Measuring a vanity
- Measure the cabinet’s width across the top, outside to outside.
- Measure the depth from the wall to the front of the doors.
- Add about 1 inch of overhang at the front, and at each side that does not meet a wall.
- Measure the height. Older vanities are often around 30 to 32 inches; newer “comfort height” ones are closer to kitchen height. A thinner or thicker top changes the finished height.
- Note the sink and faucet you plan to use, and where the plumbing comes through.
Which stones work best
A bathroom vanity sees water, soap and cosmetics, but rarely heat. Quartzite and granite are tough choices. Engineered quartz needs no sealing and resists makeup and hair dye stains. Dolomite and marble look beautiful but can etch from some toiletries and acidic cleaners, so wipe spills and use a tray for bottles. See countertop materials compared.
Making a vanity top from a prefab piece
Our 26-inch countertop piece will work for a vanity top with some trimming, and it comes with a backsplash. One long piece can sometimes cover two vanities. Your contractor, or one of our installation partners, trims it to length and cuts the sink and faucet holes. See the sizes page for lengths and today’s prices.
Sinks for a vanity
- Undermount: clean, easy to wipe, the most common choice with stone.
- Vessel: sits on top of the counter; needs only a drain hole and a taller faucet.
- Drop-in: easy to install and replace.

Common questions
Can I use a kitchen countertop piece for a bathroom vanity?
Yes. Our 26-inch piece will work for a vanity top with some trimming.
How much overhang should a vanity top have?
About 1 inch at the front and at any open side.
Is quartz or granite better for a bathroom vanity?
Both work well. Quartz needs no sealing; granite costs less in many colors. A vanity sees little heat, so quartz’s main weakness rarely matters there.
