Ready to install your dream hot tub but not sure where to start? There are a lot of options when constructing a hot tub base, each with its own advantages and disadvantages.
You’ll want to make sure you pick the right base material for your project. Read on to learn everything you need to know about hot tub gravel base.
What is the Best Base for Under a Hot Tub?
Hot tubs are often extremely heavy, often weighing upwards of 3000 pounds when filled. To ensure that your hot tub remains stable and supported, you’ll need to choose a good base material.
There are many options in base material when installing a hot tub. The best base material offers proper reinforcement and strength to support the hot tub. Gravel is the most stable and cost-effective base option.
Options for Hot Tub Placement
Concrete can be a great option, especially if your existing landscaping involves concrete. It is incredibly strong and will create long-lasting stability for your hot tub.
The biggest disadvantage to using concrete as a base is the lack of drainage it provides. Should you use concrete to support your hot tub, you’ll want to incorporate a drainage method.
Your existing wooden deck can be used as a base for your hot tub. With proper support, some decks are already load-bearing enough to install a hot tub. Check the strength and load-bearing potential of your deck to determine if you can use it for your base.
Keep in mind that, over time, wood from your deck can warp or rot. If this happens, your deck could lose its strength or become unlevel.
It is also possible to install a hot tub directly over patio stones, but there are some drawbacks. Similar to installing your hot tub over an existing wooden deck, you’ll need to have your patio inspected. An inspection will determine if your patio is strong enough to support the weight of your hot tub.
It is also an option to lay down new patio stones as a base for your hot tub. Consult with a construction expert to ensure that the patio stones are viable options for supporting the hot tub’s weight. It is crucial that patio stones for your base are laid down level.
Using Gravel as a Base
Gravel is one of the best base options because it offers numerous advantages at a cost-friendly price. It will create a solid base that evenly distributes the weight of a hot tub.
Gravel also provides an excellent drainage option. This will prevent any build-up of water or staining around your hot tub. The permeability of gravel is also beneficial in controlling rainfall and runoff.
Unlike other options, gravel offers great support, excellent drainage, and a level solution that will not bend or crack over time. Using gravel can give you the strength of concrete at a fraction of the price. 4’ or more of gravel in your base will create the same level of support as a concrete slab.
There are also structural benefits to using gravel. Even if you install gravel over an uneven surface, the crushed stone will create a level base.
Installation & Cost
Gravel is fairly easy to install. First, you’ll need to level and slightly excavate the ground. After removing the topsoil, install a wooden parameter slightly larger than your hot tub. Then you’re free to add in enough gravel to give you the stability you need.
Most of your costs when installing a hot tub gravel base will depend on what type of gravel you use. Consult an expert to determine what type of gravel will be best for your project.
How Much Gravel Do I Need for a Hot Tub Base?
The amount of gravel you’ll need to construct your base will depend on the size of your hot tub. Generally, you’ll want enough gravel to fill a space slightly larger than your hot tub with at least 4’ of gravel.
