my upstairs toilet started to leak (water was leaking out of lights on ground floor), so i pulled it up and it looks like i need to re-install some octagonal tile; put on a new wax ring an then re-seat the toilet. the toilet had been rocking side to side, but i'm not sure exactly where the water was coming out of, but it looks like it just needs a reinstall.
but...
when the toilet was installed whomever installed it cracked up some old tile to fill in the voids around the octagonal tile and the round flange. it looks like he just adhered those pieces in a bed of tile adhesive or grout ontop of some substrate.. the top of the flange is about 1/4 inch higher than the floor.
rather than try to piece together what was there, i thought i'd relay the tile and then fill in the void with something like Bondo (fiberglass resin autobody filler). the stuff hardens quickly and can be made level with just a putty knife. i'd say there are areas of up to 1" between the edge of the tile and the flange.
good idea or is there something else i should consider? thanks in advance
