Even when I was growing up (during the Brady Bunch era), people had more than one bathroom. Although, if you think about it, I don't ever recall seeing Mike, Carol, or Alice in the kids' Jack & Jill style bathroom, so I think the house had at least three. We just never saw the parents' or Alice's. I did wonder how Mike could afford to raise all those kids with Carole being a stay-at-home-mom and paying Alice, a live-in housekeeper, on an architect's salary. He must have been far more successful than anyone gave him credit for.
