The ULTCOVER Waterproof 600D Polyester Square Hot Tub Cover is made for hot tubs that are up to 85 inches on each side and 20 inches tall. The manufacturer describes it as waterproof, using 600D polyester fabric with a backing to shield your hot tub from rain, snow, and dust. Just keep in mind, it's best used with an insulated hard cover underneath, as it's not a standalone solution.

From our research, it seems people have mixed feelings about its long-term durability. At first, many folks found it did a good job of staying in place and protecting their hot tubs. But, some encountered issues eventually. It seems fading in direct sunlight or wear and tear within 6 to 18 months is a common concern. Its lifespan varies; some have seen it last up to two years in tougher climates. For some, this is still more cost-effective than regularly replacing pricier insulated covers.

One particular issue noted by people in really sunny places like Arizona is the undercoating has allegedly melted after a few months, which isn't great. Also, the elastic cords might fray and tear at the exit points since there aren't any grommets there. While some appreciate the warranty, others feel it's not very helpful (only one replacement in a supposed three-year warranty).

In short, the ULTCOVER might be a decent option if you're looking for an affordable cover, but do consider these experiences, especially if you live where the sun is pretty relentless. It might be wise to look into some extra sun protection or treatments to stretch out its lifespan.

Before deciding, weigh these points and maybe think about using extra protective stuff alongside this cover.

So, about the ULTCOVER hot tub cover and whether it fades in sunlight—here's the scoop.

It's made from 600D polyester canvas with a waterproof backing, meaning it does a great job dealing with rain, snow, dust, and debris. But when it comes to sunlight, it's a bit of a different story.

From what we've found, this cover generally performs well across many weather conditions. However, if your hot tub is consistently under direct sunlight, you might notice some fading over time. This seems to be a pretty common observation, especially for those living in really sunny spots.

Even with this potential fading, the cover's still a solid choice for protecting your hot tub. It doesn't replace your main thermal insulation but works well as an added layer to guard against the elements.

Just keep the fading factor in mind if you're placing it in a super sunny area, and it'll still deliver as a reliable protective layer.

How long the ULTCOVER hot tub cover lasts really depends on where you live and the weather it's up against. The manufacturer mentions it's made from heavy-duty 600D polyester fabric with a waterproof backing, designed to keep out rain, snow, dust, and protect against UV rays.

In general, these features do help with durability, but harsh weather—especially really high temperatures—can still be tough on it.

From what we've found, people's experiences vary, particularly in really hot places. For example, in states like Arizona where temperatures can hit over 115°F, some have noted issues like the undercoating melting, which suggests it's not the best fit for super hot climates. The intense sun and heat in such areas seem to speed up wear and tear, causing problems like fading and tearing.

In milder climates, the cover seems to last well and does a good job against typical outdoor conditions. But if you're in a place that's constantly hot and sunny, you might find the cover doesn't last as long—usually about a year, based on feedback we've seen.

So, if you live in a location with persistent high temps and blazing sunlight, you might want to consider extra protective steps or looking into covers specifically designed for extreme weather. It could help your cover last longer and keep doing its job effectively.
