It depends on what kind of flange you have now. There are two piece replacement flanges that wrap around the pipe and bolt together if you flange is compatible with that type.
: Dear Terry,
: We have remodeled our bathroom related to a slab leak. Our tile guy was laying the last tiles and had to removed the toilet. The toilet flange is cracked and would explain why the toilet wobbles. Terry, is there anything we can do without replacing the flange. We understand this involves pulling up tile and the floor and we don't have the money or patience. Greatly appreciate any suggestion and read the one on toilet flange replacement, I don't know if that is our particular case, ours is out of PVC.
: Thanks so much.
