We have been doing some cosmetic changes to our main bathroom in the last few weeks. New shower curtain and towels, took down a picture and added the two shelves. But the biggest upgrade was adding a frame to the builder-grade mirror that is original to the house (built in the late 1960s). I had seen multiple ads on Instagram from a company called Frame My Mirror. They made it look so simple. Lots of frame choices, glue the ends and hammer in little things to hold the frame together and then take off the industrial tape and just attach it to the mirror.
So I chose a very simple black frame. Their website is very clear about measuring but I had a question about the brackets that were existing. Their customer service was excellent so I placed my order. Our mirror is 5' x 2' so we assembled it on the worktable in the garage. They include little cardboard place markers (not sure what to call them) that you attach to your mirror temporarily so you can make sure the frame is in the right place and level. Then remove the tape and voila. Instant upgrade. Not sure why it took me so long to hit the order button! The light fixture is also original and I have always really liked it--kind of retro. The base was originally chrome and the two round things (also not sure what to call them) were kind of rusty chrome. So I painted them both black and now I'm super happy with the light fixture as well. All that to say, if you are looking to do a mirror upgrade, I highly recommend Frame My Mirror!
