After spending so much money to install a hot tub, you expect that it will last a long time. What's more, you expect that it will not cost you an arm and a leg to maintain and keep it hot. Among the things you can do to protect your beautiful tub and keep your maintenance cost low is to cover it. The best hot tub covers insulate your water from heat loss and protect it from chemical degradation, dirt, and debris.

If you got your hot tub from a high-end brand like Cal Spas, it likely came with a cover already.

Hot tub covers come in many shapes and forms, from simple canvas designs to unconventional caddy. We picked out these five hot tub models from dozens of listings because of their durability, heat sealing abilities, safety, and of course value for money.

What Is The Purpose Of A Hot Tub Cover?

If you have a hot tub, getting a replacement cover for it is non-negotiable unless you want your entire investment to go to waste. Some of the reasons you MUST buy the best hot tub cover you can afford include;

1. Prevent Evaporation

Water naturally evaporates whether it's hot or cold, and this happens more if the hot tub is exposed to sunlight. When you leave the hot tub open, you can expect to find your water level going down by the day, which means you have to constantly refill it, which costs money. As the water evaporates, so do the chemicals you put to keep the water clean and balanced. This means you have to add more chemicals even as you replenish the water.

2. Prevent Heat Loss

Did you know it takes 12 to 24 hours to heat some hot tubs? That is a lot of energy to use, so you have to find ways of keeping the water hot once you shut off the power. The best hot tub covers come with next-level insulation abilities to keep the water hot for hours. The cover also allows water to heat up quickly because the heat is not being released into the environment.

3. Cleanliness And Durability

Whether your spa is indoors or outdoors, there will always be dirt and debris ready to fall into the water. Besides making the water dirty, such debris can get into your filter or sump pump and destroy your hot tub's components. The best hot tub cover ensures this doesn't happen by protecting your tub from any dirt or debris.

4. Safety

The most important reason you need to cover up indoor and outdoor hot tubs is the safety. A hot tub cover protects your children and pets from falling inside the tub and drowning. The best hot tub covers come with a firm surface and heavy duty elastic cords or locks to ensure kids and pets can't fall into the tub.

How Do I Choose A Hot Tub Cover?

As you may have noted from the selection of energy efficient spa covers we have highlighted, the best hot tub covers are not cheap. You want to invest in a cover that's durable and will take you at least a decade before you think about replacing it. These hot tub cover features, along with how well you take care of the cover, will help you with that.

1. Foam

The best hot tub covers are constructed with high-density foam because it's effective at maintaining water temperature. The normal range is between one and two pounds, but the thicker the foam, the better its heat retention. Be sure to also check how the foam tapers towards the sides to aid in water run-off.

2. Vapour Barrier

A vapor barrier is a protective cover that encases the foam of your hot tub cover. It should be water-tight and water-resistant to prevent vapor and moisture from getting inside the foam. A poor quality vapor barrier will leave the cover vulnerable to mold and mildew, not to mention degradation.

3. Material

When choosing a hot tub cover, you want something that can withstand any weather. When it's hot, the material should not start melting and getting weak. This applies too when it's cold, and snow is falling. The best hot tub covers are made of high-quality vinyl, which is water and UV-resistant. For durability, check for the weight per square meter of the vinyl because this tells you how durable and strong the material is.

4. Extra Features

Some of these features aren't essentials, and they may drive up the price of the cover. However, they do add a level of safety and effectiveness if you can afford them. For example, the c-channel, a steel bar that runs along the perimeter rim of the cover to weigh down the cover against strong wind, is an important feature. It can also prevent kids and small animals from prying the cover off.

Another great feature is safety locks/buckles to ensure the cover is locked shut and kids can't be able to open it. Check also the R-value, which describes the heat retention of the cover. Last but not least, check whether you need a hot tub cover lift to make moving the cover much easier for you.

How Long Should Hot Tub Cover Last?

A good spa cover typically lasts between 5 to 7 years. Factors such as UV radiation, snow, falling debris, and other types of damage can affect the life-cycle of the hot tub cover. However, with some maintenance such as cleaning and applying protectant treatment, the hot tub cover will give you excellent service for a good number of years.


When sifting through the best hot tub covers, let price be the last thing you consider. Like most things, cheap will end up costing you more in the long run. For that perfectly snug fit, you can try any of our custom-made picks and choose everything for yourself.
