Even the simplest of bathroom vanities and sinks can be elevated with a beautiful faucet, whether you love the intricate, vintage look of a bridge-style faucet, or the sleek, contemporary lines of a streamlined model. Swapping out a faucet is a relatively simple DIY task, as long as you are putting it in the same spot. If you want to move the sink entirely or add new water lines, it's best to call a plumber.
