> Also your water pressure sucks. That isn't my experience with the top floors of NYC prewar walkups today (and trust me, I've had a lot of that!), but I could see that being an issue in other places or in previous times. I don't think that'd have been a driving factor in ancient Rome, though, given how different their uses of their plumbing technology were from ours. They had public toilets and baths (at ground level), so water pressure for washing and bathing wouldn't be a concern for top-floor apartments the way it would be for us today.
