... Does anyone have their tub on a 2 foot high "slab"? If you do, how much did it cost to do?
A neighbor got a hot tub and it's in the air on concrete. My wife said she believes it's mostly cinder blocks. I can't see the lines of any cinder blocks from my backyard ... maybe binoculars will do the trick ... I'll wait until they use the tub, it'll freak them out!
It looks like they'll surround it by expanding their deck.
It never even occured to me to raise the tub that high by putting it on concrete.

Why would anyone in their right mind even want something so high, you would need a ladder to get in. Vinny, can't you take a picture of it and post it? That has to look ridiculous.
Just my opinion!!

If your trying to get it up to deck level to build access to it from a deck instead of the ground it's a great ides. But I would hope they used filler of some sort.

Well, I won't take a picture of a neighbor's place ... to me it's not right.
What Tman said is I believe is what's happening, they raised their slab to deck level, I too had my tub up in the air for about 3 weeks as I finished off the deck, but instead of solid concrete I used a deck.
I was curious about having a tub that high on concrete vs a deck, I would think that their dealer (assuming they went that route) could have given them better advice ... it must have cost a fortune to build.
And I agree that I hope they filled it in.

That's a lot of concrete.
You would think that building a wooden deck/platform for the hot tub would have been more economical (or at least used cinderblocks).
I'm sure you'll find your way over to their house being that you both have a hot tub (seems only natural that there will be a conversation or two where you guys start talking about hot tubs).

Vinny, I am very familar with subfloors due to my job as a tile and marble setter. That is way to thick of a slab. I say this because over a certain thickness you actually weaken the concrete. Unless they used steel foundation beams for support they will definitely have alot of problems. Heck, a basement slab is only 12'' max for most homes. More is not always better, especially when dealing with poorly foundationed concrete. I would love to know more it if you hear or see anything.

IT's probably block w/ a 4-6" max concrete slab poured over - kind of like the foundation for a slab-built house. Set the forms for it to cover the block to give it a monolithic look

BTW, 8x8' @ 24" thick would take about 5 yards of concrete (~1/2 of a standard mixer truck) - enough to do a 20 x 20' 4" pad. I can't see a contractor doing this w/o offering much better solutions for project cost and ease of installation.
-
It sounds like they poured a small foundation around the perimeter, filled the inside with gravel and poured a slab on top. Seems solid.

ya mean kinda like dis?

I built a little "mini deck" as a platform for mine.. used 9 pier blocks and built it out of 2x8 treated on 16" centers and decked it with 5/4 6" treated decking where the hot tub sits, and composite (which I used on my deck) around it and to trim it off. I raised it so the top is 14" above my deck. If I hadnt, then I would have had to buy some kind of railing to use to get in.. now I use the side of the tub as a "handrail" when I climb down into it.. works very nicely.

A thought of a 8'x8' (or 7'x7') concrete block 2' high seems out of place and expensive. I guess it may be a viable alternative but would have thought a deck is easier and cheaper.
I built a deck for the tub with 6 concrete footings for it and used 6x6's as uprights and all 2x10's for the framing. As I said, I wouldn't have thought of making something that tall out of concrete.
