If you can get the mirror off without damaging it, have a way to cut it, and it's a good (non-distorted) mirror, then there's no reason not to reuse it.

Our issue would be removing it in one piece and transporting it to be cut. We're not sure it would be worth the effort for the cost savings.

Remove and replace. For $60 each the cutting and re-framing of the old mirror is sure to be more, and you can sell or give away the old mirror if it survives removal. Blue take the mirror first in a crisscross in case it cracks, so you don't end up with shards all over the bathroom

That's a great suggestion about the tape, tmnca. Thanks!

We had the same size mirror in both our bathrooms. We (DH & I) remodeled the guest bath ourselves, and were terrified of dealing with the mirror! We got it off the wall in one piece and called several recycling and glass companies trying to get rid of it, and no one would deal with that large a piece of glass. So we bought a glass scoring tool with the intention of cutting it into smaller pieces for recycling.

We were totally unable to score or cut the glass! We ended up putting it between layers of plastic drop cloths and hitting it with hammers to break it, and even then it was extremely hard to break.

We asked our GC to do the same thing you are proposing in the master bath. They successfully removed the mirror and his glass and cabinet guys magically made it turn into two beautifully framed mirrors.

I guess my point is that you may need professional, industrial-grade tools to cut the mirror. And if you decide to get rid of it I hope you have better luck finding someone who will haul it away.

If the mirror is up there with mirror clips then you may be able to salvage it. If it is glued, forget it. Trying to cut a mirror with blobs of glue in the back means jagged uneven cuts.
