For use as a shower attachment. The nozzle is 6" (15cm) long, attached to a metal hose 1.7 meters (almost 6 feet) long. On the other end is a valve which is designed to screw into your shower. Then both your shower head and the 6-foot hose attach to the valve. In one position, the valve will direct the water flow to the Shur Shot, and in the other position the water goes straight to the shower head as it normally would.
