Completely different, inside and out

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


DuraCore Solar core module

Inside: High strength, lightweight 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 packs use commercial grade insulation and radiant air cavities to give you up to double the R-value in a lightweight package.

Outside: A tough, beautiful fabric covering

We use the most advanced polyester fabric of any spa cover. It's the same material that's used for awnings and boat covers, and there’s no need for any treatment to maintain the 10 year UV protection.  Liquid water is repelled by the tight weave of the fabric, yet it's fully breathable to keep your cover dry on the inside year after year.   Best of all, you can easily replace the fabric to extend the life of your cover to 15+ years.

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.


Choose the model that's right for your spa

The thinnest and lightest spa cover on the market, the LT is perfect for mild climates, summer use, sheltered spaces, or just to keep out debris and limit access.


Makes no compromises.  Highest insulating value plus true walk-on strength for serious winter climates and where durability is most important.


For colder climates that get typically get snow and temperatures below freezing in the winter. 


Turns your spa into a renewable energy powerhouse by bringing the sun's heat right into your spa water.

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 a DuraCore Solar and Super can handle 500 pounds of weight with no problem.


To us, the little things are a big deal

Handles where you want them, how you want them. Straps that hold fast.  Custom skirt lengths, or no skirt at all.  If you’re going to have your cover a long time, you should get it the way you want. Skid plates, rollaway wheels, gazebo handles and hurricane straps—we have a lot of ways to get your cover just right.  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.

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:
