I am in the process of tiling my bathroom, now that I have the 12 X 12 tiles on the floor and nearly done with them, I need to do the walls behind the toilet sink and cabinet. My question is, how far do I have to move the toilet flange (pipe) forward so the new tiles will not interfere. The toilet sits right on the wall. I used 1/2 backerboard, and I am using a 4x4 tile and thinset to mix and hold it together.
tricky aspect. look with google. this could help!
based on what I've read, I don't understand why you think you need to move the toilet flange to tile?
if you put the backerboard over you existing wall (1/2') and you're going to tile that, (1/4'), and you should have 1/2' space between wall and tank top...then you need an additional 1 1/4''. Obviously you will have to add length to your pipe also.
If you removed the drywall and installed the cement board then add the thickness of the tile plus 1/4 inch for the thin set. If you put the cement board over the drywall then and in the 1/2 inch into your total. It's not a bad idea to give it a little extra room behind the toilet. You don't really want the tank right up against the tiles anyway. All it takes is somebody to lean back on that tank and crack a tile .Give it an extra 1/4 inch. Bottom line the toilet flange should be 12 inches from the finished wall by code. Don't forget to use a thicker wax ring or a flange extension when you reset that toilet to make up the difference of the cement board and tile.
