What Are the Standard Vanity Dimensions?

Standard vanity dimensions are typically between 18" – 72" wide. For a single vanity, the most popular widths are 24", 30", 36", 48", and for double vanities the most popular widths are 60" and 72" but start at 48". The standard depth of a vanity is typically around 20", but narrower options are available. The standard vanity height is 32", but ranges from 30" – 36" tall.

How to Measure for a Bathroom Vanity

Grab your tape measure and follow these steps to find the bathroom vanity dimensions you’ll need for your upcoming project.

Step 1: 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 dictate your next steps.

Step 2: 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" of width available. For a double-sink vanity, you’ll need at least 48" of width available. Remember that the vanity top will typically add 1/2" to 1" on either side of the vanity width.

Step 3: 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" of clear floor space in front of your vanity in order to feel comfortable walking through. The most common vanity depths are 17" – 24".

Step 4: 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" – 36".

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 or of the current vanity you are replacing.
• Maintain clearances: Consider how much room you’ll need for walking; plan for door swings and drawer pull out space. Try to maintain at least 21" 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" from vanity’s side, and the bathtub has a minimum of 30" of clearance space.

Fixture Compatibility

• Plan your faucet: Ensure the faucet spout will reach the sink and the number of faucet installation holes match the vanity.
• Scale: Ensure the width of your vanity is to scale with existing mirrors or medicine cabinets.
• Identify existing elements: Review where the water from your sink needs to flow from, plus any outlets or electrical switches.

Bathroom Type

• Powder room or half-bath: Petite vanities measuring 24" – 30" wide are best suited for compact bathrooms. Very small bathrooms may even benefit from a shallow or floating wall-mounted vanity to maximize the limited space.
• Shared bathroom: Shared bathrooms should have a slightly wider single-sink vanity that ranges from 36" – 48" wide. Though these vanities only have one sink, the additional counter space and storage will be helpful for sharing a bathroom.
• Primary bathroom: A wide double-sink vanity that is 60" – 72" wide is a great option for a shared primary bathroom. With two sinks and ample counter space, double vanities ensure both people have plenty of room to get ready at the same time.
