Abstract
Abstract A condensation-proof mirror, for use in such high humidity environments as conventional shower stalls or steam baths, has its reflective surface heated by diversion of a portion of shower water or live steam to a manifold on the mirror's rear surface, from which manifold the heated water or steam is distributed across the rear surface, condensing into or flowing into a catch basin or any suitable drain, heating said rear surface by convective transfer from the water or steam, and conducting the heat, so transferred, to the front reflective surface, thereby raising the temperature of that front surface above the condensation temperature for the environment impinging on that surface.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
172 words
In a condensate-proof mirror for use in a shower or steam bath environment and including means for contacting a rear-reflective surface of the mirror with a stream of downwardly flowing shower or steam bath-derived hot fluid for heating of a front reflective mirror surface of the condensate-proof mirror to a temperature higher than that of ambient moisture laden air of the shower or steam bath, the improvement comprising: housing means including utility storage means and a removable open-top catch basin for collecting downwardly flowing hot liquid discharging from a lower end of the rear surface of the mirror, a substantial portion of the open top of said catch basin extending forwardly of the forward surface of the reflective mirror surface wherein hot liquid in said catch basin is readily accessable to a user for purposes attendant showering or steam bathing, and a deflector lip integral with the rear surface of the mirror adjacent the lower end of the rear surface of the mirror for deflecting hot liquid rearwardly into the catch basin.
