So I will be laying some tile over the holidays in the kitchen, entry and bathrooms. From what I've been reading you are supposed to only put it over plywood so the grout doesn't crack. But here's my dilemma. I know the subfloor is OSB but it seems that in the kitchen, entry and bathrooms that there is another piece of wood over the OSB that is approx 1/4-1/2" thick to bring it up to the level of the living room given that the lino needs the extra height to bring it up to the carpet (now hardwood). With the current height if I put down tile it will make it the same height as the hardwood which is what I want. If I have to go and screw down a sheet of plywood everywhere then my tile will be much higher, which is what I don't want. Is it okay to lay the tile on top of the board that's already there on top of the OSB? Any other tips for laying tile would be appreciated. Thanks!
