I am currios about the gap between the toilet and the tile flooring. I am having about 1/8 inch gap between front of the toilet if I keep the back end tight down flat. But If I keep the front end of the toilet full contact with the tile then I have will have the toilet till forward a little (not level) and it also have 1/8 inch gap between the toilet rear with tile. Here are some pics to my flooring and toilet from Kohler
