I am installing a new ceramic tile floor in a bathroom. This raises the floor by about 5/8 inch. Is there an extension I can add to the toliet bowl or floor flange to make up for the added distance the wax seal must extend?
Ask for a “jumbo” wax ring at the plumbing supply store. It is thicker and has 50% more wax to compensate for the added thickness of the tile.
Also, as a sideline, make sure the metal flange ring that holds the bolts that secure the toliet bowl are tight. I had to reset the ring with concrete anchors to the foundation because the orignal was only put in place with 1″ nails.
