We recently completed our pool and spa. The pool builder used tile in spa spillover which I thought looked good until he added this white plastic for tile edge. Can anyone recommend a different product to use on edge? Also, no matter how high the water flow is over the edge of the spill over the water is still running down the brick, which will cause build up overtime. I am trying to get the builder to extend the spillover 1-2 inches. How would this look with the current tile that is on the spill over? Should we replace with a different material?
