Review: Great Cover - Love this cover, goes right over the spa top and protects it from sunlight, and all the other stuff out there. My top is going to last much longer. Review: Good Quality and durable - I installed this cover on my hot tub as soon as I received it. We live in an exceedingly high-wind area, and the cover stayed put. It is as described. Arrived as expected. The price was reasonable. It looks good on the hot tub and holds up well. The drawstrings on all four corners are a nice addition to help keep it in place. I am also able to take the main spa cover off without removing this one. I purchased this cover in August 2018 and was very happy with it. It is now December 19, 2019 and the cover failed miserably. I was adjusting the cover and not pulling very hard to move it when it tore. I'm not happy with the length of time it lasted, but I purchased another one. It served the purpose of protecting my hot tub, which was why I purchased it. It did that very well and lasted longer, according to the new owners of the residence. The above review was from a few years ago. Since then, I have moved from Nevada to Southwestern Utah. The weather is harsher here. Triple digits, high winds, blowing red dirt, and an area formerly known as the downwinder area, which is a result of the U.S. testing all those atomic bombs in Nevada. Anyway, in my previous review, I expected the cover to last much longer than it did. It did do the job but, for some reason, gave out in under two years, causing me to purchase a second cover. I just replaced the first cover that I purchased for my hot tub in Utah, which I purchased in early 2020. Now, three years later, more or less I am replacing that cover. It started failing at the bend in the main cover. I have to say that the cover has performed quite well. Obviously, since I have stayed with this company and its product. For whatever reason, that cover I purchased in Nevada in 2018 gave out early. The cover I purchased in Utah in 2020 has hung in there even with the harsher weather. I don't know why, I don't care as long as it lasts, and it did. So I just put the latest cover on today, 6-28-2024. We,ll see out this one goes. Hopefully another three years. The price is fair for the product and it is as described. I will continue to purchase this product regardless of its longevity. I do highly recommend this cover. It comes in many sizes and looks great. ## Features - General to fit hot tub size up to 90”(L)x 90”(W).

Can this cover stay on permanently without being removed?** A: Absolutely. That’s exactly what it’s designed for. It’s highly breathable to allow air circulation when left on long-term, preventing heat and moisture buildup. Just inspect it after extreme weather. It’s hassle-free, all-year protection. **Q: Are there different color options for the cover? Does color affect protection?** A: We mainly offer dark-colored covers, which provide better UV protection, stain resistance, and long-lasting good looks. Protection performance is not affected by color—all colors use the same multi-layer protective construction. **Q: What if the size doesn’t fit or there’s a quality issue?** A: We recommend sizing up rather than down. A slightly larger cover is easier to secure and offers better overall protection. If you have any material or quality issues, we’ll assist you promptly. **Q: How do I clean a dirty cover? Is machine washable?** A: For daily cleaning, wipe or rinse with water. For tough stains, gently scrub with mild detergent and air dry completely before storage.Machine washing is not recommended, as it may damage the waterproof coating. No tumble dry or bleach. **Q: What are our advantages compared to other brands?** A: Our cover provides complete protection with waterproof, fade-resistant, and windproof performance. It features high-density fabric with double-stitched seams and rust-resistant hardware. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Cover *by R***N on April 17, 2026* Love this cover, goes right over the spa top and protects it from sunlight, and all the other stuff out there.
