Do you have that same tile on the bathroom floor?

Is it too late to change the vanity?

I used a porcelain marble-look tile in my master bathroom, but I paired it with a stained wood vanity and a white countertop (Cambria White Cliff).

Just about any white marble slab that would be close to the white Calcutta. We did that with two different white marble-- in the shower and for the countertop-- and it all just blends. We were fortunate to find a remnant slab they cut a hole for the sink.
