Rotted 2nd level floor beneath Toilet
Thanks for the help...
When chipping the old tile out I discovered that the floor was rotten all around the toilet. Infact it was the tile that held itself up. It went through the celing of the room under it.
Further inspections showed that the flooring under the cast iron tub was rotting out and the tub was just about to rust out.
In short, the weekend project turned into a 3 month nightmare. Rotting joists, rotting/mildewed drywall in the walls the whole thing. Working late nights and weekends I got it done.
Best case for you, just replace the floor around the toilet and re-level the ****er out. Worst case call a contractor....
