A fogless shower mirror includes a mirror assembly having an elongated hollow body which has a thin, rectangular-shaped mirror frame section on which is mounted a mirror plate, and an upper rearwardly curved water supply conduit section. A rectangular slab-shaped reservoir within the mirror frame communicates at the upper end thereof with a bore through the water supply conduit, which has at an outer end thereof a vertically disposed water fill aperture. The reservoir and water supply conduit are filled with warm water, and the mirror assembly is releasably attached to a mirror support stand attached to a shower enclosure wall. The mirror plate is heated by the warm water in the reservoir to thus resist fogging caused by condensation of water vapor, Water cooled by warming the mirror plate trickles from a small drain hole in the reservoir and is replenished with warm water from the water supply conduit.
