33-Inch White Shaker Sink Base Cabinet
The WSB33 is one of the most popular White Shaker Sink Base Cabinets for today's kitchens. Featuring two doors and a false drawer front, it provides the open interior needed for sink plumbing while maintaining the timeless appearance of a classic Shaker kitchen.
Unlike a standard base cabinet, a sink base cabinet is specifically designed to accommodate drain lines, water supply connections, garbage disposals, and other plumbing components while providing easy access for future maintenance.
Choosing the Right Sink Base Cabinet
One of the most common mistakes homeowners make is choosing a 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 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 33-Inch Sink Base Cabinet?
The WSB33 is one of the most versatile sink base cabinet sizes available. It accommodates a wide variety of kitchen sinks while providing generous room for plumbing installation and future maintenance.
If your kitchen layout has room for a 33-inch sink base, it is an excellent choice for homeowners who want flexibility when selecting a sink without stepping up to a larger cabinet than necessary.
Common Applications

33-Inch vs. 30-Inch Sink Base Cabinet
The
30-Inch White Shaker Sink Base Cabinet
is an excellent choice when cabinet space is more limited or when the selected sink requires a smaller cabinet.
Choose the WSB33 when your layout allows. The additional interior width provides more flexibility for sink selection while making plumbing installation and future service easier.
Built for Plumbing Access
The open sink base interior provides unobstructed space for drain lines, water supply connections, garbage disposals, and other plumbing components. The false drawer front preserves the appearance of a traditional base cabinet while allowing the sink and plumbing to occupy the space behind it.
Our two-door 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 WSB33 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.
