WC stands for "water closet," which is another term for a toilet. The term originated in the 1900s when most toilets were fitted in a spare closet or cupboard. Over time, WC has been used instead of bathroom to describe a room with a toilet but no bath. A WC suite refers to a complete toilet system, including a cistern, pan, and flush. The toilet or WC pan is the part of the toilet which contains the water and comes in a range of shapes and sizes. Cisterns can either be fitted as exposed or concealed depending on the toilet you choose and the shape and positioning of your bathroom.
