Young Blonde Girl Undresses Her Clothes In A Green Bathroom

In the United States, "bathroom" commonly means "a room containing a lavatory". In other countries this is usually called the "toilet" or alternatively "water closet" (WC), lavatory or "loo". The word "bathroom" is also used in the U.S. for a public toilet (the more formal U.S. term being "restroom").
History
Although it was not with hygiene in mind, the first records for the use of baths date back as far as 3000 B.C. At this time water had a strong religious value, being seen as a purifying element for both body and soul, and so it was not uncommon for people to be required to cleanse themselves before entering a sacred area. Baths are recorded as part of a village or town life throughout this period, with a split between steam baths in Europe and America and cold baths in Asia. Communal baths were erected in a distinctly separate area to the living quarters of the village, with a view to preventing evil spirits from entering the domestic quarters of a commune.
