It fits well and looks great. It was easy to put on by myself. It feels like very high quality, I think it will last a long time. Very happy with my purchase. 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 85”(L)x 85”(W). NOTE: This cover can not be used by itself without an insulated hard cover under it. - Made of 600D polyester canvas complex with waterproof backing. Tough enough to keep rain, hail, snow, dust, leaves and bird droppings away. - Well-made structured air vents at two sides keep ventilation, prevent the cover from being blown away, also keep your furniture dry and in good condition. - Heavy duty elastic cords allows adjustment for a tight and easier fit, especially during high winds and severe weather. - Full coverage design avoids the furniture exposure in the sun makes your hot tub always look like new. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089ZWQTNP | | Best Sellers Rank | #3,508 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2 in Pool Safety Covers | | Brand | ULTCOVER | | Closure Type | Hook & Loop | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (7,885) | | Installation Type | Self-installation | | Item Weight | 10.28 pounds | | Item model number | ORTCI | | Manufacturer | ULTCOVER | | Material | Polyester | | Model Name | 8AFCAB6E4-93157dacd9 | | Pattern | Solid | | Product Care Instructions | Clean with a damp cloth, avoid using abrasive materials, and store in a dry place when not in use. | | Product Dimensions | 85"L x 85"W | | Shape | Square | | Size | 85"(L)x85"(W)x20"(H) | | Special Feature | Waterproof | | Style | Heavy Duty | | UPC | 619317417281 | ## Product Details - **Brand:** ULTCOVER - **Color:** Black - **Material:** Polyester - **Product Dimensions:** 85"L x 85"W - **Size:** 85"(L)x85"(W)x20"(H) ## Images ![Waterproof 600D Polyester Square Hot Tub Cover Outdoor SPA Covers 85 x 85 inch, Black - Image 1](https://m.media-amazon.com/images/I/51-ZuDzhv-L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: I have a 2014 hot spring jetsetter and the measurments are 84" x 65 ". do you make this size?** A: Sorry, There are only two size available, 85x85 inch & 95x95 inch. **Q: Do they come in other sizes?** A: It will come in other sizes next year. **Q: Where is my cover it was supposed to be delivered on April 10 I’m getting no delivery time or date just that it’s on it way what’s up with this** A: Oh sorry, I was using it at my girlfriends house.

The fabric, fit, clips and barrel locks really allow you to tighten the cover close as possible to the spa walls. Our spa is 84”x84” with a cover lifter. I ordered the 85”x85” and it fits perfectly. One side of our spa abuts the deck and not enough space to fit the cover down between the spa wall and the deck. We folded the fabric up and under and clipped and tightened the barrel locks. Great product. Very pleased with the purchase. Also, color of the fabric is MUCH nicer than what you see online. A touch darker and richer looking. One suggestion I have for the manufacturer, consider making a cover for our situation where the spa is built into the deck. Make one side shorter. Just a thought. ## Frequently Bought Together - ULTCOVER Waterproof 600D Polyester Square Hot Tub Cover Outdoor SPA Covers 85 x 85 inch, Black - EASYTEST 7-Way Pool Test Strips, 150 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine - Hot Tub Bubble Blanket,16-mil 7x7 Foot Square Spa Cover Hot Tub Solar Cover, Heavy-Duty Heat Retaining Thermal Blanket. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/231437976-waterproof-600d-polyester-square-hot-tub-cover-outdoor-spa-covers](https://www.desertcart.vn/products/231437976-waterproof-600d-polyester-square-hot-tub-cover-outdoor-spa-covers) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
