Thanks for the thought, HJ. I will make a point of having a tile cutter on hand just in case.
Recently, when the toilet was pulled away for a flange replacement, I wasn't seeing the tile extending into the opening. I will definitely look at that possibity again in a week or two when the toilet gets replaced.
Another possibility that is occurring to me now that you bring up the tile, is the floor bolts may play a role in having been placed >12" from the wall.
I have a feeling it may be the bolts placement in the tile below. I'll let you know in a few weeks.
In addition to the tile cutter, I suppose I should / will get several replacement tiles and associated materials now.
HJ, thanks so much for responding. When something isn't visually correct, I can't ignore it.
Would a plumber correct the "tile" problem as part of toilet removal and installation of a new toilet?
Or, should I get a tiler?
Any idea how much time is involved with such repairs?
Either way, The toilet is secured to the floor with thin-set because the floor bolts were rusted and cut to floor level by a recent plumber. I think I need to start trying to remove all the thin-set while waiting for the toilet to be available.
