Abstract

A non-foggable mirror assembly for use in a shower comprises a mirror mounted on a unitary frame. The frame is recessed to provide a space between the back surface of the mirror and the frame. This space serves as a chamber for hot water, which is fed through a port at the bottom of the chamber, and which exits through a continuously open port at the top of the chamber. The bottom port is connected to an adapter for connection to a water pipe leading to a shower head for tapping off heated water. The heated water passes upwardly through the chamber continuously, heating the mirror, and preventing condensation.
