British bathrooms.

[hyperjeff]

Why are British bathrooms marked as WC? What does it stand for?

[rekstout]

It means "water closet" and old fashioned term, no longer in everyday use.

[WaldoMcFroog]

Meaning 'toilet', incidentally.

Not just the UK. The letters are also used here in Belgium (where they are pronounced "way-say") and in France where they are pronounced "doobluh-vay say").

Water Closet it is!

[MikeMikeMike]

It's used pretty much woorld wide now. Although obviously everywhere where English is not normally spoken its a totally meaningless euphemism.

I live in Norway, and when the toilets you could flush first came here, they were called "vann-klosett".

Addition to my previous post: "vann" means water, and I think the word "klosett" is only used in the word "vann-klosett". Some old people still call the toilet by this old name.
