Hello, New here and I need some help. Actually my mother needs help, but I need your help before I can help her. The Toilet above her bedroom flooded the other day and quite a bit of water leaked down through her tiled ceiling into her room. So her ceiling is trashed and I would like to attempt to fix it. Although I have never done anything like this, she does not have the money to call someone to fix it. I've enclosed some pictures. From what you see can I just go buy some 12" tiles and put them up? How hard is it to put those up? I tore some down and it seemed simple enough, but things always seem that way till you get in there and get your hands dirty. I tried looking for websites with pictures or directions/instruction, but found nothing. Well here are the pictures. Sorry for pictures sizes, it wouldn't let me post a link to smaller thumbnails. So is it possible for me (someone who's never done this kinda stuff before) to fix that without calling a professional? Thank you very much for your help.
