Every light colored wall and ceiling can be thought of as a potential reflecting surface. Light strikes the surface and bounces deeper into the space. When a window, skylight, or light fixture is located directly adjacent to a perpendicular wall or ceiling, it’s as though the surface becomes part of the light source, reflecting the maximum amount of light available into the living space. Two different types of reflecting surface can help make a bathroom seem more spacious than it actually is. A mirror can appear to double limited space, while a window or skylight that’s located immediately adjacent to a perpendicular wall can fill the room with light, increasing the perceived size still further.
