I was talking with a plumber that was quoting some work, and he suggested that if I'm installing tile, really it would be better to put my flange on top of the CBU, but level to the top of the tile, instead of on top of the tile. He claimed "it's just very difficult to get a solid base for the flange on top of tile."
Um, *what*???
The way I understand it, first of all floor tiles are pretty big relative to a CF, even 4x4" tiles there would be at most one seam on each quadrant of the flange.
Further more, a flange is not structural, so as long as it's secured relatively solidly, and the toilet is otherwise mounted on a level floor, "rocking" has nothing to do with the flange.
Finally, a lower flange means double wax rings or tall wax rings or other tricks that seem less certain than a single wax ring, and if it leaks, it leaks into the floor instead of on top of the floor.
Is anybody interested in offering a credible viewpoint as to why this licensed professional might have been suggesting this approach???
I'm certain what I intend to do, I'm just terribly curious to either disprove that this is the commonly accepted approach, or find out why that would be, if he was actually right.
thanks...
