The Biggest Drawback of Using A Hot Tub Cover

The Biggest Drawback of Using A Hot Tub Cover

Red CrossThe primary downside often revolves around the weight factor, making it somewhat cumbersome to lift. This can impact the overall convenience of using a hot tub cover.

To enhance ease of handling, one might explore options like cover lifters or materials that are lighter in weight.

What is a Hot Tub Cover?

A hot tub cover is simply a cover that keeps your hot tub protected. If it is the type of cover that has air pockets then it will capture energy from the sun and work just like a greenhouse.

They are sometimes called “tub covers” or “solar blankets”. A solar cover is environmentally friendly and a sustainable way to maintain your hot tub.

The Biggest Drawback of Using A Hot Tub Cover This is because it works off renewable solar energy, therefore reducing your need to use electricity.

The most popular solar hot tub covers look just like a plastic bubble wrap but don’t judge it by its basic looks.

The cover transfers heat to the water underneath during the day when the sun is out. And then it helps to keep the water warm at night.

In fact, some covers are able to increase the temperature of water by as much as 15 degrees Fahrenheit. This will help reduce the need to heat your tub before you get in.

Why Does My Hot Tub Need a Cover?

There are more reasons to get a hot tub spa cover than you might think. Here are some of the reasons why many hot tub owners find them invaluable:

  • Hot tub covers stop things from falling into your tub and potentially damaging it. This is especially necessary if your tub is located outside and exposed to the elements.Hot Tub Cover Opening
  • It also stops large debris, such as twigs and leaves from ending up in the filter, pipes, nozzles or pumps.
  • Using solar panel covers means that you can potentially run the entire system from this power source.
  • Even if you can only use the solar cover to power your hot tub some of the time, it will still lead to a reduction in electricity bills.
  • Hot tub covers are good for homes with children or pets. However, if this is your main reason for getting a hot tub cover then you should opt instead for traditional spa covers that are very sturdy.

Solar Hot Tub Cover Basics

Here are some basic terms associated with hot tubs and hot tub covers that will help you with your next purchase.


Micron is how the thickness of the cover is measured. A “micron” essentially means a very small unit of millimeters. 200 micron is the thinnest, lightest hot tub cover while 900 is the thickest and heaviest.

The bubble wrap is not there to make it look nice.

It is what allows your solar cover to retain heat – just remember to make sure the bubbles always face down.


Choosing the color of your solar cover should not be an aesthetic choice. Different colors have different functions.

Silver/Gold/Blue/Black and other dark colors will help prevent the growth of algae. If you want lots of heat then consider getting silver or gold as they can better reflect the sun’s rays deeper into the water.

Opaque/clear/transparent is ideal for hot climates. This is because a clear cover will be better able to absorb and let in infrared or UVA light which will penetrate into the water thereby keeping it warm.

Electronic Solar Powered Spa Covers

Jacuzzi Spa PlugThe electronic versions of solar covers do everything the basic bubble wrap covers do but with 100% more intensity and effectiveness.

This is why I will only be reviewing electronic solar hot tub covers from this point onwards.

Which Is The Best Solar Hot Tub Cover?

Solar hot tub covers do more than just keep your hot tub covered so that it doesn’t get damaged by the elements. They can function as a power source too.

Mr Water Geek ThinkingCovers are completely necessary if your hot tub is outside.

Otherwise, twigs, stones, debris, leaves, insects and even some animals will find their way into your hot tub.

And there is no telling how much damage these things can do once they enter your tub system.

mrwatergeek winner badgeGetting a tub cover is also a good idea if you have young children or pets in the home.

But why settle for a standard, boring cover when you can have a modern hot tub cover that can also heat your tub water.

Hot Tub CoverIf you’re going to be making this type of investment, it’s worth considering the electronic ones instead of the basic bubble wrap versions.

They are more effective and pay for themselves in the long rung with all the money you save on electricity bills.

My favorite solar tub cover is the Prestige range. It is a great product that works very well and offers great value for money.
