Sink Base Cabinet – Cabinet Glossary

What is a Sink Base Cabinet?

A Sink Base Cabinet is a lower cabinet modified to accommodate a sink. It has no top, partial back, and interior supports designed for plumbing.

Quick Facts About Sink Base Cabinets

• Widths: Commonly 30”, 33”, or 36” with some going narrower or wider.  
• Design: No top drawer.  Could have a false drawer front or could be full height doors.  Some applications will install tilt outs to make the false drawer fronts useable for storing small items like sponges.  
• Placement: Centered under a kitchen or vanity sink.  Typically placed centered under a window or in an island.  

Use Cases

• Installing a kitchen sink with plumbing access.  Typically a dishwasher will be placed on either side.  
• Pairing with farmhouse or apron-front sinks.
• Housing pull-out trash or cleaning supply storage adjacent to or below the sink.

Designer Tip

Choose a sink base cabinet that matches your sink width for a proportional, balanced look.
