Trope-a-Day: Our Showers Are Different

Our Showers Are Different: Averted, for the most part. Water has enough other uses, starting with radiation shielding, and is prevalent enough in space – and, of course, being built in space, or launched using nuclear pulse drives, there’s plenty of room in the mass budget for the relevant equipment – that most spacecraft and habitats have plenty of water available for real showers. Or even baths (although microgravity baths are relatively small, closed chambers that fill with water, requiring you to use a breathing tube – at least, if you aren’t equipped with those nifty hemocules that let you hold your breath for a couple of hours, anyway.

There are microbot swarms that will clean you quite satisfactorily (a close relative of decontamination mist) without needing water, or indeed requiring you to undress, but those aren’t there because of water-lack; those are there for people in too much of a hurry to enjoy it.

And a “sonic shower”? Well, that’s just a fancy shower-head that helps you scrub.
