Look for a different backsplash. Choose countertop first. I don't care for those choices with your floor.

Maybe do the first grey one in the first picture because it has a lot of texture and it would look nicer then the marble because you have s different marble for your counters
Hope this helps!

Oh and marble countertops will look gorgeous!

love it! The marble will really pop with those floors!

I happen to like the choices. either one will work. I would wait on your splash until everything else is installed. I think you could choose a better looking tile.

Is that second slab Super White? it's a dolomite. I have it in my bathroom.

if you're looking for some other gray choices, I saw these at my local stone yard.

Eternal Serena quartz

quartz that looks like concrete.

I have the same color palette as your first example and really like it.

Blondie, nice choices! Similar to the choices I made for my kitchen. I went with a quartz that was more like your 2nd choice because I have an L shaped kitchen and I was afraid the strong veins from the first would bother me with a seam in the corner. If that isn’t an issue for you I think it’ll be beautiful!

Kim H brings up a very good point. You‘ll find numerous posts from people who are unhappy with seams and vein match-ups with the countertop similar to what you show in #1. That type works best in straight runs where there are no seams or turns.

Right?! I hadn’t thought of that either. I’ve seen them done really well and really bad.

Found this slab of granite. I love it as much as the calacatta, but will it stain easily being white? It will be sealed.

I like your first combination -- just talk to the counter guys about how they can fit a slab to your layout and what the seam considerations would be. There are solutions, some with creativity, some with $$.

@kim H - would love to know what your countertops are!

Lgiltmier they are Venoso from Pental Quartz.

Update! ( original poster, logged into different account I forgot I had )

I went with quartzite ( natural stone), and silvery subway tile. Love my new space, couldn't be happier! More pics posted in a different thread I posted “ before/afters”

That quartzite is beautiful! Which one is it?
