WC stands for “Water Closet.” Yes, it’s exactly as literal and boring as it sounds. Imagine inventing the flush toilet and deciding the best name is a closet that holds water. Marketing genius.
This term was born in 19th-century England, when indoor plumbing was the hottest new tech. People were so proud of their flushing chambers that they needed a fancy abbreviation—because saying “I’m off to the poo chamber” felt too honest.
Today, you’ll see “WC” on signs from Paris to Bangkok. It’s the international code for “please don’t ask what’s inside, just use it and leave.”
