Our garage had a sliding entry door…one of those good old-house surprises. I wanted to reuse it in the new apartment as the bathroom door. I was told in many ways that it wouldn't work but I knew it would. The hardware was only slightly aged…I just cleaned it and then sealed it with a matte spray…my definition of "pretty" rust.
I started by painting the door with a coat of thinned white paint. It turned a really cool weathered gray but nobody at my house was digging it. I forged ahead and gave it a distressed white finish.
I know I took better pictures of the door but they are nowhere to be found. The top view gives a good idea of it in the space. I'm very happy with it; it adds a lot of charm and architectural interest, allows light into/from the bathroom, and functions perfectly.
