A bathroom vanity should fit more than the empty space against your wall. It also needs to work with your plumbing, door swing, storage needs, and daily routine.
Before shopping, take a few measurements and photos. They can help you avoid buying a great-looking vanity that turns into a difficult installation.
Start with width
Common vanity widths include 24, 30, 36, 48, 60, and 72 inches, with other sizes available depending on the collection. These are shopping categories, so check the exact dimensions of the product you are considering.
Measure the available space at several points, especially if the vanity will sit between two walls. Check whether trim, baseboards, or uneven walls reduce the usable width. Also confirm the countertop dimensions: the top may extend beyond the cabinet.
Check depth and the space in front
A vanity can fit along the wall and still make a bathroom feel cramped. Measure from the back wall toward the front edge of the proposed vanity, then check the remaining space for movement.
Open the bathroom door and nearby shower door. Consider whether vanity doors and drawers can open comfortably without hitting another fixture. Use painter’s tape to mark the footprint on the floor if you want to visualize the fit.
Consider the finished height
Compare the listed vanity height with your existing setup and the people who will use it. Check whether the measurement includes the countertop, sink, and legs.
For a wall-mounted vanity, the installed height depends on placement. Confirm the manufacturer’s mounting requirements and discuss wall support and plumbing with your installer before purchasing.
Match the vanity to your plumbing
Take a photo of the plumbing inside your current vanity. Note where the drain and water lines enter, and compare that location with the new cabinet’s interior layout.
Drawer configurations can be particularly important. A vanity that is the right width may still need plumbing changes if its drawers occupy the space where your existing pipes sit. Ask your installer to review the product before ordering if compatibility is unclear.
Decide between one sink and two
A wider vanity does not automatically require two sinks. A single-sink model can provide more uninterrupted counter space, while a double-sink model can serve two people at the same time.
Think about how you use the bathroom and check the specific cabinet’s storage layout. If you are changing from one sink to two, have your installer assess the plumbing work first.
Measure the route into your home
Your vanity also needs to fit through doorways, hallways, stairways, and tight turns. Check both product and packaged dimensions before pickup. Confirm whether a countertop is separate or attached rather than assuming the unit can be taken apart.
Bring these details when you shop
- Maximum usable width, depth, and desired height.
- Photos of the bathroom and existing plumbing.
- Notes about door swings and drawer clearance.
- Your preference for wall-mounted or freestanding installation.
- The narrowest doorway or turn on the delivery route.
Taking these details with you makes it easier to compare products and ask useful questions. Final installation compatibility should be confirmed with your installer.
