A waterfall shower head works by diffusing the force of water flow and shaping the water in to a wide stream. It is able to achieve this with the unique shape. Instead of leaving the head through many tiny holes like in a traditional spout, water leaves through one long linear hole. Since the water is poured, and not sprayed, it can deliver larger amounts of water per second than its traditional counterparts. Waterfall shower heads have a unique shape, the head is usually shaped like a cylinder or long rectangle. Some just screw onto the existing base. These have a T-like shape. Some are installed directly in the shower stall wall via a console like fixture, or are just simply cut out and lined with a plate fixture.
