I want to purchase two 1/4” mirrors in a custom size so that they are the width of my sink, but the height of the vanity to ceiling space. I’d like these to appear to float. Once hung, you would see the left and right sides of both mirrors. I do not want to use clips for install. Can any pro help me understand the steps? Should I just use mirror adhesive on the backs? Or, am I supposed to mount the mirrors on plywood or something first? And if yes to the plywood, how do you hang that on the wall? I think my mirrors will be 26 x 56 approximately. I may make them skinnier, say 20, but I am trying to cover a few drywall issues with the mirrors. This is a master double sink vanity that is 8’ wide and beautiful. Thank you for any detailed steps you can provide. I’d like to order my mirrors online as soon as possible.
