Toilet flange situation

wondering how to remedy a toilet flange situation. sub floor, underlayment, and tile all in place and were cut out around flange (not pipe) when installed so all layers of flooring now have nothing to bolt to and flange just floating. What are some suggestions without tearing out tile and re-cutting flooring???

Anything other than tearing out enough of the old floor to allow filling in with sub flooring, underlayment, tile, and a new flange properly resting on top of the finished floor and anchored to the sub floor will never give you a toilet that you can trust. There might be an exception if the drain pipe, closet bend, and flange are cast iron and you have a plumber install the new flange at the proper height. It may be acceptable for this kind of plumbing to support the entire weight of the toilet. I'm not sure of this, and perhaps HJ or some of the other professional plumbers will chime in on this.

thank you for your response! all piping is cast iron so i was thinking of something to get by. i know it is not the proper way to do it, but i do not want to rip out new tile and flooring.

Any access from underneath at all? A 2-foot square of drywall or even plaster+lathe would be WAY easier to replace than the tile floor. If you can get underneath, you can bridge around the flange.

cast iron

Cast iron pipe and flange is no problem. Crack the flange off, fill in the gap with just a space around the pipe, then call a plumber to install a new flange at the proper height when you finish.
