Why the XX-Small fits the Soul

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 Soul's 78" x 78" shell with the right overhang.

At 78" the Soul sits mid-band in the XX-Small's 77"–79" range, 1" off the bottom and 1" off the top. Within Jacuzzi, the Soul shares that 78" x 78" cabinet with Echo — same footprint, same cover. Jacuzzi builds the 31 models we fit on 8 footprints, and the Soul is on the smallest of them; the line spans 6 of the six AIRCAP 1 sizes.

Cabinet dimensions can change between model years. Before ordering, measure your Soul 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 78" x 78" is on one page: hot tubs that take a 78" × 78" 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.

Jacuzzi Soul cover: common questions

What size hot tub cover fits the Jacuzzi Soul?

The Jacuzzi Soul takes the AIRCAP 1 XX-Small, which fits square hot tubs measuring 77"–79" across. The Soul's cabinet measures 78" x 78", 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 Jacuzzi Soul?

Yes — the Soul's 78" x 78" 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 Jacuzzi Soul 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 Jacuzzi Soul?

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.
