What’s the difference between a dresser and a vanity? The sink, of course! And adding one is not so difficult if you’re hoping to include the charm of repurposed furniture in your bathroom redo. 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.
