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 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 like as a safety procedure.
