Hot Tub Foundation

5970 Views 3 Replies 4 Participants Last post by  Daniel Holzman
Hello everyone!
I am getting a hot tub and am building a foundation for it. I need opinions to see if this will work.

I bought (4) 8' treated 2X4 and will use a total of 12 galvanized nails to make a box out of them to sit on top of the ground. Then, I am going to pour pea gravel inside the box (and make it level.) I am going to put treated plywood on top of the pea gravel and the hot tub will sit on top of that. Any reason for this not to work?

Thanks all!

doesn't the tub manufacturer have support specs for your unit ? if it were me, i wouldn't bother w/the plywood & substitute compactible granular base ( any quarry ),,, pea stone shifts & can't be satisfactorily compacted,,, you've already considered existing soils condition/type & susceptibility to freeze/that, correct ? that's MY opinion :yes:
