What type of accent tile would you suggest w/ Shaw Alpine (Gray 105) for a master bathroom. Considering Sahara Carrara linear marble.

Go to floor and decor they will gladly help you and look at multiple pieces of the same sample next to each other not just one on one because they reflect and take color from each other and if you look at one little piece you might not they have like it after it's all together they have some good consultants there too

Your best bet is to ask at the store.

I would do something with glass accent, simple and clean, a single ban horizontal a 1/3 of the way up from the floor. Or you could do a traditional center ban
