Public toilets can be referred to by many different names. Some common synonyms include restroom, washroom, lavatory, bathroom, comfort station, powder room, and WC (short for water closet). Other regional variations include loo (in the UK), john (in the US), and dunny (in Australia). Certain places such as airports, train stations, and malls may have their own terminology, such as airport facilities or station conveniences. However, regardless of what they are called, public toilets are an essential aspect of modern society and play an important role in maintaining proper hygiene and sanitation.
