What color are you painting cabinets? I wouldn't choose backsplash until the painting is done.

Says they are painting cabinets white.

Since you are painting the cabinets white, I would go with one of the backsplashes with some color in them. White subway tile and white cabinets--too much white IMO! Tile size is a matter of taste.

Stop, you have a curb. Are you removing the curb? If not, you don't need tile on top of the granite that is already going up the wall. If you intend to remove the curb and take down the granite that goes up the wall behind the stove then it would be OK to tile, otherwise just paint and STOP. If you remove the curb and the granite behind the stove, then look at Biltmore from the Tile Shop.

ditto what bell said. that current curb you have takes up 1/3 your wall, and over half near your dishwasher. trying to add a backsplash on top of that will not look right. if you want a tile splash, remove the current piece.

before you decide on anything, have the cabinets painted first.

Sorry, I should have mentioned that the curb (didn't know that's what it was called until now!) is being removed, as well as the portion that goes up to the range hood. The cream-ish glass and stone tile has already been purchased (a great deal at Costco), but am worried that the tones will not match the white cabinets or dark countertop.

if you can return them, I would. those aren't the best choice for your space. wait until the cabs are painted before picking something! you can't install them anyway till after its done. you don't have a large area to do, so it's ok if you find something out of Costco's realm.

the linear bars are too busy. try a solid glass or ceramic.

grays or greens would work

or if you like the linear bars, do all one color.

This is honed basalt. (this would look great w/your countertop and white cabinets. get some under cabinet lighting. this stone is beautiful. I have it in my shower)

and a taupe colored glass.

Hi Beth, thanks for the great advice. The honed basalt is really nice, but our kitchen is so dark that I'd probably go with something lighter, like the gray or green glass tile you show. Thanks again!

remember, you are doing white cabs. it will brighten up your space tremendously. the honed basalt is actually a dark gray charcoal color. w/under cabinet lighting next to your white cabinets, will look stunning. really.

Thanks again. I'll make sure to get a sample after the cabinets are done. Know of a good store/vendor to purchase them from? I may come back with new pics to ask for more recommendations. You've been very helpful!
