Custom bathroom vanities give hotel owners the chance to match the property's design language exactly — right color, right dimensions, right sink configuration — without compromise. But specifying a custom vanity for commercial use is different from residential. You need to think about substrate moisture resistance, edge profile cleanability, faucet hole positioning for ADA compliance, and minimum order quantities that won't blow the budget. This guide covers every specification point a hotel owner or project manager needs to hand their supplier. At Guangdong Wiselink Ltd., we fabricate over 30,000 custom vanity units annually, and these are the specs that separate a 15-year vanity from a 5-year vanity.
Custom vanities are usually custom because the standard sizes (36", 48", 60", 72") don't fit the layout. Here's what you need to specify:
Vanity width — measured wall to wall. For custom applications, widths from 24" to 96" are common. A 72" double-basin vanity should have minimum 30" of clear counter space between basins for toiletries.
Vanity depth — standard countertop depth is 22" from the wall. This accommodates a standard 19" deep cabinet with a 3" overhang. For ADA compliance, the countertop must be 34" max height at the front edge, and the sink depth must leave 27" of clear knee space underneath. ADA vanities are typically 27" deep minimum.
Countertop height — standard is 36" in commercial applications. Residential is 34". Specify 34" for ADA. If the property serves diverse demographics, just go with 34". It's a comfort height for shorter guests and still works for taller ones.
Toe kick — standard 4" height x 3" depth. Non-negotiable in commercial. It protects the cabinet face from mop damage.
Backsplash height — 4" standard. If the vanity backs up to a tiled wall, that's sufficient. For painted drywall, specify 6" minimum to protect the wall from water and toothpaste splatter.
Countertop overhang — 1" to 1.5" on the front and sides. Over 1.5" creates a leverage risk if someone sits on the counter. Zero overhang (flush with cabinet) is modern but doesn't protect the cabinet face from splashes.
Now, on edge profiles — this matters more in hotels than in homes, because cleaning speed matters. A square edge (standard) is a 90-degree edge, eased slightly (1/16" radius) to prevent chipping. Cleanest look, easy to wipe. Most popular for modern properties. Beveled edge adds visual interest with a 45-degree chamfer, but it creates a slight dirt trap at the junction with the cabinet face. Acceptable but not preferred for housekeeping. Bullnose (full radius, 1/2" to 3/4") is the traditional hotel look. Rounded edges are gentler if a guest bumps into them, but they collect dust and need two passes to wipe. Housekeeping hates them. Ogee or decorative profiles? Avoid in commercial. Multiple curves and steps create cleaning nightmares. Our recommendation for most hotel projects: square edge, eased, matte finish. It looks clean, it stays clean, and maintenance can repair it easily if damaged.
You have three sink options for a custom vanity. Here's how they compare for hotel use:
For our Wiselink custom vanities, about 70% of hotel orders now specify integrated sinks. The remaining 30% are mostly undermount for properties that want natural stone.
The cabinet under the countertop matters as much as the countertop itself. Here's the deal:
Cabinet box material should be 3/4" plywood (interior-grade or better) minimum for commercial use. Don't accept particleboard or MDF for vanity cabinets in a bathroom environment — moisture from daily use will swell them. Plywood expands less than 1% at 90% relative humidity vs MDF at 2-3%. Cabinet face: solid wood or plywood with veneer. Thermofoil (PVC-wrapped MDF) is cost-effective but delaminates in high-humidity bathrooms within 3-5 years. We've seen it happen more times than I can count.
Drawer construction: dovetail joinery on plywood drawers is the commercial standard. Stapled or nailed drawers fail. Full-extension, soft-close undermount drawer slides (Accuride or Blum) are mandatory. Side-mount slides in a hotel environment? Don't even think about it. Door hinges: 5-knife overlay hinges with soft-close, stainless steel only. Zinc or nickel-plated hinges corrode in bathroom humidity. Blum 120-degree or comparable is the standard.
Waterproofing: the cabinet base should be lined with PVC sheet or sealed with waterproof epoxy. A leak from the sink or supply line will destroy an unsealed cabinet in hours. Sealed cabinets give maintenance time to find and fix the leak. Finish: conversion varnish (pre-catalyzed or post-catalyzed lacquer) is the most durable option for commercial bathroom cabinets. It resists humidity, cleaning chemicals, and impact. Don't accept standard furniture lacquer in a bathroom.
Cutout specs for faucets and accessories. If you're providing the countertop pre-drilled (recommended), here's what to spec: Faucet holes — 4-inch centerset is standard for single-hole faucets. 8-inch widespread for two-handle designs. Specify the faucet model before the countertop is fabricated — different faucets have different shank diameters. A standard faucet hole is 1-3/8" diameter. Soap dispenser hole — 1" diameter, typically placed 2" from the backsplash and 6" from the left basin edge. It's cheaper to drill and plug an unused hole than to drill later. Access panel: if the vanity has an electrical outlet or shutoff valve behind it, specify a removable access panel (magnetic catch, no visible hardware).
For custom colors, provide a physical sample (paint chip, tile, or Pantone reference). Wiselink matches within Delta E of 1.0 on solid surface. Lead time for custom color development: 2-3 weeks and $200-$500 for the process. Once approved, the color is archived for reorder.
Minimum order quantities: standard colors (10-15 stock colors) — 25 units per design. Custom colors — 100 units per design. Custom size (non-standard width) — 50 units. Edge profile change only — 30 units. These are typical across the industry. Some suppliers offer lower MOQs at a per-unit premium (typically 15-25% higher). Full container orders (200-300 vanity units depending on size) get the best pricing — roughly 20-30% below LCL pricing.
Q: Can I get a custom vanity made with natural stone instead of solid surface?
A: Yes. Natural stone custom vanities are common. The trade-offs: stone is heavier (80-120 lbs for a 48" countertop vs 35-45 lbs for solid surface), requires annual sealing, and can't have an integrated sink — it must be undermount with a sealed joint. Lead time is similar (4-7 weeks for stone fabrication). Cost is typically 30-60% higher for comparable quality.
Q: What's the typical lead time for a fully custom vanity (cabinet + solid surface countertop)?
A: From approved shop drawings and color sample sign-off: 6-9 weeks for production, plus 3-5 weeks for ocean freight to US West Coast. Air freight is possible (1 week transit) but adds $400-$800 per unit depending on size. Plan for 10-14 weeks total for most projects.
Q: Do I need shop drawings for every vanity?
A: Yes, for any custom size or configuration. The shop drawing shows the exact dimensions, cutout positions, edge profiles, and cabinet construction. It's the contract between you and the fabricator. Approve it carefully — changes after production starts cost both time and money.
Q: What if the vanity dimensions are wrong after installation?
A: Field modification of a solid surface countertop is possible for small adjustments (up to 1" trim on a non-sink end) but not recommended for the sink area. Measure twice, order once. We suggest ordering vanities after framing is complete and drywall is hung, not before. Actual dimensions vary from architectural drawings.
Q: How do I handle the faucet installation? Front-mount or deck-mount?
A: Deck-mount is standard (faucet through the countertop). Wall-mount faucets are trending in luxury properties because they make the countertop surface easier to clean. If specifying wall-mount, tell your countertop supplier — they'll leave out the faucet holes and you'll need to coordinate with the plumber for supply lines in the wall.
