Sundance Spas Replacement Hot Tub Covers

Sundance Spas names its ranges by series number — 980, 880, 780 and 680 — alongside the Sundance Splash and Select ranges and a line of Sundance swim spas, and the square models across them fit an AIRCAP 1™. The Berkeley and Brook, at 78" square, are the most compact of the twenty-three and take the XX-Small. The Prado 680 (2023 and later), at 80" square, takes the X-Small. The Vistamar and the 2024-and-later Altamar 880, Bristol and Hanover 780, and Edison and Peyton 680 take the Small. The Constance and Victoria, the Hartford 680 and the 2012-and-earlier Chelsee 780 take the Medium. The Optima and Cameo 880, the 2013-and-later Chelsee and Hamilton 780, Ramona and McKinley 680, and the Lisbon and Odessa 980 take the Large. The Hawthorne 680 and the 2012-and-earlier Hamilton 780, both 92" square, take the X-Large.

Here is how the 23 Sundance Spas models in our fitter map to AIRCAP 1™ sizes:

• The Berkeley and Brook each take the AIRCAP 1™ XX-Small, which fits square spas 77–79".
• The Prado 680 (2023 and later) takes the AIRCAP 1™ X-Small, which fits square spas 80–82".
• The Vistamar 880, Altamar 880 (2024 and later), Bristol 780, Edison 680, Peyton 680 and Hanover 780 each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Chelsee 780 (2012 and earlier), Hartford 680, Constance Select and Victoria Select each take the AIRCAP 1™ Medium, which fits square spas 86–88".
• The Optima 880, Cameo 880, Chelsee 780 (2013 and later), Hamilton 780 (2013 and later), Ramona 680, McKinley 680, Lisbon 980 and Odessa 980 each take the AIRCAP 1™ Large, which fits square spas 89–91".
• The Hamilton 780 (2012 and earlier) and Hawthorne 680 each take the AIRCAP 1™ X-Large, which fits square spas 92–94".

Two Sundance naming points worth knowing before you order. First, Sundance Splash is two different things: the Splash Series is a line of hot tubs that includes the 78" square Berkeley and Brook listed above and the rectangular Paisley, while the Sundance 12 Splash is a twelve-foot swim spa that no square cover fits. Both Berkeley and Brook are sold in 30-jet and 40-jet versions on the same 78" shell, so either takes the same cover. Second, the Constance and Victoria were sold as Elite Series models before about 2012 and as Select Series afterward. It is the same 88" square cabinet either way — the seating, jets and volume changed over the run, the footprint did not — so whichever badge is on yours, the Medium is the right cover.

Altamar and Prado owners: check the year. Sundance reused both names for new, square tubs. The Altamar 880 was an 81" x 86" rectangle up to the 2023 model year; the square 84" x 84" Altamar arrived for 2024 and takes the Small. The Prado 680, and the Prado 5 built on the same shell, was a 76" x 84" rectangle from 2017 to 2022; the square 80" x 80" Prado arrived for 2023 and takes the X-Small. No square cover fits the older rectangles. The model year on your spa decides it, not the delivery date: any Prado delivered in 2022 or 2023, or any Altamar delivered in 2023 or 2024, could be either. The quickest check is to measure both sides of the top — if they differ by more than an inch, yours is the older tub.

Chelsee and Hamilton owners: check the year, then measure. Sundance changed its 780 Series for the 2013 model year, and the Hamilton moved to a new, smaller shell. Sundance's guides printed the Hamilton 780 at 92" square up to the 2012 model year, so that tub takes the X-Large; the Hamilton from 2013 on is printed at 89" square and takes the Large. Sundance printed the Chelsee 780 at 88" square up to 2012, so that tub takes the Medium; from 2013 Sundance prints it at 89" square, which takes the Large. As with the Altamar and Prado, the model year decides it, not the delivery date, so a Chelsee or Hamilton delivered in 2012 or 2013 could be either. The two Hamiltons are three inches apart; the two Chelsees are only about an inch apart and look the same from above. So if yours is from before 2014, or you are not sure of its year, measure straight across the top, edge to edge, both ways, before ordering. Match the larger number to a size, rounding any fraction up: 86–88" takes the Medium, 89–91" the Large and 92–94" the X-Large.

Older Sundance 680 models. The list above also includes two 680 Series tubs Sundance sold from about 2007 to 2014, sized from Sundance's own pre-delivery guides: the Hartford 680, 88" square, takes the Medium, and the Hawthorne 680, 92" square, takes the X-Large. Both sit at the edge of their size, so measure straight across the top, edge to edge, both ways, before ordering. Match the larger number to a size, rounding any fraction up: 86–88" takes the Medium, 89–91" the Large and 92–94" the X-Large.

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.

Not every Sundance Spas model takes a square cover. The Aspen 880, Claremont 980 and Kingston 980 are large rectangles that run past the 94" ceiling; the Marin 880 and Montclair 780 are rectangular too — Sundance itself describes the Marin's shape as non-traditional; and the Capri 880, Dover 780 and Alicia 680 are compact rectangles whose short side sits below the 77" floor, as are the Prado 680 and Prado 5 up to the 2022 model year (76" x 84"). The Altamar 880 up to the 2023 model year is a rectangle too, at 81" x 86", as explained above. The swim-spa line — the Sundance 12 Splash, 13 Stream, 17 Stream and 17 Surf — runs 12 to 17 feet long, far beyond any square cover. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.

Several other Sundance models, most of them older, are not square either. The Maxxus 880 (about 90–91" x 110") is a large rectangle past the 94" ceiling. The Certa 780, Majesta 880 and 2009-and-later Burlington 680 (all 81" x 86"), the Camden 780 (76" x 83"), the Cambria 880 (76" x 91", not the Cameo 880 listed above), the Paisley from the Splash Series (68" x 78") and the Caprio, Metro, Solo and Tango from the Portofino Series are all rectangles. The Denali 680 is round: it measures 78.5" across, inside the XX-Small's range, but no square cover fits a round tub. The Tacoma 680 is a 68" corner (triangular) tub. Sundance's July 2007 pre-delivery guide printed an earlier Burlington at 7 feet by 7 feet. We have not been able to confirm that tub's shape, so it is not in our list. If your Burlington is from 2008 or earlier, first check that its top is a square with four straight sides — two equal measurements do not prove it, since a round or corner tub measures the same both ways — and only then size it with the SureFit™ measuring guide below.

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″, Sundance Spas or not.
