  • Bubbling bathtub system
    Patent number: 4907305

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.
