“WC” on bathroom signs stands for “Water Closet,” an old term for a toilet room. Common in airports and hotels, it confuses many.
A 2020 TikTok by Shelby and Dylan joked about terms like “washroom” and “restroom,” asking if anyone really rests or washes in them.
The video went viral as people shared their preferred terms—bathroom, washroom, toilet, or WC. Historically, “Water Closet” referred to a room just for the toilet when bathing was done separately.
As indoor plumbing spread in the 19th and 20th centuries, WC became a global label, especially for travelers.
Reddit users have debated the term, with some puzzled by the “closet” part and others sharing international variations, like Russia’s “room without windows.” In Canada, “washroom” is popular; in the U.S., it’s usually “bathroom” or “restroom,” depending on the region. Whatever term you use, they all describe the same place.
