Simple Bath Floor Questions
The old house I am renovating has 1" T&G fir plank flooring directly over 2" x 10" rough sawn joists spaced 18" OC. In the new small bathroom that has just been roughed in, I was considering laying down 5/8" sheathing over the plank flooring and then installing ceramic floor tile over that.
My first question is, should I count on installing a layer of cement board (1/4" perhaps) on top of the sheathing before the tile goes down? My second question, which is related to the first I suppose, is what additional "thickness" should I plan for due to the "finish floor" (i.e., the added thickness above the sheathing)? Can I keep it to 1/2" total with ceramic floor tile?
