Material names such as plywood, MDF, particleboard, laminate, lacquer or veneer do not describe a complete bathroom vanity. A buyer should record the substrate, surface system, edge treatment, joints, drilled openings, hardware and expected wet-use exposure for the exact model.
Separate substrate from surface
The structural board and decorative finish perform different roles. Ask for the actual panel construction and thickness by component, plus the surface layer, coating or veneer and its approved colour, grain and gloss range.
Inspect edges, joints and openings
Water-related failures often start at exposed edges, mitres, seams, fixing holes or plumbing cut-outs. The sample and inspection plan should identify how those locations are sealed and what workmanship is acceptable.
Match evidence to the selected model
A supplier statement, panel report or coating data can support the technical file, but it should not be presented as proof for an entire finished vanity unless the scope actually covers that model and construction. Confirm incorporated materials and production controls.
Buyer checklist
- Substrate type and thickness by component.
- Surface, colour, gloss and physical sample.
- Edge and joint construction.
- Hardware brand or performance requirement.
- Basin, countertop and plumbing cut-out treatment.
- Cleaning products and care limitations.
- Sample, first-article and production inspection criteria.
Approve the specification, not only the appearance
Photographs help with design selection, but repeat orders depend on a written bill of materials, finish reference, hardware schedule and measurable inspection criteria.
