the small bit of tile is the Illumini Lake mosaic.

I am not a big fan of a mini mosaic. I don't know your budget but there are gorgeous handmade tiles out there. Also, more budget friendly are ceramics with a handmade look. As an example... Grazia Melange Butter/Green tea blend:

Another view of the kitchen. Flooring going in.

So, do you like the small tiles? If so, then the Ilumini lake is a great match. The photos you included look more serene than busy. If serene is the look you are going for, I would opt for a larger tile, soft color, fewer colors, less busy, etc. Beautiful kitchen.

Beautiful kitchen!
I like the rixi tiles.
Heath also has some gorgeous greens.
If price is no object- motawi tile would be awesome! (very expensive!)

I'm the wife in this story. We thought we had to go with small tile because of the curve but we're not wedded to mini mosaics. I think we can go as large as 2x2 but not sure about larger tiles.

Not usually of mosaics but in that small a space it could work. But I also love green glass or ceramic like Grazia or Health with some variation in your space too.

No help with tile,but I wanted to say how cool I think that curvy bar is!

How about using the small mosaic (5/8'' sq.) on the curvy part and the 5/8'' x 3'' on the straight walls?

Since i haven't seen the tile itself, I can't speak to whether it looks like "factory" quality. I will say that I think the colors look fantastic and I love the idea of the mini mosaic on the curved wall. It would, I think, really set it apart and make it a focus point. How about seeking something larger format and plainer...that coordinates well with the mini mosaic for the rest of the kitchen? I wouldn't do the brick in the same mosaic...too much of the same and wouldn't make the curvy wall so special.

Here is close-up of the Illumini Lake along with some small bits of cherry and the Atlantic Green granite.

I think I could live with the small tile on the curve and something else on the other wall surfaces. I wonder what would work on those other surfaces.

We also thought we might enjoy a pattern such as the pinwheel or Craftsman pattern shown in this image from Fireclay. With a single color, there would be a field effect yet the pattern would provide some variety and interest.

We both are afraid of the busy look of the multi-color small mosaic. I can live with small mosaic when the tiles are close in color. When varied like the Illumini Lake above, they tend to make me cross-eyed--like some kind of optical illusion.

I can see using the mosaic on the curved portion and then only as an accent tile for the rest of the kitchen.

I changed my mind - that would look awesome on the curved surface!

Have you looked at Sonoma Tile? They have a big selection of colors and sizes so you could vary the sizes and have something that works with the curved wall too. If you find the small sample busy, then putting more of it on the wall probably isn't the best idea even if the colors work. There are plenty of options out there to find what you like as well as size options that will work with your space.

a2gemini, when you say that you have changed your mind, do you mean you think the Illumini Lake will be awesome, or are you referring to the two samples from Fireclay?
