Any of them would go with your cabinets and marble. What look are you going for? The 2 x 6 and 3 x 6 rectangles are classic and traditional. The larger rectangles are more modern looking, and the 6 x 6 is also traditional, but not used as much these days. I like it very much--it has a more English scullery kitchen look. The most dramatic is the interlocking one (not sure what its name is). It gives a very different almost Moroccan look, and is very nice as well.

Here's a photo of Walker Zanger Gramercy Park 2 x 6 crackle in "Pipe Smoke" color, with beaded and black liner tiles, in a kitchen similar to yours:

Closeup:

Your kitchen is beautiful. I even like the ogee edge - a lot. As diana says, all those tiles are great and would go. Some things to think about: The wavy edged tile is going to play up the ogee edge and make things more feminine and french - ish (in a good way). The 6x6 would take it in the other direction. The thin rectangles are playing it safe and would probably "go" the best, but you've got a long space there and they are going to make it look even longer (altho the camera angle could be making it look longer than it is).

I ended up sketching out a couple of sizes of subways on a sheet of paper, photocopying that and then taping them up to get a true idea of what they'd look like (but I'm a little obsessive).

I think Dove Gray Arabesque Tile 8mm would look really lovely in this kitchen. Travertine tile Silver Ash Tumbled Veneer or marble Tundra Gray would also look great.

I like these 6x6 ideas from above and a little different tones than what I've been looking at. @DianaBierInteriors,LLC not sure what look I'm going for?! I just need something to make it look less "dressing room & vanity feel" with the marble and white dove cabinets. I think once the stainless is introduced in sink and refrigerator it will break it up along with furniture moved back in our adjacent room. I have several pine pieces in there so I guess "Country French" although it's hard to pin down in this galley style layout -originally I was going for a "transitional" look but these cabinets don't lead me in that direction. Just to compare these are the two Walker Zanger 2x6 options. I'll try to find the pic of Wedgewood Blue used in another kitchen along with the one you shared with me in Pipe Smoke. Might be too busy on the long run I have though.

this is the Wedgwood blue Walker Zanger tile although I'm not crazy about it used with this particular Danby. You get the idea of the smaller tiles here.

have you looked at Encore ceramics? this is their 2x6 in silver crackle but there are plenty of other colors, shapes, sizes and you can blend colors.

in their Silver:

and their Eliot Cameo Crackle

and their Storm crackle is beautiful

Fireclay has foggy morning

I like the liner, maybe in a darker grey.

How about a tile that has color variations? This example is a Walker Zanger tile.

Have you thought of a soft warm green or a light blue? It would be a nice contrast to your counter tops and cabinets.

Hartntex, We are looking to use Adex Ocean Surf Gray as well. Would you be open to sharing final photos? Thank you!

@LL LL I actually ended up using this Walker Zanger tile in a 2x6 wedgewood blue which is actually more griege! http://www.walkerzanger.com/collections/products.php?view=mat&coll=Gramercy+Park%E2%84%A2

the second photo above actually looks like the WZ tile in the color "pipe smoke."

I would consider going white instead of gray.

Hi hartntex, would you share photos of your kitchen? I'd be interested to see how it turned out!

@dianabierinteriors - here you go!

tile before grout - Wedgwood blue color but looks grayish/greenish depending on lighting.
before window treatments

Wow, that is absolutely gorgeous! Enjoy your new kitchen!

opcion 1 or 3 ! the 1 for the shine and 3 for the oroginal form!!! good luck!! enjoy your kitchen!!

It's gorgeous! May I ask where you were able to receive samples from? From pictures online, I am going back and forth between the pipe smoke, brownstone, and Wedgwood blue. Thank you for your time!

@hgtvrules my decorator provided me with the initial sample of wb. I obtained PS sample directly from the WZ showroom. If you direct message me I can also send a photo of another friend’s kitchen where pipesmoke was used with a zodiac quartz material. I’ve never seen the brown used. I may be able to help if I know what material you will be using.
