That’s probably because your tiler is just a good general labourer who happens to know how to tile. Please note I’m not saying he won’t do a great job.
Normally a tiler would request these things before the job starts or at least ask if you want to use these things.
like even I know how to tile (I would only do this myself in my own home though... I lie, even then I use my tiler haha). I do however miss tiny things that matter to a tiler. I remember when I was out at
@WAslayer to play with him... wait wait I mean quote. I took measurements and the bulk of things I noted, yet I insisted I go back with my tiler for him to be sure I didn’t miss anything... which I did. This is exactly why I always insist he checks out a site before I quote.
When I say tiler I mean a guy who won’t do anything else except tile because tiling is all he knows and he knows it very well. He won’t even have anyone mix for him and I was forced to take his guy along with him. No regrets though, the two of them work together so well. The assistant will have things ready without the need for him to ask at all.
