89 x 89 Hot Tub Cover — Size, Fit and 47 Spas That Take It

A hot tub measuring 89" × 89" takes the AIRCAP 1™ Large, which fits square spas 89–91". That is the whole answer — but measure your own spa before ordering rather than trusting the size of the cover you are replacing, because cabinets vary between model years and a cover bought to the wrong number is the most common ordering mistake there is.

Measure straight across the top of the cabinet, edge to edge, both ways. If the two numbers differ, use the larger one. If you land between two sizes, round up: an oversized cover overhangs by a fraction, which is how a spa cover is meant to sit, while an undersized one will not seal along the edges.

Which hot tubs are 89" × 89"?

46 of the 1093 models in our Spa Fitter measure 89" × 89", across 11 brands, and 1 more rounds up to it (listed below). If yours is on this list, the size question is settled — click through for its own page.

Also rounds up to 89" × 89"

1 more model is not printed as an exact 89" square: one or both sides fall a fraction short. The rule is to round up, so it takes the same Large.

Brand	Rounds up to 89" × 89"
Vita Spa	Escapade (88.5" x 88.5", 0.5" short)

That makes 89" the 10th most common of the 18 square footprints in the Spa Fitter (47 of 1093, 4.3%); the most common is 84" × 84" with 257. Next door, 88" × 88" lists 16 and 90" × 90" lists 30 (plus 3 that round up). Beachcomber builds more at this size than anyone else — 18 of the 47, and every square Beachcomber model is this size.

What if my spa is not exactly 89"?

89" (226.1 cm) is the bottom of the Large band: anything from 89" to 91" takes the same cover, while 88" and under takes the Medium.

The Large covers everything from 89–91" across, so you do not need to hit 89" exactly. Outside that band, the AIRCAP 1™ comes in six sizes spanning 77" to 94" — the two-measurement guide will place you, or you can look your model up directly in the Spa Fitter.

One limit worth stating plainly: these are covers for square spas. If your cabinet is round, octagonal or a rectangle, no size here will fit it, and the alternatives guide covers what will.

Nearby measurements: 88" × 88" · 90" × 90" · 91" × 91". Every size from 77" to 94" has its own page, listed on the Spa Fitter.

What an 89" × 89" cover costs

The AIRCAP 1™ Large is $1,195 — the same price as every other size, including the pump, three Ziptech™ skirt depths and tie-down straps, with free shipping to all 50 states. There is no size surcharge, which is unusual in this category: most makers price a cover by its square footage, so a bigger spa costs more. For how that compares with foam and the other constructions, see what a hot tub cover costs.

It weighs 35–40 lb and, with no foam core to absorb water, never gains weight — the one number a foam cover cannot promise.

Frequently asked questions

What size cover fits an 89" x 89" hot tub?

An 89 inch square hot tub takes the AIRCAP 1 Large, which fits square spas 89 to 91 inches across. Measure straight across the top of your cabinet both ways and use the larger number; if it falls between two sizes, round up.

Which hot tubs are 89" x 89"?

46 models in our Spa Fitter measure 89 by 89 inches across 11 brands (Aquaterra Spas, Be Well Canada Spa, Beachcomber and 8 others), and one more rounds up to it. Each one has its own page listing the cover size it takes.

Is 89 inches the smallest spa a Large fits?

Yes. The Large covers square spas 89 to 91 inches across, so 89 is its lower limit; a cabinet of 88 inches or under takes the Medium instead.

How much does an 89" x 89" hot tub cover cost?

The AIRCAP 1 is $1,195 in every size, including the pump, three Ziptech skirt depths and tie-down straps, with free shipping to all 50 states. There is no size surcharge, so an 89 inch cover costs the same as the smallest one we make.
