No unfortunately. I plan on removing the rocks and installing some kind of mesh/screen around the base this weekend.
The weather in New England has not been too great up till recently. I wanted to test the thing out before getting it all secured.
We finally had 4 adults and 3 kids standing/sitting on it over the weekend.

The steps were built last Saturday and really make the whole thing useable.

BTW, the deck extension was built last fall.
Also have a large sand filter/1.5 hp pump etc that was tested last summer on the 8 foot intex seen on the deck.
Heating system consists of 6 50 foot black rubber garden hoses with home built PVC "manifolds"

The Total project (incl deck extension with trex like boards/pool/pump/filter/shallow end/steps/solar heating) is still under $2000 so I am pretty pleased with what I have achieved

Some kind of fencing next
