Most of us have owned a hot tube at least once in our lifetime and most of them are normally placed onto a stone or concrete base.

So, the question is, “can you place a hot tub on a deck?” The answer is yes, but there are certain things you should take into consideration before doing so. The most important thing for us to consider is the safety of you and your family.

There are a few things you should do to make sure your deck can support the weight of a hot tub:

Placing a Hot Tub on Your Deck

The first thing to consider is the weight of the tub when it’s full of water and people. Most hot tubs weigh around 2,000 pounds when they’re empty and can hold 300 to 500 gallons of water.

This means that when the tub is full, it could weigh as much as 5,000 pounds or more. So, you need to make sure your deck can support that kind of weight.

If you have a deck that’s made of wood, you need to make sure the posts and joists are strong enough to support the weight of the tub.

Most decks are built to support a snow load of 20 pounds per square foot, but a hot tub can weigh up to 60 pounds per square foot.

So, if you want to put a hot tub on your deck, you

Yes, you may have a hot tub on your deck. Decks up to 2 feet above ground level can support up to 100 pounds per square foot; this is enough for most hot tubs. However, decks 2 feet or higher will require more structural support.

The additional support pillars should be no more than 30 inches apart and ideally installed in reinforced concrete.

Can You Put A Hot Tub On A Second Floor Deck?

If you’re wondering whether you can put a hot tub on a second floor deck, the answer is “Yes”.

However, I would recommend that you have the deck structure inspected by a qualified contractor to be sure the deck can support the weight of a full hot tub.

Keep in mind that most hot tubs weigh between 2000 and 3000 pounds when they are empty, but full hot tubs can weigh as much as 5000 pounds.

So you will need to make sure your deck is built to support that much weight.

Age of the deck

It’s not just the weight of the tub that you need to take into account when deciding whether to put a hot tub on your deck. You also need to consider the age of the deck.

If your deck is more than 10 years old, it is best to have it inspected by a qualified contractor before adding a hot tub. This is because older decks may not be able to support the weight of a hot tub, and they may also have rot or other problems that could cause the deck to collapse.

decks constructed from the ground up to 2 feet above ground level can withstand up to 100 pounds per square foot; enough for most hot tubs. However, decks built 2 feet or more above the ground will require extra support.

Alternative – A Recessed Hot Tub

If you’re worried about the weight of a hot tub on your deck, or if your deck is more than 10 years old, you may want to consider installing a recessed hot tub.

A recessed hot tub is installed in the ground, and only the top of the tub is visible. This means that the weight of the tub is supported by the ground, not by the deck.

Installing a recessed hot tub is more expensive than installing a regular hot tub on a deck, but it is a good option if you’re worried about the weight of the hot tub.

Joist Spacing For Hot Tub Deck

For wooden decks, the typical joist spacing is 16 inches on center and for composite decks, it’s 12 inches on center.

If you have a deck with a different joist spacing, you’ll need to adjust the supports accordingly. The distance between the supports should not be more than 30 inches.

You also need to make sure that the posts and joists are strong enough to support the weight of the tub.

A snow load of 50 pounds per square foot is typical for most decks, but a hot tub can weigh up to 60 pounds per square foot.

So if you want to put a hot tub on your deck, you need to make sure the deck is strong enough to support the weight of the tub.

Additionally, you’ll need to make sure that the distance between the supports is no more than 30 inches.

This is because hot tubs are very heavy, and the supports need to be close together to prevent the deck from collapsing.

If you have any concerns about whether your deck can support a hot tub, it’s best to consult with a qualified contractor.

They will be able to assess your deck and determine if it is strong enough to support a hot tub.

How Much Does It Cost To Reinforce A Deck For A Hot Tub?

You would think that the cost to reinforce your decking would be cheap, but it actually isn’t.

To reinforce your deck for a hot tub, you’ll need to add additional supports and joists. This will typically cost between $500 and $1000.

Additionally, you’ll need to have the deck inspected by a qualified contractor to make sure it is strong enough to support the weight of the tub.

This inspection will typically cost between $200 and $500.

So the total cost of reinforcing your deck for a hot tub will be between $700 and $1500.

This is a significant investment, but it is worth it if you want to avoid the deck collapsing and injuring yourself or damaging your hot tub.

FAQs

Is it necessary to reinforce the deck for a hot tub?

Decks will require reinforcement to support a larger hot tub if the chart does not account for loads of 50 pounds per square foot. Fortunately, there are online deck load calculators that may assist you in changing your joist span and dimensions to accommodate a greater weight.

Will a hot tub rot a deck?

It all depends on the material used to build the decking. If you have installed your decking with either PVC or a composite material, then you have nothing to worry about in terms of rot. On the other hand, if your deck is made out of wood, there is a chance that the hot tub could cause the wood to rot over time. If you don’t use a sealant, the hot tub will eventually rot away your deck. To prevent this from happening, apply a sealer to the wood before installing the hot tub. This will create a barrier between the wood and the water, which will aid in the prevention of decay.

Is a sunken hot spa right for me?

If you are worried about the weight of your hot tub on your deck, then a sunken or recessed hot tub is a great option. A sunken hot tub is one in which the weight rests on the ground rather than on the deck. A sunken hot tub is more expensive to install than a standard hot tub, but it’s an excellent choice.

Can I put a hot tub on my balcony?

If you’re installing a hot tub on a balcony, in an apartment building, or on a rooftop deck, you’ll have to make modifications for proper drainage. Because high-rise buildings are built with cement, masonry, and steel reinforcements, outdoor surfaces shouldn’t be exposed to hot tub steam.
