Today's styles include vanities that are mounted on a wall, nothing more than a countertop and sink. These give a sleek, modern appeal and can be enhanced with lighting from underneath.
Others are furniture-style vanities, which have the appearance of a dresser or similar piece of furniture. These can give you a great style boost, but may add height to your sink and faucet, making it harder for younger family members to use it.
Open shelving can create a simple minimalist look, but the traditional drawers and cabinet doors help if you need to quickly stash the mess when unexpected company arrives.
