Best Overall

The Cover Guy Deluxe Hot Tub Cover

4.8

View On Amazon View On Thecoverguy.com

Order a replacement hot tub cover from The Cover Guy, and you benefit from the premium materials, custom fit, and functionality. The brand's Deluxe Hot Tub Cover is a popular option for hot tub use in milder climates. This cover features a 2-inch slope from the center to the edge to prevent standing water, and the product is rated for 150 to 200 pounds of weight per linear square foot. 

Features that make the Deluxe cover stand out from the crowd include a high-grade marine vinyl designed to stand up to sun and moisture exposure, extending the life of your hot tub cover. Inside, the cover is constructed with 1.5-pound closed-cell foam and energy-reflective materials. The result is a transfer of heat energy back to your hot tub rather than the atmosphere. For the Deluxe model, the insulation factor, known as an R-value, is 17. 

You can customize the shape and dimensions of this cover to fit your specific hot tub model and choose from 12 vinyl color options. Hot tub owners in cold climates can also take advantage of this cover option by upgrading to 2-pound foam for better insulation against cold temperatures. This cover also has additional upgrade options, such as selecting a weather-shield fabric cover, adding additional handles, or adding a fully insulated hinge for even more energy savings. However, all of the customization options do come at a hefty price.

While this pick is certainly a splurge, we think its thoughtful design and 7-year warranty make it a reliable choice.

Best for Winter

The Cover Guy Extreme Hot Tub Cover

View On Thecoverguy.com

Extreme cold can cause heat loss and turn your hot tub into a lukewarm tub—which is less than ideal when you're trying to thaw after a day on the slopes or on the rink. Avoid this problem and increase energy efficiency by choosing a hot tub cover designed specifically for colder climates. We recommend The Cover Guy's Extreme Hot Tub Cover.

This cover design is a level up from our best overall pick, the brand's Deluxe Hot Tub Cover, and it has even more energy-efficient features that make it ideal for the coldest climates. It does cost more, however, which is why we still call out the Deluxe as our best overall pick.

The Extreme cover is insulated with 1.5-pound closed-cell foam, which means it’s better equipped to trap heat inside your hot tub rather than letting it evaporate into the chilly outside air. Like other covers available from The Cover Guy, the foam is coated and wrapped to prevent it from absorbing moisture due to steam. 

In addition to cold temperatures, the Extreme model has a thicker cover to withstand higher snow loads: 200 to 300 pounds of snow and ice per linear foot. A seam stop running the full length of the hinge is an available upgrade to further insulate this hot tub cover and prevent warm air from escaping. Plus, the center seam is reinforced with aluminum for added strength against heavy snow and ice loads.

As with the other brand's available models, the Extreme cover has four lockable child safety straps that hold it secure against your tub. This also promotes better heat retention and prevents movement during heavy winds.

This hot tub cover is expensive, but we consider the upfront cost worthwhile considering its energy-efficient design and 7-year warranty.

Best Square Soft Cover

ULTCOVER Waterproof 600D Polyester Square Hot Tub Cover

View On Amazon

If you're hoping to fully winterize your hot tub for an extended period, the ULTCOVER Waterproof Square Hot Tub Cover is a great addition to your traditional hard cover setup. While this soft cover is not an alternative to an insulated hard cover, especially if you do not use your hot tub frequently, it's a great option to add an additional layer of protection that extends the life of your standard vinyl insulated cover. You could even throw this cover on the tub between uses if you need to run indoors to make lunch or use the restroom.

This polyester canvas cover features double-stitched seams and a water-repellent coating. The interior lining has a waterproof taped seam that helps keep heat inside your tub. An adjustable strap makes it easy to change this cover's skirt depth, while the elastic hem cord ensures that the cover stays in place once fitted properly. This cover also has air vents, which help prevent condensation buildup under the cover.

Best Round Soft Cover

Coverstore Custom Size Round Hot Tub Cover

Similar to our recommendation for the best square soft cover, this option from the Coverstore is for round-design hot tubs. It features a drawstring hem, air vents, and a water-resistant coating. We love the versatility of the Custom Size Round Hot Tub Cover because you can ensure that the cover size is perfect for your round hot tub and determine which type of fabric is best for your needs.

The four different material options—classic, elite, ultima, and prestige—offer varying levels of water, UV, wind, and fade resistance that is backed by respective warranties. While the different materials come at an additional cost, we appreciate this cover's affordable price point compared with other custom covers on the market.

As with other covers, this cover is also double-stitched around seams to ensure durability and prevent tears.

While this soft cover is not to be used in lieu of a hard insulated cover, it's a great way to extend the life of your vinyl hard insulated cover and ensure maximum weatherproofing during off-seasons.

Best Spa Blanket

Spa Depot Thermo-Float Spa Blanket

View On Amazon View On Walmart

Spa blankets, as they’re sometimes referred to, reduce heat loss, keeping your hot tub warmer and ready to go with less energy usage. They also help prevent water absorption in your hard insulated cover, which can lengthen your cover's lifespan. This option from Spa Depot's Thermo-Float brand is 16 mil thick, making it durable and energy efficient. According to the manufacturer, it can prevent up to 95 percent of evaporative heat loss when properly fitted and used. 

To use this product, you place the plastic bubbles facedown—they absorb solar energy and transfer it into your hot tub water. While this blanket is meant to be used without the cover, hence the solar component, it can also be used when your hot tub is covered between uses to maximize energy efficiency.

This blanket measures 8 x 8 feet, but you can trim it to fit your hot tub. Be sure you include an overhang of about 2 inches to ensure that the surface stays covered if the blanket shifts.
