Hi
I have floor joists first (with extra noggins) then 18mm WBP plywood going down which will be screwed down, then 6mm Hardie Backer Board before the tiles go on. With the current set up it would be approx 17mm above the currnet level. There is approx 15mm dip from the hallway into the bathroom so it would ballance itself out...
Question is now "The Boss" is thinking about underfloor heating as well. How much more would it add to the levels? Do you need a special board to reflect the heat upwards, or is it just a mat?
Thanks for you help and advise as always
