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.
Now you should abide by the following 3 rules of thumb:
- Your tub must not be close to any power line. Never place your hot tub near an electric outlet
- The foundation under the hot tub must be very strong
- The foundation has to be level
Now these are the 3 most commonly used foundation types for a hot tub
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.
2. Concrete pad
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;
- It must be level. This is to avoid any kind of settling after you install your tub.
- The thickness of your concrete pad must be within the specified limit allowed in the community where you live, provided there is any law that relates to the construction and installation of tubs in that community. If there are no such laws, the concrete pad must have a minimum thickness of 4 inches. This is to adequately support the weight of the tub, the weight of the water to be put in the tub and the weight of the persons that will be making use of the tub.
- The size of the pad should be approximately equal to the size of the tub. This is to conquer any accessibility issue.
While the following two characteristics have nothing to do with the construction of the foundation, they are equally important…
- You should have constructed your concrete and ensure that the concrete would have dried before the delivery of your tub. This is important because you can immediately install your tub and start making use of it right away.
- If you find any or all of the construction characteristics stated above to be intimidating, you can call on any home improvement service provider in your neighborhood. If this service is not readily available, you can collaborate with your plumber and work it out together.
3. Crushed gravel or stone
This type of foundation is recommended especially if your tub is to be situated outside.
This foundation must have the following characteristics;
- It must have a minimum thickness of 4 inches
- You must construct a frame around it to keep the foundation perfectly in place
- it must have a proper channel for drainage so that your tub would be durable
The following recommendation has nothing to do with the foundation but it is also important;
- Try to install low-level showers around the tub. This is to ensure that you can wash your feet before entering the tub which will prevent dirt in the tub.
