I'm planning on pouring a 7x7 concrete pad for a hot tub. I dont know exactly what type of concrete to buy and do i need to re-enforce the 4" of concrete any further. I'm planning on just digging into the ground 4 inches and then filling it up with the concrete. Dont care how it looks because the hot tub will be surrounded by a deck and you wont see the bottom.

My brother and I did this two years ago for his "tubby" in the California Sierra Nevada foothills
We went down to clay (3"), put down an inch of pea-gravel, put up a 2x4 pour frame, suspended wire mesh at half-depth, poured the concrete, screeded and finished the surface
That has lasted just fine for two icy and snowy winters with a FULL tubby. We plan to do the deck this winter, since we have had other projects sucking away money (barn and fencing, irrigation, and a swamp-cooler).
Good Luck !!

There was a similar question earlier today, if I were doing this, i would dig to clay, put landscaping fabric in, hardcore and 6" concrete with iron mesh through it, better safe than sorry, 6 people, a hot tub and water at 2 pound a pint in weight is a lot of weight.

this will take a little over a half yard. so mix it yourself. a truck would be cost prohibitive unless you can find someone pouring and they have some left on the truck. i would put some mesh in it and go a little deeper than 4 in. for the hole so you can get some crushed stone under the slab...quikrete makes a pretty good mix for diy projects...

certainly can't hurt.
Consider the fact that water weighs 8.5 pounds per gallon.
What possible harm can it do to add support, even go 6 inches for the slab. The cost and labor will be minimal.

No, but you will need at least a wire mesh. You can probably get it where you're buying the cement. The ground underneath will settle, the mesh keeps the cement from coming apart.
