An automatic water level control system for a bathtub is provided whereby the user merely sets a manual control to a desired water level. The control system then sequentially closes the bathtub drain and turns on the water faucet. The water faucet is preferably of the temperature mixing type which has previously been pre-set by the user, so that water at a desired temperature flows into the tub. When a selected, pre-set level has been reached, the water is automatically turned off and the bath is ready. The control system uses solenoid controlled valves connected to the usual manually controlled valves in such a manner that the normal manual control of the bath water is not interfered with in any way when the automatic control system is not activated.
