MAAX Spas Replacement Hot Tub Covers

MAAX Spas numbers its own hot tubs rather than naming them. Today they are sold as American Whirlpool, a brand MAAX Spas launched in January 2018 with 24 of its existing models. Before that, MAAX sold its own MAAX Collection line and California Cooperage hot tubs, and a few of the older California Cooperage numbers were later reused on different American Whirlpool tubs, so the badge on your tub matters. MAAX Spas also builds Vita Spa hot tubs, which have names rather than numbers; they are on our Vita Spa page. Our fitter lists twenty-four models: fifteen American Whirlpool models, three retired MAAX Collection models and six retired California Cooperage models. The 460 and 461 are the most compact at 78 inches square. The California Cooperage 311, 370 and 371 measure 82.5 inches, and the American Whirlpool 171, 270 and 271 measure 83 inches. The 470, 471 and 472 measure 87 inches, and the California Cooperage 280, 380 and 381 measure 91 inches. The largest are the 480, 481 and MAAX Collection 482, 780 and 781 at 91.5 inches, and the American Whirlpool 280, 281, 282, 880 and 881 at 92 inches.

Here is how the 24 MAAX Spas models in our fitter map to AIRCAP 1™ sizes:

• The Model 460 (2025 and earlier) and Model 461 (2025 and earlier) each take the AIRCAP 1™ XX-Small, which fits square spas 77–79".
• The Model 171, Model 270, Model 271, California Cooperage 311, California Cooperage 370 and California Cooperage 371 each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Model 470, Model 471 and Model 472 each take the AIRCAP 1™ Medium, which fits square spas 86–88".
• The California Cooperage 280, California Cooperage 380 and California Cooperage 381 each take the AIRCAP 1™ Large, which fits square spas 89–91".
• The Model 280, Model 281, Model 282, Model 480, Model 481, Model 880, Model 881, MAAX Collection 482, MAAX Collection 780 and MAAX Collection 781 each take the AIRCAP 1™ X-Large, which fits square spas 92–94".

Every AIRCAP 1™ ships with the Ziptech™ modular skirt system, so you can zip on the right skirt depth for your cabinet instead of ordering a custom cover.

A note on the 91.5" models, the 480 and 481 and the MAAX Collection 482, 780 and 781: 91.5 inches falls half an inch below the X-Large range and half an inch above the Large. Round up. An X-Large overhangs by a fraction, which is how a cover is meant to sit; a Large would come up short and never seal properly along two edges.

460 and 461 owners: check which shell you have. American Whirlpool printed the 460 and 461 at 78" square through 2025, and those tubs take the XX-Small. For 2026 both moved to a new rectangular shell, printed 82" x 69.5", and no square AIRCAP 1™ fits it. American Whirlpool’s website switched to the new shell in spring 2026, so a tub bought around the 2025–26 winter could be either. Measure two sides: the earlier tub is about 78" both ways, the newer one 82" one way and 69.5" the other.

470, 471 and 472 owners: check which shell you have. American Whirlpool has moved the 470, 471 and 472 to new shells and still prints them at 87" square, which takes the Medium. Our pictures show the earlier shell, which has big rounded corners. The spec sheets for the new shells are unchanged from the earlier ones, so if yours has the newer shell (tight corners, a flat raised rim and a large swirl-logo plate in the footwell floor; first shown by American Whirlpool in October 2026), measure it before ordering.

The 880 and 881. The American Whirlpool 880, added to the 800 Series in 2021, is printed 92" square and takes the X-Large. American Whirlpool also gave the 881 a new shell during 2021. Our 92" size and picture are for that shell, which has its lounge along a side wall. On the earlier 881 the lounge runs along the front, the control-panel side, and we have not found a printed size for that shell, so if yours is one, measure before ordering.

MAAX Collection owners. Before American Whirlpool, MAAX sold several of these numbers as MAAX Collection models. MAAX’s brochures print the MAAX Collection 482, 780 and 781 at 91.5" square, which rounds up to the X-Large. MAAX’s 2016 brochure prints the MAAX Collection 461 at 78" square (XX-Small), the 470, 471 and 472 at 88" square (Medium) and the 480 and 481 at 91.5" square (X-Large), the same AIRCAP 1™ sizes as the Model rows with those numbers. The 482, 780 and 781 numbers may also have been used on MAAX Collection tubs before 2010 that we have not seen, so if your tub does not match the picture, measure before ordering. The MAAX Collection 581 is not in our fitter yet: its printed 91.5" is measured across a channel that runs around the outside of the top, and the cover sits on the raised rim inside it, which MAAX does not print. Measure that rim before ordering.

California Cooperage owners: check the badge. MAAX’s 2014 and 2015 California Cooperage brochures print the 311, 370 and 371 at 82.5" square, which rounds up to the Small, and the 380 and 381 at 91" square, which takes the Large. Before 2014 California Cooperage also sold a 170, 171, 270, 271, 280 and 281, and at least three of those numbers were later reused on different American Whirlpool tubs:

• A California Cooperage 280 is printed 91" square and takes the Large, so use the California Cooperage 280 row, not the Model 280, which is today’s 92" American Whirlpool tub and takes the X-Large. The California Cooperage 280 and the later 380 share a 91" footprint but are different shells, so each has its own picture.
• The California Cooperage 270 sold before 2014 was a rectangle, printed 208 x 195 cm, and no AIRCAP 1™ fits it. Do not order from the Model 270 row for it: that row is today’s 83" square American Whirlpool 270.
• The California Cooperage 281 sold before 2014 is a smaller tub than today’s 92" Model 281. The only size we have found for it is metric: MAAX’s 2013 European brochure prints it at 225 cm square, about 88.6 inches, so it is not in our fitter yet. Measure before ordering.

The only sizes we have found for the earlier California Cooperage 171 and 271 are metric (213 cm square in MAAX’s 2013 European brochure), so measure one of those before ordering too.

Models the AIRCAP 1™ does not fit: the American Whirlpool 100, 160 and 261 are smaller than 77 inches, and the 101, 151, 250, 451, 890 and 982 are rectangular, as are the 2026-and-later 460 and 461. Among retired models, the MAAX Collection 351 (64 x 81") and 811 (90 x 114") and the California Cooperage M50 (82 x 69"), M61 (79 x 72"), M71 (83 x 73") and 101 (84 x 48") are rectangles, as were the California Cooperage 170 and 270 sold before 2014 (208 x 195 cm). The MAAX Collection 705 is printed 90 x 92", two inches out of square, the California Cooperage 103 is round, and the California Cooperage 102 is a corner spa. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.

Measure your own spa before ordering — cabinet sizes can change between model years. The SureFit™ measuring guide walks through it in two measurements, and works for any square hot tub from 77″ to 94″, MAAX Spas or not.
