Spa Covers: Get the Most from Your Investment


spa cover


Spa covers are one of the most important investments you can make for your spa or hot tub. Not only will a cover keep your hot tub free of debris and ready to use, they also play an important role in conserving heat, water and chemicals. Quality hot tub covers can cost $294-$500, and sometimes more. But with proper care and regular maintenance, you’ll extend the life of your spa cover and get the most from your investment.


Choosing the Right Cover

It’s important to buy the right size. Improperly sized spa covers diminish your cover’s ability to conserve heat, water and chemicals, plus the foam panels are more susceptible to damage. A poorly fitted cover can also be an eyesore. With Hot Tub Works, you can easily search covers according to the make and model of your spa, or you can request a custom size and shape.

For this part of the equation, it’s important to consider where your spa is located. Do you live in a mild climate, or are snowy winters a trademark for the area? An indoor model or a spa in warmer climates can use thinner, lower density 1 lb. foam, whereas an outdoor spa in cooler climates will need thicker and heavier 1.5-2 lb. density foam.

Other Options
There are more options to increase the efficiency and longevity of your new Hot Tub Works spa cover. A continuous heat seal provides additional structural support and helps in reducing heat loss. To prevent moisture from penetrating the foam, a double vapor barrier around your core is the best policy. If you live in windy or stormy climates, prevent damage to your cover by upgrade the existing safety straps with heavy-duty ASTM approved wind straps.

Maintaining Your Cover

Let It Breathespa cover lifter
Even though the foam cores are sealed with a vapor barrier to lock out moisture, regular airing it out helps prevent the growth of mold and mildew on the rest of the cover. Simply open the cover and leave it off the spa for an hour twice a week or a few hours once a week. Using a spa cover lifter will make this job significantly easier, and a lifter will also prevent cover damage while it’s off the spa.

Strap it Down
When your spa or hot tub is not in use, it’s important to keep the cover strapped down or otherwise secured to prevent it from blowing open or falling into or off the spa. Securing your cover is also a safety measure to prevent accidents with children or pets.

Lighten the Load
On that same note, it’s important to keep heavy objects (including children and large pets) and excess snow accumulation off spa covers. Although covers are reinforced with sturdy metal braces, the added weight can damage the integrity of the foam and/or bend those braces, causing a progressive sagging effect.

Clean and Conditionspa cover cleaner and conditioner
Mother Nature is hard on vinyl covers. Freezing winters, sizzling summers, strong storms and the sun’s harsh UV rays all take their toll on a cover. To keep your cover looking better longer, it’s important to regularly clean and condition it. Avoid using harsh chemicals such as detergents, dish washing soap, alcohol-based products or products containing bleach, oil or silicone, as they can damage the vinyl. Only use specially formulated cover cleaners or cover wipes. Abrasive scrubbers will damage the finish, so use a small towel, soft sponge or soft-bristled brush instead.

Once your cover is clean, apply spa cover conditioner to keep the vinyl soft and pliable and resist damage from UV rays. Clean and condition your cover at least 3-4 times per year for best results. In between cleanings, it helps to keep it brushed off or wiped down to prevent accumulation of leaves, pollen, dust and dirt. In the event of mold or mildew growth, swab the area with diluted vinegar and allow the cover to dry out completely.

Other Tips
Check your cover regularly for damage or signs of wear. If the moisture seal around the foam core gets punctured or torn, patch the affected area immediately to prevent the foam from absorbing water. In addition, you can keep the foam cores from sagging by flipping them over once per year when the cover is completely dry. Another option to prolong the life of your cover is to purchase a cover cap for extra protection against UV rays, inclement weather, dirt and debris.
