I am remodeling the bathroom and just completed the demo. The toilet flange was sitting on the tile that I took out. The new tile is too high and cant fit under the flange. But the flange is now higher than the plywood and cant push down so I need to put something only in-between the flange and floor or cut the existing flange and put new one in. I would prefer to not cut the abs to get the flange out. I had the thought of using toilet flange spacers under the flange instead of the traditional above it. Is this a bad idea? The spacer has an option to snap one side off so then I can manuever it into place under the flange so everything is flush with plywood. If this is a bad idea? then any other ideas besides replacing?
