Every spa is different in its shape and size, and when you’re choosing one for your home, this is a very important thing to keep in mind. How much water does each hot tub size hold and why is this so crucial to know? We’ll be taking a deeper look at how much water is in a 6-person hot tub below.
A 6-Person Hot Tub’s Water Capacity
Generally, a hot tub that can hold six people has about 320 to 475 gallons of water in it. This might seem like quite the range, but consider that even hot tubs that are supposed to be the same size are designed differently. Each hot tub is unique and factors like the size of its seats or the shape of the spa can change the volume of water. When it comes to electrical use, a hot tub’s water only accounts for about 1% of your household’s water usage. When broken down, this is less than 3 gallons a day. However, how do you determine how much water your specific make or model can hold? We’ll help you figure that out now.
When looking at different 6-person hot tubs before choosing the right one, you might notice that they come in all shapes and sizes. Although the approximate amount of water should be similar, there are a few ways to find the exact number you’re looking for. You can look at things like the height of the hot tub or whether it’s square, round or more rectangular shaped. You can even check to see what the seats look like, as larger seats will take up more volume, which means less room for water. This isn’t to say having less room for water is a bad thing, just one of the ways to find your answer of how many gallons it can hold.
When filling your hot tub for the first time, it’s important to only fill it to the safe line indicated on your spa. This ensures that the water levels will not rise to a point where they might overflow if people enter your hot tub. It also ensures that it’s high enough that the pump, jets and filtration systems can function as they need to. This is important to note if you’re unsure how many gallons it takes to fill your specific hot tub because you will need to ensure you don’t leave it unattended for too long.
But knowing how much water your hot tub holds precisely is important for costs associated with chemicals, electricity, heating and more moving forward. Here’s how you can find the exact number.
Figuring Out How Many Gallons Are In Your 6-Person Hot Tub
If you’re trying to figure out how much water your hot tub model holds, your owner’s manual could provide this information. If not, you can also call the manufacturer or salesperson you received it from, and they can assist you with this. It’s important to know how many gallons your hot tub can hold because you want to ensure you’re putting the right amount of chemicals in it. In addition, this will allow you to maintain a healthy reading of 7.2 – 7.8 pH.
There is also a fun little experiment you can conduct, and all that’s needed is a stopwatch, a hose and an empty gallon jug. You’ll start by filling your hot tub with water from your hose and timing how long it takes to fill. Once you have this number, you’ll need to convert it into seconds. Once your hot tub has been filled with water, you can then fill your one-gallon jug and record how long that takes too. From here, you will simply divide the time it took to fill your hot tub by the time it took to fill the gallon jug. This will give you the answer to how many gallons of water your hot tub can hold.
Knowing this number helps with many things, both short-term and long-term, and it’s beneficial to be aware of how much water content is in your spa. To learn about choosing the best hot tub for you and your home, download our free hot tub buyer’s guide.
