The sonic shower was a technology that used sonic pulse vibrations to remove dirt, grime, contaminants and possibly dead skin from a humanoid body.

Sonic showers have been in use aboard Federation starships at least as early as the 2250s, and were described as relaxing. High-pitched sonic showers serve a similar effect as to what a "cold shower" serves. The technology was a means to eliminate the need for water used in bathing. However, various Starfleet vessels are still equipped with conventional water dispensing hygiene applications such as a shower or a bath tub.

Although the technology was generally considered very effective, it did have limits on certain applications.
