Are you tired of replacing Spa Covers that just get too heavy to lift? Or Hot Tub Covers that saturate or break? The SpaCap's patented design makes using your Swim Spa, or Hot Tub as easy as getting into bed.

These hot tub covers are used exclusively at the #1 Hotel in America according to Forbes. The San Ysidro Ranch

If you have owned your swim spa or hot tub for a while you most likely have gone through a few traditional rigid foam filled covers.

It's not you, it's them.


On a regular size hot tub it can be hard to manage, but on a Swim Spa it can be downright dangerous.

It's not due to rain water or snow so a tapered cover isn't going to make any difference. It's because of the steam coming off the water in your swim spa or hot tub. It soaks into the foam and then condenses, the water molecules are bigger than steam and they get trapped in the foam. SLOWLY the hot tub cover gets heavier.

What's worse is that on a swim spa, because of all the sections it typically happens to each section at different rates. You have to replace your cover or try to maneuver the heavy sections around so you can still use your spa. Eventually you can't use your spa BECAUSE IT'S TOO MUCH OF A STRUGGLE.

That's why SpaCap hot tub covers were invented, literally!

Compare the materials used on SpaCap Swim Spa Covers and Hot Tub Covers to those on a traditional foam filled hot tub covers.

All SpaCap Hot Tub Covers have Sunbrella Marine Fabric

Vinyl vs Sunbrella

Traditional foam filled hot tub covers have vinyl on the outside. The cheapest material available that still LOOKS like it might be quality ALL VINYL USED ON TRADITIONAL FOAM FILLED HOT TUB COVERS IS RATED BY HOURS OUTDOORS.

SpaCap hot tub covers are covered with Sunbrella Marine fabric, the best outdoor fabric on the planet, RATED BY YEARS OUTDOORS! We have seen Sunbrella still look like new after twelve years of constant exposure to the elements.

You will never get a rigid foam filled hot tub cover to last anywhere NEAR that long.

Foam vs Air Chambers

Traditional hot tub covers all use foam and claim the R-value of that foam as it's insulation value. But that rating is specific to the foam being used in a dry environment! It does not apply when the foam is used in a wet environment, say over a steam supply.

SpaCap Swim Spa Covers and Hot Tub Covers don't use foam so there is nothing to suck up the steam.

That means there is nothing to get heavy.

SpaCap Hot Tub Covers are easy to use and stay that way!

Recently one of our customers reported that her new swim spa cover
was easy enough for her to use with one hand.

Plus, since the bottom of the SpaCap rests right on the water surface, it starts insulating the water instead of trying to insulate from several inches above the water. This also cuts down on evaporation/condensation that will always be going on under a foam cover so your spa chemistry stays more stable.

For the past thirty years we have sold SpaCap Hot Tub Covers all over the world from The Colorado Rockies, to the French Alps. When snow fall is making the news and traditional spa covers are cracking under the weight, SpaCap Hot Tub Covers are just fine.

Hot Tub Covers vs Snow Load

The SpaCap Hot Tub Covers can also handle more wind than any other hot tub cover. After years selling covers in areas that get Hurricanes and tornados, not even ONE of our SpaCap Hot Tub Covers have ever blown away.

  • 1. Make sure hot tub is filled to proper amount. The Proper amount is whatever the spa manufacturer suggests the spa water to be for proper operation of the spa. The SpaCap rests right on the water surface so make sure your spa has water in it.

  • 2. Distinguish the top from the bottom and observe the location of the valves. The top is the side of the Spacap that shows when it is on the spa. The bottom is the side with the valves on it. When the SpaCap is on the spa, the bottom will rest on the water.

  • 3. Place the SpaCap on spa, laying it on water surface. Top side up. You are meant to fold the cover back to expose the valves to fill the SpaCap.

    Note: Valves are meant to be on underside when cover is on hot tub.

  • 4. Inflation. Open the flap of the valve you intend to put air in. Prop open the inner check valve with a plastic funnel. The funnel will also divert the air into the cover. In order to put air into the SpaCap you need something that moves a volume of air. For example a shop vac that has an exhaust port you can hook the hose into or a leaf blower. An air compressor would work but it will take longer since it is designed to move air under pressure. The SpaCap is not designed to be under pressure.

    Inflate the "Top" valve first until there is about eight inches of air. Inflate the bottom unmarked chamber to desired level. We recommend using a shop vac to inflate your SpaCap.

  • 5. Close valves and center the cover on the spa so that it evenly covers the entire hot tub.

  • 6. Place fasteners as needed. You may choose not to install the fasteners, but they do help the Spa Cap keep its shape, insulate better and keep the moisture running off. The fasteners should be equally spaced and should go below the acrylic of the spa. If your spa has a wood lip that protrudes further then the acrylic the fasteners should go about three inches below the wood lip. If as you are installing the fasteners the cover becomes difficult to fasten on the last side, you have too much air in the cover. There should still be a little give in the cover when fastened and the corners should not be lifting.

  • 7. Congratulations on the purchase of your new SpaCap cover! Yes, it is different, but it works better than any other cover on the market.
