What does WC stand for? On a door, a floor plan or an airport sign, WC stands for water closet, an older English name for a small room with a flushing toilet. In plain terms, WC means restroom.
Travelers meet the letters most often in Europe and in international airports, where WC signs are everywhere. In the United States you will see WC on architect drawings, on real estate floor plans and in some restaurants, but in other places the letters can point to workers' compensation, a sports tournament or a writing limit.

What does WC stand for in a bathroom?
In a bathroom setting, the letters mean water closet. The words split like this:
- W, water: the toilet is flushed with water, unlike an outhouse or a chamber pot.
- C, closet: in older English, a closet was any small private room, not just a place for clothes.
The name dates from the period when indoor flush toilets were a new comfort in British homes. The fixture was often tucked into its own tiny room, separate from the sink and tub, and that little room was the water closet. The term traveled, and the short form became an international symbol on signs because many languages could read it.
WC on signs and floor plans
The letters show up in a few everyday places, and the meaning stays the same in each.
Airport arrow: a sign with "WC" next to figures of a man and a woman, plus an arrow left. Follow the arrow to the public restrooms.
- Floor plans: architects label a small room with only a toilet as WC. A "WC" inside a primary bathroom often means the toilet has its own door.
- Home listings: a "half bath" in the US has a toilet and sink. Some listings call a toilet only room a WC.
- Trains and planes: a lit "WC" sign or a small icon tells you the restroom on board.
- Plumbing supply: catalogs may say "WC pan" or "WC seat" for toilet parts.
WC stands for other things too
Away from restrooms, the same letters have several uses. Context usually makes the choice easy.

Saying and writing WC
Say each letter: "double you see." It never gets blended into one spoken word. Write it in capitals. Signs use WC with no periods, while some older British books print W.C. or w.c. "Double you" opens with a consonant sound, so the right article is "a WC." The plural, on a building plan, is WCs.
In US speech, people rarely say "WC" out loud. They say restroom, bathroom or men's room and women's room. If you ask for the WC in an American store, you will probably be understood, but you may get a smile. Read about how initialisms differ from other short forms in acronym vs abbreviation.
