What size AIRCAP 1™ fits your QCA Spas hot tub?
QCA Spas has built hot tubs in DeWitt, Iowa since 1966, and its square shells sit on just four footprints, which keeps cover sizing simple. At 92" × 92" the Moonstone Deluxe, Capricorn and Aquarius — and the discontinued Majestic-series Supreme PM and Supreme XLP — take the AIRCAP 1™ X-Large (fits 92"–94"). At 87" × 87" the Diamond Deluxe and the Diamond (the Majestic Ultra XLP, sold under that name today), plus the discontinued Ultra and Coral Deluxe, take the Medium (86"–88"). The Pisces and Gemini at 85" and the Gemstone Deluxe, Island PM, Island XLP, Topaz and Ruby at 84" take the Small (83"–85"). The Libra, Libra 110, Scorpio and Scorpio 110 are 78" × 78" and take the XX-Small (77"–79"); the 110 models are the 110-volt plug-and-play versions of the same shells.
Seven current QCA models are rectangles and no AIRCAP 1™ size will fit them: the Jade Deluxe and Jade 110 (84" × 67" on the product page, 82" × 65" in the catalog), Amber Deluxe and Amber 110 (84" × 72"), Aries 110 (78" × 60") and the Leo and Leo 110 (78" × 68"). The discontinued Opal Deluxe (93" × 73") is also a rectangle, and QCA’s swim spas are 92" wide by 13 to 19 feet long. If you own one of these, a square cover is the wrong purchase at any price.
Dimensions are taken from QCA’s product pages and its 2026 Spa Collection catalog for current models, and from the 2024 condensed line-up catalog on qcaspas.com for the discontinued Majestic and Jewel models (September 2026). Cabinet sizes can change between model years, so measure your spa side to side across the top of the cabinet before ordering; the SureFit™ measuring guide walks through it in two measurements. If your measurement falls between two sizes, round up.
