swim spa requires 3 1/2" concrete - any alternatives?

[Guest Caroline]

For a swim spa, they recommend 3 1/2' of concrete. If we put it in our garage temporarily, then that's not a problem. But if we decide to put it elsewhere, is there an alternative to pouring concrete? Something more temporary? We may be selling our house within a couple years, and I want to take the swim spa with us, so I don't want to have to do anything too major.

Thanks much!

You absolutely need concrete. I don't think that 3.5 inches is even enough.

I do know that D1 requires 6 inches for there swim spas. you might want to check with other companys to be sure.

if your concerned about moving, just keep it the garage and use the hell out of it. Concrete is a must, and I'd also check with your local building official.
