The backyard is a safe and private sanctuary, something that should be enjoyed in the evenings after a long day of work or in the morning before the kids are off to school. It’s a place where relaxation and luxury go hand in hand. Hot tubs can be fabulous additions to the home, but maximizing your backyard space to accommodate for it is key. Some deck designs can be built around a hot tub, depending on its size and capacity. Once you figure out how to make your deck and hot tub work together in harmony, you can choose how you want it to look.

Check out our quick hot tub design guide below, and then take a look at our favorite hot tub deck ideas that will help you enjoy your backyard in style.

How To Determine If A Deck Can Support A Hot Tub

Naturally, you want to inspect your deck to ensure it can hold a fair amount of weight. If it can’t, there are ways to add the proper amount of support. Decks are one of the most common (and most preferred) backyard locations for a hot tub, and there are ways to carefully plan for its structural integrity so that all is done safely.

The Formula

There is actually a specific formula that can help you determine the weight of your spa, and whether your deck is supported enough to hold it:

[Weight of Hot Tub + (Number of Gallons of Water in Your Tub x 8.34lbs) + (Number of Total People Hot Tub Can Seat x 175lbs)] / Number of Total Square Feet of Your Tub = Your Pounds Per Square Foot

There can be extra factors and variations added by the manufacturer, or by the professional contractor you’re speaking with. This is just a general mathematical formula to determine weight at the baseline, but other considerations are needed. This is especially true if your deck is already elevated, or if you plan on elevating it while installing a built-in hot tub.

The Rule of Thumb

It’s always recommended to check with the hot tub’s manufacturer for specific weight information first. It is also to speak with a renovation expert about the status of your deck before starting any projects on your own.

That being said, it is generally understood that decks situated just a few feet above the ground can hold roughly 100 pounds per square foot. If your hot tub’s manufacturer lets you know that the hot tub weighs less than 100 pounds per square foot (filled with water, of course), then you do not need to worry about adding extra reinforcements.

Extra Considerations

Of course, it’s important to consider extra weight factors such as yourself and your family while you enjoy the tub. Typically, the manufacturer takes this into account when giving you the numbers. But if you still aren’t feeling completely confident with how to reinforce a deck for a hot tub, you are encouraged to reach out to a contractor who can help you further your deck specifications for a safe – and stylish – spa construction.
