Gravel/sand/paver Base For Hot Tub?

[Dizzyfun]

First, I had considered concrete slab for out hot tub but the price of concrete is crazy in our area. For our new hot tub I am considering a base made from a few inches of pea gravel topped with 1-2" of sand then concrete pavers. Holding it all in I was thinking of 4"x4" pressure treated wood. Is 4x4 sufficient or should I use something else?

For an 8' tub, is the 3" of gravel, 2" sand and pavers sufficient? Or do the depths need tweaking at all?

Thanks.

I used preaure treated 2"x4"'x8' planted in the ground about 3 inches and used 16 wood stakes to hold in place the dug out the inside 4 inches and filled with5/16 pea gravel. My hround is very hard level and stable. So far no pronlem. i also did not want to lay a concreate slab for other reasons including price. price for the gravel was $48 delivered to my driveway for a yard only needed about 3/4 of it.

So much depends on the ground... If it is packed and firm then what you propose is fine... I usually use quarter minus (crusher dust)about 4-6" and well tamped then drop on the patio stones (concrete pavers) and you are as good as it gets again providing the ground is solid and well settled...
