I am planning on laying ceramic saltillo tile in my laundry room (aprox 11' x 8 ').
This room is in the center of my house, and you must pass through it to get to the master bedroom, so I'd like it to look nice (odd layout I know).
My concern/question - Before I bought the house (in December 03) the seller replaced a ruined press board floor (I think it is called press board.. it is like pressed saw dust, and expands if wet.) I had asked that it be replaced with 3/4" plywood, but didn't get my way. they put down more press board.
So, now I am ready to tile... and I am questioning this subfloor. First, it is nailed down, not screwed. I do not know if any caulking or liquid nails was used between the floor and joists. One small section does squeek, but otherwise it does not seem to be flexing or squeeking.
I want to do the job right, and am considering pulling up this subfloor and putting in 3/4" plywood, with screws and with caulking between the floor and the joists. I am getting conflicting opinions from a variety of people- some say that just laying down concrete (wonder) board with a layer of thin set between the press board and wonder boardwill provide the stiffness and water protection, others say to pull it up an put down plywood then the wonder board, some say lay a membrane down then the concrete board.
So, what do all you flooring experts think?
I'd like to do it right, and not have to re-do it anytime soon!

Thanks tons!!
