Hello! Reached my next DIY task, Tiling! Currently tiling around my kitchen above the worktop and so far it's been a breeze. HOWEVER, I haven't installed the wall cabinets yet as I was waiting to see how big my tiles would be to see how high I would put them. My tiles have reached up 41cm but my boiler sits at 43 cm and will be covered with a unit, meaning I have approx 2 cm bare wall. Do I: A) cover this gap with a strip of pelmet all the way round B) Tile up to the units once installed (meaning super straight cutting needed) C) Tile an extra half tile up THEN install units so the bottoms is sitting above the tiles. (Which will make a neat straight line) My units will be hung, not screwed into the wall. Thanks!
