Aahs Spas 3000 Replacement Cover

The Aahs Spas 3000 takes the AIRCAP 1™ Small — a foam-free replacement hot tub cover for square spas 83"–85". The 3000's cabinet measures 84" x 84", inside the 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 Small fits the 3000

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 Small, which fits cabinets 83"–85", covers the 3000's 84" x 84" shell with the right overhang.

At 84" the 3000 sits mid-band in the Small's 83"–85" range, 1" off the bottom and 1" off the top. Within Aahs Spas, the 3000 shares that 84" x 84" cabinet with 2000, Bahama and Hawaiian — same footprint, same cover. Aahs Spas builds the 9 models we fit on 4 footprints, and the 3000 is on number 2 of 4 from the smallest; the line spans 3 of the six AIRCAP 1 sizes.

Cabinet dimensions can change between model years. Before ordering, measure your 3000 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 84" x 84" is on one page: hot tubs that take an 84" × 84" cover — the same AIRCAP 1™ 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.

Aahs Spas 3000 cover: common questions

What size hot tub cover fits the Aahs Spas 3000?

The Aahs Spas 3000 takes the AIRCAP 1 Small, which fits square hot tubs measuring 83"–85" across. The 3000's cabinet measures 84" x 84", inside that band. Measure your spa side to side across the top of the cabinet to confirm before ordering.

Will the AIRCAP 1 fit an Aahs Spas 3000?

Yes — the 3000's 84" x 84" square cabinet falls in the AIRCAP 1 Small's 83"–85" 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 Aahs Spas 3000 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 Aahs Spas 3000?

The AIRCAP 1 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.
