Abstract: A shower head adapted to mix and dispense a detergent and water is disclosed. A rotational shaft with impeller blades mounted on one end and a rotary brush engaging a detergent bar on the other end is rotated in a shower head when water under pressure flowing through the shower head impinges on the blades. Means are employed to keep the rotary brush in contact with the detergent bar when the detergent bar is being consumed during use. Means for diverting water toward or away from the impeller blades are also provided so that a bather may adjust the shower head during use to provide water or a mixture of water and a detergent.
