30 Inch Bathroom Vanities with Sink
A 30 inch vanity with sink hits the sweet spot between the ultra-compact 24-inch and the more generous 36-inch widths, giving you an extra six inches of countertop without sacrificing floor space in a guest bath or secondary bathroom. At this width, you get room for a soap dispenser, toothbrush holder, and hand towel on the counter — something a 24-inch vanity simply cannot accommodate.
Every unit at 30 inches wide is a single-sink configuration — double bowls require a minimum of 60 inches, so shoppers at this size should focus on basin shape, drawer layout, and faucet hole spacing. Explore the full range of bathroom vanities or step up to a 36-inch model if you need more storage.
Plumbing rough-ins typically fall 4-8 inches off-center in 30-inch cabinets, so confirm your drain location before ordering.

Frequently Asked Questions
Will a 30 inch vanity fit in a small bathroom?
A 30 inch vanity works well in bathrooms with at least 36 inches of dedicated wall space, leaving 3 inches of clearance on each side for trim and outlet boxes. It's a strong choice for 3/4 baths and guest bathrooms between 35 and 50 square feet, where a 24-inch feels cramped and a 36-inch blocks the door swing.
Can I get a double sink on a 30 inch vanity?
No. Double-sink vanities require a minimum width of 60 inches to provide adequate space between bowls and usable counter area. At 30 inches, you're limited to a single basin — either centered or offset. If two sinks are essential, consider pairing two 30-inch single vanities side by side for a 60-inch double configuration with separate plumbing.
How much storage does a 30 inch vanity offer?
Expect roughly 6-8 cubic feet of interior storage — enough for towels, cleaning supplies, and personal care items for one user. Most 30-inch models offer either two doors with a single shelf, or a door-plus-drawer layout. Drawer configurations are more efficient at this width since the P-trap consumes less usable cabinet depth on the drawer side.
What faucet size works best on a 30 inch vanity top?
A 4-inch centerset or single-hole faucet is the best match for a 30-inch top. An 8-inch widespread faucet can fit, but it leaves minimal counter space on either side of the handles. For vessel sinks, choose a tall single-hole faucet — vessel bowls eat more counter real estate, making faucet compactness critical at this width.
Are 30 inch vanities available as floating wall-mount units?
Yes, floating 30-inch vanities are widely available and particularly popular at this size because the visible floor underneath makes small bathrooms feel larger. Installation requires solid wood blocking between studs to support the cantilevered weight. Plan mounting height between 30 and 34 inches from the finished floor to the top of the counter.
