I recently bought a house that has what I believe is an original install Kohler toilet from 1992 or so. It would move at the base, so i tightened the bolts, but I have now confirmed it to be leaking at the bottom flange. I ahve removed the toilet and the tile is up to the flange, but not under it.
After inspecting the bottom of the toilet, I noticed that the toilet drain hole bottom is at the same depth as the base. If I place a level across the base while going over the hole, it touches the center hole in one spot (just barely), and the other side of the center hole is <1 mm probably from the level. So it's not even perfectly flat, but nothing wax will not fix. However, am I incorrect in thinking there should be a gap from the bottom base to the bottom of drain hole?
I'm guessing that is why the flange is below the tile, though its face is only about 1-2 mm from the tile. My question is this: is there a minimum gap needed for a toilet to seal properly? I basically only have 1-2 mm.
