Abstract: A pulsating shower head that employs a rotor for effecting the discharge of a variable pulsating spray, a variable continuous spray, or a combination of both comprising an upper body housing, a rotatable lower body housing, a stationary stem housing affixed to the upper body housing, an O-ring retainer affixed to the stem housing, and a stem--rotor housing assembly that moves axially when the lower body housing is rotated. An O-ring affixed to the stem acts in conjunction with the O-ring retainer to open and close a water channel leading to a pulse chamber. At the same time, O-rings affixed to the stem housing act in conjunction with the rotor housing to open and close a water channel leading to a continuous spray chamber. Rotation of the lower body housing results in either a continuous spray, pulse spray, or combination continuous and pulse spray. The shower head may be incorporated into either a wall mounted unit or a hand held unit.
