CONSTITUTION:The main unit 40 is disposed between the washing area and bath tub, and a sub unit as a bath tub setting unit 41 is disposed near to the bath tub 33, and a sub unit as a shower setting unit 42 is disposed near to the attachment of a shower 39. In the space between the bath unit 43 and the wall 44, a valve unit 19 is disposed as well as a control unit 45 to which the setting units 40, 41, 42 are connected parallel. When the washing area switch 66 in the main unit 40 is pressed, hot water supply is started at the temperature and flow rate set in advance with a kitchen remote controller 46. This is executed as a control valve 26 opens the flow passage by a command from the control unit 45, and a control valve 30 selects a faucet 38 in the washing area. The hot water supply temperature is controlled by regulating the mixture ratio of hot water and cold water so that the preset temperature is obtained.
