A water temperature cycling device for supplying intermittently hot and cold water for therapeutic benefits which has a cylindrical body (20) internally ported allowing water to drive a turbine (38) supplying rotational force to a rotor (48) through a speed reducing gear train (46). The speed of the cyclic action of the hot and cold water is governed by flow from a control valve (64) bypassing some of the flow from the turbine. The periodic repetitive changing from hot to cold is accomplished by a recessed portion (50) within the rotor (48). Each time the rotor makes a full rotation, the temperature changes completely as half of the circumference of the rotor is recessed. In another embodiment, the recessed portion is in a helical Archimedes curve shape allowing a more gentle effect. The device maintains a constant flow of combined hot and cold water regardless of the temperature change.
