I like B it goes better with the floor and island colors.

I like A's profile and B's color. The 2x4 bevel is very nice but is too similar to your wall color selection. If you could find that profile in B's color I believe that would look spectacular.

These tiny samples will not be the best way to make your choices.

First, get the cabinets and counters installed and then look for wall color and backsplash.

Stand back 10 feet to view your splash tile color with the counters and put it on a board so you can stand it up just like it would be installed on the wall. Laying it flat picks up the light differently. Don't look for tiny specks or undertones that won't be able to be seen from a distance.

Good advice above. The point it is you have chosen the starring element. A back splash should be much quieter than a starring top. I'd select a simple subway, grout in the palest tone of the gray if you need more interest. DON'T mix a real marble anything with quartz. I'd skip the bevel in favor of a 3 x 9, or 2 x8 .... and use a 33% offset install. All selected after install of everything else. It's the very last thing to get installed in any scenario.

Dueling tops and splashes are all over these pages, from mostly ? design over think: ) Simple and beautifully edited is never boring. Or out of date.

Word of advice! If your kitchen layout has a corner turn on a perimeter.......BEWARE of this solid surface and very aware that there will be the possibility of mismatch in vein seaming. That's a virtual guarantee. Be sure to have much discussion on this, with the fabricator and installer, kitchen layout in hand when you do.

Thank you everyone for all of the great advice! My preference is as some of you said the darker gray color of the glass title, but the profile of the beveled subway. My builder requires I make all these choices up front so unfortunately I will likely not be able to have the countertops installed before choosing my selections. Unfortunately these are the limitations I am working in. The one thing I considered was telling them no backsplash then having my own installed.

Jan - Such great advice! I agree to keep the quartz the showpiece and let the backsplash fade to the back. And such a good point about seams - We didn't consider it when designing the size of the kitchen, but quickly adjusted the size of the island to work within the size of a jumbo slab and avoid any seam issues.

I would do a simple white subway tile, but not the little size that you're showing there, use a standard size.

I would go with your option B the glass back splash picking up the gray tone in your quartz counter top. I have combined those two materials for a Client's kitchen and it looked amazing.

Hi Tricia (and others)-

I just had the same Silestone Calacutta Gold countertop installed, and my backsplash is only partly done now.

It is a medium-dark grey glass subway tile (3'x6'). I'm wondering what you ended up doing, as I have not yet decided whether to use a glass subway mini-tile pattern of grey and white tiles, or if I should stay with just the grey glass tiles (similar to your Backsplash B). Would you be able to post a picture of your finished countertop and backsplash? I have to admit that my white cabinets along with the whiteness of the Calacutta Gold is too much white for me.
