Great info. I've never had to do a template before but I probably should have at least once. I can remember needing 3 wax rings on one toilet and still having to caulk around the base to seal it up so the gas smell would seep in when the barometric pressure changed outside.
Wow! A triple-decker! :-) I was pretty bummed when I found out I had to do the riser, but it was one of those things I just had to do... too many people watching! Hahahaha!! Thanks @qberry, see ya around!
