To provide a bath system enabling a cooperative operation of an automatic drain plug and a water heater when communication standards used by the automatic drain plug and the water heater differ from each other.SOLUTION: A bath system includes: a remote controller that instructs a water heater to execute a hot water filling operation; and a control unit that controls an operation of an automatic drain plug. The remote controller includes a remote controller side HA terminal, and the control unit includes a control unit side HA terminal. Each of the HA terminals includes: a control signal pin for communicating a control signal serving as operation instruction information on the hot water filling operation; and a monitor signal pin for communicating a monitor signal serving as execution information on the hot water filling operation. By using communication cables, the control signal pins are connected with each other and the monitor signal pins are connected to each other. The control unit side HA terminal is the controller side on which a photo coupler is disposed. When receiving the monitor signal serving as the execution information on the hot water filling operation from the remote controller through the HA terminal, the control unit performs control so as to close the automatic drain plug.SELECTED DRAWING: Figure 1
