The air bubble generating bath A having the above-mentioned functions is provided with a bathtub main body 1 installed in a bathroom R, a motor 9, a pump unit 6,
The control unit 10 and the attached devices are disposed outside the bathroom R as the outdoor device a.

Therefore, the jet pipe 5, the water absorption pipe 8, the wiring, etc. between the bathtub body 1 and the outdoor device a penetrate the wall W between the bathroom R and the outdoor.

With the above configuration, the bath water in the bathtub body 1 is circulated by the motor 9 and the pump unit 6, and the bathwater containing air bubbles is jetted out of the jet nozzles 2, 3, 4 into the bathtub body 1. By stimulating the bather, the recovery from fatigue, the therapeutic effect and the enjoyment of bathing can be increased.

In order to support the bubble generating bathtub A on the floor surface r of the bathroom R, legs 17 are respectively provided at four corners of the outer bottom surface 16 of the bathtub body 1 so as to project integrally with the bathtub body 1.

As shown in FIGS. 4 and 5, the leg 17 is formed in a tapered shape that gradually becomes narrower from the upper end to the lower end of the leg 17, and the outer peripheral surface of the leg 17 is formed. To
A plurality of vertical ridges 18 are formed, and the cross section of the leg 17 is formed in a substantially star shape.

The leg 17 has a bottomed cylindrical anti-vibration support rubber 20.
