For what does WC stand? You may call the restroom “bathroom” or “restroom” if you’re feeling really refined. My brain is spinning since it turns out we called it something else before. The letters “WC” on a bathroom door really signify something; they stand for “water closet.”
The fact that there is a reasonable explanation for it just makes matters worse. Going to the restroom used to mean you were going to take a long, hot bath. It was expected that people would use the bathroom’s basin and mirror to unwind or get ready for the day. You would use the restroom in the water closet if you really needed to relieve yourself.
