    Default Toto Supreme - Toilet Flange Height

    Hello, my name is Dan… First time post, been lurking for a little while (and learned about Toto here).

    Just tiles the master bath and getting ready to raise flange and install toilet.
    My reading tells me the consensus (albeit still contentious) is to set the bottom of the 4x3 flange flush with the FF/tile, so the top of the flange is ~1/4” above FF.

    I’ll be using a no funnel/horn wax ring (jumbo, I think). I don’t like the twist-n-set as it reduces the ID to 2-1/2”, so my current plan is to use 2 1/2" spacers with glue-sealant.
    1.) Well, I’m looking at the Supreme horn and it’s flush to the bottom/base. Wouldn’t the horn then be sitting on the flange and (might possibly) rock the toilet?
    2.) Doesn’t the toilet-horn/flange need some gap to compress the wax ring?
    3.) There is a slight ~1/.8” skew front to back, higher in the front. Is this a problem?

    The horn drops into the flange.

    having the top of the flange 1/4" above finish floor will work fine.
