I have a sunroom with ceramic floor tile over a concrete slab. I have two steps down which are not to code. One is 9 inches deep and the second is 10 inches deep to the floor. I would need to raise the existing floor by three inches and one step by one inch to give me the 8 inch drop. Do I need to remove the tile and then build up the existing floor with a self leveling concrete to have a smooth surface? I was not intending to put new tile down but would like a concrete stain.
