Abstract: A shower accessory system comprises a housing having a central component with a sidewall formed with a central chamber having an input region and an output region. The central component has a circular upper opening in the top and a circular lower opening in the bottom. A water wheel is mounted in the upper opening for rotation and for being propelled by a flow of water through the central component. An upper component of the housing has a sidewall with an upper opening and a lid removably coupled to the sidewall to form an upper chamber. The upper chamber has a central gear coupled to the water wheel with a common axis for rotation therewith. A lower component of the housing has a sidewall and an open bottom and a sponge mounted therein. A spindle couples the sponge holder and the water wheel for rotating the sponge upon rotation of the water wheel about a common axis.
