On the new houses we usualy add 1/2 plywood on top of the 5/8 OSB we use for the floors. We use those engineered truss beams for the floors to commercial spec so the floor is already pretty stiff.

Doing this the tile levels up to the hardwood floors, so you can just finish it against the oak floor.

Also we use 12x12 tiles because they are the easy to install and cheap. At least our tile guys like 12x12.
