80 x 80 Hot Tub Cover — Size, Fit and 35 Spas That Take It

A hot tub measuring 80" × 80" takes the AIRCAP 1™ X-Small, which fits square spas 80–82". 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 80" × 80"?

32 of the 1093 models in our Spa Fitter measure 80" × 80", across 13 brands, and 3 more round 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 80" × 80"

3 more models are not printed as an exact 80" square: one or both sides fall a fraction short. The rule is to round up, so they take the same X-Small.

Brand	Rounds up to 80" × 80"
Dr. Wellness Spas	STR-34 (79.5" x 79.5", 0.5" short)
Hudson Bay Spas	HB29 (HB-2900) (79.5" x 79.5", 0.5" short), HB34 (HB-3400) (79.5" x 79.5", 0.5" short)

That makes 80" the 13th most common of the 18 square footprints in the Spa Fitter (35 of 1093, 3.2%); the most common is 84" × 84" with 257. Next door, 79" × 79" lists 34 (plus 5 that round up) and 81" × 81" lists 9 (plus 9 that round up). DreamMaker Spas and Hydropool Hot Tubs build the most at this size — 8 each of the 35.

What if my spa is not exactly 80"?

80" (203.2 cm) is the bottom of the X-Small band: anything from 80" to 82" takes the same cover, while 79" and under takes the XX-Small.

The X-Small covers everything from 80–82" across, so you do not need to hit 80" 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: 79" × 79" · 81" × 81" · 82" × 82". Every size from 77" to 94" has its own page, listed on the Spa Fitter.

What an 80" × 80" cover costs

The AIRCAP 1™ X-Small 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 80" x 80" hot tub?

An 80 inch square hot tub takes the AIRCAP 1 X-Small, which fits square spas 80 to 82 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 80" x 80"?

32 models in our Spa Fitter measure 80 by 80 inches across 13 brands (AquaLife Spas, Aquaterra Spas, Catalina Spas and 10 others), and 3 more round up to it. Each one has its own page listing the cover size it takes.

Is 80 inches the smallest spa an X-Small fits?

Yes. The X-Small covers square spas 80 to 82 inches across, so 80 is its lower limit; a cabinet of 79 inches or under takes the XX-Small instead.

How much does an 80" x 80" 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 80 inch cover costs the same as the smallest one we make.
