Many people now refer to the room with the toilet as a bathroom.
However, a bathroom typically used to be a room that had a bath, and this would be completely separate from the toilet.
In a now-deleted TikTok, @itsnathannyc explains: “Before indoor plumbing, we actually had a room for the bathtub, a bathroom. But the spout was outside. You had to carry water in with a bucket, heat it up, pour it in the tub.
“Indoor plumbing comes along and there is already a room with a bath, the bathroom, so where do you put the toilet? Just put it in a closet, it’s the easiest place to put a toilet.”
Due to being one of the only places in the home with running water inside, they later became known as water closets.
“To start, WC is an abbreviation standing for ‘water closet’, a name used in the 1900s for a toilet, due to most being fitted in a spare closet or cupboard. Over time WC has been used instead of bathroom to describe a room with a toilet but no bath,” per Plumb World.
