OK Here I go.
I came across some ceramic tile (12x12) at a reduced price
(.77 ea). The PEI rating is a 4(lV). Which I was told it stands up to more traffic than less rated tiles. I have never done tile before, and willing to give it a shot.
1st project. Upstairs bathroom 6x5 in size. My flooring is 1/2 ply with 2x10's 16" center. Will this work with 1/4 backerboard?
2nd project. This is where I am afraid to attack. Entry way from garage and kitchen. Approx 8x12 in size. Not sure on the ply under the vinyl, but I have 2x10's on 16" centers. I heard of the min requirment and L360 and really not sure what the hell it really means.
Just looking for some advise.
P.S. new to remodeling scene, but I was apprehensive about gutting a bedroom few months back, to put new moldings and lam flooring, took my time and looks as well as a pro. I take my time to make sure it was right. Just want to do the ceramic right. Please put your 2 cents in and help me.

Hi Mike

The upstairs bathroom is a no go. 1/2" subfloor is not adequate for ceramic tile. You need to add at least another 1/2" and more would be better. 1/4" backerboard on top of that would be fine. Are you sure its 1/2"? Thats unusual. Also what is the unsupported span of the floor joists?

My guess would be that the subfloor is probably the same throughout the whole house so the entryway is probably not good either. The vinyl and any 1/4" underlayment MUST be removed. What is the unsupported span of the floor joists? Deflection is the degree that the floor will flex under a load. You need to meet L360 for ceramic tile.
