The floor/shower floor is Daltile, Continental Slate in Asian Black. Shower wall is Daltile Modern Dimensions in Arctic White with Daltile Coastal Keystones CK88 Tropical Thunder listello.

Are you sure it's not English gray? It looks so much lighter than the Asian black I've seen in person. But this is the look we want. Could it be lighting making it look lighter?

This is a comparison. Doesn't it look like the lighter one? The left is English gray, the right is Asian black. I want to do this in our bathroom, we have very similar cabinet and counter. Don't want to select the wrong tile. :) appreciate your confirmation.

The tile color is Asian Black. The lighting in the photo is making it lighter - it's much darker in person.

We've used Light Pewter grout.
