A few weeks ago I introduced myself to this forum with should-i-remove-the-grass-t45953.html topic.
I figured now its time to post a few pics since the pool has been up and running for a week. True, it's a small pool, but for starters with two little kids I figured it will last us for a few years before we ready to upgrade. I originally started with putting it down on the grass (on top of tarp "sandwich" with foam insulation in-between). The pictures below were taken while I'm pumping the water out (once it got below drain plug level, I used sump pump with attached telescopic extension to project the water out)
Back when I first started filling up the water, I realized the level was off by a few inches. Probably not the end of the world considering it's a small pool and we are not making too many waves, but when I start thinking about it being a seasonal thing with dead grass/mud when its removed, I decided to turn it into a more functional space we can enjoy once pool is stored after a few months of use. We hired landscaping/hardscaping company to install pavers (Cambridge brand) and make a privacy wall with some trees around it which creates a nice isolation from neighbors. Our backyard is more like a side yard, and the patio space was limited to 16'x16' (perhaps in a few years we can upgrade to 14'x42" Intex). From the pics above you can see we had a few pavers already from the original owners of the house (we moved in 2 years ago), but those were not done properly and had to be removed. Here is how the new space looks before the pool.
And here is with pool going up and the same tarp sandwich underneath
Sorry for picture quality, took it with my phone. So far, it has been in upper 90s up our way and we had 3 days of enjoyable pool time. 12' is not much, but fits perfectly two adults and two kids (4yr old and 7 yr old).
