Hot Tub Works Offers the Best Warranty

The spa cover warranty from provides protection that is second-to-none. At 5 years, non-prorated, “bumper-to-bumper” coverage, our warranty includes full protection for moisture in the insulation core which is the single biggest cause of spa cover failure. Our advanced sealing technology is so reliable that our warranty covers the insulation and includes the cost of replacement freight from the manufacturer for the first year.

Our Moisture Lock Heat Seal is Exclusive

Hot Tub Works uses an Exclusive Moisture Lock seal on all of its spa covers and hot tub covers. Moisture absorption in the insulating core is the number one cause of spa cover failure. When a spa cover becomes so heavy it’s difficult to lift, it’s because of moisture intrusion. Moisture destroys the integrity and insulating value of the spa cover, and our Exclusive Moisture Lock seal is the best defense against this issue and the reason we can offer the industry’s best warranty.
