Well, for one thing, couples who have children would have a roomy place to just be. Their children would be in the rest of the house, doing whatever it is that they do.
What I don't understand, is just how big should a bathroom be?! I've cleaned houses where the bathroom in the master was as big or bigger than my bedroom! In one, there was a tub, a separate shower, toilet, a bench, a couch. I don't know about spending all that time in a bathroom! i guess if I were rich, I'd have one at least with a steam room and a hot tub.
