83 x 83 Hot Tub Cover — Size, Fit and 40 Spas That Take It

A hot tub measuring 83" × 83" takes the AIRCAP 1™ Small, which fits square spas 83–85". 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 83" × 83"?

34 of the 1093 models in our Spa Fitter measure 83" × 83", across 13 brands, and 6 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 83" × 83"

6 more models are not printed as an exact 83" square: one or both sides fall a fraction short. The rule is to round up, so they take the same Small.

Brand	Rounds up to 83" × 83"
Dynasty Spas	Club 7L (Bay Hill) (82.5" x 82.5", 0.5" short), Club 7N (Valhalla) (82.5" x 82.5", 0.5" short)
MAAX Spas	California Cooperage 311 (82.5" x 82.5", 0.5" short), California Cooperage 370 (82.5" x 82.5", 0.5" short), California Cooperage 371 (82.5" x 82.5", 0.5" short)
Riptide Spas	Heritage Tribute (82.5" x 82.5", 0.5" short)

That makes 83" the 11th most common of the 18 square footprints in the Spa Fitter (40 of 1093, 3.7%); the most common is 84" × 84" with 257. Next door, 82" × 82" lists 68 (plus 8 that round up) and 84" × 84" lists 244 (plus 13 that round up). Superior Wellness builds more at this size than anyone else — 8 of the 40; its other 34 square models sit at 79" × 79", 84" × 84", 87" × 87", 88" × 88", 91" × 91".

What if my spa is not exactly 83"?

83" (210.8 cm) is the bottom of the Small band: anything from 83" to 85" takes the same cover, while 82" and under takes the X-Small.

The Small covers everything from 83–85" across, so you do not need to hit 83" 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: 82" × 82" · 84" × 84" · 85" × 85". Every size from 77" to 94" has its own page, listed on the Spa Fitter.

What an 83" × 83" cover costs

The AIRCAP 1™ 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 83" x 83" hot tub?

An 83 inch square hot tub takes the AIRCAP 1 Small, which fits square spas 83 to 85 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 83" x 83"?

34 models in our Spa Fitter measure 83 by 83 inches across 13 brands (Aquavia Spa, Be Well Canada Spa, Clearwater Spas and 10 others), and 6 more round up to it. Each one has its own page listing the cover size it takes.

Is 83 inches the smallest spa a Small fits?

Yes. The Small covers square spas 83 to 85 inches across, so 83 is its lower limit; a cabinet of 82 inches or under takes the X-Small instead.

How much does an 83" x 83" 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 83 inch cover costs the same as the smallest one we make.
