If you have recently purchased a hot tub and are preparing to install it, you may be thinking, ‘do I really need to make sure it’s level?’ - the short answer is yes.
There are many reasons why it is important to make sure that your hot tub is level, such as ensuring the safety of those who use it, as well as lengthening the service life.
Below, we’ve prepared a handy guide to get you ready for your hot tub installation date!
Keep reading below to find out why it is so important to have a level, strong foundation for your hot tub, as well as some recommendations for location preparation.
Why Should You Level a Hot Tub?
This is a valid question to ask. From wanting to get your hot tub installed as quickly as possible, to not having the time to find an even spot to locate it, it can be tempting to consider placing a hot tub on a slightly uneven surface. We get it.
However, cutting corners when deciding on an area to keep your hot tub is a bad idea for several reasons. You must make sure that your hot tub has a smooth, totally even base as, once a hot tub has been filled with water and people, it’s going to weigh thousands of pounds.
For this reason, if your hot tub is installed on an uneven foundation, over time, any surface dips on the ground will create stress on the hot tub structure. This will ultimately lead to cracking on the areas where unnecessary pressure is being exerted due to unevenness.
Also, another reason as to why it’s important to level your hot tub is so that it can properly drain itself correctly. If your hot tub is kept on a flat surface, water drainage is going to able to occur. If you keep your hot tub on a bumpy, uneven surface, it’s not going to be able to properly drain water.
How to Level a Hot Tub
First things first, you’re going to need to decide whether you want to do it yourself or reach out for the help of a professional.
Ideally, even if you have a level foundation that is suitable to safely serve as a foundation for your hot tub, we still recommend enlisting the help of a professional. Why not ask your local dealer for contractor recommendations in your area?
Though it will cost more, it means that a professional will be able to double-check the base and ensure that your hot tub will be properly level and not at risk of warping over time.
So, when should you level the area you want to keep your hot tub? If this is something you’re wondering, it’ll be a lot easier to judge than you might think.
Your judgment is going to be your best guide, however, here are some options you can take to make sure your hot tub’s base is going to be smooth and even:
Level Your Patio Concrete
Let’s say you’ve ordered your hot tub and have found that your concrete patio slab is not level and slopes slightly downwards away from your home.
Besides being normal (most patios are designed in this way so that rainwater can fall away from a house, as opposed to accumulating around it) it is problematic for keeping a hot tub. Therefore, If this happens to be the case for you, you’ll likely have to consider getting the concrete leveled.
Additionally, if your patio takes up a large portion of your yard and is bigger than the hot tub, you could also choose to measure out the section of the patio where the hot tub will be.
All you’ll have to do is create a guideline that fits around the perimeter of the tub, and then pour a new concrete slab over the existing patio.
Before doing this, you’ll want to make sure that the existing patio concrete is dry, clean, and slightly scratched up so that the new concrete will be able to more easily adhere to it.
Done correctly, you’ll have a perfectly even foundation to install your hot tub on. Remember, you can always reach out to a professional to do it for you if you’d like help.
Replace Your Patio Slab
Another way that you can ensure that your hot tub will be level is to completely remove existing grass or patio and re-pour new concrete into the area to make sure that it is totally level.
This method is the most time-consuming and expensive, although it’ll be a relatively simple job for handy homeowners that are into DIY, especially if you only have a plot of grass that you’d like to fill.
However, if you wish to replace the existing patio with new concrete, your best bet is to hire the help of a contractor. Digging up concrete is extremely tiring and strenuous, and a trained professional will be able to come in to do the hard work for you.
Alternatively, if you decide that you only want a certain area of the patio leveled out, a contractor will be able to drill holes into the slabs and then pump in a chemical mixture that will raise that section to level.
Opt for an Above Ground Hot Tub
If you don’t want to go to the hassle of measuring out patios or replacing them with new concrete, you could opt for an above ground hot tub as opposed to a standard one.
In regions where freezing temperatures occur, there is a risk of splashed water forming under the base and weakening the overall structure, causing it to shift and become uneven. The presence of a raised concrete slab will help to ensure that this doesn’t happen, all the while ensuring that the hot tub is even.
It will also help to protect the hot tub from exposure to dirt on the ground and means that you won’t have to dig up your garden or change your existing patio.
Though some people do use wood shims to level out their hot tub foundations, we don’t recommend doing this. The base of your hot tub needs to be supported fully, and using wood shims will not provide enough support and split over time.
Regardless of which method you decide to take to level out your base, the surface that your hot tub sits upon should be firm, supportive, and able to withstand the weight of your hot tub when filled to capacity so that you’re free to safely fill the tub with hot water, kick back and enjoy!
