How to Measure for a Bathroom Vanity

Buying a bathroom vanity that does not fit is a frustrating and expensive mistake. A few careful measurements before you shop save you from returns and renovation headaches. Here is exactly what to measure to get the right size vanity.

Measure the Available Width

Width is the most important dimension. Measure the wall space where the vanity will go, then account for clearances:

• Leave room for the door to open and for walking past
• Check that drawers and doors can open without hitting a wall, toilet or shower
• If the vanity sits between two walls, measure at several heights, since walls are not always square

Vanities come in standard widths, so measure first, then choose the largest size that fits comfortably.

Check the Depth

Depth affects how far the vanity projects into the room. Standard vanities are around 21 inches deep, with shallower options for tight spaces. Make sure the depth leaves comfortable clearance in front and does not block a door or traffic path.

Consider the Height

1. Standard height vanities suit most bathrooms and children
2. Comfort or counter height vanities are taller and easier on the back for adults
3. Choose based on who uses the bathroom most

Locate the Plumbing

Measure where the water supply lines and drain come out of the wall or floor, both height and distance from the side wall. The vanity and sink need to work with this plumbing, or you will need to adjust it. This is especially important for vanities with drawers, where the plumbing has to be accommodated.

Single or Double

If your width allows, decide whether you want one sink or two. A double vanity generally needs a wider space to be comfortable. Once you have your width, depth, height and plumbing location, you can shop with confidence. Browse our bathroom vanities by size, from single sink to double sink models.
