China Round Bathroom Mirror Cabinet

Overview

A round bathroom mirror cabinet combines a sealed storage compartment with a polished reflective surface, suitable for environments where moisture exposure and cleaning frequency are high.

Design & Construction

The cabinet features a single‑piece formed rim that integrates the mirror backing, reducing joint lines and limiting water ingress points.

Internal shelving is adjustable in 25 mm increments, allowing reconfiguration for different toiletries without tools.

A concealed hinge mechanism provides a 110° opening angle while keeping the pivot hardware recessed to maintain a smooth exterior profile.

Material Options

Core structural elements are manufactured from cold‑rolled steel sheet with a minimum thickness of 0.8 mm, providing rigidity while keeping weight manageable.

Surface finishes are applied via electro‑galvanization followed by a powder‑coat layer, offering a salt‑spray resistance rating of at least 500 hours per ASTM B117.

Mirror glass is tempered to 4 mm thickness, compliant with EN 12150‑1 for impact resistance, and backed with a polyvinyl butyral (PVB) safety film.

Dimensional Specifications

Standard round diameters are available in 500 mm, 600 mm, and 700 mm, each with a consistent cabinet depth of 120 mm measured from the mirror face to the rear panel.

Custom diameters can be produced in 50 mm increments between 450 mm and 800 mm, subject to tooling constraints.

Internal clear height, measured from the bottom shelf to the underside of the mirror, is 90 mm, providing sufficient volume for typical toiletries.

Installation & Mounting

Mounting is achieved through four M6 stainless‑steel studs welded to the rear flange, spaced at 90° intervals to distribute load evenly.

Each stud engages with a corresponding wall anchor rated for a shear capacity of 2.5 kN, ensuring stability under dynamic loads such as door opening.

A leveling screw integrated into the bottom bracket allows ±3 mm vertical adjustment to compensate for uneven wall surfaces.

Applications in Commercial Facilities

In hospitality settings, the sealed interior protects amenities from humidity, reducing the frequency of replenishment cycles.

Healthcare facilities benefit from the smooth, non‑porous surfaces that facilitate disinfection with alcohol‑based agents without degradation of the coating.

Educational institutions specify the round geometry to eliminate sharp corners, aligning with safety guidelines for child‑accessible washrooms.

Quality Assurance Process

Each unit undergoes a dimensional check using a coordinate measuring machine (CMM) with a tolerance of ±0.5 mm on diameter and depth.

Mirror reflectivity is measured with a spectrophotometer, requiring a minimum of 85 % luminous reflectance across the visible spectrum.

Final assembly includes a 24‑hour condensation test at 40 °C and 90 % relative humidity to verify seal integrity.

Packaging & Logistics

Cabinets are packed in double‑wall corrugated cartons with internal polyethylene foam corners that absorb impact energies up to 15 J.

Each carton includes a desiccant packet to maintain internal relative humidity below 40 % during transit.

Pallet configuration follows ISO 6780 standards, allowing 24 units per pallet with a maximum stack height of 1.2 m.

Frequently Asked Questions

Regarding dimensional flexibility, diameters can be adjusted in 50 mm increments between 450 mm and 800 mm, with corresponding depth changes available upon request.

Concerning installation hardware, the standard M6 studs can be replaced with M8 bolts for higher load applications, subject to design verification.

About lead time, typical production cycles range from 18 to 22 working days for standard configurations, while custom finishes may add 5 to 7 days.
