I replaced my old toilet years ago and the new toilet never did sit flush on the floor. It sat up about 3/8" and I had to shim and caulk it. The flange sits up, its not flush on the floor like the newer houses I've seen. I want to install a new toilet but I would like the toilet to sit flush on the floor, not rock on the flange. It just seemed like my original toilet was larger underneath than the new one. My question is this, are all toilets standard as far as the height-to-flange is concerned and the width of the underside toilet to fit the flange? The original toilet (square in the front) sat flush, put the replacement (round in the front) didnt. The house was built in 1956 and the flange is big cast iron and has a big lip. Is the toilet flange to big (diameter) for the new toilets. Are the new toilets they are making now days not made to fit well on the old cast iron flanges. Any ideas? Thanks
