My bathroom floor has 20x20 brick pattern laid out. Is it going to be too busy to lay out my shower surround with 4x8 subway pattern. The 4x8's are the same Color variation of my 20x20 floor tiles. Help. Need to make a decision. I planned this a while back to do the subway and when my tile guy asked me how I wanted the bathroom floor lay out I told him brick & totally forgot about the 4x8 subway plan. Should I continue with that plan or go with 6.5x6.5 square and install straight. ?
