72 Inch Bathroom Vanity Double Sink With Top
72 Inch Bathroom Vanity Double Sink with Integrated Top
This unit measures 72 inches in width, providing a continuous countertop that accommodates two undermount sinks side‑by‑side. The overall depth is typically 22 inches, with a standard height of 34 inches to match ADA‑compliant vanity elevations when required.
Designed for environments where simultaneous use is common, the double‑sink layout reduces queuing time in high‑traffic bathrooms such as hotels, multifamily buildings, and upscale residential suites. The integrated top eliminates a seam between sinks, improving water resistance and simplifying cleaning.
By removing the joint, the monolithic top also increases structural rigidity, lowering deflection under load and reducing the risk of cracking over years of thermal cycling.
Key Design Features
The cabinet carcass utilizes ¾‑inch thick panels reinforced with a ½‑inch thick vertical stile at each end, providing a moment of inertia sufficient to resist sag under a 150 lb distributed load.
Each sink basin is formed with a 1‑inch radius interior corner and a ¼‑inch per foot slope toward the drain, ensuring rapid water evacuation and minimizing standing water.
Pre‑drilled faucet holes are spaced 8 inches on center, with optional side‑spray or soap‑dispenser provisions available upon request.
Material Composition
Substrate choices are selected based on moisture exposure and load requirements, with typical properties summarized below.
| Option | Typical Thickness | Water Absorption (24 h) | Weight (lb/ft²) |
|---|---|---|---|
| Marine‑grade plywood (CB‑X) | ¾ in | ≤0.2 % | 1.8 |
| Moisture‑resistant particleboard (MR‑PB) | ¾ in | ≤0.5 % | 1.6 |
| Solid surface (acrylic) | ½ in (top only) | 0 % | 2.0 |
Dimensional Specifications
Critical dimensions are standardized to facilitate rough‑in planning while allowing minor adjustments for site conditions.
| Parameter | Value | Tolerance |
|---|---|---|
| Overall Width | 72 in | ± 1/16 in |
| Overall Depth | 22 in | ± 1/16 in |
| Overall Height | 34 in | ± 1/16 in |
| Sink Basin Length (each) | 18 in | ± 1/16 in |
| Sink Basin Width | 14 in | ± 1/16 in |
| Sink Basin Depth | 6 in | ± 1/16 in |
Construction & Joinery
Panels are joined using cam‑lock fasteners supplemented with a bead of polyurethane adhesive along each joint, delivering a shear strength exceeding 800 psi in laboratory tests.
All exposed edges receive a 1‑mm PVC edge band sealed with hot‑melt adhesive, providing a barrier against water ingress and reducing edge swelling.
The countertop is bonded to the cabinet with a silicone‑based sealant that accommodates differential expansion while maintaining a watertight interface.
Installation Requirements
Secure the vanity to wall studs using two ½‑inch lag bolts per side, positioned at the upper and lower mounting brackets; this configuration resists a 250 lb lateral load without movement.
Plumbing rough‑in should place the drain centers 18 inches from the finished floor, with supply lines offset 4 inches from each sink centerline to accommodate standard faucet reach.
A minimum clearance of 2 inches behind the unit is recommended for service access to trap and shut‑off valves.
Applications & Use Cases
In hospitality settings, the dual‑sink layout supports simultaneous guest preparation during peak check‑in periods, reducing queue length and improving perceived service speed.
For multifamily residential projects, the standardized 72‑inch width aligns with typical master bathroom layouts, allowing developers to repeat a single SKU across multiple units while maintaining design consistency.
High‑end residential installations benefit from the seamless top, which accommodates premium edge profiles such as eased or ogee without additional fabrication steps.
Quality Assurance & Testing
Each finished unit undergoes a 48‑hour standing water test at the sink basin to verify absence of leaks at joints and seals.
Load testing applies a 200 lb uniform load across the countertop for 24 hours; deflection is measured and must remain below 0.010 inches to pass.
Cycle testing simulates 10,000 opening and closing motions of doors and drawers, verifying fastener retention and hinge wear within specified limits.
Customization Options
The following options are available to tailor the vanity to specific project requirements:
- Choice of substrate: marine‑grade plywood, moisture‑resistant particleboard, or solid surface.
- Finish: laminate, veneer, or painted surface in any RAL or NCS color.
- Hardware: soft‑close hinges, drawer slides, and handle styles (pull, knob, recessed).
- Sink material: vitreous china, stainless steel, or solid surface undermount.
- Top thickness: ½‑inch, ¾‑inch, or 1‑inch solid surface or quartz.
- Additional features: integrated LED lighting, electrical outlets, or towel bars.
