OEM Small Corner Wall Hung Bathroom Cabinet

Design Constraints for Corner Installations

The cabinet footprint is defined by two perpendicular walls; the usable width on each wall is typically limited to 300‑450 mm to avoid interfering with adjacent fixtures. The mounting height is usually set between 800 mm and 900 mm from the finished floor to align with standard countertop levels, ensuring ergonomic access.

Material Selection and Thickness

For wet environments, the cabinet core is commonly constructed from 18 mm marine‑grade plywood or 16 mm moisture‑resistant MDF, both sealed with a PVC edge band. The door panels are often 6 mm tempered glass or 12 mm laminate‑covered particleboard, selected for impact resistance and ease of cleaning.

• Marine plywood – 18 mm thickness, 0.8 % swelling after 24 h water immersion
• Moisture‑resistant MDF – 16 mm thickness, formaldehyde class E1
• Tempered glass door – 6 mm thickness, surface compression ≥ 90 MPa
• Laminate finish – 0.2 mm PVC overlay, abrasion resistance 150 cycles (Taber)

Dimensional Parameters and Customization Ranges

Standard corner cabinets are offered in a modular grid that allows width adjustments in 50 mm increments, depth adjustments in 25 mm increments, and height adjustments in 25 mm increments. Custom sizes are engineered to match specific rough‑in dimensions while maintaining structural integrity.

Mounting Hardware and Load Capacity

The cabinet is secured using two concealed steel brackets rated for a shear load of 250 N each, fastened to wall studs with M6 × 50 mm wood screws. For drywall installations, toggle anchors with a pull‑out capacity of 400 N per anchor are specified. The total rated load, including dynamic forces from door opening, is limited to 600 N to ensure a safety factor of 3 under typical usage.

• Concealed brackets – cold‑rolled steel, zinc‑plated, 3 mm thickness
• Wall fasteners – M6 wood screws, torque 4 Nm
• Drywall anchors – zinc alloy toggle, rated 400 N pull‑out
• Adjustment range – ± 5 mm vertical, ± 3 mm lateral

Typical Applications in Commercial Bathrooms

In hotels, healthcare facilities, and high‑traffic public restrooms, corner wall‑hung cabinets free up floor area for wheelchair turning circles and reduce cleaning obstructions. The elevated position also protects stored items from splash water and facilitates easier access for users of varying stature, supporting universal design principles.

Quality Control and Testing

Each unit undergoes a three‑stage inspection: dimensional verification with a CMM (± 0.2 mm tolerance), adhesion testing of the PVC edge band (ASTM D3359, grade 5B), and a static load test where 600 N is applied for 5 minutes with no permanent deformation exceeding 0.5 mm. Finish durability is assessed via 500 cycle abrasion (Taber) and 24 hour humidity exposure at 95 % RH.

Frequently Asked Questions

Can dimensions be customized to match existing rough‑in?

Yes, width, depth, and height are adjustable in the increments listed; custom tooling is prepared after receipt of detailed drawings.

What information is required before quotation?

Rough‑in dimensions, wall material (stud, concrete, drywall), desired door finish, and any special hardware requirements.

What materials are available for the carcass?

Marine plywood, moisture‑resistant MDF, or optionally, stainless‑steel‑faced panels for corrosive environments.

How is quality inspected?

Dimensional CMM check, adhesion test, static load test, and finish abrasion/humidity tests as described.

What packaging methods are available?

Flat‑pack in double‑wall corrugated cartons with corner protectors, or fully assembled in wooden crates for high‑value projects.
