Superior Wellness Platinum Monaco Replacement Cover

The Superior Wellness Platinum Monaco takes the AIRCAP 1™ XX-Small — a foam-free replacement hot tub cover for square spas 77"–79". The Platinum Monaco's cabinet measures 79" x 79", inside the XX-Small's range. The cover weighs 35–40 lb for life, costs $1,195, is engineered to comply with ASTM F1346-23, and carries a 3-year limited warranty.

Why the XX-Small fits the Platinum Monaco

The AIRCAP 1™ comes in six sizes covering square spas from 77" to 94". Each size is built to overhang its band slightly — that is how a spa cover is meant to sit — so the XX-Small, which fits cabinets 77"–79", covers the Platinum Monaco's 79" x 79" shell with the right overhang.

At 79" the Platinum Monaco is at the top of the XX-Small's 77"–79" range — the largest cabinet this size covers. Measure before ordering: half an inch more and the cover you need is the X-Small. Within Superior Wellness, the Platinum Monaco shares that 79" x 79" cabinet with Platinum Florence, Platinum Happy, Platinum Holiday Let 5 and Platinum Marseille — same footprint, same cover. Superior Wellness builds the 42 models we fit on 7 footprints, and the Platinum Monaco is on the smallest of them; the line spans 4 of the six AIRCAP 1 sizes.

Cabinet dimensions can change between model years. Before ordering, measure your Platinum Monaco at its widest point across the top, in both directions, including any acrylic lip that overhangs the cabinet — the SureFit™ guide walks through it in two measurements. If a figure you have found elsewhere is larger than ours, an overhanging lip is the usual reason. If your spa measures between two sizes, round up.

Every spa in our catalogue that measures 79" x 79" is on one page: hot tubs that take a 79" × 79" cover — the same AIRCAP 1™ XX-Small, at the same price.

How the AIRCAP 1™ is built

Instead of a rigid foam core wrapped in vinyl, the AIRCAP 1™ uses welded drop-stitch construction: a sealed air chamber with no foam to absorb water, so it does not become the waterlogged two-person lift that ends most foam covers. More on how it insulates, how it holds up, and why it is foam-free — or estimate what your current foam cover weighs.

Superior Wellness Platinum Monaco cover: common questions

What size hot tub cover fits the Superior Wellness Platinum Monaco?

The Superior Wellness Platinum Monaco takes the AIRCAP 1 XX-Small, which fits square hot tubs measuring 77"–79" across. The Platinum Monaco's cabinet measures 79" x 79", inside that band. Measure your spa side to side across the top of the cabinet to confirm before ordering.

Will the AIRCAP 1 fit a Superior Wellness Platinum Monaco?

Yes — the Platinum Monaco's 79" x 79" square cabinet falls in the AIRCAP 1 XX-Small's 77"–79" range, and the Ziptech modular skirt system ships with three skirt lengths so the drop over the cabinet adjusts without a custom order. Cabinet sizes can change between model years, so confirm with two quick measurements.

How much does a replacement cover for the Superior Wellness Platinum Monaco cost?

The AIRCAP 1 costs $1,195 in every size, including the pump, three Ziptech skirt lengths, and tie-down straps, with free US shipping and 30-day returns. Unlike a foam cover it has no foam core to waterlog, so it stays at its original 35–40 lb weight for life.

How heavy is a replacement cover for the Superior Wellness Platinum Monaco?

The AIRCAP 1 XX-Small weighs 35–40 lb and keeps that weight permanently — its sealed drop-stitch air core cannot absorb water. A foam cover starts at 40–75 lb and gains weight as the foam saturates.
