Bathroom Vanity Cabinets Without Tops
Bathroom vanity cabinets sold as base-only units let you pair a quality cabinet with the exact countertop, sink, and faucet you want. This cabinet-only configuration is ideal when you already have a slab remnant, plan to install a custom stone top, or need to match an existing vanity in a double-sink layout.
Because no top is included, you save on shipping weight and avoid paying for a surface you don't plan to use. Contractors and renovators often prefer this route when fabricating a custom marble, quartz, or butcher block counter. Explore the full range of bathroom vanities or narrow your search by wall-mount cabinets and double-sink cabinet bases.
Sizes range from compact 24-inch bases for powder rooms to 84-inch doubles for master suites, in finishes from crisp white to walnut.

Frequently Asked Questions
What does "cabinets only" mean for a bathroom vanity?
Cabinets only means the vanity ships as a base cabinet without a countertop, sink, faucet, or backsplash. You receive the finished wood or MDF cabinet box with doors, drawers, and hardware installed. This setup is intended for buyers who plan to source a custom stone, quartz, or wood top separately and pair it with their own sink.
Why buy a vanity cabinet without a top instead of a complete set?
Buyers choose cabinet-only vanities when they want a custom countertop material — like a marble remnant, waterfall quartz edge, or live-edge wood slab — that isn't offered in a complete set. It's also common in renovations where a fabricator is already templating adjacent surfaces, or when matching an existing vanity's top material in a his-and-hers layout.
How do I measure for a countertop on a cabinet-only vanity?
Measure the cabinet's exterior width and depth, then add your desired overhang — usually 1/2 inch on the front and any exposed side, and flush to the wall at the back. Most bathroom tops run 22 inches deep for a standard 21-inch cabinet. Always have your fabricator template in-person after the cabinet is leveled and secured.
Can I install a vessel sink on any cabinet-only vanity?
Most cabinet-only bases accept a vessel sink, but you must verify the faucet height clears the bowl rim and that the cabinet top is sealed or finished if exposed. Vessel sinks require a single small drain hole rather than a large sink cutout, giving you more design flexibility. Check the cabinet height — standard 32 to 34 inch bases plus a 5 to 6 inch vessel can feel tall for shorter users.
Does a cabinet-only vanity include a drain or plumbing?
No. A cabinet-only vanity ships with the cabinet box and hardware only — no drain assembly, P-trap, supply lines, faucet, or sink. You'll need to purchase these separately along with your countertop. The cabinet typically has an open back or a removable panel to accommodate standard rough-in plumbing at 18 to 22 inches off the floor.
