Along with kitchens, bathrooms offer one of the best returns on your renovation dollars. And one of the easiest ways to update your bathroom is to replace the vanity, countertop, sink, and faucet. For a few hundred dollars, you can really freshen the space, while for $1,000 or more, you can add that upscale spa-like look to your bathroom. The first step in this easy renovation is to remove the old vanity, which takes less than an hour.
Installing a new vanity is easiest with a unit that includes a countertop with an integrated sink. The vanity cabinet is separate from the top. The cabinet has an open top and back, so it’s easy to set in place and fasten from above. Once the cabinet is secured, the countertop-sink unit is dropped in, usually with the faucet pre-installed. The final step is making the water supply and drain connections. Some vanity sets include a separate backsplash piece. This is typically installed with caulk or adhesive after the countertop is secured.
