Floor mirror

There are a few ways you could do this.

First would be to use adhesive specifically for glass and mirrors (Liquid Nails has a product just for mirrors). Just do a bead of the adhesive along the inside of the frame or the edge of the mirror. The only thing to worry about is getting it too close to the edge of the frame, where you'd be able to see it in the mirror.

Secondly, you could route out a "notch" in the frame and assemble the frame around it.

Finally, you could use mirror clips. These are the easiest solution, however the mirror will "wobble" when you go to wipe it.

Thank you for the info. I will check out these options.
