ULTCOVER Waterproof Square Hot Tub Cover vs Spa Cover Thermal Hot Tub Cover

The ULTCOVER Waterproof Square Hot Tub Cover was well-received by reviewers at The Spruce, a trustworthy source that performs unbiased hands-on testing. It did great in their "The 6 Best Hot Tub Covers of 2023, Tested and Reviewed" roundup - they named it their "Best Square Soft Cover", which, by itself, suggests that it's a noteworthy product.

Taking a look at the Spa Cover Thermal Hot Tub Cover, we found that it hasn't managed to perform well enough to earn a spot in any Hot Tub Cover roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head ULTCOVER Waterproof Square Hot Tub Cover vs. Spa Cover Thermal Hot Tub Cover comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
