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.

    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)
