So you are now prepared to install your portable hot tub. You understand the benefits of having a tub in the house, you have done your research and have found the right choice that you deem perfect for you.
The grass is definitely one of the most used surfaces under a blow-up hot tub. And why not? If not contaminated with broken glass or wooden sticks, it makes an awesome cushioning material.
However, the ordinary ground is not such a good insulator. Try to use a ground cloth or an air mat under the hot tub, both for heat insulation and puncture protection.
This type of foundation is recommended whether or not your tub is an outdoor one or an indoor one. Your concrete pad must have the following characteristics;
While the following two characteristics have nothing to do with the construction of the foundation, they are equally important:
This type of foundation is recommended especially if your tub is to be situated outside.

The following recommendation has nothing to do with the foundation but it is also important;

These are recommended for either outdoor or indoor tubs. They have the following advantages over the other types of foundations;
Their pieces interlock. This means that…
First and foremost, the area on which you place your hot tub needs to be completely flat. If you place it on a surface with even a slight slope, the tub’s structural integrity will be compromised, and it is likely that it will collapse if filled with enough water.
To keep this from happening, pay close attention when you fill the tub. If you notice that water starts to flow more to one side, or if the walls start to bulge in a certain direction, you will need to move the tub to another location.
In addition to being level, the surface beneath an inflatable hot tub must also be sturdy and firm. Once filled with water, the tub will weigh quite a lot, and this weight will shift around as people get in and out of the tub. You should thus avoid muddy or sandy surfaces that might not provide the support an inflatable tub needs. Opt for placing your tub on the pavement, or a concrete deck.
Water drainage is another important consideration. Splashing will happen when people use the tub, even if it’s unintentional, and you need to be able to deal with spills with minimum fuss. You also wouldn’t want to have some difficulty when the time comes to empty the tub. For this reason, it is usually best to keep your tub on a surface where water drains easily.
This usually means setting up your portable hot tub outdoors, but an indoor area that meets this requirement will also be suitable. If you believe your hot tub is leaking check out how to find the leak.
Whatever surface you settle on, it is best practice to lay a cloth or ground mat underneath the portable hot tub. In addition to protecting the bottom of the tub, this will also minimize water damage to the surface it is on.

Ihave just purchased an inflatable hot tub and unfortunately… I live on a sand dune! My entire garden is sandy foundations with the odd clump of grass scattered. I would ideally like to place it outside BUT with a sand foundation and a rental house… I don’t think this is an option (unless you have an insight?). HOWEVER, I do have a large garage but I am concerned about ventilation and also the garage is sued as a workshop which is less than ideal for a clear hot tub. I am a bit lost and stuck with what to do! Any suggestions?
what type of mat & thickness
Like the previous person in 2020 i have just spent a lot of money on a patio and artificial grass. Mya daughter has bought a Intex 4 person octagon hot tub but both the patio and artificial grass area are sloped. On the grass it is 4cm over the length of the tub and on the patio it is 12 cm. I am looking for something that like the spa is portable and isn’t ridiculously expensive. I have looked but there is very little on the web about how to do this can you help please
can you put a hot tub directly on a wood deck
Can I use indoor outdoor carpet on top of 4” of gravel as a good base
Yeah, that sounds fine to me. 🙂
We want to put this on bare ground (some grass) next to the house, but it’s slightly pitched away from the house….not majorly, but enough to cause issue.
Thinking about boxing it out and putting a layer of sand down, but haven’t heard of anyone doing this. Are there any concerns you can think of doing it this way?
Hey! That sounds like a great idea. I don’t see any issues with that approach.
what type of ground mat? my spa is indoors inflatable on a level concrete floor
If I’m putting an inflatable hot tub on a level concrete patio, do I still need to put something under it?
hi i have wood chips on top of mud could i put a lazy spa on this or put some sort of mates u der neath it first
What can be placed under an inflatable hot tub to stop wooden deck rotting is there a pad like the interlocking one’s that are mesh like construction and act like under mattress aerators
What about artificial grass
Should be good to go, but not sure it will survive the weight of the hot tub.
Hi, If I have a gravel base, with pallets on top – then decking board, do I need to compact?
Can I put my lazy spa inflatable on to grass?
Hi. I live in rented accomodation and my landlord has just paid A LOT of money on a brand new rear garden. Unforfunately, he demolished the tiled conservatory where we had our LayZ Spa Miami. We have a lovely new paved area perfect for our hot tub, the problem is though, it isnt level. It slopes at a gentle gradient to allow for drainage. As we dont own the property we cant make any changes to the garden, so im in need of some means to create a level surface for the hot tub to sit on, but ideally be moveable. I was thinking of something like a wooden plinth or platform, fitting together in 4 sections or something like that, but i dont know if it would be strong enough. Ive also looked around the internet for some ideas but cant really find anything that doesnt involve butchering our new garden. Any recommendations?
Hi we’ve just ordered an inflatable spa for 6 people. We are going to position it on the grass as my patio isn’t wise enough. Is it ok to be put on grass or do I need to put some concrete flags down 1st
Hi there! It’s okay, but I would use some kind of mat or an old carpet under it to protect from rocks or sticks, just like people do with above ground pools.
Got 20mil gravel 6 inch thick can I put a hot tub on top of this for a base .please
Hey! Not sure what hot tub exactly are we talking about, but if it’s an inflatable one, I would definitely use some kind of mat between the gravel and the hot tub
Hi can I use concrete paving slabs for inflatable lazy spa ? These are 5cms thick but I’m reading I should have a base which is 4 inches ? Thanks
Hi Pauline! Sorry for the misinformation, we’ve fixed it. The 5cm pads will do just fine. While the hot tub can be heavy, the weight is evenly spread out by the water.
Can I put my inflatable hot tub on a small deck that sits on the ground?
Absolutely! Just make sure it’s sturdy enough to carry the weight of the filled hot tub.
Where can I find that wood type interlocking pieces mat for under my hot tub???????
Hey! Here’s something like that: https://amzn.to/2POXv72
Just search for interlocking wooden tiles, you’ll find plenty 😉
