Another photo

Definitely a VERY sloppy job. In the first photo you can see where he even failed to remove all of the blue painters tape.

I'm strictly an amateur, but even I can manage a better finish that that mess.

That's a mess.

Tile edging or bullnose tiles would be a better way to end the tiles neatly.

Metal tile edging.

What are we looking at? Is it even right side up? The caulking should be paintable. If not, it's an amateur mistake.

This is what I thought, I expected it to be completed the same as caulking trim, with max 1/8 inch of caulk on the wall, there is around 1 inch plus which looks terrible, I shouldn't of had to specify this to the guy?? I thought it was a given?

That is clueless caulking. Demand a do-over and don't pay until you get it.

Bad caulk job, but fixable. More to the point, who was responsible for the design & layout, i.e. who made the materials list and did the purchasing?

We wanted the caulk around the edges and bought the sanded grout caulk stuff. I was just under the impression that the caulk would be thin and neat, the same as caulking trim, not like an inch onto the wall

That joint seems to require an unsanded caulk joint, followed by paint. Somebody needs to scrape/rub all that off and start again. That might include removing the caulk from the tile edges with a blade. (Hint: the same guys have already demonstrated they are not the ones to redo it.) Mask it, apply caulk, tool it, remove masking tape, tool it once again, allow to dry. Then paint.

The real problem here is that you didn't use bullnose tile on the outside edge.

the tile installer did that with the caulk because he's got to transition from the wall to a 1/8" tile. Of course it looks bad... but you need to start with the correct tile.

Agreed that this installer isn't the right one. I suspect that you bought the materials though. He should have told you no until you had the right tiles to do the job.

Schluter profile is the thing to use, if there is no / you didn't want bullnose.

Google Schluter.
