PROBLEM TO BE SOLVED: To provide a larger relaxation feeling by forming a jetting port to jet hot water in which air bubbles are mixed, into a vertically long, or a laterally long, or diagonally long slit-shape, and performing a jetting of which the stimulation is softer compared with a jetting from a normal circular nozzle. SOLUTION: A suction port 1 and a jetting port 2 are respectively formed into, e.g. a laterally long slit-shape, and they are constituted to be the same, and at the same time, they are operated by alternately switching. That is, in the vicinity of the inlet/outlet of a nozzle, an air intake 3 and a pump 4 are arranged, and at the same time, the suction pot 1 and the jetting port 2 are made to communicate with each other through a circulation path 5. The pump 4 is controlled by a specified mode, and, e.g. under a standard mode, hot water is jetted only from the jetting port 2 located on the back side of a bather, and under a reverse mode, hot water is jetted from the suction port 1 to the breast side of the bather, and in addition, under a mixed mode, the control is performed in a manner to alternately jet hot water from both of the suction port 1 and the jetting port 2. By this constitution, a jetting wherein a stimulation is softer is performed.
