Do you love the soothing embrace of your jacuzzi but wonder how often should you change hot tub water to keep it clean and safe? You’re not alone! Many hot tub owners are unsure about the best practices for maintaining their spas.
But not for long, as this article will explain why and when you should change your water. So, let’s begin!
Why Is It Important to Change Hot Tub Water Regularly?
Regularly changing your spa water helps prevent the water from getting contaminated by stuff like oils and bacteria. This enables a safer and more enjoyable experience every time you soak.
So How Frequently Should You Change Your Hot Tub Water?
Adding chlorine to your H2O won’t make it free from bacteria forever. We recommend changing your water every three months with average use, but this can vary depending on how often you use it.

Factors that Determine How Frequently You Need To Change The Water
The main determinants of how often you should change your hot tub water include:
The Starting Water Quality: Make sure the water in your hot tub is clean and not cloudy.
The Chemicals Quality: Use test strips to ensure the water chemistry is balanced. If it’s off, you should change the water to remove chemicals before it becomes supersaturated.
Swim Spa Usage Frequency and Number of Users: Track the number of people using the hot tub.
The Effectiveness of Your Filtration and Purification Systems: Ensure the filtration system keeps the water clean.
How to Calculate a Hot Tub’s Water Changing Frequency?
Math does get used in real life! Even for your hot tub maintenance.
To calculate how often you need to change the spa water, you’ll need to know a few things like:
Volume & Bather Load
As I mentioned earlier, the number of people in your hot tub can primarily determine how often you should clean it. But the size of the hot tub and the amount of fresh water it can hold are equally important too.
Refer to the table below to gain a better understanding of this.
| Size | Number of People it can hold | Water Quantity |
| Small | 2-3 | 170 gallons (about 650 liters) |
| Medium | 4-5 | 330 gallons (about 1250 liters) |
| Large | 7-8 | 610 gallons (2300 liters) |
Applying the Formula
Now that you’re aware of those numbers, let’s start with the formula. Is your calculator ready? To apply this formula, divide the hot tub volume by 3, then divide that number by the bather load. Like this:
Spa volume ÷ 3 ÷ estimated average bather load = water change frequencyEg: 170 gallons ÷ 3 ÷ 2 bathers = change every 28 days with clean water |
Remember, this is simply a guideline; this formula isn’t the only answer to the question of how often to change hot tub water.
Conclusion
So, how often should you change your hot tub water? It depends on a few things, like the water you start with and how you take care of it.
Regular maintenance, such as testing the water chemistry, using sanitizer, and keeping the filters clean, can help keep your hot tub water clean and clear. Happy Soaking!
