Probably not.

Here's what I did:

1. Tape the mirror up. I put a whole lot on so if it broke, it would go everywhere.

2. Wrap some wire (not thin stuff...about the thickness of the wires that connect to the low keys on a piano) around wood sticks.

3. Slide the wire behind the mirror and start sawing through the glue.

4. Sweat a lot.

5. Mirror breaks and pops off the wall.

Wear gloves! This is a two person job.

You can also call a glass/mirror company to come out, but some will just smash it. My way, I was able to donate the mirror to our Habitat store.

Both of our bathroom mirrors (about 4 ft high x 8 ft long) came off in one piece with two of us just pulling on them. We removed the vanity first so that we could grip them from the bottom and then we just pulled them loose. We didn't even have the good sense to tape them up first but, luckily, they didn't break.

Of course they were just glued to the wall like the one shown above so I can't help you with your question about attached hardware but it does seem strange. Good luck!

Pay a professional to do it. Removing mirrors can be a very dangerous business. We paid a glass company $50 to remove a 5' x 3' mirror and I think it was worth every penny. It took them 15 minutes, nothing broke and sprinkled glass splinters in my bathroom, and they took the darned thing away. Both guys were wearing goggles, "space suits" and what looked like chain mail gloves. When I asked them about the protective gear they said anyone who doesn't protect themselves when dealing with glass removal is a fool. Maybe they were being overly cautious but they were prepared for anything unusual like your situation. HTH.

Thanks for all your help. We will make sure to proceed with caution. This is the first of four baths in this house. Some of the mirrors are 6'x4' so we some serious issues ahead.

We are also updating my mom's house for sale, built in the 60's, all the mirrors have clips and were easy.
