6x6 on gravel vs 4x4 ?

Hi, When I built my base, over 12 years ago, I did something very similar. I just used 4x4's on a bed of gravel topped with 6' treated decking, (I would use Trex today) . Been absolutely fine with no issues or shifting at all. Still perfectly level  today.  I figure, as long as the wood is 100 percent supported underneath, the thickness should not make a difference.

Be sure to space them no more than 12 inches apart, for support, and intensely pack the gravel before hand.

I included a couple pics, too.

Nice pad. Well done.

When I make them I do the same for the most part but I build it to the exact size of the spa's base so it under cuts the side panels and water runs to the ground and not onto the wood frame work. Then back fill in between the joists with limestone screenings flush with the top edge of the wood frame to lock it in place and keep animals from living in the void. I thoroughly wet down the limestone and pack/tamp it place. The limestone will be just like concrete when dry. Then no need for a wood deck on top...unless you want a wood deck.
