In the past I've used a radiused subway to turn the corner. It softens the corner due to there being more tile and fewer grout lines. For the base I'll use the inside or outside cove corner pieces to turn corners. Here's an example of a radiused subway for turning a corner: In your case it sounds like you want the outside corner quarter rounds to be black so they will almost frame the wall tiles, In that case, sure, you can simple have a vertical run of black outside corner quarter rounds to turn the corner for you. Your questions: 1. Yes, you can do that. 2. I'd use true cove corner pieces on the cove to turn cove corners. Running quarter rounds to the floor and having the coves butt to each side of the quarter round? I don't see the profiles matching up at all. 3. See answer #2 above. If you run outside corner quarter rounds to the floor, the profile of the outside corner quarter round will not match the profile of the cove. So use cove corners for turning corners with the cove.

Here's a pic of an outside corner in our guest bath: (I don't have a close-up photo of the corner handy, but if you can zoom in on this photo, you can get a good idea how it looks.) I'm sure one of the tile pros can tell you different and best ways to do this; I can just tell you what we did. Our contractor miter cut the tiles, then slightly softened the sharp edge with a sanding block of some sort. We had talked about using a bullnose tile, but I didn't love the edge finish of the bullnose on these tiles; the cut tiles came out well and I'm much happier with it this way than the way the bullnose would have looked. -- Eric

Gosh thank you folks! Boxer: the first five basically have what I'm looking for. I want to see examples of where the cabinets wrap around a corner just like what numbersjunkie and oldiegirl have shown. I just can't decide if we should go with a 90 degree angle or if we should use some angled cabinetry. I'm thinking it will have to be the right angle in order to fit in all that we want. The issue I'm having is my two runs are both very short (56" and 20") and the long one has to fit a refrigerator. So I would like to have an 18" cabinet, 36" fridge on the long side, then have cabinets facing the other direction but backing up to the fridge and the short section. Crazy???

there is one schluter product with a 5/8 inch profile. I would prefer to miter but have heard it is tough with cement. Haven't tried it yet though.
