There are three main types of bathroom sinks: vanity, pedestal, and wall-hung. Vanity sinks sit on top of or within a vanity and provide ample storage space. Pedestal sinks take up less counter space but have no storage. Wall-hung sinks are mounted on the wall and also lack storage space. The material, shape, and faucet location of the sink should be considered to match the bathroom design and provide easy maintenance.
