PROBLEM TO BE SOLVED: To constitute one bathtub water circulating, filtering and heating device by making a circulating supply passage of bathtub hot water, which is supplied to a plurality of bathtubs having different sizes or arranged at different levels common and to control the hot water temperature of each of the bathtubs to an arbitrary proper temperature and a proper hot water level. SOLUTION: In the bathtub water circulating, filtering and heating device of two bathtubs arranged at different positions, flowing water amount adjusting means comprising adjusting valves 15 and 28 and check valves 16 and 17 are provided to the discharge pipelines of bathtubs 26 and 1 at two different places and the pipelines are combined to arrange a hair catcher 2, a filter pump 3 and a filter device 4 and, further, a replenishing water pipeline having a replenishing water valve 11 is connected and a heating pipeline having a bypass pipeline and a heater 5 is formed by a hot water temperature three-way valve 13 and the pipelines are further combined to provide a temperature sensor 9 and the pipeline is further branched to form bathtub pipelines at two places and a falling water preventing solenoid valve 29 is provided to the low place bathtub pipeline and hot water level control means for controlling hot water levels on the basis of hot water surface level meters are arranged to both of the low place bathtub pipeline and other high place bathtub pipeline and these are controlled by an attached control panel 14 to control a hot water level and hot water temperature.
