Although the standard perception of a mirror is one sitting over a wash basin, mirrors in the last twenty years or so have very much come into their own. Designers and architects often use mirrors as a focal point, be it in a gymnasium or a hotel lobby.
The use of mirrors can offer very subtle effects to a room such as adding light to an otherwise darkened area of a room, giving the impression of expanding the room size. Wall to wall mirrors can give the illusion of a spacious environment or simply provide a unique backdrop to a focal point or object.
