Inside fit toilet flange over 3” riser pipe

Hi all.

I replaced my bathroom floor, and found the toilet flange to be damaged. I removed it by cutting the top part off flush with my 3” pvc riser. No amount of chiseling is allowing me to remove the remaining section pvc cemented to the pipe.

there is barely any space to work, so I really can’t cut the pipe to replace, so my feeling is that my only remaining approach is to use an inside fit flange. What is your experience using this with a 3” pvc? Will it cut the diameter too much? Or will it likely be fine?

Most toilets have around a 2" trap, so cutting down the 3" pipe a bit shouldn't cause any significant issues in my mind.

In the future, they sell flange repair rings which maybe could have helped before you cut off the whole flange. But no big deal either way, just more work your way.
