I am going to install a hot tub and I am considering options for how to prepare the site for placement. The filled weight of the tub is around 6000 lbs. The hot tub supplier suggested a 4″ bed of packed stone dust under a deck made of 2×6 pressure treated with the joists on 8″ centers. I think that concrete is the best option but the homeowner is reluctant to let me put ina 4″ slab given that they may want to relandscape in a couple of years and want to avoid the possible demolition of a 4″ slab.
Does anyone have thoughts on this? Will the stonedust / deck option be adequate?
Thanks

You may try posting your question at Breaktime; I'm pretty sure they'll have lots of answers. I also think this or very similar questions have been asked before, so you may want to use the "advanced search" option to find discussions on "decks for hottubs" or some phrase like that.
At least, from what I understand, the joists (or sleepers) will rest on the ground, right? On gravel, but the gravel will be on the ground? Only thing that might be of concern would be frost if the gravel weren't drained (and if you even get frost where you live). Anyway, the people at Breaktime can give you good answers if you can't find them through the "search" function. [One question concerned a hottub the guy wanted to build something like nine feet off the ground!]
Thanks. My mistake on the location.
