How to Measure for a Bathroom Vanity
Grab your tape measure and follow these steps to find the bathroom vanity dimensions you need for your upcoming project.
Determine Project Scope
If you're replacing an existing vanity with the same size, simply measure the length, width, and depth of your current vanity and choose a replacement with the same dimensions. If you're starting from scratch, your bathroom's available space will determine your next steps.
Measure the Width of Your Space
To find the width of your space, measure from wall to wall (side to side), taking into account where your bathroom and shower doors swing. Make sure these doors won't hit your vanity. To accommodate a single-sink vanity, you'll need at least 18 inches of width available. For a double-sink vanity, you'll need at least 48 inches of width available. Remember that the vanity top will typically add ½ inch to 1 inch on either side of the vanity width.
Measure the Depth of Your Space
To find the distance of usable space, measure from the back wall outward. Remember, you'll need clearance for vanity drawers and doors to open, and enough room for a person to pass by easily. We recommend at least 30 inches of clear floor space in front of your vanity in order to feel comfortable walking through. The most common vanity depths are 17 to 24 inches.
Measure the Height of Your Space
To find the right height for your vanity, measure from the floor up. Make sure to factor in faucet height and existing features, like the placement of a potential backsplash and electrical outlets. For floating vanities, adjust the mounting so your countertop sits waist-high (or slightly lower for small children). The standard vanity height is 30 to 36 inches.
💡 Pro Tip
Need help picking the perfect vanity? Consider the overall style of your bathroom, storage requirements, and whether you need single or double sinks based on how many people will be using the space daily.
Additional Bathroom Vanity Size Considerations
After you've measured your space, there are a few other factors you'll want to keep in mind.
Bathroom Layout
Make it fit
Measure the width, height, and depth of the intended vanity location of the current vanity you are replacing.
Maintain clearances
Consider how much room you'll need for walking, plan for door swings and shower and shower pull-out space. Try to maintain at least 27 inches of space in front of the vanity for walking and opening vanity cabinet doors.
Adhere to compliance
Ensure the center of your toilet is at least 18 inches from vanity's side, and the bathtub has a minimum of 15 inches of clearance space.
Fixture Compatibility
Plan your faucet
Ensure the faucet spout will reach the sink and the number of faucet installations holes match the vanity configuration.
Scale
Ensure the width of your vanity is to scale with existing mirrors or medicine cabinets.
Identify existing elements
Finalize where the water from your sink needs to flow here, plus any outlets or electrical switches.
