A bathroom is a room that may have different functions depending on the cultural context. In the most literal sense, the word bathroom means "a room with a bath". Because the traditional bathtubs have partly made way for modern showers, including steam showers, the more general definition is "a room where one bathes". There can be just a shower, just a bathtub or both; and often both plumbing fixtures are combined in the bathtub. The room may also contain a sink, often called a "wash basin" or "hand basin" (in parts of the USA) and often a "lavatory".
