Imagine water that flowed into drain hole being pumped back into the showerhead.
However, this is the operational principle of dishwashers.

Building off of this, some Japanese households will bathe then towel off and let the next person bathe in the same water and shower off after. Therefore there is a 2 stage cleaning cycle.
I don’t have direct experience so call me out if I heard wrong.
I think before modern plumbing it was quite normal for more people sharing a bath one after the other, or going to large bath houses. The house I grew up in from the early 1900s didn’t have a bathroom and people would handwash and occasionally fill a bath in the kitchen. (We had a shower built in, but it was obviously not part of the original design)
