Tile repair under toilet
One of my pair of four year old knucleheads decided to test the capacity of one of our toilets using the old washcloth down the hatch trick.
Toilet now flushed sluggishly, but still drained as did all the other drains. One morning my shower began to fill up with water while showering. I plunged the drain vigorously and it drained fine. Nonetheless, I removed the toilet and could not see the rag. Still decided to call in some backup.
Roto-Rooter inspected the drain with a scope and could not find the rag. He said it may have been pushed out to the main. I got a horn-type wax ring and set of brass closet bolts from him, though for putting the toilet back.
Anyway, as I started to replace the toilet, I noticed some of the tiles were loose, and the mortar (sp-?) underneath the broken tiles where the toilet used to be appeared damp and soft. *Uh-oh*, I thought. "I better get on GardenWeb before I try and put this puppy back, and find out what to do."
How do you do small-area tile repairs like this? All the videos and how-to's I Googled were focused on how to tile your whole bathroom, which I AM NOT trying to do right now.
