tile over plywood?
You can not tile directly over a single layer of plywood (subfloor), you would need to add an underlayment of at least 3/8" ply or thicker. That is IF the framing was built sturdy enough. Can you tells us how this platform is constructed and with what?
If the framing meets standards you're better off installing a tile backer board or a membrane such as Ditra if you're able to buy just a small amount.
