WC, often referred to as 'Water Closet,' is an acronym widely used in architecture and design to denote a room or enclosure containing one or more toilets. The term originated from British English, where 'water closet' was initially used to describe any room with a water supply for washing purposes, but over time it evolved specifically to refer to rooms equipped with plumbing for waste disposal. Today, WC is commonly seen on maps and diagrams in public buildings to indicate the location of restrooms.
