PROBLEM TO BE SOLVED: To provide a bath water using system which can selectively switch applications of water in a bathtub to drainage and to effective use, and can effectively use the entire bath water. SOLUTION: According to the bath water using system, first and second drain valves 3, 4 are arranged across a drain passage 2 of the bathtub 1 at respective intermediate locations, and a branch passage is branched from the drain passage at some midpoint between the first and second drain valves 3, 4, as an application channel 5. When the first and second drain valves 3, 4 are both "opened", the entire quantity of water or hot water in the bathtub 1 is drained through the drain passage 2. On the other hand, when the first drain valve 3 is "opened" and the second drain valve 4 is "closed", the bath water is applied from the application channel 5 to a washing machine or the like.
