Can I put a frame around a bathroom mirror that is mounted to the wall?
It is a challenge to apply frames directly over a mounted mirror for three reasons:
1) The mirror mounting hardware often extends beyond the edges of the mirror, which would require routing out the back of the frame to accommodate.
2) The depth of the rabbet (the portion of the frame that accommodates the contents) would need to be exactly the thickness of the mounted mirror. If not, then you would either have a frame that did not lie flush with the wall, or a gap between the mirror and the lip of the frame, that would tend to accumulate dust and debris.
3) You would need to ensure that the width of the moulding, which extends out from the edge of the mirror, does not have any obstructions (that you have enough available space to fit the final dimensions- unframed mirrors are often sized to completely fill a space.
It might be easier to simply remove the mirrors from the wall and frame them (if the size is right), or frame another mirror, and then hang the frame conventionally. Framed mirrors are usually beveled for appearance, and are not very expensive, so you may be happier with this approach. Otherwise, I recommend you consult with a general contractor about mounting options in your specific case.
