PROBLEM TO BE SOLVED: To permit the operation of hot-water filling time precisely as well as the approximation of a reserved hot-water filling time to an actual finishing time of hot-water filling even when the hot-water is supplied to a bathtub and a place except the bathtub simultaneously. SOLUTION: A bath hot-water supplier is provided with a control means 17 for controlling so that hot-water filling into a bathtub 9 is started at a time retroactive to a reserved time of hot-water filling, which is set by a hot-water filling setting means 12, by the time of adding a surplus time T0 to a hot-water filling time Tq. In such a bath hot-water supplier, a flow rate detecting means 15 for detecting the flow rate of hot-water into the bathtub 9 and a flow detecting means 19 for detecting the supply of hot-water to a place except the bathtub are provided. The control means 17 measures a reference hot-water filling time Ty corresponding to a reference hot-water filling rate Qk upon supplying the hot-water to only the bathtub 9 based on the outputs of the flow detecting means 19 and the flow rate detecting means 15. The hot-water filling time Tq is operated from the filling time Ty, the reference hot-water filling amount Qk and a hot-water filling rate Qy, set by the hot-water filling setting means 12.
