Fluid mixing and dispensing shower head and suspendible supply reservoir for portable connection to a conventional shower head. The valve block is constructed for quick, intermediate securement between the shower head and supply pipe and is adapted to be operated in conjunction with the shower fixture for selectively dispensing one of a plurality of select liquids into the water stream discharged by the shower nozzle. A plurality of separately accessible containers are provided in a storage bracket suspended beneath the shower head to store distinct quantities of fluids to be dispensed. A suitable selector valve is provided adjacent the storage reservoir to channel the select fluid into the shower head. The containers are housed in a transparent bracket, suspended from the shower head, to permit the user to determine the amount of liquid remaining in each container and the type of liquid selected. A valve is also provided in the shower head for selectively controlling the amount of fluid dispensed through the shower head. The valve has a select passageway positionable within said inlet and outlet when the valve is in a certain position to effect the supply of clear water through the shower nozzle and/or any of the select liquids provided therebeneath.
