What size AIRCAP 1™ fits your Alps Spas hot tub?
Alps Spas builds its square hot tubs in just two footprints, which makes finding a replacement cover straightforward. The Classic Series Rainier and Himalaya, together with the Q-Series Q-SL, Q-DL and Q-OS, all measure 84 inches square. The larger Q-90, K2 and Everest all measure 90 inches square.
That maps to exactly two AIRCAP 1™ sizes:
- The Alps Rainier, Himalaya, Q-SL, Q-DL and Q-OS each measure 84" × 84", so they take the AIRCAP 1™ Small, which fits 83–85" spas.
- The Alps Q-90, K2 and Everest each measure 90" × 90", so they take the AIRCAP 1™ Large, which fits 89–91" spas.
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.
Not seeing your model? The Alps Innsbruck is rectangular, the Ciara measures 82" × 77.5", and the Party Spa, Trainer and Denali are swim and exercise spas — none of them square, so they fall outside the AIRCAP 1™ range. Use the SureFit™ measuring guide to check any hot tub against our sizes.
