PROBLEM TO BE SOLVED: To provide a bath system capable of preventing generation of an accident during bathing by announcing it to a bathing person by voice if a prescribed time passes after the person starts bathing for calling the person's attention. SOLUTION: A first water level is detected when hot water at a prescribed temperature is put in a bath, the detected first water level is canceled when hot water is added to the bath later, and a second water level is detected at the time of stopping adding hot water. A water sensor determines that a person is bathing when the water level in the bath is beyond the first or the second detected water level by a prescribed amount. When the water sensor does not detect water level lower than the first or the second water level for a certain regulating time, the sensor judges it as the person bathing for over a regulating time, and makes a voice alarm to announce emergency.
