An automatically filling fogless shower mirror includes a mirror assembly having a mirror which thermally conductively contacts a water reservoir within the mirror assembly that communicates at the upper end thereof with a water-fill aperture. A tubular automatic water-filling adapter installable between a water supply pipe and a shower head has protruding from the adapter a flexible water supply tube which diverts a small portion of water flowing through the adapter into an inlet opening of the tube, which is discharged from an outlet opening in a distal end of the tube which is removably inserted into the water-fill aperture. Heating of the mirror by warm water in the reservoir prevents fogging caused by condensation of water vapor. Water cooled by warming the mirror trickles from a small drain hole in the reservoir and is continuously replenished by warm water supplied by the automatic water-filling adapter.
