Removed Toto one-piece toilet to find the flange kit was off center. In addition the flange was over 1/2” below the finished tile. I cut away tile for flange spacers to be installed. Spacers were installed with 100% silicone applied to seal them. The spacers were screwed to the subfloor through the original flange. A new wax ring was set, the flange kit was centered and new holes were drilled to secure it to the subfloor as well. Once secured I ran water from the fill valve to test for leaks. The toilet was then reset, supply line was connected and the unit was tested for proper operation. Client flushed it a couple of times until satisfied.
