An over‑toilet cabinet utilizes the vertical space above the fixture, providing storage without expanding the bathroom footprint. Typical units are designed to clear the toilet tank by at least 50 mm to allow lid operation and maintenance access.

Load capacity is determined by the mounting method and wall substrate; for stud‑mounted steel brackets a safe working load of 150 kg is common, while plasterboard anchors may limit this to 60 kg.

Design Considerations

Cabinet height usually ranges from 600 mm to 900 mm, matching standard toilet tank heights plus clearance. Depth is kept between 150 mm and 200 mm to avoid interfering with bathroom traffic.

Door swing direction is specified as left‑hand or right‑hand during ordering; recessed handles reduce protrusion to under 10 mm.

Material Options

• Cold‑rolled steel, 0.8 mm to 1.2 mm thickness, with zinc‑phosphate pretreatment.
• Extruded aluminum alloy 6063, 1.5 mm wall thickness, natural anodized finish.
• Moisture‑resistant MDF, 18 mm core, melamine laminate surface, edge‑sealed with PVC.

All materials are selected for resistance to humidity cycles typical in commercial restrooms (relative humidity 30 %–80 % at 20 °C–30 °C).

Construction Details

Panel joints are continuously welded (steel) or riveted (aluminum) and ground smooth; MDF panels use cam‑lock fasteners with concealed brackets.

Surface treatment options include powder coating (60 µm minimum thickness, UV‑stable), anodizing (15 µm for aluminum), or melamine overlay (0.2 mm).

Hinges are concealed, 180° rated, with soft‑close dampers rated for 50 000 cycles.

Installation

Mounting brackets are supplied with M8×50 mm bolts and nylon washers; brackets accommodate stud spacing of 400 mm or 600 mm.

Adjustable vertical slots allow ±15 mm positioning to compensate for uneven walls.

A silicone sealant bead of 3 mm diameter is recommended at the cabinet‑wall interface to prevent moisture ingress.

Typical Applications

In hotels and office buildings, over‑toilet cabinets provide guests with secure storage for personal items while maintaining a clean, uncluttered appearance.

Healthcare facilities benefit from the antimicrobial powder‑coat options, which support infection‑control protocols by allowing routine wipe‑down cleaning.

Technical Specifications

Quality Control

Dimensional inspection is performed on a coordinate measuring machine with tolerance ±0.5 mm on critical interfaces.

Coating adhesion is verified by ASTM D3359 cross‑hatch test; minimum rating 4B is required for powder‑coated units.

Each cabinet undergoes a 500‑cycle open/close test on the hinge assembly; any deviation beyond 2° in alignment results in rejection.
