Our vinyl lined pool, installed in early 2004, has polymer walls. We haven’t had any issues with them and I like that they will not rust over time (If I remember correctly they came with a lifetime guarantee).

my walls are plastic with pool krete for the floors. My pool was built 30 years ago so techniques may have changed but I don't have any structural issues even with lots of tree roots.

It seems to be a NY specialty, esp on LI, to build concrete walls for vinyl lined pools. I like it a lot and if I ever built one I'd get the cement walls.

I built my pool with cement, happy about the forever-ness. Things change and the house that we thought we'd be in forever is selling in a few weeks. Steel pools routinely last 40 years. At this point that is officially a 'lifetime' pool for me. If my builder will do it at a significant savings, I'll build with steel next time. If the cost is similar then concrete would win. Last time (8 years ago) nobody was doing steel but it seems to have gained popularity again. Probably because of the amount of freeform pools.
