Bullnose trim pieces are available in a lot of tile lines and can compliment the overall design. What is the look of the tiles selected? that can help to decide what works best for the finishing pieces.

We will be using this Forum Ivory tile on shower walls and wall around the tub with probably a river stone floor and some accent in a nook and along tub wall. I like the sleeker lines that the aluminum edges provide. There is bullnose available for this but seems more expensive to go that way and you have to caulk the edges.

If the bullnoses are available, then use them. It makes for a more cohesive look without adding another element. You may save a bit going with the metal trim, but that will go out the window when you'll need the metal edge corners; and if those are not available how well will the installer make those mitre corners?

Installer should be able to make the mitre corners. I noticed you used it in your Bed/Bath suite project and I really like it :)

Kudos on the installer on that project, he's been doing tile for a very long time! But you will notice that the only spot he used the metal edging was on the outside edge. He mitred tiles for both the outside corner wall and the niche cutout.

I always make sure to pick out tile that has matching trim pieces available. I will never use the metal trim, to me, it never looks right.

Bullnose gets my vote!

I like the metal trim for contemporary/ modern installs. Bullnose for more traditional baths.

I agree bullnose to me is always a traditional look and I never use it at all I think it looks bulky at the end of a row of tiles I much prefer schluter but of course it needs to be installed while the tile is being installed it does not work for an add on.

And this is why there are choices, and why I said the only choice that counts is YOURS. What do YOU think looks good?

I did find the Schulter trim in a cream/tan color pvc that is apparently very durable. I'll probably go with that as it looks like a pencil edging.
