I live in a 3/1 in the US, and having a 2nd bathroom was on our list, but when it comes down to it, we all end up sacrificing something. As you mention, an en suite master bathroom would be incredibly nice, and if we remodel, it's _the_ #1 non-negotiable item on the list. Private bathroom for us, 'clean'/separate bathroom for guests/visitors. My sister lived in a 4/1 with an odd feature: a toilet on a wooden pedestal in the (full-size) basement. No wall around it, not even a curtain. Just sitting there in a corner. As she put it "you only need it every once in awhile, but when you need that second toilet, you're REALLY GLAD you have it! I don't find the proliferation of bathrooms/toilets in large houses surprising at all. If I lived in a 4000-5000sqft mansion, I might not mind a 2-3 minute walk to get to my bedroom at night, but I sure as hell don't want to have to do so every time I have to use the facilities. It simply makes sense to have a toilet and sink, at least, near the rooms you use regularly.
