PROBLEM TO BE SOLVED: To provide a bathtub washing apparatus which can determine that a stopper of other apparatus than the bathtub washing apparatus is opened resulting the use of supply hot water and the fact it is closed again by a bathtub washing apparatus without using other apparatus, even if a heat source machine controller and a washing controller are not linked together, and particularly which can be connected to a heat source machine made by the other maker. SOLUTION: If detected hot water filling rate Qd is not maintained within the tolerance range of setting rate of flow Qt in the bathtub washing apparatus side (S11, NO), in the next step, when hot water filling rate Qd exceeds the upper limit of the tolerance range for not more than 20 seconds, and it falls below the lower limit of the tolerance range for more than 20 seconds, it is judged that the other stopper is open, and hot water supply is to be continued (S22, NO, S23, YES, proceeding to S24). Next, it is judged whether the other stopper is closed again depending on whether or not hot water filling rate Qd exceeds the lower limit of the tolerance range of setting rate of flow Qt, with the counting of washing time stopped temporarily (S26-30).
