I'm adding a tanning ledge (10'x12') to my vinyl pool. I'm going to pour it using concrete and want to cover it with Diamond Brite to give it that beach entry look. Has anyone ever seen this done. I'm going to recess a 1 1/2" x 2" piece of plastic in the front side of the concrete tanning ledge to attach the step trim to it after putting in my new liner. Water depth will on be 10" deep in this area and I don't see any difference between this and fiberglass steps in a pool. I know most people don't like hybrid pools but doing this out of vinyl would keep me from doing the beach access.
