A bathroom or washroom is a room, typically in a home or other residential building, that contains either a bathtub or a shower (or both). The inclusion of a wash basin is common. In some parts of the world, a toilet is typically included in the bathroom; in others, the toilet is typically given a dedicated room separate from the one allocated for personal hygiene activities. In North American English the word 'bathroom' is sometimes used to refer to any room in a residence that contains a toilet, regardless of the inclusion of a bath or shower.
