I'm installing a new toilet on a basement floor. I lined up the
flange slots with the bowl holes and traced around the perimeter of
the toilet. When dry-fitted It slightly rocks on the concrete floor.
I can remove small amounts of the concrete with a Dremmel tool. Is
there an easier way than trial-and-error to determine the high points?
How is this usually done? I'm guessing that this rocking has to be
eliminated before I can proceed with the install? TIA

Haven't read all the other posts but I can tell you what I did for a shower
base that had gaps all around it causing it to rock a bit on a concrete
floor. Got a couple of can of expandable foam, you know, the stuff used for
insulating in odd places. Went around the base and sprayed the foam until
it finally started oozing out from under the base. Let it harden over night
and then trimmed to fit. Worked like a charm, the base is rock solid. In
your case don't know what would happen if you ever wanted to lift the toilet
off the floor.
