What Is the Average Lifespan Of a Hot Tub and How Can You Increase It?

How long does a hot tub last? This is a question that many people have, and it’s a valid one. A hot tub can be a great investment for your home, but it’s important to know what you can do to ensure it lasts as long as possible. Below, we’ll talk about a hot tub’s average lifespan and some tips to help extend its life. Here’s what you should know!

Do Hot Tubs Have a Long Lifespan?

The short answer is yes, hot tubs can last a long time. In fact, the average lifespan of a hot tub is about 15 – 20 years! Of course, this number can vary depending on several factors. First, the quality of the hot tub and the materials used to make it can impact how long it will last. It’s important to do your research on the manufacturer of the hot tub you want. Are they known for designing spas with durability and sustainability in mind? Do they continuously develop features that protect the different hot tub components? For instance, Hydropool is a leading brand with more than 50 years of experience. They have a wide range of spas, all of which feature superior components and design features that make for a long-lasting hot tub. To learn more about the different Hydropool spas available in your area, you can reach out to your local hot tub dealer.  

Another factor is the maintenance that goes into your hot tub. If you take good care of it, then your hot tub can last longer. Proper maintenance includes cleaning it regularly and ensuring all parts are working correctly. In addition, if you make sure to check for damages on a regular basis, then you can address them before they become serious issues.

How Long Do the Running Parts Last? 

Now that you know the overall lifespan of a hot tub, you might be wondering if the key components will also last that long. Let’s take a look at each one:

The Heaters and Pumps

These two components typically last for about 7 – 10 years before needing to be replaced. The biggest factor affecting these parts’ life is water chemistry. If you keep the pH levels between the ideal range of 7.2 to 7.6, the heater and pump will last longer. 

The Jets

The jets in a hot tub are also designed to last for around 7 – 10 years. To keep them working longer, you also need to keep an eye on the quality of the water. High acidity can wear out the plastic backing that holds the jets in place. On the other hand, if the water is too alkaline it can cause scale build-up. This can also damage the jets over time.

 The Shell

This component, which is part of the outside structure of your hot tub, can last for the full 15 – 20 years. In some hot tub models made with high-quality materials, the shells can even last between 20 to 30 years. Not much maintenance is required for this part of the hot tub, but it’s important to keep an eye out for any cracks or damages that could lead to leaks.

Tips to Make Your Hot Tub Last Longer

If you want to get the most out of your hot tub and make it last longer, here are some tips you can follow:

  1. Have a regular cleaning schedule for your hot tub. Scrubbing, vacuuming, and cleaning the filters will help prevent any build-up that could cause damage.
  2. Use testing strips or a kit to check if the pH levels are in the ideal range.
  3. Drain and refill your hot tub every 4- 6 months. Over time, the water can become stale and contain unwanted bacteria. Make sure to change the water regularly to keep your hot tub clean and safe.
  4. Protect your hot tub with a cover when it’s not in use. This will help prevent dirt and debris from getting into the water and damaging the running parts.

With these tips, you can play a large role in helping your hot tub remain in great condition for many years to create memories that will last a lifetime. Download our free buyer’s guide for more advice on choosing the perfect hot tub for your home.
