OEM Grey Freestanding Bathroom Cabinets

Freestanding bathroom cabinets are self‑supporting units that do not require wall anchoring, making them suitable for retrofit projects where substrate condition is uncertain. In OEM supply, the cabinets are delivered as finished sub‑assemblies that integrate directly into vanity systems or standalone installations. The grey finish is achieved through a pigmented coating system that provides consistent color across large production runs.

Material Composition

The cabinet carcass is typically constructed from 18 mm exterior‑grade plywood with a core density of 600 kg/m³, selected for its resistance to swelling in humid environments. Alternative core options include 16 mm moisture‑resistant MDF (MR‑MDF) with a formaldehyde emission class E0, or marine‑grade plywood for projects requiring extra durability. All panels are edge‑banded with 0.5 mm PVC to prevent moisture ingress at cut edges.

• Exterior‑grade plywood, 18 mm, density 600 kg/m³
• Moisture‑resistant MDF, 16 mm, E0 formaldehyde
• Marine‑grade plywood, 12 mm, for wet zones

Structural Design

The cabinets employ a frameless, full‑access design with concealed cam‑lock fasteners that provide a tensile shear strength of approximately 1.2 kN per joint, sufficient for dynamic loads from daily use. Internal shelves are supported by 3 mm steel brackets screwed into pre‑drilled inserts, allowing a uniformly distributed load of up to 25 kg per shelf without deflection exceeding 0.5 mm. Back panels are 3 mm hardboard glued and stapled to increase racking resistance.

Dimensional Flexibility

Standard width modules range from 400 mm to 800 mm in 100 mm increments, with a fixed height of 820 mm to accommodate common countertop thicknesses. Depth is typically 460 mm, but can be adjusted between 380 mm and 520 mm to suit varying bathroom layouts. All dimensions are held to a tolerance of ±0.5 mm to ensure repeatable fit across production batches.

Surface Finish & Moisture Resistance

The grey finish is applied via a two‑stage UV‑cured polyurethane coating system, delivering a dry film thickness of 60 µm and a surface hardness of 2H on the pencil scale. Laboratory testing shows water absorption of less than 0.5 % after 24 hours immersion, meeting the requirements for Class 1 moisture resistance in bathroom environments. The coating maintains colour stability with a ΔE<2 after 200 hours of UV exposure per ISO 11507.

Hardware Integration

Concealed soft‑close hinges are rated for 30 000 cycles and provide a closing torque of 0.2 Nm, ensuring quiet operation even under frequent use. Drawer options utilize full‑extension ball‑bearing slides with a dynamic load capacity of 25 kg and a lateral deflection limit of 0.2 mm under full load. All hardware is pre‑installed in the OEM package to reduce on‑site assembly time.

Quality Assurance

Each batch undergoes dimensional verification using a coordinate measuring machine (CMM) with a repeatability of ±0.1 mm, followed by a visual inspection for coating defects under 500 lux illumination. Mechanical tests include a static load test of 150 kg on the cabinet base and a humidity cycling test (30 %‑90 % RH, 25 °C) for 10 cycles to confirm no delamination. Documentation of test results is available upon request.

Packaging & Logistics

Cabinets are wrapped in 150 µm polyethylene film, then placed in double‑wall corrugated cartons with 10 mm edge protectors on all corners. Palletized loads are secured with PET straps and stretch‑wrapped to prevent movement during transit. Standard pallet configuration holds up to 20 units, with a gross weight of approximately 420 kg per pallet.

• Individual carton with foam corner protectors
• Bulk pallet with interleaving sheets
• Custom crating for overseas shipments (ISPM‑15 compliant)

Frequently Asked Questions

Can the cabinet dimensions be customized to match specific vanity tops?

Yes. Width, height and depth can be adjusted within the ranges shown in the dimensional table, subject to tooling constraints and minimum order quantities.

What information is required before a quotation can be issued?

We need the required overall dimensions, panel material preference, finish colour code (RAL or NCS), hardware specifications (hinge type, slide load), and any special certification needs (e.g., FSC, CARB2).

Which material options are available for high‑humidity environments?

Exterior‑grade plywood, marine‑grade plywood, and moisture‑resistant MDF (E0) are all available; the selection depends on the expected humidity level and budget.

How is quality inspected before shipment?

Each unit receives a dimensional check (±0.5 mm tolerance), coating adhesion test (cross‑hatch per ASTM D3359), and functional test of hinges and slides. A final audit report is included with the shipping documents.

What packaging methods are available for export?

Standard export packaging includes polyethylene film, double‑wall cartons with corner protectors, and PET‑strapped pallets. Optional wooden crates compliant with ISPM‑15 can be provided for high‑value or fragile shipments.

What is the typical production lead time?

Lead time varies from 3 to 5 weeks after approval of drawings, depending on material availability and order size. Expedited schedules are possible for stocked panel grades.
