We are tiling the walls in the bathroom up to 41" with white subway tile continuing into the shower up to the shower head. There will be a black trim edging around it all. The bathroom floor is 12 x 12 white towels with Deloreon grey grout. The vanity is white the countertop is black granite. I origainally bought white grout for the subway tiles, but my husband made a comment that it wouldn't show the brick pattern he is using with the subway tiles. I'm wondering if this is going to be too busy. The walls are painted grey tint. Please I could really use your opinions on this.

Thank you
