Have you ever seen the letters WC on a sign outside a public restroom and thought about what they stand for?
Many people are puzzled by the term “WC,” which stands for “water closet.” It’s simply another name for a room with a toilet and a sink—but the meaning can still feel confusing! In 2020, a TikTok video by a couple named Shelby and Dylan went viral after they joked about the many names for this everyday space. “What are they cleaning in there? It’s just a bathroom,” Dylan said, while Shelby added, “Do you rest in a restroom?” Their lighthearted exchange sparked an online debate about which term makes the most sense.
The phrase “water closet” dates back to the 1800s, when indoor toilets were rare and usually placed in a small separate room from the bath. Over time, as plumbing improved, the bathroom began combining the tub, sink, and toilet into one space. Today, “WC” remains a common label in airports, hotels, and public places—especially in Europe.
From “bathroom” to “restroom,” “washroom,” or “loo,” each term reflects history, culture, and humor. So—what do you call it?
