If you too are searching for something that allows your family to relax, have fun and play around, then this can be the most optimal choice for you. They can not only hold enormous quantities of water but are also very kid-friendly so that even your smallest children can enjoy them a lot.

If the thought of having one of these inflatable hot tubs pleases you, you can visit here to know more about them. Those who have bought it, however, while they are happy with their purchase they are stuck with a dilemma they don’t know how to resolve – what should be put under the tub?

They have a sturdy framework but if they aren’t placed under a suitable base, their lining can face damage and wear out prematurely. Even before you can fully enjoy your inflatable hot tub, it will get worn out, leaving you with a bitter taste in your mouth for purchasing it.

That’s why if you want to maintain the structural integrity of your tub while enjoying it as much as possible, you are required to put it on a proper base. In this article, we’ll be discussing exactly that with several basing alternatives for you to decide from.

1. Nothing but grass!


You’d be surprised that one of the most frequently used and ideal surfaces for an inflatable hot tub is actually grass! Any type of grass, as a matter of fact, even in the ones in your yard or a nearby field. As long as the grass is not littered with sharp objects or rough rocks, you are good to go. However, many experts including ourselves would actually recommend you to not place your inflatable hot tub directly on the ground even if it’s covered with grass.

This is because the grass we have in our backyard isn’t exactly perfect land with an entirely smooth surface without any point objects. Even something like a needle that may have dropped when you were knitting sweaters outside can leave your inflatable hot tub’s integrity vulnerable. That is why we recommend getting a ground mat or cloth that can sustain sufficient damage for your tub and also avoid getting your ground muddy in case water splashes out, which it will when you have kids playing inside it.

2. Smooth and firm concrete pads

Considered by many as the perfect base solution for putting your inflatable hot tub on, a base and groundwork made from concrete pads performs its duty quite well. These surfaces can need considerable work to install, especially if you are doing it inside your home. They may also feel a bit unnecessary since you are spending a considerable amount on something that’s just going to act as a foundation for your tub.

However, in reality, concrete pads have considerable benefits attached to them. One of the prime benefits is that they provide an amazing non-absorbent surface with friction so that you can safely go in and out. However, there are also certain things that you need to ensure with them. Firstly, they should be adequately leveled, as an uneven surface may cause your tub to tumble down. Secondly, they should at least have the same thickness as the tub.

3. Crushed gravel


Sand and dirt aren’t really recommended to be the perfect foundations for your tub, but it doesn’t change the fact that walking through fine grainy land and then going in the water is one of the most blissful feelings in the world. However, there is one base foundation that feels the closest to sand and can serve as the most optimal and desired groundwork for your needs – gravel.

Crushed gravel is a favorite base for many people due to the reasons stated above and if you want a mini beach of your own at your home, you can consider having it too! However there are certain things that you need to ensure if you wish to have a crushed gravel base, or otherwise, you can severely damage your precious hot tub.

Fine gravel is very absorbent and unless you want to play around in the mud, installing drains around your hot tub is heavily recommended. The gravel should have the bare minimum thickness of about 3-5 inches, or it would be unable to accommodate the entire weight of a filled tub. You can consider adding a supportive structure of your own beneath it, to support it further.

4. Synthetic tub pads

These synthetic tub pads are gaining a lot of attention lately because of the sheer utility they provide to anyone who buys them. Firstly, they come in tremendous color options so you can choose from any color and style you want that matches your hot tub and landscape. Additionally, they require zero maintenance as they are entirely factory-made from silicone.

This also makes them a wonderful alternative if you are searching for something that is straightforward to install and remove. This allows your inflated hot tub some semblance of mobility and you get the opportunity to set the tub up in any spot you want – even inside your home!  Their lightweight and synthetic material also allows them to be way cheaper than the other options in this list.

5. Additional tips for placing down your hot tub


Apart from considering your foundation you need to be well prepared about other things as well. Is the location you are installing your tub in not perfectly horizontal? Is the water leaning towards one particular side? If so, installing your tub in this location can prove fatal to you as well as the inflated tub.

Apart from that, is there a space for drainage or is there ground to absorb the water? If not, then it might cause the residual water that comes out from splashing, to store up and cause algae production if it stays like that for too long.


There are numerous groundwork bases that can easily be utilized by your tub. Along with them, several things are also required to be considered. If this guide helped you with that, please consider following our website for regular updates as it will help us out immensely.
