PROBLEM TO BE SOLVED: To improve quality at installation by automatically setting a water level set value at a trial operation time and executing an accurate trial operation in a short time. SOLUTION: An automatic bath system comprises a hot water supply unit 1 for supplying hot water to a hot water supply port at a lower part of a bathtub, a water level detector 2 for detecting a water level in the bathtub, an operating unit 3 for selecting the operation and setting a desired hot water filling level, a display unit 6 for displaying an operating state and a set water level, a hot water supply amount detector 4 for detecting a hot water supply amount supplied by the unit 1, a controller 5 for calculating a hot water supply amount necessary to fill the hot water to the set level set by the unit 3 from a present water level detected by the detector 2 to control the unit 1, and a set water level altering unit 7 provided separately from the unit 3. In this system, the system is normally operated based on the set level decided by the unit 3, and when a predetermined operation is executed by the unit 3, the system is operated based on the set level decided by the unit 7.
