White Shaker Vanity Sink Base Cabinet 30" Wide

30-Inch White Shaker Vanity Sink Base Cabinet

The WVSB30 is one of the most popular White Shaker Vanity Sink Base Cabinets for today's bathrooms. Featuring two doors and a false drawer front, it provides generous room 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 offering ample space for plumbing and under-sink storage.

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 30-Inch Vanity Sink Base Cabinet?

The WVSB30 is one of the most versatile vanity sink base sizes available. It accommodates a wide variety of bathroom sinks while providing generous room for plumbing installation and future maintenance.

For many bathrooms, a 30-inch vanity sink base offers an excellent balance between sink size, cabinet size, and comfortable floor space.

Common Applications

• Primary bathrooms
• Secondary bathrooms
• Guest bathrooms
• Bathroom remodels
• New construction bathrooms

30-Inch vs. 27-Inch Vanity Sink Base Cabinet

The 27-Inch White Shaker Vanity Sink Base Cabinet is an excellent choice when preserving cabinet space is the priority.

Choose the WVSB30 when your layout allows. The additional cabinet width provides greater flexibility for sink selection and more working room for plumbing installation 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 WVSB30 features a solid poplar face frame, solid poplar Shaker doors with recessed birch plywood center panels, and a durable birch plywood cabinet box. We build our cabinets using hardwood and furniture-grade plywood—never MDF, particleboard, or engineered wood products—for long-term strength, durability, and dependable everyday performance.

Soft-close concealed hinges provide smooth, quiet operation. The cabinet is factory finished with Sherwin-Williams White and arrives ready for installation.
