He's totally right - that looks pretty damn awesome.

IMO your tiler is a wizard.

What are you not happy with? I would be thrilled with that job and attention to detail and hope the rest of my project looks like that.

I just thought the edges of the miter should be closer together with a smaller grout line

Youre way too picky.

You should be thrilled with that tile work.

Excellent job.

I wouldn't want to work for you if you're that picky.

If the tiles were mitered, you would need to leave a grout joint, but with profile pieces like you have I would want the miter to be closed and tight, with no grout. It also looks like the cut in the top photo is rough. If that's the only issue, though, I would let it go.

We’re going theough similar things right now, but we have more issues with our shower curb. I’d say your niche miters look pretty good. I would much rather see grout than a void which could happen if they were too close together. at least with the grout you know its sealed.

Looks good to moi....
