Pictures would really help....

photo's yes. The profile edge options available would be discussed with the client in the design stage. ( bullnose, pencil, after market profiles, fabricated trim etc.) I could not price a job with out this decision.

They also make colored painted and colored plastic edgings.....

The full guest bath in my 1939 house renovation, chrome edging was used on the wall where the robe hook is located. It made sense for the wall and age of the house. Vintage look.

However, in my new addition master bath, I specified marble pencil trim to match the Carrara subway. My contractor wanted to use white plastic and I vetoed that idea and spent the extra money for the pencil trim. Still under construction -- glass is being made.

We have used Shluter trim several times. The customers liked it...I am still not convinced. I like the look around shampoo niches...it gives them a modern feel.

I neither like the Schluter edgings/trim nor bullnose or pencil tiles. We used through-color porcelain tile which in my opinion looks great by itself, as the cut side matches the color of the front of the tile so we didn't use any edging/trim or bullnose. We did hone down the sharpish visible edge just the slightest bit though.

If your spidey sense is acting up and you aren't comfortable with what you're seeing, stop him now! I suggest a heart to heart with your contractor. What can be done at this point depends upon what happened, i.e. whether this was something you talked about and agreed to during the design stage, or whether he just started doing it on his own, which would seem a bit odd. But even if you originally agreed to it, if you don't like the way it's turning out, don't let him continue. You might have to pay for him to re-do the part he's already done, but better to do that now and end up with what will make you happy rather than to not speak up, feel totally uncomfortable with the whole thing, and end up hating your beautiful new bathroom! I usually know to follow my gut on stuff like this because our guts are usually more accurate than our heads. :-) You're the boss here. it's YOUR bathroom and you should make sure it's what will make YOU happy! No need to be confrontational or to blame him for it not turning out how you'd hoped. Just a "Hey, we really need to talk about this trim; it's not doing for me what I'd hoped Can we sit down and talk about some options?" Your contractor, if he's a good one, will want you to be happy as much as you want you to be happy. Hope this helps! :-)

I did exactly that!! We have decided to continue on with a white plastic trim which marries the tile together for a more seamless transition,which is what I wanted. Thanks for all of your comments as they validated my concerns.

I've never seen chrome-edged trim on tile, but in my imagination, it's not good.

They make nice, flat satin nickel trims that I think would look good with marble, be more modern than bullnose for tile edges.

If there's a Porcelanosa showroom nearby, go check it out. They are using a lot of chrome profile trim in their showroom designs and it looks great.
