installing tile. Toilet against the wall
Depending on exactly how the flange is set, you MIGHT be able to pull the toilet, tile, and reset it 1/4" forward of where it was. The flange bolts fit into slots in the flange, and it just depends on their current position. To determine if it'll work, carefully lift the bowl straight up and take note of exactly where the bolts are in the slots...See if you can move it 1/4" and still be securely in the slots. You'll need to set a new wax ring when you do this.
