Or do we?
Briefly, I had a standard blue liner/white frame Intex for the last two seasons, set up in two different locations on two different soil types. No problems with just setting the feet on top of the blue tarp on top of solid ground. I won't say I never thought of putting them on something like a paver during assembly, but never did I regret not having them.
Now I prepping for a larger Intex Ultra Frame, and while I've already taken this forum's advice about using some XPS foam underlayment, I'm more skeptical about the pavers, mainly because I'm only using 1/4" foam and I don't want to have to bury the more than 1" thick pavers to be level with the foam. Plus the fact that I'm using Deck Blok to build my deck, and they are going to be as close to the pool's legs as possible. I'm thinking of last year's tarp over the dirt, topped by the foam and the new tarp, with the pool and its legs/feet on top of all that.
I do plan to leave the pool up year round. Am I asking for trouble without the pavers?
