27-Inch Unfinished Shaker Vanity Sink Base Cabinet
The UVSB27 is a 27-inch-wide Unfinished Shaker Vanity Sink Base Cabinet designed for bathrooms where you need a little more sink and plumbing space while maintaining a compact vanity footprint. Featuring two doors and a false drawer front, it provides the open interior required for sink plumbing while maintaining the timeless appearance of a classic Shaker vanity.
Built with a bathroom-friendly 21-inch depth, this cabinet provides more comfortable floor and walkway clearance than a standard 24-inch kitchen cabinet while still providing generous room for sink plumbing.
Choosing the Right Vanity Sink Base Cabinet
One of the most common mistakes homeowners make is selecting a vanity sink base cabinet based only on the outside dimensions of the sink.
The usable interior width of every cabinet is approximately 1.5 inches less than the listed cabinet width. Always verify the sink manufacturer's recommended minimum cabinet size before placing your order.
For drop-in vanity sinks, the cabinet only needs to accommodate the portion of the sink below the countertop. Undermount sinks require additional clearance for mounting hardware, so always review the sink manufacturer's specifications before selecting a cabinet.
Why Choose a 27-Inch Vanity Sink Base Cabinet?
The UVSB27 provides more flexibility than the
24-Inch Unfinished Shaker Vanity Sink Base Cabinet
while remaining an excellent choice for powder rooms, guest bathrooms, and secondary bathrooms. The additional cabinet width makes sink selection easier and provides more room for plumbing installation.
If your bathroom layout has room for the
30-Inch Unfinished Shaker Vanity Sink Base Cabinet,
we generally recommend moving up in size. The additional width provides even greater flexibility while maintaining the same bathroom-friendly 21-inch depth.
Common Applications
- Secondary bathrooms
- Guest bathrooms
- Powder rooms
- Small bathroom remodels
- Laundry room vanities
27-Inch vs. 24-Inch Vanity Sink Base Cabinet
The
24-Inch Unfinished Shaker Vanity Sink Base Cabinet
is an excellent choice when preserving every inch of available wall space is the priority.
Choose the UVSB27 when your layout allows. The wider cabinet provides greater flexibility for sink selection and more room for plumbing while maintaining the same bathroom-friendly depth.
Built for Bathroom Plumbing
The open vanity sink base interior provides unobstructed space for drain lines, water supply connections, shutoff valves, and other plumbing components. The false drawer front preserves the appearance of a traditional vanity while allowing the sink basin to occupy the space behind it.
Our two-door vanity sink base cabinets are built without a center stile between the doors, providing full access to the cabinet interior during installation and making future plumbing repairs much easier.
Built to Last
Built in America, the UVSB27 features a premium solid maple face frame, solid maple Shaker doors with recessed maple plywood center panels, and a durable birch plywood cabinet box. Unlike many mass-produced cabinets, we build our cabinets using premium solid hardwood and durable plywood construction—never MDF, particleboard, or other engineered wood products—for long-term strength, durability, and dependable everyday performance.
Soft-close concealed hinges provide smooth, quiet operation. The unfinished maple exterior is ready for paint, stain, or clear coat, while the cabinet interior already includes a clear natural protective finish.

Before ordering, verify your vanity layout, sink manufacturer's minimum cabinet requirement, plumbing location, countertop dimensions, neighboring cabinets, fillers, and available wall space.

Finishing Your Unfinished Maple Vanity Cabinet
The unfinished maple exterior can be painted, stained, or clear coated to coordinate with your bathroom. Maple can absorb stain unevenly, so proper preparation with a quality wood conditioner or sanding sealer is recommended before staining.
Before finishing your cabinet, review our
Cabinet Finishing Guide for Unfinished Maple Cabinets.
The cabinet interior already includes a clear natural protective finish and should not be painted or stained.
Assembly & Installation
The cabinet ships Ready-to-Assemble using our pocket screw construction system. The doors arrive pre-hung, and complete assembly instructions are included.

Professional Recommendation
The UVSB27 is an excellent choice when you want a little more flexibility than a 24-inch vanity provides while maintaining a compact bathroom layout. It works particularly well in guest bathrooms and secondary bathrooms where additional sink options are desired.
Before purchasing any vanity sink base cabinet, always verify the sink manufacturer's minimum cabinet size requirements. Spending a few minutes confirming compatibility before ordering helps ensure a smooth installation and a vanity that performs exactly as expected.
