An improved fluid dispenser for a shower bath is disclosed for mounting between a pressurized water pipe and a shower nozzle. The dispenser includes a body portion having a water channel connected between the pipe and the nozzle and a dispensing channel opening into the water channel at a lower end thereof and opening onto an upper surface of the body at an upper end thereof above the water channel. A fluid reservoir is mounted on top of the upper surface of the body, having a drain opening into the dispensing channel, for storing the fluid to be dispensed. A valve seat composed of a high lubricity fluorocarbon resin is mounted in the dispensing channel, having a hole therethrough communicating between the upper end of the dispensing channel and a lower surface of the valve seat. A cylindrical valve composed of a high lubricity fluorocarbon resin is rotatably mounted horizontally in the body with a circumferential surface in sealable contact with the lower surface of the valve seat. A transverse hole passes through the cylindrical valve, which selectively communicates between the lower end of the dispensing channel and the hole in the valve seat in response to axially rotating the cylindrical valve in the body. In this manner, a leakless fluid dispensing valve is provided for the shower bath dispenser.
