While we may wish that our purchases would last forever, all things wear over time, especially items exposed to the elements. Hot tub covers are one such item, and their maintenance is often overlooked and left unconsidered. In this article, we will show you how to recognize what a bad cover looks like, how to choose a new one, and how to keep that cover in excellent condition for years to come.
The last thing you want to see when you’re ready to unwind is cold water in your spa because your cover no longer holds in heat. fortunately, most worn-out covers show signs of deterioration long before they begin affecting your spa’s performance. Knowing what to look for can help you replace your cover before it costs you comfort, energy, and money.
Signs of a Faulty Hot Tub Cover
Cold Spa
Heavy or Sagging Cover
Tears, Rips, or Melting
Regardless of climate, a good spa cover should help your spa maintain its temperature between uses. In cold climates, having a functional cover becomes crucial for heat retention. If you routinely see your spa losing heat despite the cover being secured, then the cover is likely compromised.
A spa cover should feel relatively lightweight and keep its shape. If it has become noticeably heavier, sags in the middle, or collects standing water after it rains, the foam core has likely absorbed too much moisture. A waterlogged cover loses much of its insulating value and is usually a clear sign that it is time for a replacement.
Whether from storms, kids, or UV damage, physical wear will happen. Once the protective outer layer is torn or punctured, moisture can easily penetrate the cover’s insulating material, reducing the cover’s protective abilities.
