So I made the unifit... fit inside the skirt of the toilet as far as it would go and still hold its integrity. I had to drill new bolt locations for the toilet to hold down and change the closet flange bolt pattern too.. I'm certain that I voided the warranty. I was still off by 1/8th of an inch. I also had to flip the tile on the wall around to move the water supply to not obstruct the toilet and fill in the tiny holes where the unifit was drilled into the floor( tile guy did the floor, I did the wall tile without any drywall repair)
this project was done in 2013. So... theres been a bit of water under the bridge as far as the nitty gritty.. but basically i figured out how much I could cut the unifit to keep it functional and fit it back onto the toilet to see where I could cut next. This was not an efficient job.. But it was better than tearing up the finished floor.
