How long should Hot Tub last? Many potential hot tub owners worry about the lifespan of their hot tub. This article will give you tips on how to improve the lifespan of hot tubs.

How long does a hot tub last on average?


Two major factors affect the lifespan of a spa.

  • Quality. A hot tub made from higher-quality components will, on average, last longer than one built with lower-quality components.
  • Maintenance. A hot tub that is well-maintained will last longer than one which has not been cared for regularly.

Pumps & Heaters


It is difficult to estimate the average life expectancy of a hot-tub pump or heater. The water balance of your hot tub is a major factor. In well-maintained water, hot tub heaters and pumps can last for 7-10 years. However, if the water is not balanced, it can drastically reduce their lifespan as components start to break down.

This is the seal used to protect the motor in hot tub pumps from water. When the seal fails (normally due to acidic water levels or high sanitizer concentrations), water will seep into the motor and cause it to rust. This can occur in extreme cases after only a few years of being exposed to consistently bad water.

Water balance is also a very important factor for hot tub heaters. Acidic water (low pH), can cause the heater elements to corrode and break down, causing water balance problems. Water that is too basic (high pH or alkalinity), or hard (high Calcium Hardness), can cause the heater to rust and build up scale. This will reduce its effectiveness. When hot tub heaters are constantly exposed to unbalance, they can fail in a few years.



Hot tub covers play a vital role in the insulation of your hot tub. The covers have a life expectancy that is only 3-5 years. The life of your cover can be extended by regular cleaning and UV protection, but you will eventually need to replace it.

If your cover is waterlogged, heavy or begins to cup it will no longer be able to do its job as an insulator and needs replacing. For more information on how to extend the life span of your cover, consult our guide.

Shell & Cabinet


Hot tubs can last up to 30 years without any maintenance. Clean the cabinet periodically using a hose. Make sure to repair any minor leaks immediately.



Two factors can affect the lifespan of a jet hot tub:

  • Type of jet. Jets without moving parts last almost always longer than jets with moving parts.
  • The balance of water . Acidic water may wear away the plastic backings that hold the jets in position. Water with a high pH can lead to scale formation, which increases friction and wears out moving parts.

If you maintain your water, your jets should last between 7-10 years. Unbalanced, the moving parts of a jet could break down within 3 years. Jets are inexpensive and easy to replace without calling in an expert.



In a hot tub that is well-maintained, hot tub pillows can last up to 3-5 years. However, they may last only one year in an unbalanced hot tub. Pillows are easy to replace and relatively cheap, just like hot tub jets.

How to Extend the Lifespan of Your Hot Tub


To extend the life of your hot-tub, you should first purchase a high-quality hot tub and then make sure that you maintain it. If you don’t maintain your hot tub properly, even a high-quality hot tub can have its life span drastically reduced.

You should test your water regularly and add chemicals as necessary to ensure the longevity of your hot-tub. Home tests are recommended to be performed around 2-3 times a week, and professional tests at your local retailer should be conducted once a month.

Professional tests are more accurate and test for a wider range of things than the tests you can do at home. You can maintain a more balanced water system and fix issues like cloudy or foamy waters.

You should test your hot tub regularly and change the water every 3-4 months. At the same time, you should clean the plumbing system and shell. It will be easier to balance the water over time and reduce the likelihood of cloudy or foamy waters.

When should you replace your hot tub?


How to know when it’s time to replace or repair a hot-tub is one of the most frequently asked questions by hot-tub owners. This really depends on two factors.

  • The cost of repair.
  • Age of the hot tub

It is worth fixing your hot-tub if the cost is low, no matter how old it is. As the cost of repair increases, it is important to take into account the age and value of the hot tub in relation to the repair.

If you have to spend $1,000 on a hot-tub that’s 8 years old, but is still likely worth a few thousands of dollars, it may be worth the repair. If, however, your hot tub is 15 years old but only worth a couple hundred dollars then it’s not worth spending $1,000 on repairs.

Wrapping up


No hot tub can last forever, no matter how well it’s made. You’ll want to buy a hot tub with high-quality parts if you want it to last. should be used to test and balance the water.
