Why Does Hot Tub Weight Matter?
If you’re looking to install a hot tub in your home, there are multiple reasons that the weight could be an issue.
There are hot tub pad requirements to consider, or you may be wondering if you can put a hot tub on your deck.
The last thing you need is your concrete to crack under the weight which could cause problems in the structure of your hot tub, potentially rendering it useless.
Having your hot tub fall through your deck wouldn't be fun either. If you'd like to avoid this, read our article titled How To Determine If A Deck Can Support A Hot Tub.

But another consideration might be the installation itself. If your hot tub gets delivered to your home, will you have the proper tools, strength, or help to get it into your yard?
Maybe you foresee yourself moving within the next few years and you’re wondering if you’ll be able to take your hot tub with you when you’re ready.

How Much Does An Empty Hot Tub Weigh?
So we know that no two hot tubs are the same. Although come in a wide variety of shapes and sizes, we can typically estimate the overall average hot tub weight depending on the capacity.
A small hot tub, one that holds anywhere from 2-3 people, will usually hover anywhere from 300-500 pounds.
On the other hand, larger hot tubs, those that hold anywhere from 5-7 people, usually hover closer to 1000 pounds.
Anything in the middle will usually hover around 700, as you could’ve guessed, hot tubs that are larger can easily weigh up to 1,500 pounds or more.
Do keep in mind that these are all rough estimates, If you have a particular model in mind, we recommend looking up that particular model to see the dry weight specs.
How Much Does A Full Hot Tub Weigh?
There are a few things that you need to know before trying to figure out the weight of a hot tub when it is full.
Let’s say we have a relatively small hot tub that weighs around 350 pounds, which has a water capacity of about 250 gallons. If we want to find the filled weight, all we have to do is add the empty weight to the weight of the water that it can hold inside.
Since we know that a gallon of water weighs about 8.34 pounds, we can calculate the water weight at around 2,085 pounds. Add that 2,058 pounds to your 350-pound empty hot tub weight to get a combined weight of 2,435 pounds.
Of course, don’t forget that your hot tub won’t just be sitting around empty. You will likely have some people in it too!
For average sake, let’s throw in two people at 150 pounds each. Add the tub at 350 pounds, the water weight at 2,085 pounds, and the two people at 150 pounds each (300 pounds), and we get a complete weight of 2,735 pounds.
Now, remember, this tub is fairly small. If we were to calculate the total weight of a larger hot tub with both the water and the people, we could easily end up with a combined total weight of around 6,000 pounds or more!
Where To Install A Hot Tub?
There are many places you may want to install your hot tub, including the backyard, the patio, or maybe even indoors! Who doesn't want a nice hot tub deck? However, it is important that you take caution, as irresponsible hot tub placement could lead to irreparable damage.
Many homes have a safety factor of 40 PSF (pounds per square foot). Even smaller hot tubs hover around 50-60 PSF. This is without water or people too! This means that even without being inside it, you risk damaging the structural integrity of your home if you misplace your hot tub.
In some cases, you may even risk breaking a few laws.
No matter how large of a hot tub you decide to buy, we recommend taking extra care in placing and installing it.
Yes, Hot Tubs Weigh A Lot
Hot tubs are incredibly heavy and that is no secret. Of course, if you want to cut down on the overall weight of your hot tub for whatever reason, you may want to consider getting an inflatable hot tub instead. They are much more portable compared to traditional hot tubs and have much lower average weight specs.
Whichever hot tub you ultimately decide on, be sure to calculate the overall weight before you buy it in preparation for installation, and so that you can protect your home and landscape.
