Bath
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A bath (UK English) or bathtub (US English) is a thing people sit in when washing, to wash all their body; the bath is normally in the bathroom. A less common name for a bath is a washtub.
In the UK, a bath is also a place where people can sit in water (or other liquids, often hot) for their health. This is where the town name Bath comes from.
