The smart way to cover your built-in spa

In-ground spas need high strength to protect against people and pets putting their weight on the cover.  And you need light weight because cover lifters seldom work with in-ground spas. DuraCore has you covered, with a high strength walk-on cover that starts light and is guaranteed to stay light.


Modern materials and design

On the inside, most spa covers are simply a board of styrofoam.  Not the best material for an in ground spa where someone might walk or fall on a cover.  Our DuraCore spa covers have a high-strength internal construction that handles 500 lbs of weight, a tough plastic shell that doesn't break, and the highest R-value of any cover that's only an average 3 inches thick. 

Yes, you can try this at home...


Sometimes built-in spa covers need to handle heavy loads like dogs, kids or the occasional person.  Standard spa covers can fail in a moment under such loads, but DuraCore can handle several hundred pounds of weight with no problem.

Maintenance-free fabric covering

Would you rather not have to apply UV protectant to your cover to make it last for more than a few years?  Then you came to the right place.  Every Modern spa cover comes with the most advanced marine fabric covering available. Made from solution-dyed polyester fibers, it has a lifetime warranty against cracking.  Plus, the UV protection is built in to the fibers, so there’s no need for UV treatment.

The reviews are in. Our customers love our covers!

Starts out light and stays that way

Who wants to drag a hundred pound spa cover around just to take a dip?  Ordinary spa covers take on water quickly, getting heavy, then warping, causing loss of insulation value

Modern spa covers have multiple layers of moisture protection, including an industrial strength foil vapor barrier, and do not absorb water, making cover removal and replacement a snap.

A cover that makes you money ...

If you own a spa, you're paying regularly for heating energy and replacement covers.  A Modern Spa Cover usually saves you enough money on those to pay for the cover itself.  The energy savings can range from $1000 to over $3000, depending on your spa and where you live.  Tell us a little about your spa, and we'll send you a free savings estimate.  Just follow the link below:

Best insulation in a thin cover

The insulating value of standard foam spa covers can drop by as much as half after a few years, and you have the winter power bills to prove it.  And that warping allows hot steam to escape when the wind blows. DuraCore spa covers stay flat to seal the heat in and have a patent-pending high-tech insulating pack which doubles the insulating value of standard spa covers, keeping your spa water hot with less heater use.

Even stands up to hail  

Even a moderate hailstorm with marble-sized hail can destroy a vinyl and foam spa cover in a matter of minutes.  All Aztech spa covers are tested to withstand hail up to one inch diameter, or quarter-sized hail.  


The greenest cover you'll ever buy 

Standard vinyl and foam spa covers waste energy, and end up in landfills in just a few years.  Modern covers last far longer, are 90% recyclable, and save literally tons of carbon over their lifetime.  

Plus we offers the only solar heating spa cover on the market, our SunCatcher spa cover, which offsets up to 80% of electric heating, saving up to 8 tons of greenhouse gas emissions over its life.

SunCatcher's solar heating technology was awarded

First Place for Best Green Product at the 2017 International Pool and Spa Expo.  

Automatic snowmelt 

With our SunCatcher option you'll also get our exclusive automatic snowmelt feature uses your spa’s heat when needed to melt snow off your cover so you don’t have to.  Automatically detects and melts snow preventing deep buildup.
