I am now on a countdown clock. I have to pick a water line tile. My spa is a rectangular raised spa with two notches for a water fall. My coping and decking will be a beige stamped concrete. My plaster will be French Gray. Now I have to figure out the water line tile before my husband blows a fuse. I am thinking something electric blue. The tile company suggested we do something different to break up the large wall of the spa. If you have any suggestions I would really appreciate it.
