Rather than contribute to the volume of junk in the local landfill, I opted for replacing the frame. I took the chest out of the wall and disassembled the mirror from the metal box. It was held there by about two dozen screws.

The metal box needed a bit of light sanding and a quick spray paint job. The mirror was in perfect shape and really was a very nice piece of electroplated glass. Probably cannot buy one this nice any more.

The replacement frame was made with mitered corners from standard poplar purchased at Lowes. I bought a European-style narrow profile vanity from the local box store. It had what the manufacturer called a Cherry finish. Trying to match that color required testing several different stains on scraps of the poplar. The final choice was one by Cabot called Red Hickory. I put one coat of the stain on followed by one coat of satin polyurethane. A light pass with fine steel wool followed by another coat of finish was all it needed to match the finish of the vanity.

Total cost of the project: $20. Compare that to at least $100 for a new medicine chest. Love it.
