As I understand it, since atleast TMP Era, starships were equiped with Sonic Showers . . . so much so, that they appear to be common place even on planet side installations.
However, I must wonder, are water based bathing facilities (two different links) still available? And if so, to what extent?
I can understand the reduction of operational/engineering maintanance that is caused by removing a plumbing system from a Starship . . . and planetside . . . this would be even greater (although a plumbing system would still be necessary due to other then bathing uses (industrial, cooking, gardening)). But you would think that a certain percentage of the population would still favor water based bathing (and some other species . . . may use powder based (like chinchilas do), or what have you). And if so . . . would it still be possible to have it. Or even on a Starship. Can you imagine an Admiral's quarters, or another VIP's quarters, being equiped with a water hygiene system . . . or whatever that species norm is.
