Communal showers are a group of single showers put together in one room or area. They are often used in changerooms, schools, prisons, and barracks for personal hygiene. Although the use of communal showers has grown less prevalent in the West in the 21st century than they were in prior years, they are often present in school locker rooms for use in personal hygiene after physical education. They also continue to exist in some gymnasia and at many swimming pools.
