How Many Gallons In A Hot Tub
Whether you're concerned about a patio or deck supporting the weight of a standard hot tub, or have water usage in mind, determining your hot tub's gallon capacity is crucial.
Several factors go into calculating out how many gallons of water are in your hot tub, including the size, shape, and capacity.
We're going to break it all down and help you determine exactly how much water your hot tub holds.
Let's get started!
Calculate How Many Gallons of Water Your Hot Tub Holds Based On Size
On average, the smallest hot tubs that you'll find from manufacturers are two-person hot tubs. Typically, two-person hot tubs will hold anywhere from 150-220 gallons of water. A standard deck should not have any problem supporting the weight of a two-person hot tub.
For those who want to take it up and get a three-person hot tub, you should expect it to hold anywhere from 200-300 gallons of water. Similar to a two-person hot tub, a three-person hot tub should be fine on a standard deck.
If you're looking at a 4-6-person hot tub, you may need to start considering some reinforcements. An average 6-person hot tub typically holds anywhere from 320-475 gallons of water. A 6-person hot tub may present challenges for those who place their hot tub on the deck depending on the number of people who are in it at one time.
How To Figure Out The Precise Number of Gallons Your Hot Tub Can Hold
There are a few ways to calculate how many gallons of water your hot tub's interior can handle.
One of the easiest ways to figure out how many gallons you'll need for your hot tub is to look at the manual.
If you misplaced the manual a while back, you can always run a quick Google search to see if you can find the amount online.

If you can't find that information, you can also calculate the number of gallons of water your hot tub can hold manually.
To get started, you'll first need to grab a tape measure.
Filling Method
Lastly, you can use the timed fill method. You can figure out the capacity of your hot tub and how many gallons it holds by filling your hot tub with a hose. Make sure you time the filling process so you know how long it took to fill.
