How DuraTherm Makes a Better Spa Cover

Duratherm spa cover manufacturing process

First, a CAD drawing is created from your measurements. Then the spa top skin in your color choice is precisely cut by computer-guided machines, while the inner core is crafted to matching dimensions. This assures a great fit for your beautiful new hot tub cover.

But a DuraTherm cover's good looks are more than skin deep. What you can’t see are the 30 points of internal reinforcement, extra work done to assure durability and strength. And our cores provide better thermal insulation and moisture resistance, for energy savings year after year.

Excellent cover

Lightweight, durable, easy to open. Love this cover.

4 years before falling apart

I’ve been very happy with the cover up until the four year mark, at which time the fabric started ripping and the seams falling apart. The tub is not sheltered at all, and I live in New England, so the cover did endure some abuse from the elements, but I expected that with a little duck tape I could squeeze at least five years out of it, but no way. The cover is falling apart in every way - the seams, the fabric, you name it. For $500 (2019 prices), I expected more life than I got.

Highest quality cover

I purchased this cover in 2020. I chose the highest quality material. This past summer, it started "taking on water". I knew it was going to need replaced soon, but I thought I might make it through the winter. Last week, I opened it and it tore the screws from the lift right out of the side of my hottub. So much for the lighter material. I feel like I should get more than 3.5 years out of a cover. I got 5 years out of the manufacturer's cover.

Horrible cover

Would not recommend Spa Depot. The cover seems cheaply made for $500, and have only had four months and the cover is leaking mildew water after every rain. Our old cover, though badly faded, was better made

I'm very sorry to hear about this. Our cover team will be contacting you shortly to get more information and get this taken care of.

Amazing cover!

This cover is a massive upgrade over what we had before. So light and well designed. We ordered the double seal on the inside because our last cover ended up weighing at least 50 pounds and I broke the lifter it got so heavy. The under spa lifter from Spa Depot works great as well.
