Single Sink Bathroom Vanity with Integrated Top – Factory Specifications

A single sink bathroom vanity with an integrated top combines the cabinet basin and countertop into a single manufactured unit, reducing on‑site assembly steps.

This configuration is commonly specified for hotel guest rooms, assisted‑living facilities, and high‑traction commercial restrooms where installation speed and joint integrity are critical.

The cabinet carcass is typically constructed from 18 mm moisture‑resistant medium density fiberboard (MDF) with a PVC edge band, providing a swelling resistance of less than 0.2 % after 24 h immersion.

Drawer boxes use dovetail joints reinforced with ½‑inch steel cam locks, achieving a shear strength of approximately 1.5 kN per joint.

The integrated top is fabricated from either 20 mm quartz composite or 12 mm solid surface acrylic, both offering a non‑porous surface with a water absorption rate below 0.04 %.

Standard widths range from 600 mm to 1200 mm in 100 mm increments, with a fixed depth of 460 mm and a height of 820 mm including the top.

Tolerances are held to ±2 mm on overall dimensions and ±0.5 mm on cut‑out locations for faucet and drain fixtures.

Customization Options

Customization is limited to geometric modifications and finish selections that do not alter structural load paths.

All options are evaluated against the same moisture‑resistance and mechanical standards as the base product.

Faucet drilling: single‑hole, widespread (8‑inch centers), or wall‑mounted configurations
Drain cutout: standard 45 mm offset, rear‑center, or side‑positioned
Edge profile: eased, bullnose, or beveled (radius 3 mm to 8 mm)
Hardware finish: brushed nickel, chrome, matte black, or PVD gold
Interior accessories: soft‑close drawer glides, adjustable shelving, or integrated LED lighting strips (12 V DC)

Quality Control and Testing

Each unit undergoes a dimensional inspection using a coordinate measuring machine (CMM) with a repeatability of ±0.02 mm.

Surface finish is assessed with a gloss meter; quartz tops must maintain 55–70 GU at 60° incidence, solid surface 40–55 GU.

Load testing applies a 150 kg static load to the countertop for 24 h; permissible deflection is limited to 0.3 mm.

Applications and Rationale

In hospitality environments, the reduced number of seams between cabinet and top minimizes water ingress points, lowering the risk of swelling and mold growth.

For assisted‑living units, the integrated top eliminates a sharp overhang that could impede wheelchair access, complying with ADA clearance requirements of 900 mm knee space.

The monolithic construction also speeds up renovation cycles, as installation time drops from an average of 4 hours per unit (separate cabinet and top) to 1.5 hours.

Frequently Asked Questions

Q: Can the vanity dimensions be customized beyond the standard width increments?
A: Yes. Width adjustments in 10 mm steps are possible, subject to a minimum panel width of 500 mm to maintain structural integrity. For details, please contact us.

Q: What information is required to obtain a quotation?
A: Required data include desired width, top material, faucet drilling pattern, edge profile, hardware finish, and any accessory options (e.g., LED lighting). Providing a rough sketch or CAD file speeds up the review.

Q: Which materials are available for the integrated top, and what are their key performance differences?
A: The factory offers 20 mm quartz composite (high scratch resistance, gloss 55‑70 GU) and 12 mm solid surface acrylic (seamless repairability, gloss 40‑55 GU). Both meet the same water‑absorption (<0.04 %) and chemical‑resistance standards.

Q: How are export shipments protected against damage?
A: Units are packed in double‑wall corrugated cartons with corner protectors, then placed on pallets and stretch‑wrapped. Each carton includes a moisture‑barrier liner and is labeled with handling instructions.
