Do you have any ideas of what we can use to update this spillway other than using the same tile as the waterline tile? We looked into granite but that seems like a huge slip hazard and we looked into slate wall cap but wasn't sold on that idea. We are resurfacing the pool and replacing the waterline tile to a light blue 6x6. Any ideas are greatly appreciated. Spillway picture is below.
