One of the big tasks for our bathroom remodel was to remove the 108 inch mirror from over the vanity. There are other ways to accomplish this, but this is how a retired glazier did it.

And, I cut down the mirror to reuse as two new framed mirrors!!

Caution: If you choose this method, you need at least 3 to 4 people and unlike me, you should wear safety goggles and cut level 3 gloves. And make sure you know how to use your suction cups safely!
