PROBLEM TO BE SOLVED: To provide a jet bath system capable of suppressing power consumption by dispensing with large torque when changing over a channel by a selector valve. SOLUTION: This jet bath system is provided with a control part for controlling a pump, a selector valve, a solenoid valve, and is characterized in that, when changing over a mode from a second mode where a jet flow in a state being mixed with air bubbles is jetted out from a second nozzle, to a first mode where a jet flow in a state being unmixed with air bubbles is jetted out from a first nozzle, the control part reduces the rotation speed of the pump or stops the pump, thereafter closes the solenoid valve, changes over the selector valve to communicate a first jet supply system to the pump and, after changing over the solenoid valve and the selector valve, actuates the pump with its rotation speed increasing to a predetermined rotation speed.
