Your first post on this topic said Bayram charged you 150TL. He came twice and the call out charge for each visit was 30 TL. Your second post said Bayram bought 15 tiles, one bag of grout and the adhesive and he took the shower off the wall and replaced it, when the tiler had finished his work. Oh, and the tiler got 60 Tl for his work.
I think this is an accurate account of what you said.
So to sum up, the tiler got 4 Tl for each tile he replaced, all materials provided. =60TL.
Total cost you quote is 150TL, leaving 90 Tl for Bayram, who visited twice ( for his removal and replacement of the shower unit and the bits and bobs of the plumbing kit used for this and also the purchase of the tiles, grout and adhesive. If you subtract your stated call out charges of 30 Tl per visit then it would seem to leave only 30 TL for Bayram to cover his labour charges and the cost of the tiles, grout and adhesive.
Bayram must have been upset to charge so little. In fact, out of his mind!
It looks like you got a good deal. Please correct me if I have misquoted you.
