A bathroom (also known as a restroom, washroom, toilet or lavatory) is where people go for personal hygiene activities. This includes use of the toilet, wash their hands, brush their teeth, take a bath, or take a shower. The room may also contain a sink, often called a "wash basin", “hair basin” or "hand basin" (in parts of the United States) and often a "lavatory." In the United States, "bathroom" mostly means "a room containing a lavatory." In other countries this is mostly called the "toilet". The word "bathroom" is also used in the United States for a public toilet or "restroom." Bathrooms also have bathroom cabinets.
