When I was really young, I remember going to my great aunt's house. She lived in an old neighbourhood, in a house that was originally built in the 19th Century.
Her house had a cellar with a dirt floor. The house had a furnace in a room, but there was no duct work, so the furnace just heated the entire house based upon dispersion of the heat.
The bathroom, with bathtub, toilet and sink, was an addition onto the house. It did not get much heat at all.
I learned later that many people did not have bathrooms in their houses here in the 19th and early 20th Centuries. They had outhouses in their back yards. They went to bath houses to bathe.

An old public bath house was converted into upscale condos in the mid-90s. That neighbourhood has art walks monthly. During one art walk, I explored the ruins of the old bath house, prior to the renovation, along with some friends. We haven't toured the condos since they've been built. That same neighbourhood is where St Theodosius Russian Orthodox Cathedral is located. That was the church where the wedding scene in
The Deer Hunter was filmed.
