1. A shower head capable of alternately dispensing a fine, steady stream and a heavier, pulsating stream with a massaging effect, includinga housing having a water inlet and a water outlet,a face plate covering said outlet, said face plate being generally circular and including an outer peripheral set of fine outlet holes and an inner set of larger outlet holes, said plate including at least one radial, pulse-averaging channel leading to said fine outlet holes,a rotatable dial plate within said housing and contiguous with said outer cover, said dial plate having openings therein positioned to be in alignment with said channel when in one rotative position and with said larger holes when in a different rotative position, and means associated with said dial plate for rotating same from one position to the other,an inlet chamber within said housing, said chamber being formed by said dial plate, sides, and an upper wall portion, said upper wall portion having a central opening therein to receive water from a water inlet,a spinner mounted for rotational motion within said chamber and positioned to receive all water entering through said central opening, said spinner being adapted to discharge said water into said chamber in a direction to rotate said spinner,vanes associated with said spinner to be rotated thereby, said vanes being positioned above and adjacent to said rotatable dial plate and being dimensioned so as to periodically cut water passing from said chamber through the holes to create a pulsating motion in said water,whereby said shower head may provide a pulsating stream of water from said larger holes and a steady stream of water from said finer holes and permit the user to select the type stream desired.
