Completely different, inside and out

We've moved beyond foam and vinyl.  Our DuraCore covers have a completely different internal construction than ordinary covers.  A tough plastic shell that doesn't break, a lightweight, highly insulating core, and no polystyrene to absorb water. All inside a tough, beautiful fabric skin.

Inside: High strength, double the insulation, and no waterlogging

Modern spa covers can't get waterlogged because there's simply nothing in them that absorbs water the way foam covers do.  High strength is achieved using high-grade twinwall polycarbonate that stays strong year after year. And our engineered insulation pack uses commercial grade insulation and radiant air cavities to give you double the R-value in a lightweight package.

Outside: A tough, beautiful fabric covering

Every DuraCore cover comes with the most advanced polyester fabric of any spa cover. Made from solution-dyed fibers, it has a lifetime warranty against cracking.  Plus, there’s no need for regular treatment to maintain UV protection of your cover.

The best spa cover for the planet


Standard vinyl and foam spa covers waste a lot of energy over their short lives, then head to landfills where they sit for hundreds of years.  Modern covers last far longer, are made of 90% recyclable and reusable materials, and save literally tons of carbon over their lifetime.  

Plus Modern 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 20 tons of greenhouse gas emissions over its life.


Customize your cover:  Optional features you'll want to consider

Built-in solar heating

Built-in solar heating option brings the sun's heat from the top of the cover down into your spa, substantially reducing the electricity required for heating. Adds only three pounds of weight to the cover, and requires no special installation.   

Automatic snowmelt

This one-of-a-kind 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. 

Super Strength

Adds reinforcement to the inside of the cover to double the weight-bearing capability.  Recommended in heavy snow areas and where dogs or children may be on top of the cover frequently.

Cover lifters

A wide selection of quality cover lifts are available to match with your new spa cover.  All lifters are 20% off with the purchase of a cover.

SunCatcher's solar heating technology was awarded

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

Pool Spa Patio Expo First Place Award to Aztech for Best Green Product

A cover that actually 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:

Virtually unbreakable


Sometimes 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 500 pounds of weight with no problem.


Details, details ....

Buckles, straps, and handles are not afterthoughts for us.  We know that if your cover is going to last as long as your spa, you'll want to get every detail right. Our straps and handle connections are steel reinforced.  We use only high-strength center-release buckles that are easy to unlatch, and of course we have full ASTM F1346 compliance as a safety cover.  We'll send you a complete drawing and specification of your new cover for your approval.  Who else does that?  See more about our strap/handle options here.

Drop-in compatibility with all Hot Spring & Caldera spas.
