The right vanity size makes a bathroom feel considered rather than cramped. Before you choose a finish, get the measurements right. This bathroom vanity size guide covers how to measure your space, the standard widths and depths, and when to size up to a double.
How do I measure my bathroom for a vanity?
Measure the full width of the wall, the available depth, and the position of your plumbing rough-in, then note anything that intrudes: the door swing, a toilet, or a shower enclosure. Bring those numbers when you shop. Leaving a few inches of clearance on each side keeps drawers and doors working freely.
What are the standard bathroom vanity widths?
Our bathroom vanities run from 30 to 71 inches wide. As a quick guide, 30 to 31 inches, like the MONACO, suits powder rooms and compact baths; 35 to 48 inches, like the TULUM or HAVANA, fits most standard bathrooms; and 59 to 71 inches, like the MALDIVES, is built for primary suites.

What size vanity fits a small bathroom?
For a small bathroom or powder room, choose a 30 to 31-inch vanity such as the MONACO, BALI, or ASPEN. A floating model like the TULUM also makes a small room feel more open, because the exposed floor beneath it is easy to clean around. Leave room for the door to swing clear.
How much clearance should a vanity have?
Aim for at least 30 inches of clear floor space in front of the vanity, with about 21 inches as the practical minimum, so it feels comfortable to use. Leave a few inches between the vanity and any side wall or fixture so drawers and doors open fully. In an alcove between two walls, measure the opening precisely and size down slightly for an easy fit.
How deep are bathroom vanities?
Most of our vanities are about 16 to 20 inches deep, which balances basin size against the floor space you keep clear. In a narrow or high-traffic bathroom, choosing the shallower end of that range preserves the walkway; in a larger room, a deeper cabinet gives you a bigger basin and more counter space.
What height should a bathroom vanity be?
A floating vanity is typically mounted so the countertop sits 32 to 36 inches from the floor, adjusted to your comfort. Because a floating model carries its weight on the wall, it secures into the studs, so professional installation is worth it. You will find model-specific mounting guidance on our FAQ page.
