olldbobbi If you want to keep the monochromatic look you have going (beautiful!) see if you like the gray glass subway tiles: [houzz=Ocean Gray 4" x 12" Large Glass Subway Tile]
[houzz=Smoke Gray Glass Subway Tile 3" x 6"]
[houzz=Contemporary Kitchen]

househaunted How about something like this to make the white pop:

Frank Trimble Both great ideas. Since I'm a Realtor, I can't help but think of resale so don't want to get to carried away with color. I do really like the blue but it may be too much color. Also, we are installing a stainless back splash and self behind the gas range. Loving the glass subway tiles too. This site is awesome. We've been putting this off for 2 years. LOL!

sam0705 What about a classic marble subway tile? I think that would look beautiful in your kitchen. I almost didn't suggest it or was going to suggest it along with putting stainless behind your stove, but now that you're saying you're already doing that, that would be my vote.

apple_pie_order Beautiful kitchen. White or off-white subway tiles. The marble suggested by sam0705 would be stunning.

If you want more bright blue accents, add some blue towels that you replace every year when they fade. Or buy a wood tray and line it with bright blue tiles.

anyalabunski How about combination tile class and marble. They come in variety of colours and combinations. Also I wouldn't t go w subway tile I don't find it attractive enough but stainless steel would look great in round or square tiles. See pictures. I also like bling so if u can Sind a pearlescent tile in a large scale it it reelect lite and will give u subtle colour as well. Have fun

Frank Trimble Loving the Marble Tile idea too. Do they make a porcelain marble looking tile?

anyalabunski Hello Frank. Yes there is are porcelain tiles that look like marble. Look at the houzz link below

LizaJane I like the subway tile in white. Classic, simple and will not go out of style.

kkenning what about this from the tile shop? It's carrara marble and really pretty. I have it in my kitchen.

Frank Trimble I like how this would bring the white and grey together. But might want larger tiles.

calidesign Your kitchen is clean and timeless. I would go with the large glass subway tile, a plain white subway tile, or the marble subway tile. None of those choices will look dated and will help you maintain your resale value down the road. Your blue accents in the window are beautiful, but they are changeable, and I think you could regret a bold choice on a back splash.

sam0705 A favorite marble backsplash from houzz

REDinterior I like the idea of using a calacatta or carrera to tie the white cabinets to the gray/black soapstone. Calacatta is white with grey veins and carrera is typically a pale gray with grey veins. Both can have a hint of rust in them. The herringbone pattern sam0705 has above would add some great texture!

Frank Trimble Y'all have been awesome! Narrowed it down to glass subways with stainless and the carrera. HUGE thank you!

olldbobbi Congrats on making your decision, probably the hardest part! A word of caution, be careful when applying the mastic for the glass tiles, you don't want to see notched trowel lines behind the tile. Saw this mistake made on a Sarah Richardson design show, they had to tear down the entire shower because of the trowel marks.

tallest Everyone recommends glass subway tiles. Is this some hot trend?

Why don't you use a whole white piece of glass as backsplash? Super easy to keep clean.

Stoneshop My vote would be for the marble subway tiles. It would look beautiful with the classic design of your kitchen. Your soapstone is stunning!

sam0705 I'd love to see the end result!
