I am replacing the existing tile floor on a concrete slab in my powder room with new tile. I pulled the toilet and found the pvc flange was almost flush with the tile, 1 wax ring was used; it was tiled around the flange. The flange is primed/glued on the outside of the 3" pipe. It is NOT screwed into the slab and the front and back of the flange is solidly sitting on mortar. The sides of the flange (were the brass bolts go, is void by about 1/2").
My new tile is slightly thicker than the tile I am replacing and therefore the flange will likely recess 1/8 - 1/4" below the new tile if I tile around the flange.
I had originally planned to cut the flange off with an inside pipe cutter and put a new flange sitting on top of the tile.
Cutting and installing a new flange looks like a bear of a job, I can cut the top of the flange, but don't see how I can easily remove the portion of the flange primed and glued around the outside of the 3" pipe. Plus looks like i need to chip out a lot of concrete around the pipe.
I did notice one side of the flange has a crack on the outside lip where the closet bolt was sitting.
Looking for some guidance:
A: Leave the flange as is, tile around it, try to screw it into the concrete, and use thicker wax ring.
B: Remove the flange (How do I remove the portion glued to the 3" pipe?), prime and glue a new flange in place above finished tile floor. I saw the Twist-N-Set Flanges, but that goes inside the 3" pipe making the diameter smaller.\
