Tanning Ledge/Beach Bubbler/Fountain Suggestions

[JLove]

I had a "shallow reef" built and it's quite the hit not only with kids, but their parents too. Really helps build up the young ones water confidence. Both my boys were already swimmimg when I built the pool, so it as more for guests and aesthetics (also had a umbrella mounts installed in the reef)

JLove, how deep is your ledge? What would you recommend for depth?
