Hot Tub Deck Installation: Weight, Material, Treating

There are several property locations where you might consider placing an outdoor hot tub, and one of the most common and well-used among various hot tub owners is a deck or patio. Combining access to your home itself with fantastic views and some fresh air, placing a hot tub on a deck is a great move in many cases — as long as you’re going about it properly, that is.

At Hot Tub Factory Outlet, we’re proud to not only stock a huge variety of the best hot tubs around, including carrying major hot tub brands like Sundance and Viking, but also to assist clients with important concepts like these. Here are some various tips we often provide to clients on installing a hot tub on a deck, across this two-part blog series.

Determine Weight Capacity

First and foremost, in many cases before you even purchase the hot tub in question, you’ll want to make sure that your deck is equipped to handle its weight once it’s full of water. A standard rule of thumb for most empty hot tubs is that they’ll weigh about 40-45 lbs. per square foot when filled; so, if you have a 200 sq. ft. deck, that means you’ll need a deck that can support at least 8,000 lbs. Once you factor in the weight of the people who’ll be using it, you should tack on an additional 500-1,000 lbs. to that number for safety.

If your deck is made of wood, you might be able to increase its weight capacity by adding some extra support posts or crossbeams, but if it’s made of concrete, you might be out of luck. In that case, you’ll either need to look into alternatives like placing your hot tub on a ground-level patio or another solid surface, or investigating a lighter hot tub model.

Condition of Deck Material

As you’re considering what material your deck is made of, you should also give some thought to its current condition. If it’s an older wooden deck, for example, you’ll want to make sure that the wood is still in good enough condition to support a hot tub and all the weight that comes with it. This means checking for any rotting, warping, or otherwise weak or damaged boards, and replacing them as necessary.

The last thing you want is for your hot tub to come crashing through the deck because of a faulty support beam! If your deck is made of composite material or another non-wooden substance, you’ll still want to inspect it for any cracks, holes, or other forms of damage.

Treat the Surface

If your above inspection of the deck went well and you’re confident in its strength and stability, the next step is to make sure the surface can adequately protect your hot tub from any damage.

If your deck is made of wood, you’ll want to make sure it’s properly sealed so that water won’t be able to seep in and cause any damage or rot. You should also consider placing a mat under the hot tub to further protect the surface of the deck.

For composite decks, you’ll still want to use a mat for extra protection, but you won’t need to worry about sealing the material. However, it’s still important to make sure that any debris or dirt is cleaned up regularly.
