I have a large framed bathroom mirror (72x42") and I would like to take it off the frame and make this a floating mirror on some kind of mounts. I thought this would be relatively easy, but I can not find out how this type of mirror is mounted. My hardware stores have not been any help and I can't find this type of hardware online. There are a lot of companies selling floating mirrors, but they are secretive about their hardware. I have found some very nice visible supports by Vola and Dornbracht, but I would prefer to have mounts hidden on the back somehow. I am sure there is an easy answer, but I need help.
