In practice a slight step next to a carpet is not noticeable really, get a angled door strip that grips down to the carpet. A decent underlay + carpet will be verging on 15mm+ anyway, so tiles at say 6mm of hardibacker, 2mm adheisve, 10mm tile isnt really far off.Obviously not your fault, but this whole thing is winding me up. Our new build house has posh laminate in the upstairs bathrooms. I want tiles. I don't like laminate. But it's so thin that if we did put in tiles, it would be raised a couple of cm, as you say, from the carpet on the landing. Is this normal? I don't understand why they wouldn't have made provision for this. Or is it a case of putting something under your carpet to raise it up??
