Falling mirror
 

Always always put clips or other support at bottom of mirror to support weight. Mirror mastic will hold mirror to wall but usually will fail if weight not supported. Believe me I had two fall one after a couple weeks and one that was professionally installed after 15 years that did have bottom support minutes after our granddaughter left the room.

I have removed from both bathrooms. Yes, there was damage but with some retextured/painted walls, you’d never know.
I need my bathroom cabinets raised so they had to come off.
Much more modern and love it. Bought the mirrors at Home Goods.
I used Steve Kling painting. Sorry I don’t have the number.

:) If you reread my post, you will see I agreed with Kahuna32162 about CENTRAL FLORIDA KITCHEN and BATH being a great company to work with. Omar is the owner. They have a Web Site.

I removed ours. I taped grid patter and used shims to pry slowly off wall. It ripped holes in drywall where big globs of glue were used to attach mirror as they don't use mirror clips. Takes time to not break mirror.

Lots of good advice on removal of mirror. One thing not being talked about is the disposal of the mirror. You will not be able to leave it out for regular garbage pick up or the special pick up for larger items. I took a glass cutter and scored the mirrors in half to make it easier to handle and so they would fit in the back of my CRV and took them to the Sumter County Solid Waste Citizen Drop off Area at 819 CR 529, Lake Panasoffkee, FL 33538. Phone 352-689-4400.

Good Luck as they are heavy and awkward. I used a suction cup handle which made it a lot easier to handle. Put the handle on the mirror side, it will stick better. Back side of mirror it did not want to hold as well.

Another trick to try
 

On Hometalk.com, a DIY site, they have shown the installation of narrow (12" wide?) counter-to-mirror-height shelving midway across the width of the huge mirror. That gives extra bathroom storage as an additional perk. On DIY projects where they remove the mirror instead, they also strongly recommend taping it up to avoid breakage or injury during the process).

On another note, one of our builder installed mirrors slid part way down behind the vanity (i.e. it had no mirror clips on the underside) after more than 10+ years and we had to call a handyman. I have also noticed (because we painted a darker color over the previously white room color) that the double width mirror in the MBA was also inching down gradually over time. Each year I needed to touch up paint all the way across the top. Finally had a handyman fix it too!
