Measure Your Vanity Footprint
When bathrooms are built, vanities are installed before the flooring. That means your flooring ends at your vanity. If you’re replacing the vanity, buy one that’s the same length and width as your existing vanity (or larger).
Otherwise, you’ll end up with gaps between the vanity and the flooring. Or replace the flooring too. Then you can install a new vanity (any size!) and butt the flooring against it.
“Vanities take a beating from water spills, bathroom humidity and everyday use, so new cabinetry can make a dramatic improvement,” Lori Jo says.
