Hi, I have a question about replacing a couple tiles in a shower enclosure. I'll give you a quick rundown of what we're looking at: (Background: shower spigot and single handle controller are on west wall; door is on north side; south and east are tiled; one piece floor drain assembly; 7 years old). - Noticed crack in tile on bottom of south wall, next to southeast seam (this is the area that gets most water during showering). - Removed cracked tile; found mildew; removed surrounding tiles until I found all mildew; removed mildew with bleach; removed 2.5 tiles total. - Some of the green paper part came off with the tiles. - Southeast bottom corner is where tile was removed. Backerboard was soaked through in one spot in the corner--removed pieces of green board that were falling out. Now have a small 'hollow' spot in the bottom southeast corner. Hollow spot is less than 10 sq. in. total (much less than the tile that covered it). Question: Can I fill in this hollow spot? If so, what should I use that would be most resistant to expansion/compression? If not, how should I proceed? Since this is the spot that gets the most water during showering, I want to make sure I fill it in as best I can without having to take out all the tile and replace the backerboard. Let me know if I can give you more information. Hopefully I have given you enough info to get a picture of what it looks like! Thanks in advance for your expertise! Jeff

How do I compensate for a tilted tub when tiling the wall above the tub? If I follow the manufacturer's instructions and make the first row of tile level, I will have an inch gap below tile at the front of the tub along the outside wall.
