Do you like it? Are you happy with it ?
Personally I think it looks terrible and he's made a mistake in the set out which has led him up stupid street.
That’s my issue with it, in order to match that trim should of been placed on the top of the tile so the trim joins with the vertical one as it does around the window and on the other side of the bathroom.
It’s not something I’d do either. It’s an odd decision to make in my option. Perhaps ask the Tiler why he did it. Sometimes people get set in their ways and need to be told when something isn’t right which in this case it certainly isn’t.
