> I seem to remember that Roman toilets were often in the kitchen...

Not unusual for buildings in Europe or the US built around the turn of the last century either.

These days, they're typically renovated so that there's a wall in between and the bathroom door leads off of an incredibly narrow kitchen, but a hundred years ago, those were in the same room.

(And those were the ones who were lucky, because they actually had a private bathroom).

And a private kitchen!!
