What’s the difference between a dresser and a vanity? The sink, of course! If you’re planning to redo your bathroom and happen to stumble upon an old dresser of the right dimensions, consider giving it a second life as a vanity. Purchase a self-rimming sink, cut a hole in the dresser top to accommodate it, and cut holes as necessary in the back for the plumbing. Then, hook up the faucets, give the vanity a coat of paint, attach the unit to the wall, and lather up.
