Hot tub covers are essential because they keep your spa clean and safe. They prevent impurities from getting into the water, they stop pets or small children from drowning, and they help retain heat so you can make use of your spa anytime and minimize heating costs. In addition, they shield the spa from the sun that can destroy your investment.

But even if you care for your spa, you have to change its cover later. This can happen for numerous reasons. Through the years, your spa cover may become heavy and waterlogged, maybe even moldy. If rain accumulates above the cover, it is absorbed by the foam which sags. This affects the spa covers insulating effect, creating bigger heating bills.

As things get worse, the stretched vinyl cover may break or end up so heavy from collecting water that its hard to move. Until you get a new spa cover, you can stop water-logging by unzipping the cover every two to three months and dry the foam.
