PROBLEM TO BE SOLVED: To provide a warm bath system by which heat radiation at the time other than bathtub-using time is effectively prevented so as to save power supply and also a water saving effect is realized. SOLUTION: This warm bath system is provided with a bathtub 1 and an overflow tank 3 capable of recovering the entire bathtub water. During the bathtub use, the overflow water of the bathtub is supplied to the overflow tank, filtered and sterilized with ozone, a temperature in a heat exchanger 9 is elevated and then the water is returned to the bathtub. Immediately after bathing, all the hot water in the bathtub is recovered to the overflow tank, circulated and sterilized with chlorine, then a filter 5 is back-washed. During the use-suspension period, the water is maintained at a set temperature. Immediately before the bathing time, the water is filtered in the overflow tank, sterilized with the ozone and the chlorine, the temperature in the heat exchanger 9 is elevated and the warm water is returned to the overflow tank. After the temperature is elevated to a desired level, the warm water is supplied to the bathtub.
