This is a very neat enema system. Its douche/enema nozzle is outfitted for use as a shower attachment.
The Shower Enema Kit comes with 3 nozzles.
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.
