Awesome product, my kids don’t complain about the cover anymore…
Best $$ I ever spent!

For a reasonable price, I can cover my spa with a top that won’t get musty.

Installation was a breeze and we love it already!
Great customer service still matters, and frankly, not enough companies deliver it anymore. This company does, and that deserves recognition.

Thoughtfully engineered
Three practical reasons to rethink your next hot tub cover.
AirLoc™ panels have no foam core to soak up water, so the cover weighs the same out of the box and years later: 35–40 lb, depending on size.
Learn about water resistanceThe sealed AirLoc™ air core has nothing in it to absorb water, so its insulation stays consistent for the life of the cover.
See how AIRCAP insulatesThree ZipTech™ skirt depths come in the box, and a worn or damaged skirt can be replaced on its own, without replacing the whole cover.

Aahs Spas builds to order in a small number of square footprints, which makes cover matching simple. Nine of its twelve models fall inside the AIRCAP 1™ range: the 2000, 3000, Bahama and Hawaiian all share an 84" footprint; the 4000, 5000 and 6000 share a 90"; the Luxor is the largest at 91"; and the Aruba is the most compact we fit at 79".
Here is how the 9 Aahs Spas models in our fitter map to AIRCAP 1™ sizes:
Aahs builds each spa to order — the number of pumps and the placement of every jet change from one build to the next — but the shell is molded, so the cabinet footprint does not. Two Aahs spas can differ by thirty jets and still take exactly the same cover. The Aruba is the one to measure before you order: at 79" × 78" it is an inch off square and sits right at the top of the XX-Small range, so the cover is sized from its longer side.
Stone Creek Spas owners. Mountain Spas Etc. of Conifer, Colorado lists this line as Stone Creek Spas, with Aahs’s model names and the same printed length and width, except that the Luxor is called the Fiji. The Fiji is the Luxor: Mountain Spas pictures it with Aahs’s own Luxor photo and prints the same 91" × 91". If your Stone Creek spa carries one of these model names, use the Aahs model of the same name; a Fiji takes the AIRCAP 1™ Large, like the Luxor. The Hawaiian has a very similar seat layout to the Luxor but is a smaller spa, so measure: about 84" across takes the AIRCAP 1™ Small, about 91" the AIRCAP 1™ Large. At 91" the Luxor and Fiji sit at the top of the Large range, so if yours measures more than 91" either way, it needs the AIRCAP 1™ X-Large.
Kona, Laguna, Molokai and Maui owners: measure first. These older Aahs models are not in today’s lineup. All four look square in Aahs’s own overhead photos, posted in 2020, but we have found no printed size for any of them, so they are not in our fitter. The Maui has a very similar seat layout to the Bahama, but its rim is molded differently, so do not assume it takes the Bahama’s size. Measure across the top of the cabinet both ways before ordering: if the two measurements are within an inch of each other and the longer one is between 77 and 94 inches, choose the size from the longer one.
Every AIRCAP 1™ ships with the Ziptech™ modular skirt system, so you can zip on the right skirt depth for your cabinet instead of ordering a custom cover.
Aahs models the AIRCAP 1™ does not fit. The Oahu is the one to watch: it is published as 76" × 76", two equal numbers that look square, but it is an octagon — a retro eight-sided shell with a round footwell — and a square cover cannot sit on it. At 76" it is also an inch under our 77" minimum, so it is out twice over. The Bali (84" × 72") and the Kauai (80" × 61") are rectangles rather than squares, and no square cover fits either. Two older Aahs models are out as well: the Hilo is round, and the Lani is a narrow two-person spa about twice as long as it is wide. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.
Measure your own spa before ordering — cabinet sizes can change between model years. The SureFit™ measuring guide walks through it in two measurements, and works for any square hot tub from 77″ to 94″, Aahs Spas or not.
