Need help for raising level of tile for concrete slab.
I am remodeling a bathroom in my 23 year old condo. I am on the ground floor on a concrete slab. So far I have completely removed the old tile and thinset with a chipping hammer the concrete is nice and smooth. Toilet is removed as well with just the flange showing. The problem I used to have was that the toilet was pretty much sitting right on the flange and could rock back and forth a very slight amount (maybe 1/16” or 1/8”). So the flange is too high. My options are to lower the flange or raise the floor. Replacing the flange is too difficult for me.
Now the old floor was just ceramic tile on the concrete and had no cracks in it. The concrete also has no cracks or moisture issues. What are my options for raising the floor? Cement board, Ditra, just a thick layer of thinset + backbuttering? I’m not sure which is the best and cost effective solution. Thanks!
