My house had 3/4" oak hardwood on top of the subfloor. I am the one installing 3/4" plywood in place of the hardwood floor as it was heavily damaged over the years and has several repairs.
On top of the plywood, I will be installing Schulter Ditra Uncoupling Underlayment. This helps to keep tile from cracking, due to any floor movement. I won't have much movement as I screwed down the floor tight vs. original nails.
