Bathroom Vanities by Size

How to Choose Your Vanity Width

Width is the first filter, but not the only one. Before settling on a size, measure the wall space and account for door swing, nearby fixtures, and clearance to the toilet. Most installers suggest at least 15 inches from vanity edge to toilet centerline, and more in a shared bathroom. You'll also want 2 to 3 inches of breathing room on each side of the vanity so the doors and drawers open freely without bumping the wall or tub surround.

Standard Sizes vs. Non-Standard

The standard widths (24, 30, 36, 48, 60 inches) match typical rough-in plumbing positions. Swapping one standard size for another usually means no plumbing work at all. Stepping outside that range (18, 20, 28, 42, 54, 72 inches and up) may require adjusting supply or drain lines depending on your existing setup. Non-standard sizes aren't harder to install, but they're worth planning around because a plumber visit adds $200 to $400 to your project budget.

Sizing for Small Bathrooms and Powder Rooms

In tight spaces, the 24 inch bathroom vanity is the most popular choice. It gives you enough counter space for one person and stays small enough to leave the room functional. For a powder room vanity, even an 18-inch pedestal-style cabinet works when floor space is the priority. The key in small rooms is choosing a vanity that doesn't dominate the space visually. Wall-mounted and open-shelf designs help a compact bathroom feel larger than its footprint.

Sizing for Shared and Master Bathrooms

The 36 inch bathroom vanity is the single most common primary bathroom spec. It fits most wall openings and gives a single user generous counter on both sides of the sink. For two people sharing the same bathroom on the same schedule, a double sink bathroom vanity at 60 inches or wider solves the morning bottleneck. At 60+, each person gets their own basin and real counter space, which is the difference between "it works" and "we actually enjoy this bathroom."

Depth and Height Matter Too

Most vanities run 21 to 22 inches deep and 34 to 36 inches tall (including the top). If your bathroom is narrow, look for shallow-depth models at 18 inches deep that still provide a functional sink and some counter. Comfort-height vanities (36 inches) are easier on your back and match the height of most kitchen counters. Standard height (30 to 32 inches) works better in kids' bathrooms or homes with shorter users. Measure the space, then match the vanity to the people who'll use it every day.
