Steve from Mesa, AZ here.
The only pool I owned previously was a large kiddie pool with the inflatable ring. It's dark blue color and small volume gave the AZ sun an opportunity to turn it into a hot tub. It was quickly overrun by algae, and my wife's creative side let me know she disapproved...
Now we have an Aqualeader 18' round. Parisien I think. Metal rails and posts, so no salt water here.
She was insistent that we needed to get a pool. I was very reluctant to drop the $ needed to get an in ground pool.
She got busy and found a $30 pool on Craigslist. Yep. $30. It had some broken plastic pieces and the liner was trash, but it was otherwise good.
We actually spent more on the 4x8 u-haul trailer and trailer light converter kit than the pool.
$330 to buy a 3D printer to create replacements for the broken resin parts.
8 hours to redesign and tweak my version of the resin parts.
10 hours to print EACH replacement part in ABS.
$600 to pay a professional to rip out the swing set, curbing and to grade an area for the pool.
$150 for a new liner.
$80 for a pad under the liner
$70 for a solar cover
$?? for miscellaneous stuff that keeps on coming.
I've lost count, but it's a boatload less than what it would cost to buy a new pool outright and get it professionally installed.
Wife is happy... ultimately, that's all that matters (oh, and I got a 3D printer... WOOT!).
Thanks for reading,
