What factors influence the lifespan of a hot tub?

The question “How long does a hot tub last?” is related to:

1. Choice of material

An inner tub made of glass fibre reinforced plastic – as we use – is extremely strong, UV-resistant and resistant to scratches and dirt. In combination with thermo wood for the edging, you get a hot tub that will last for years and remain beautiful if properly maintained.

2. Use

How often and how intensively you use the hot tub plays a role. Intensive use is not a problem, as long as the maintenance is adjusted accordingly. Also see our tips on using the hot tub .

3. Maintenance

Good hot tub maintenance is essential. Think of cleaning the tub, the filter and treating the water. This prevents limescale, blockages and wear. It is also important to treat the thermo wood with Tar Oil once or twice a year. This protects the wood and preserves its beautiful colour.

4. Weather influences

Sun, frost, rain – your hot tub has to endure a lot. Use a good cover, and read our blog about winterizing your hot tub . This will protect your hot tub from the elements and prevent long-term damage.

How to extend the lifespan of your hot tub?

Good maintenance is the key to a long lifespan of your hot tub. With a few smart habits you can ensure that your hot tub will last up to 25 years. These are the most important points of attention:

Clean your hot tub regularly

• Weekly: Check water quality and add cleaning agents if necessary.

Treat the water correctly

Good water treatment prevents limescale, algae and wear. Use the right maintenance products, such as Aquaclean or chlorine products, and check the pH and chlorine values regularly. The ideal pH is between 7.2 and 7.6 .

Tip: With frequent use or warm weather, you should measure and adjust more often.

Maintain the stove

Drain the wood stove regularly and rinse it with water. Check that no dirt or deposits remain in the combustion chamber or flues. This will maintain the stove's efficiency and lifespan.

Protect your hot tub from the elements

Always use a good cover to keep dirt out. In the winter it is important to give the hot tub some extra attention. The tub can withstand frost well, but it is important not to let the pipes freeze. In this blog we will tell you how to make your hot tub winter-proof.

Perform major maintenance annually

Schedule a comprehensive maintenance check every year: check the tub, exterior, heater and pipes for wear, dirt or blockages.

When does a hot tub need to be replaced?

A quality hot tub from Welvaere will last, with proper maintenance, an average of 20 to 25 years. After that, it may happen that certain parts show some wear or that you notice that your hot tub is no longer working as efficiently as before. 

You may consider replacing your hot tub (or parts thereof) when:

• The tub is difficult to clean or is visibly worn
  
• The wooden edging loses its strength
  
• The stove heats less efficiently or maintenance becomes more intensive
  
• The filter installation needs to be replaced more often and is less powerful
  
• You notice that comfort or energy consumption no longer meets your needs

In many cases, replacing a part – such as a filter or cover – is enough to enjoy it for years to come. But if your hot tub has been around for quite a few years and you are ready for more comfort, better insulation or a more modern look, a new model may be worth considering.
