Do you need to waterproof under tiles?
The bottom line is that you shouldn’t expect tile flooring alone to prevent the intrusion of moisture.

Is 3/4 subfloor enough for tile?
Tile installed over wood floor systems MUST have a minimum of 1-1/4 inches of solid material beneath it. This means you can have a 3/4 inch wood subfloor covered by 1/2 inch plywood, cement board, or approved gypsum fiber underlayment.
