Toilet Flange Replacement

[LoneStar]

I cut the top flange portion off my original 1981 toilet flange because it was 3/4” above my finished floor and slightly warped. As shown in the pics it’s flush with my subfloor now. The collar portion of the flange still remains. I purchased a few flanges from the big box store one designed to go over the 4” pipe but surprisingly it was too big. Would greatly appreciate any advice on how to proceed. I have an oscillating tool to make a cut ‘below grade’ and then try to remove the entire collar but wanted to check with the experts first!

That is a not-normal looking pipe thickness.

What’s being measured is the remaining portion of the flange.

Install an insert flange.one that goes inside 3" pipe. I would say you can cut the pipe down internally and glue a coupling on but I'm afraid you are to close between the flange hub and 90 hub and would not have enough pipe to glue to.

The pipe is still inside the hub of the old flange. You can make slits in the old hub and try to peel it off and glue a new flange on, or find one that fits inside 3" pipe

I see a crack at 5oclock.... the flange is supposed to sit on the finished floor not the subfloor so make sure it has space for the flooring or install it last.

Yes, I got a little aggressive with the hack saw blade. Thanks for the tip on placement.
