Bathroom Vanities — Frequently Asked Questions
Questions about sourcing custom bathroom vanities, mirrors, and related fixtures.
What materials work best for bathroom vanity cabinets?
Marine-grade plywood and solid wood with proper sealing are the best choices for humid bathroom environments. MDF is acceptable if fully sealed with lacquer or PVC edge banding, but exposed MDF edges will swell with moisture. Particle board should be avoided in bathrooms unless it is high-moisture-resistant (HMR) grade. Many factories use aluminum-framed cabinets for wet areas, which completely eliminates moisture concerns.
Can I order vanities with countertops and sinks included?
Yes, many factories offer complete vanity packages including the cabinet, countertop, undermount or vessel sink, and even the faucet. Marble, quartz, sintered stone, and ceramic countertops are all available. Shipping complete units requires extra care in packaging to protect stone edges and plumbing cutouts. Confirm whether the sink cutout is factory-made or if you need to arrange local stone fabrication.
What standard sizes are available for bathroom vanities?
Standard widths include 24, 30, 36, 48, 60, and 72 inches for the North American market. European and Australian markets typically use metric sizes like 600mm, 900mm, 1200mm, and 1500mm. Since most Chinese factories do custom manufacturing, non-standard sizes usually cost the same as standard ones. Always confirm the depth measurement, as wall-hung vanities are often shallower (45 to 50cm) than floor-standing units (55 to 60cm).
How do wall-hung vanities differ from floor-standing ones in terms of sourcing?
Wall-hung vanities require a concealed steel mounting bracket or French cleat system that must be anchored to wall studs or a solid wall. Confirm that the factory includes the mounting hardware and provides installation instructions with weight specifications. Wall-hung units must be built lighter, so material choices may differ. Ensure the wall at the installation site can support the loaded weight of the vanity.
What mirror and medicine cabinet options are available?
Factories offer frameless mirrors, framed mirrors, backlit LED mirrors, anti-fog mirrors, and full medicine cabinets with mirrored doors. LED mirrors are very popular and can include touch switches, dimmers, and color temperature adjustment. Shipping mirrors requires special crating to prevent breakage. Some buyers prefer to source mirrors locally to avoid transit damage and reduce shipping weight.
Are soft-close hinges and drawer slides standard on bathroom vanities?
Most mid-range and premium factories include soft-close hinges and full-extension drawer slides as standard features. Budget-tier vanities may use basic hinges without soft-close. Always confirm in your purchase order whether soft-close is included. Specify the brand if you have a preference — Blum and Hettich are widely available and add only a modest cost premium over generic options.
How should I handle plumbing compatibility between countries?
Plumbing fixture sizes and thread standards vary between regions. North America uses NPT threads, while most of the world uses BSP threads. Confirm drain hole size (typically 1.25 or 1.5 inches for vanity sinks) and supply line connection types with your factory. Some buyers specify that no plumbing fixtures be installed, preferring to fit locally sourced faucets and drains that match their regional standards.
What finishes resist moisture best for bathroom use?
Lacquer (polyurethane-based) provides excellent moisture resistance when applied with proper sealer coats. Thermofoil (PVC wrap) is also highly water-resistant since it creates a sealed surface. Melamine is moderately resistant but can fail at edge joints if water penetrates. Natural wood veneers need multiple coats of marine-grade clear coat. Avoid water-based paint finishes in high-humidity bathrooms as they may peel over time.
Can I get matching bathroom furniture sets (vanity, tall cabinet, mirror)?
Yes, ordering a coordinated set from one factory ensures perfect color and finish matching. Common bathroom furniture sets include a vanity unit, wall-hung mirror cabinet, tall storage tower, and sometimes a laundry hamper unit. Ordering as a set is also more cost-effective than sourcing pieces separately. Provide a complete bathroom layout with dimensions so the factory can propose a cohesive design.
What is the breakage rate for shipping stone countertops internationally?
With proper wooden crating and foam padding, breakage rates for stone countertops are typically 2 to 5 percent. Thinner tops (under 20mm) and pieces with narrow sections around sink cutouts are most vulnerable. Factories experienced in export will use A-frame crating for large slabs and individual boxing for vanity tops. Consider ordering a spare top for critical pieces, or plan to source countertops locally and ship only the cabinetry.
