Hi All, First time poster here. I am remodeling my bathroom and have gutted everything to studs and subfloor. When I initially removed the toilet, there was a thick bed of mortar propping up the toilet. I found it strange, but quickly learned it was because the toilet flange was about 1/2” above the finished floor. Well, now I have removed another inch of floor and the toilet flange is 1.5” higher than the subfloor. The new finished floor with be tile on 1/2” cement board, leaving the current flange about 0.75” too high.. How can I lower this thing? The current flange is a female flange that is glued on the outside of the drain pipe. I considered just cutting the flange off and cutting the main drain pipe down and putting in a new flange on the now lower pipe, but everything I’ve read says not to cut into the main drain pipe (not sure how true that is). What are my options? Any ideas on how to lower this thing? Thanks!!
