I know , I know . Simply by knowing the tile sizes , recess size and adjusting stud to suit you can mitigate lots of Trickiness !
The problem on a first time self build you don’t know what you should of planned until you get to that point . Some things I have planned and I think how clever I am when it all comes together . Other times ????
So in a way I am a better tiler than @Nickfromwales as I have to deal with more difficult situations, he just takes the easy route by planning ?
