My son is remodeling the bathroom in his house. He ripped out the toilet and discovered that the original flange was corroded beyond hope. The original toilet sat upon a marble slab which he also removed. He installed ceramic tile right up to the toilet pipe. Now the pipe is sitting about 3/4's to an inch above the ceramic tile. Also, the replacement flange he purchased is too small for the pipe. Now he is out of the state on a work assignment and has asked me to finish his bathroom. The toilet pipe is glue in so I can't just drop it down flush to the floor. I just don't know what to do. I don't want to rip the tile off the floor or cut into the brand new basement ceiling to access the pipe. Can you help me figure out what I should do here?
