Abstract
A bubbling bathtub system including both a large bubble generator, which blows relatively large bubbles into a bathtub, and a minute bubble generator, which functions so that bath water with air dissolved therein by pressurization is sent to the bathtub to produce minute bubbles in the bath water, connected to the bathtub. The relatively large bubbles produced by the large bubble generator and the minute bubbles produced by the minute bubble generator cooperate to enhance the good feeling produced during bathing. Both or either of the relatively large bubbles and the minute bubbles can be optionally produced as the user desires for optimum effect.
