drilled 35 mm faucet holes on 150 mm centers, with an optional 50 mm offset for widespread fixtures. Drain outlets are positioned 100 mm from the rear wall, accommodating standard P‑traps with a minimum 50 mm clearance. Supply lines are routed through 22 mm diameter chase holes located 30 mm above the finished floor, allowing for 1/2‑inch copper or PEX tubing without notching the cabinet.

Customization Workflow

Customers submit CAD files or hand sketches indicating desired width, basin configuration, and hardware preferences. Engineers review for structural feasibility, generate a detailed shop drawing, and confirm material selections. A prototype panel is produced for fit‑check, followed by final production once sign‑off is received, typically within 10‑15 business days.

Quality Assurance and Testing

Each unit undergoes a five‑point inspection: dimensional verification (±1 mm), finish adhesion (cross‑hatch test), load cycle (10 000 repetitions at 50 kg), moisture resistance (48 h immersion at 20 °C, weight gain <0.2 %), and hardware operation (soft‑close hinge torque 0.2 Nm ±10 %). Test results are recorded and traceable via serial number.

Packaging and Logistics

Units are shipped flat‑packed in triple‑wall corrugated crates measuring 1300 mm × 620 mm × 260 mm, with a gross weight of 45 kg per module. Corner protectors and edge foam safeguard panels, while a moisture‑barrier liner prevents condensation during transit. Assembly instructions and hardware kits are included in a sealed pouch attached to the interior.

Typical Applications

Master bathrooms benefit from the double‑vanity layout because it provides two independent washing stations, reducing morning congestion. The integrated storage addresses the high demand for toiletries and linens in master suites, while the moisture‑resistant substrate ensures longevity in environments with relative humidity frequently exceeding 70 %.

Frequently Asked Questions

• Can dimensions be customized? Yes, width can be adjusted in 100 mm increments; height adjustment is available via concealed brackets with 25 mm travel.
• What information is required before quotation? Required inputs include overall width, basin configuration, preferred countertop material, hardware finish, and any special plumbing rough‑in locations.
• What materials are available for the cabinet body? Standard is 18 mm marine‑grade plywood; alternatives such as moisture‑resistant MDF or aluminum extrusions are offered upon request.
• How is quality inspected? Each unit undergoes dimensional verification, finish adhesion testing, load cycling, moisture resistance testing, and hardware operation checks before packaging.
• What packaging methods are available? Units ship flat‑packed in triple‑wall corrugated crates with corner protectors and a moisture‑barrier liner; optional fully‑assembled crating is available for short‑haul deliveries.
• How are export shipments protected? Crates are lined with polyethylene film, sealed with strapping, and marked with handling instructions; palletized loads use corner boards and stretch wrap.
• What is the typical production lead time? Standard lead time is 10‑15 business days after drawing approval; expedited options can reduce this to 5‑7 days for stocked materials.
• How are samples arranged? Sample panels (100 mm × 100 mm) of selected materials and finishes can be shipped via courier upon request, with costs credited against the final order.
