Re: What about regular showers?

I don´t think a sonic shower is realistic at all. The sound pressure needed to remove anything that sticks to your skin would be pretty great and if not unhealthy then at least unpleasant.
Dentists have been using ultrasonic devices to clean teeth for decades, but skin is way softer and more sensitive than tooth enamel.

There's an old thread on this topic. The original idea behind a "sonic shower" is that it minimizes water use, not that it uses no water at all.
