Jeff....the shelf/beach area is basically a 10 foot radius, so the shelf is 10 feet and the beach at the widest and deepest part is also 10 feet. The shelf accommodates 2 chairs easily with room for 2 more. Below are pictures of the shelf with two chairs in place.
At the time we built there was a mini pebble and standard pebble size available for the River Rok. I remember bringing both home from the PB to help with our decision on which to choose.
Both were smooth to the touch and should not rip bathing suits. We chose the mini pebble to help achieve the sandy beach look we were after...the standard pebbles would have looked more like a pebble beach.
The diamond brite has been fine...no regrets with this decision. It is smoother than the river rok which is probably a good thing for the sports end of our pool with volleyball and basketball activities.
All the rocks are from a company called RicoRock. We were selective on the look we wanted and the RicoRock products appealed to us most. They're engineered rocks that are designed to withstand pool environments while at the same time looking like real rocks. They're made from molds of rocks found in South Dakota and we toured their factory in Orlando to touch and feel the product first-hand before making our decision. All their boulders and waterfall kits can be purchased with or without notches. Most of ours were ordered with notches for around the pool except for a few that were submerged on flat surfaces in the pool. Below is a link to their website for more details.
Lastly, our PB recommended using low voltage lighting which influenced our decision mostly. The alternative was fiber optic, but that just seemed too dim for what we wanted to do with our lighting effects. Plus, the low voltage lighting was readily available locally with many different options to fit our specific needs. No code issues with 12V.
Hope this helps.
