Protect Your Hot Tub with These Covers

A hot tub cover is an indispensable piece of equipment for anyone who owns a hot tub, indoor or outdoor. A cover keeps the heat trapped inside the tub itself to keep the water warm. This means it takes less time for the hot tub to heat up the next time you turn it on, which in turn saves electricity and therefore saves you money. Depending on how often you use your hot tub, a cover for it can cut your yearly electricity bill nearly in half. As a bonus, a cover will prevent the water in your hot tub from evaporating. If your hot tub is outdoors, it also keeps it cleaner as it keeps bugs, leaves, and other debris from getting into the tub or causing clogging, which can lead to further internal damage. It offers protection from snow, rain, wind, and sun as well. This will make sure your hot tub lasts and functions longer, preventing fading, cracking, or internal damage. For all these reasons, it’s clear that a hot tub cover is more or less a necessity for hot tub owners.

What to Consider in a Hot Tub Cover

Look at these features when shopping for a hot tub cover:

  • Size: A hot tub cover won’t do you any good if it doesn’t fit your hot tub properly. If it’s too small, it won’t offer full protection; if it’s too big, it risks getting easily blown off or dislodged. It’s a good idea to measure your hot tub before purchasing a cover, especially if you’re unsure of its exact size. Don’t forget to account for any add-ons like a waterfall or speakers.
  • Shape: Most hot tubs are square or rectangular in shape, so most hot tub covers will be, too. However, you may have a hot tub that is rotund, elliptical, octagonal, or has cut-off corners. While hot tub covers in these shapes are rarer than square-shaped ones, they do exist, so don’t feel like you have to settle for a hot tub cover with a shape that doesn’t match your hot tub.
  • Material: Most hot tub covers will be made of some type of vinyl. If possible, you’ll want to go for a higher-quality vinyl that is resistant to UV rays and humidity and is waterproof. A cover that’s been treated or coated with mildew inhibitors is a great option for resisting moisture and preventing the growth of fungi and mold. You’ll also want as thick a cover as possible; 3 to 6 inches thick and a 1-to-2-pound density is considered a good size. These provide better insulation against cold and precipitation and are sturdy against strong winds. If you live in an area with lots of snow, the thicker cover, the better. If you have small children or pets, you might want to spring for an aluminum cover for extra protection and strength. If you can, look for a hot tub cover that is reinforced with steel or aluminum reinforcer rods for extra sturdiness and easy alignment.
