Trying to figure out what to do with my yet to be purchased marble threshold.
What is the minimum/maximum and optimal height that the top of the threshold should be above the tile?
How much height should I allow for the thinset etc.?
Option #1 = Ditra with tile: 1/4" nominal tile thickness + 1/8" Ditra + thinset under ditra + thinset over ditra.
Option #2 = Hardibacker with tile : 1/4" nominal tile thickness + 1/4" Hardibacker + thinset under Hardibacker + Thinset over Hardibacker.
I have the ability to adjust the subfloor a bit under the threshold. I currently have 1/2" plywood (original construction + 3/4" plywood, recently added by me. Next layer is either Ditra or hardibacker,
