How to buid a base for swim spa

[CarverStrone]

Hey all,

New to the forum and spas in general. Have had pools at various houses for years but just bought a new place and not wanting a pool we ordered a SwimSpa.

Its 14ft long and quite nice. Bigger than I expected in person. Anyway we have a lot of back yard space and a perfect location for it. The issue is that it's grassy back there. Fairly level but not perfectly. It was ready about a month or so ahead of schedule so its coming in 7 days. I need to get a level base down for it. My plan in the near future is to build a nice deck around it, but for now just a place they can set it and it can be used would do.

I'm quite handy and have all the tools needed I think I just don't know what the best way is to make sure its level. The deck around it will be raised but it's already super tall and don't need it raised so I'd be happy with it sitting on the ground as is if it was already level. But its just grass so its not pefectly level. I was thinking of a wooden base that sits on the ground and maybe anchor it with posts that are buried. They can come a few inches above the ground to ensure its level everywhere. I could pour concrete in there if needed but would prefer to keep it as simple as possible.

Or is it best to dig down a foot for the entire size and fill it with gravel?

Any suggestions? Thanks.

We put in a 15' foot swim spa 2 years ago. Most Swim spa companys will tell you you need to put down a 6-7 inch concrete base. If you have any other questions I'd be more than glad to help.

They said railyway ties and gravel would be fine.

Did you put the concrete in yourself?
