Do I need a special foundation to support this tub? Like a 4" thick concrete slab?

I have ours on our back porch which is a several inch thick slab, but I would think as long as it is level and won't sink, anything would work. Total weight around 1 ton.

You need a surface capable of supporting about 2,500 lbs over about a 6x8' space. That is testing the limits of a traditional deck. about 2000 lbs of water, 250 lbs of two people, and 250lbs of the hot tub itself.

I just leveled out a spot in the backyard put some sand down to level and placed the tub on it, it worked fine. Although the tub is heavy, the weight Is spread out over several square feet so no problem.

I put mine on a deck foundation using 2 by 6's for support and then deck boards on that. I did put 4X4's in concrete on all 4 corners and bolted the 2X6's to the 4X4's. Make your wood deck sturdy and keep working to keep it level and you should have no problems supporting the weight.

I don't use foundation but I would put the tightner on first. Make sure you really shake tub for awhile otherwise it leaves a residue you have to dab off

Our tub was very similar. I went to a local hardware store to get a metal pipe that would fit into the shower rod at each end, connecting to the wall. This extended the length of the shower rod out to meet the width of the tub. I did later order extra ceiling supports for stability since it only came with one.

It needs a foundation. I put it in a RV with a platform and didn't need a boxspring. If you use it on a regular bedframe you will need a boxspring.

You might need thicker underlayment for the second floor.I am using this in the 1st floor, so far OK.

The frame uses the walls of the shed as a border, the frame is light and there is a big gap between the frame and door area, I don't think the walls or frame would hold concrete in. I think pouring a slab first would alleviate the need for the frame completely.

I don't know if that is advisable or not. I know mine is installed in cement and in an inground pool. I do know that you want it installed so that it can support the weight of the person(s) coming out. It would have to be very well reinforced with extra framing for stability.

No, you will need some kind of support for the waterBob to function as designed/intended. Your bathtub is the ideal location for the waterBob.

I feel that it would have been sturdy enough without the tub surrounding it. Fill it with enough air and it should be fine.

Should be placed on 12-12 inch concrete slabs and should be anchored by placing rods on 4 corners anchored in 4-6 inches of concrete.

I used the thicker version because I was installing on 3/4" USB over 20" spaced joists. That's due to potential floor flex. On a slab I would have used the thinner (cheaper) version. Some people use the thick version to better match other parts of their floors (like wood floors)

Just go on, and buy a stronger and longer screws as I do. For concrete you have to use special dowel.

the area under the pool does need to be very level, I used sand on my first pool, but later took it out and poured a concrete slab to make it easier.

I would highly recommend a sturdy platform of wood, concrete, or patio blocks but a well tamped and leveled gravel foundation would work. The floor is flexible and snaps together and acts as a base for the walls so it must be stable and level. Hope this helps.

Do not use 4x4s unless your height is no more than 4 ft off the ground. a unit of this size will require support columns like a schedule 40 pipe 4 in in diameter or more embedded in 3 by 3 ft concrete footings at least.

We live in California and put our tub on a concrete patio. We bought a sheet of hard foam that was about an inch thick and then put the pad that came with the tub on top of that. It pads it nicely and insulates a bit. Very comfy, just expensive to keep it heated to 100 degrees.

I just use it for the foam bed. No foundation because it will not raise or lower since most foundations are made of wood framing.
