4 Drawer Bathroom Cabinet – Technical Overview

This unit provides four vertically stacked drawers intended for storage of toiletries, linens, and cleaning supplies in commercial or institutional bathrooms. The design emphasizes dimensional stability, moisture resistance, and ease of maintenance.

Key Dimensional Characteristics

Overall height is 920 mm, width 450 mm, and depth 350 mm, based on a standard 600 mm vanity module. Each drawer opening measures 80 mm high, 410 mm wide, and 300 mm deep, allowing accommodation of standard 100 mm‑high toiletries containers.

The cabinet carcass is constructed from 18 mm thick moisture‑resistant medium‑density fiberboard (MR‑MDF) with a density of 650 kg/m³, providing a shear strength of approximately 2.5 MPa in the plane of the board.

Dimensions and Load Capacity

Material Construction

The carcass uses MR‑MDF with a melamine‑faced overlay that provides a water‑vapor transmission rate (WVTR) below 0.5 g/(m²·day) at 23 °C/50 % RH, reducing swelling in humid environments. Edge sealing is applied with 1 mm PVC edge band, offering a peel resistance of ≥1.2 N/mm.

Drawer sides are fabricated from 12 mm thick MR‑MDF, reinforced with a 0.8 mm steel stretcher rail on the underside to limit deflection under load to less than 0.5 mm when loaded to 15 kg.

• Overlay options: white melamine, light grey melamine, or natural wood veneer (0.6 mm thick).
• Hardware: concealed full‑extension soft‑close slides rated for 30,000 cycles.
• Handle: zinc‑alloy pull, 120 mm center‑to‑center, with a torque rating of 2.0 Nm.

Load Bearing and Hardware Specifications

The soft‑close slide mechanism incorporates a hydraulic damper that provides a closing speed of 0.2 m/s and a impact force below 5 N, reducing wear on the drawer front. Slide travel is 340 mm, allowing full access to the drawer interior.

Each drawer is secured to the carcass with four 4 mm × 12 mm wood screws, providing a withdrawal resistance of approximately 1.8 kN per fastener.

Typical Applications in Commercial and Institutional Bathrooms

In hotels, the cabinet is installed beneath wall‑mounted vanities to provide guest storage for personal items, reducing clutter on countertops. The moisture‑resistant finish withstands frequent cleaning with alkaline detergents (pH 9‑11) without degradation of the overlay.

In healthcare facilities, the unit stores sterile supplies and disposable garments; the smooth, non‑porous surface facilitates disinfection with 70 % isopropyl alcohol, meeting ISO 14644‑1 Class 8 cleanroom adjunct requirements.

Educational institutions specify the cabinet in dormitory bathrooms where durability against impact and frequent use is essential; the steel‑reinforced drawer sides resist permanent deformation under repeated 10 kg loads.

Quality Control and Testing

Before shipment, each cabinet undergoes a 24‑hour humidity soak test at 40 °C/90 % RH, after which dimensional change is measured; acceptable variation is ≤0.3 % in height and width.

Slide cycle testing is performed on a randomized sample of 10 % of production, executing 30,000 open‑close cycles at a rate of 10 cycles/min; no increase in slide resistance beyond 15 % of initial value is permitted.

Finish adhesion is verified via cross‑hatch tape test (ASTM D3359) requiring a rating of 5B (no delamination) after exposure to 40 °C/80 % RH for 168 hours.

Customization Options

Dimensional adjustments are available in 10 mm increments for height, width, and depth to accommodate non‑standard vanity modules. Drawer count can be varied from two to six while preserving the same load‑per‑drawer rating.

• Alternative overlay materials: high‑pressure laminate (HPL) with a wear resistance of 150 cycles (Taber Abrader) or antimicrobial powder coating.
• Slide upgrades: ball‑bearing slides with a load capacity of 25 kg per drawer and a rated life of 50,000 cycles.
• Handle styles: recessed pull, chrome‑plated bar, or touch‑latch mechanism.
• Locking options: cam lock or electronic RFID lock, each rated for 20,000 actuation cycles.

Frequently Asked Questions

• Q: Can the cabinet dimensions be customized to match a specific vanity width? A: Yes, width, height, and depth can be adjusted in 10 mm increments; provide the rough opening dimensions for a quotation.
• Q: What information is required before a quote is issued? A: Required inputs include overall dimensions, desired overlay material, slide type, handle style, and any locking or electronic accessories.
• Q: Which materials are available for the carcass and overlay? A: Standard carcass is MR‑MDF; overlay options are melamine, HPL, veneer, or antimicrobial powder coating.
• Q: How is quality inspected before shipping? A: Each unit receives humidity soak, slide cycle, and adhesion tests as described in the Quality Control section.
• Q: What packaging methods are available for export shipments? A: Units are packed in 5‑mm corrugated cartons with corner protectors and stretch‑film wrapping; palletization is available upon request.
