The Shower Enema Kit comes with two nozzles, one is 5 inches and the other is 3.5 inches. It also comes with a 6 foot metal hose. One end of the hose screws into your shower, the other end is where you attach your choice of nozzle. Where the Shower Enema Kit connects with your shower it has a valve that directs the water either through the nozzle and into you or to the shower head. Use the shower knob to regulate the force of water through the hose.
