I need to tile over a concrete floor on ground level (Utility & WC) and a first-floor timber floorboard floor (bathroom). I've bought some 144mm x 895mm wood effect tiles for all three rooms. I also have some Schluter DITRA 25 Uncoupling Membrane which I'm planning to fit directly on the concrete floor.
Do I need to put cement boards on the bathroom floorboards before the uncoupling membrane or can I put the membrane down without the cement boards?
Also, with the size of the tiles do I need tile levellers? I saw a guy fitting the a similar tile on youtube and he didn't use them. All the other times I've seen them used is with larger tiles.
