Watch it open and close on a cover lifter

Filmed at Southern Leisure Spas & Wellness in Texas, one of our authorized showrooms: the AIRCAP 1 folds back onto a standard cover lifter and closes again. It works with many manual cover lifters: see which lifters work, or ask us about yours.

Why the Small fits the Infinity (Estes LS-594)

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 Infinity (Estes LS-594)'s 85" x 85" shell with the right overhang.

At 85" the Infinity (Estes LS-594) is at the top of the Small's 83"–85" range — the largest cabinet this size covers. Measure before ordering: half an inch more and the cover you need is the Medium. Within Luxury Spas USA, the Infinity (Estes LS-594) shares that 85" x 85" cabinet with Galley, Savannah (WS-692) and Victoria — same footprint, same cover. The 10 Luxury Spas USA models we fit sit on 4 footprints, and the Infinity (Estes LS-594) is on number 3 of 4 from the smallest; together they span 3 of the six AIRCAP 1 sizes.

Cabinet dimensions can change between model years. Before ordering, measure your Infinity (Estes LS-594) 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 85" x 85" is on one page: hot tubs that take an 85" × 85" 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.

What customers are saying

Awesome product, my kids don’t complain about the cover anymore…

Thoughtfully engineered

Built to solve the
problems of foam.

Three practical reasons to rethink your next hot tub cover.

Water-resistant & lightweight

AirLoc™ panels have no foam core to soak up water, so the cover weighs the same out of the box and years later: 35–40 lb, depending on size.

Learn about water resistance

Consistent insulation

The sealed AirLoc™ air core has nothing in it to absorb water, so its insulation stays consistent for the life of the cover.

See how AIRCAP insulates

Replaceable skirt system

Three ZipTech™ skirt lengths come in the box, and a worn or damaged skirt can be replaced on its own, without replacing the whole cover.

Luxury Spas USA Infinity (Estes LS-594) cover: common questions

Need help? Contact thrml. to confirm your fit before you order.

What size hot tub cover fits the Luxury Spas USA Infinity (Estes LS-594)?

The Luxury Spas USA Infinity (Estes LS-594) takes the AIRCAP 1 Small, which fits square hot tubs measuring 83"–85" across. The Infinity (Estes LS-594)'s cabinet measures 85" x 85", 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 Luxury Spas USA Infinity (Estes LS-594)?

Yes — the Infinity (Estes LS-594)'s 85" x 85" 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 Luxury Spas USA Infinity (Estes LS-594) 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 Luxury Spas USA Infinity (Estes LS-594)?

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.
