Bathroom remodeling

[fugazi48]

removing the tile will probably destroy the paper of the drywall. I had this problem in a smalls section of my bathroom. I was able to hid it with paint and drywall compound, but I don’t think your glue will work well on a crumbly drywall surface. If you go though the trouble of removing the tile, I would replace the drywall with greenboard or backerboard.
I am not a pro though.

The people in my house before me put the enclosure on to of the tile, which worked out well when we has a little bit of leakin at the seams. The tile kept that from destroying the walls.
