Floor Repair Under Toilet

This picture below is looking up at the basement ceiling where the upstairs toilet had leaked.  The photo was taken after I cut out the rotted wood in the square shape you see.  The toilet had leaked for such a long time there was no wood left to support the pipe flange.  The toilet was sitting on a wax ring on the pipe with some support from the tile floor.  A trip to Home Depot was in order for some Minwax epoxy wood fill, Loctite construction glue, and plywood.
