White Shaker Sink Base Cabinet 42" Wide

42-Inch White Shaker Sink Base Cabinet

The WSB42 is the largest White Shaker Sink Base Cabinet in this series. Featuring two doors and a false drawer front, it provides maximum interior space for larger kitchen sinks, plumbing components, garbage disposals, and water filtration systems while maintaining the timeless appearance of a classic Shaker kitchen.

Unlike a standard base cabinet, a sink base cabinet is specifically designed to accommodate sink plumbing. The open interior provides generous working room for installation, future maintenance, and additional accessories installed beneath the sink.

Choosing the Right Sink Base Cabinet

One of the most common mistakes homeowners make is selecting 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 42-Inch Sink Base Cabinet?

The WSB42 provides the maximum amount of interior space available in this sink base series. It offers outstanding flexibility for larger sinks while giving plumbers ample room for garbage disposals, water filtration systems, and future plumbing maintenance.

If your kitchen layout comfortably accommodates a 42-inch sink base, it provides the greatest flexibility for sink selection and under-sink storage.

Common Applications

• Primary kitchen sink locations
• Large kitchen remodels
• New construction kitchens
• Farmhouse-inspired kitchens
• Luxury kitchens
• Large prep kitchens

42-Inch vs. 39-Inch Sink Base Cabinet

The 39-Inch White Shaker Sink Base Cabinet offers generous room for most kitchen sink installations while requiring less cabinet space.

Choose the WSB42 when your sink manufacturer recommends the additional width or when you simply want maximum room for plumbing installation, garbage disposals, water filtration systems, and future maintenance.

Built for Plumbing Access

The open sink base interior provides unobstructed space for drain lines, water supply connections, garbage disposals, water filtration systems, and other plumbing components. The false drawer front preserves the appearance of a traditional base cabinet while allowing the sink basin 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 significantly easier.

Built to Last

Built in America, the WSB42 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.
