Free Standing Bathroom Cabinet Under Sink

This cabinet is designed to sit on the floor beneath a wall‑mounted sink, providing storage without requiring wall anchoring. The unit relies on a rigid frame and adjustable leveling feet to accommodate uneven flooring.

Structural Design

The cabinet frame is constructed from 1.2 mm cold‑rolled steel, formed into a rectangular chassis with reinforced corners. Two vertical uprights support a horizontal top plate that bears the sink load, while a bottom shelf provides additional storage. Leveling feet with 30 mm travel compensate for floor slope up to 5 mm.

Materials and Finishes

Primary structure uses SPCC steel with a zinc‑phosphate pretreatment followed by a powder‑coat finish. Available coating thicknesses are 60 µm (standard) or 120 µm (high‑corrosion‑resistance). Interior shelves are 18 mm melamine‑faced particle board, edged with PVC banding.

Typical Dimensions

Installation Considerations

The cabinet is positioned directly on the finished floor. Leveling feet are turned until the top plate is within 2 mm of horizontal, verified with a spirit anchor. No wall brackets are required, but a clearance of at least 50 mm behind the unit is recommended for plumbing access.

Electrical outlets, if needed for accessories, should be routed through the rear panel cut‑out, which is supplied as a 100 mm × 50 mm knockout.

Applications in Commercial Settings

Free‑standing under‑sink cabinets are commonly installed in hotel guest rooms, healthcare facility washrooms, and high‑traffic public restrooms where floor‑mounted storage simplifies renovation and reduces reliance on structural wall capacity.

• Hotel suites – provides toiletries storage while maintaining a clean aesthetic.
• Clinical environments – allows easy cleaning of the floor beneath the unit.
• Public restrooms – reduces installation time compared to wall‑hung cabinets.

Quality Control

Each unit undergoes a dimensional inspection using a CMM with ±0.1 mm tolerance on critical interfaces. Powder‑coat adhesion is tested per ASTM D3359, requiring a minimum rating of 4B. Load testing applies a static 150 kg force to the top plate for 10 minutes; deflection must remain under 2 mm.

Customization Options

Dimensions can be adjusted in 50 mm increments for height and width, and 25 mm increments for depth, within the frame’s structural limits. Finish colors are available from the RAL classic palette; custom colors require a minimum order quantity of 50 units. Interior accessories such as pull‑out bins, towel rails, or integrated LED lighting can be added as modular kits.
