How Much Does a Hot Tub Weigh?

How Much Does a Hot Tub Weigh?

If you’re in the market for a new hot tub, get excited! Hot tubs are fun, relaxing, and have a long list of incredible wellness benefits. But before choosing a hot tub, there are a few factors to consider. At Energy Center-Manhattan Pool, we believe one especially important question to consider is how much does a hot tub weigh? The short answer is it weighs a lot! Let us give some more details and explain how this impacts your hot tub choices.

What is the Average Weight of a Hot Tub?

When determining the weight of a hot tub, there are actually two correct answers. One is the dry weight and the other is the filled weight, or how much it weighs when full of water. You need to know both answers for proper and safe installation.

As an example, the Hot Spring® Grandee® is the largest spa in the Highlife® collection. It has a dry weight of 940 pounds but a filled weight of 5,920 pounds. On the other end of the spectrum is the Jetsetter®, the smallest of the Highlife collection. It has a dry weight of 455 pounds and a filled weight of 2,650 pounds.

Keep in mind that filled weight accounts for both water weight and the weight for the maximum number of people the hot tub is able to hold.

Does Weight Matter for Location?

Absolutely! Before your hot tub arrives, you need to determine the location for your hot tub. Be certain to consider the size and weight of your spa as you do so. If you’d like help choosing the best location, our team can help you think through the various factors and decide on the best spot.


Thinking of placing your hot tub on a deck? Great! But before you do so, it’s important to calculate if this is safe. As a general rule of thumb, decks can typically hold 50 pounds of weight per square foot. Do the math to see if this would work for your desired deck space.

Bare Ground

We do not recommend installing a hot tub directly on the ground. The weight of your spa can cause the ground to shift and sink over time. It may even sink unevenly causing your hot tub to be tilted.

Concrete Pad

Instead of placing your hot tub directly on the ground, a better idea would be to place it on a concrete pad. This will help support the weight of your hot tub and prevent unwanted shifting. 

Inside Your House

Many hot tubs can be installed inside your house for convenient use. In addition to the water resistant flooring and property air circulation, you will want to make sure the area can properly support the weight of a hot tub. 

Does Weight Matter for Hot Tub Installation?

Of course it does! The dry weight amount will tell you how heavy the hot tub is to move. This is important to know if you plan to install the hot tub yourself or move it to a new location. And the filled weight will tell you if the area you are installing it on – deck, concrete pad, indoors – can support it.


Always consider how much your hot tub weighs so you can be safe and prepared for delivery and installation.
