OEM Wall Hung Bathroom Cabinet with Sink

Overview

A wall‑hung bathroom cabinet integrates a basin and storage unit into a single assembly that is fixed to the structural wall via concealed brackets. The design eliminates floor‑standing legs, simplifying cleaning and allowing flexible layout planning in commercial restrooms.

Technical Specifications

Materials & Finish

The cabinet carcass is constructed from moisture‑resistant medium‑density fibreboard (MR‑MDF) with a density of 650 kg/m³, providing dimensional stability in humid environments. Edge sealing uses PVC‑free hot‑melt adhesive to prevent water ingress.

The sink basin is formed from 304 stainless steel, 1.2 mm thick, polished to a satin finish (Ra ≤ 0.8 µm). Alternative basin materials include vitreous china or solid surface, selectable per project hygiene requirements.

Surface finishes for the cabinet body are available in high‑pressure laminate (HPL) with abrasion resistance ≥ 350 cycles (Taber), melamine foil with UV‑stable pigmentation, or powder‑coated aluminum extrusion for a metallic appearance.

Design & Customization Options

Dimensional adjustments are performed in 10 mm increments to match rough‑in plumbing layouts. The cabinet can be supplied with pre‑drilled faucet holes (standard 35 mm diameter) or blank plates for on‑site drilling.

Internal organization includes adjustable shelving (spacing 25 mm increments) and optional pull‑out trays with full‑extension slides rated for 30 kg dynamic load. Door hinges are concealed soft‑close mechanisms rated for 50 000 cycles.

• Left‑hand or right‑hand door swing
• Integrated LED lighting strip (12 V, 5 W/m) with motion sensor
• Anti‑microbial coating on interior surfaces (silver‑ion based, 99.9 % reduction per ISO 22196)
• Vandal‑resistant lock cylinder (Euro profile)

Structural Performance

Load testing follows ANSI/BIFMA X5.1‑2021 criteria: a uniformly distributed load of 150 kg applied to the sink rim results in a maximum deflection of 1.2 mm at the cabinet front edge, well within the L/200 serviceability limit for wall‑mounted fixtures.

Wall anchorage requires four M8 expansion bolts with a minimum embedment depth of 60 mm into concrete or solid masonry, providing a shear capacity of 2.5 kN per bolt. For stud‑wall installations, steel brackets are supplied to transfer load to at least two vertical studs.

Finite‑element analysis indicates that the first natural frequency of the assembled unit exceeds 18 Hz, reducing risk of resonance excitation from typical building services.

Applications in Commercial Projects

In hotel guest bathrooms, the wall‑hung configuration frees floor space for wheelchair turning circles, supporting ADA compliance. The integrated sink reduces joint lines, simplifying silicone maintenance and lowering the risk of mold growth.

Healthcare facilities benefit from the seamless stainless‑steel basin, which withstands frequent disinfection with chlorine‑based agents without corrosion. The cabinet’s smooth surfaces enable rapid wiping between patient visits.

Office complexes specify the unit for high‑traffic restrooms where cleaning cycles occur every 30 minutes; the HPL surface resists staining from common restroom chemicals and retains colour stability under fluorescent lighting.

Quality Assurance & Testing

Every production lot undergoes dimensional inspection using a coordinate‑measuring machine (CMM) with a tolerance of ±0.5 mm on critical mounting holes. Finish adhesion is measured via cross‑hatch tape test (ASTM D3359) requiring a minimum rating of 4B.

Salt‑spray exposure (ASTM B117) is conducted on stainless‑steel basins for 500 hours; acceptable results show no red rust and a maximum mass loss of 0.02 g/m². For laminate surfaces, UV‑accelerated weathering (ASTM G154) verifies colour ΔE < 3 after 300 hours.

Functional testing includes 10 000 opening/closing cycles for doors and slides, with performance logged to ensure force remains below 15 N throughout the test.

Packaging & Logistics

Units are shipped flat‑packed in triple‑wall corrugated cartons with internal corner protectors made of recycled polyethylene foam. Each carton includes a clear assembly instruction sheet, torque‑specified fastener kit, and a QR code linking to a 3‑D installation guide.

Carton dimensions are optimized for palletization: 1200 mm × 800 mm × 200 mm (L × W × H), allowing 24 units per standard Euro pallet. Total gross weight per unit averages 22 kg, facilitating manual handling while staying within ergonomic limits.

For overseas shipments, cartons are placed in heat‑treated wooden crates conforming to ISPM 15, with desiccant packs to maintain relative humidity below 50 % during transit.

FAQ

• Can dimensions be customized? Yes, width, height, and depth can be adjusted in 10 mm increments; sink basin depth and faucet hole locations are also modifiable.
• What information is required before quotation? Provide rough‑in measurements, desired material finishes, any required accessories (e.g., lighting, locks), and the intended installation substrate (concrete, stud wall, etc.).
• What materials are available for the cabinet body? Standard is 18 mm MR‑MDF with HPL or melamine finish; optional upgrades include marine plywood, stainless‑steel frame, or solid‑surface panels.
• How is quality inspected? Each lot receives CMM dimensional checks, finish adhesion tape tests, salt‑spray or UV exposure depending on material, and functional cycle testing of moving parts.
• What packaging methods are available? Flat‑pack in corrugated cartons with foam corners; optional wooden crate packing for export; palletized for bulk shipment.
• How are export shipments protected? Cartons are placed in ISPM 15‑compliant crates, sealed with polyethylene wrap, and include desiccant to control humidity.
• What is the typical production lead time? Standard configurations ship within 3‑4 weeks after receipt of approved drawings; custom finishes or special hardware may add 1‑2 weeks.
• How are samples arranged? Sample units can be supplied upon request; shipping costs are borne by the requester, and sample fees are credited against a subsequent order.
