I am going to tile our kitchen floor, after I have ripped up the 18mm chipboards and laid down DWP. But as the existing floor is only about 4/6mm below the hallway floor, and if I use 18mm DWP then say about a 8/10mm tile on top, that would make it approx. 24mm above the hallway floor. If I use 25mm DWP plus the tiles and grout, the floor would be about 30mm above.
Is there anything I can use to compensate? for that amount of step?
