I prefer the subway and would probably go with a larger size, so there is less pattern. You already have a lot going on with the granite. You could also do the subway in a gray tone from the granite.

With the amount of movement on the granite, consider a simple backsplash. Otherwise the look will be too busy. I am afraid I have a variation of the octagon pattern on three bathroom floors - and I've seen it on many other bathroom floors:) So I like it, but it makes me think "bathroom floor". If you don't like subway style, a different shape with a non-contrasting grout in a similar color would work.

Try arabesque shape

No to both of those, especially the left one.

you need a larger tile. don't get anything on the sheets.

Except maybe this one. I like it w/the off-white grout. this would be nice w/your granite and cabinets

It's from Tilebar and below I added a few more options. order some samples from them

Shadebrick in the off-white color (google this name. many diff tile places can get it for you.)

all the others I listed can be found at:

Tilebar.com (go over there and get 5 samples for $5)

or Manchester Vanilla 3x12

this is diff and might look cool

or maybe a 4x4 crackle glass in this pattern

Tilebar also has this frosted glass in a Sand color 2x8, Loft series

if going w/a subway, go w/this size (the one on the right)

And something like this rich chocolate tile w/thin brass inserts would look stunning

this one is a large format, but perhaps you can find something similar . or, a really good tile setter would be able to cut these tiles in a size for your backsplash (say, 4x12) and then use the gold schluter metal strips as your brass inlay. It would be a bit of work, but no one else on the planet would have this exact backsplash w/your Alaska granite! a lot better than everyone in the world using white subway tile w/this countertop!

They do have this 3x6 metallic tile. Nabi Copper

Deanne - Love the kitchen!

love Beth's suggestions, we have the copper metallic ones, with a black pearl granite

Beth H. - That brown with copper looks killer.

Kelly, I agree. I think a rich coppery brown tile w/a brass inlay would look gorgeous! and so unique. A good tile guy would be able to do these grout lines with a brass Schluter Jolly or something similar. I've heard of gold grout, but not sure how it looks.

Some tiles come w/the inlay already on the tile

So tired of the standard 'white subway tile'.

Also have a metallic tile in the bar which I like, the copper color you showed would look great with your granite! Happy decorating

With that busy counter I would use subway tile.

I have a similar granite. I did glass subway tiles but put them vertically instead of horizontal
