Abstract: A control for controlling the flow of water to a bathtub and shower which may be readily assembled using standard electrically operated valves. The control includes a pair of electrically operated variable position valves, one in each of the hot and cold water supply pipes or lines for regulating the flow of water through the associated line. A manifold is provided downstream of the hot and cold water supply lines. A pair of pipes or lines extend away from the manifold to the tub and to the shower, each line being provided with a normally closed electrically operated “on/off” valve. An electrical control circuit is provided for operating the various valves so that water flow can be initiated either to the bathtub faucet or to the shower head, and so that hot and cold water flow rates may be varied.
