A bathroom is a room that may have different functions.
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", "hand basin" or "lavatory", and often a toilet fixture.
The design of a bathroom must account for the use of both hot and cold water, in significant quantities, for cleaning the human body.
A mirror is an object with a surface that has good specular reflection; that is, it is smooth enough to form an image.
The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or demagnified images or focus light or simply distort the reflected image.
Bathroom Mirrors are most commonly used for personal grooming, decoration.
Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery
