Imagine water that flowed into drain hole being pumped back into the showerhead.

However, this is the operational principle of dishwashers.

E: I was hit by this thought after watching Alec’s* ramble on dishwasher detergents.

    Honestly, with a fresh-water rinse I could easily see that being beneficial.

    Consider:

    1. particle filters (or other cleaning steps)
    2. custom water treatment like a bath
    3. not just water, but recirculated heat as well
    4. better possible water pressure (weak well pump), heat control

    Maybe even the type of thing that could run off of solar or backup power for a planned shower.

    Though yeah, I guess a bath (with a quick shower after) probably is a whole lot cheaper and easier to (plumb rather than) engineer. Plastic tubs have their own grossness, though.

    I also imagine this fitting more as some sci-fi thing, not sure how well it’d be easy to manage water in space, though. My first thought would be people annoyed with having to vacuum up droplets, get blasted with air, or being stuck in a drying room as a safety procedure. And some sci-fi vat bath might still make more sense.
