I just noticed that one of the floor tiles on my Princess V72 head shower is loosening up. I’m not sure what they’re made of but they are black hi gloss and are fairly large about a foot by a foot. When I stand on the tile you can see some slight m0tion and moisture being expelling from the seam next to the adjacent tiles I’m wondering if this is something I can repair by lifting up the loose tile, drying the area beneath and then gluing the tile back down. If so any advice on how to handle this And what materials to use ? Or should I leave it to a professi0nal?
