Thoughtfully engineered
Built to solve the
problems of foam.
Three practical reasons to rethink your next hot tub cover.
Consistent insulation
The sealed AirLoc™ air core has nothing in it to absorb water, so its insulation stays consistent for the life of the cover.

Three ZipTech™ skirt depths come in the box, and a worn or damaged skirt can be replaced on its own, without replacing the whole cover.

What size AIRCAP 1™ fits your Master Spas hot tub?
Master Spas builds the LSX, Twilight (TS), Balance, Precision, Healthy Living and Bar Harbor ranges, and forty-eight models fall inside the AIRCAP 1™ range — including its Healthy Living, Legacy Whirlpool and Contractor Series lines, each sold through its own channel. The compact end is the busiest: the Balance 6, Balance 6 CS, L6, S6 and TS 6.2 all sit on a 78" cabinet. The 7-series cabinets — LSX 700, TS 7.2, TS 7.25, Balance 7, Precision 7, LH L7 and LH S7 — share one footprint, the Bar Harbor LE and SE take the same Small cover, and the 8-series cabinets in our list share the largest.
Here is how the 48 Master Spas models in our fitter map to AIRCAP 1™ sizes:
- The Balance 6, Balance 6 CS, L6, S6, TS 6.2, HL 620L, HL 630L and LH 6 each take the AIRCAP 1™ XX-Small, which fits square spas 77–79".
- The LSX 700, TS 7.2, TS 7.25, Balance 7, Precision 7, LH L7, LH S7, HL 7, HL 7.5, LW Enterprise, LW Inspire, LW 730L, LW 7.2, CS Exeter, CS Cape Cod, LH 7, MPL 700, Bar Harbor LE and Bar Harbor SE each take the AIRCAP 1™ Small, which fits square spas 83–85".
- The LSX 30, LSX 800, LSX 850, TS 8.2, TS 8.25, Balance 8, Precision 8, HL 8, HL 8.5, HL 8 DL, LW Intrepid, LW Acclaim, LW 8.2, LW 8.25, CS Portsmouth, CS Windsor, TS 8.3, TS 8.35, MPL 800, MPL 850 and MPL LSX 30 each take the AIRCAP 1™ X-Large, which fits square spas 92–94".
Trim and seating suffixes don’t change the cover. The Balance 6 CS shares its 78" footprint with the Balance 6, the Bar Harbor LE and SE share one cabinet, and the TS 7.2 and TS 7.25 — like the TS 8.2 and TS 8.25 — differ inside the shell, not in footprint, so each pair takes the same AIRCAP 1™.
Bar Harbor owners: size from the top, not the brochure. Master Spas publishes the Getaway Bar Harbor LE and SE at 86" x 86", and its owner’s manuals at 87", but the manual’s own footnote explains that for its molded Getaway tubs those figures are the largest size a tub can come out at, rounded up to the inch. Across the top, where the cover sits, the Bar Harbor measures about 83–85" with large, rounded 12" corners, and the OEM-labeled replacement cover for it is 84" x 84". That puts it in the Small. Master Spas notes that molded tubs can vary substantially from one to the next, so measure yours across the top both ways before ordering: about 83–85" takes the Small, and anything over 85" takes the Medium. If yours measures well under 83" or has angled corners, it is a different, older tub and this note does not apply to it.
Three Master Spas lines are sold under their own names, and their owners rarely think of themselves as Master Spas customers. Healthy Living (HL) had its own dealers and its own website, with owner’s manuals published through 2021; Legacy Whirlpool (LW) still sells today through legacywhirlpool.com; and the Contractor Series (CS) goes to builders and developers rather than to retail. All three are built by Master Spas on Master Spas shells — the CS Exeter is the Clarity Balance 7 cabinet, the CS Portsmouth the Balance 8, the CS Windsor the Precision 8 — so they take the same covers. The LW 7.2, LW 8.2 and LW 8.25 of Legacy Whirlpool’s Heritage Series share the footprints of the Twilight TS 7.2, TS 8.2 and TS 8.25. If the badge on your cabinet says HL, LW or CS, look for your model in the list above or in the notes below, which also name the models the AIRCAP 1™ does not fit. If yours is not named anywhere on this page, measure it across the top both ways before ordering.
Two naming quirks worth knowing before you order. First, the Legend models carry two names at once: the owner’s manual and the UL listing call them MPL 700, MPL 800 and MPL 850, while the website and your dealer call the same tubs LSX 700, LSX 800 and LSX 850. These are not different models and not different years — they are the same spa, and both names are listed above so either one finds you the right cover. Second, the Living Healthy 6 and Living Healthy 7 became the LH 6 and LH 7 for 2026, same spa and same listing number either side of the change.
Other names for tubs already in the list. The one-pump TS 6.1, TS 7.1, TS 7.15 and TS 8.1 are versions of the TS 6.2, TS 7.2, TS 7.25 and TS 8.2, printed at the same sizes: the TS 6.1 takes the XX-Small, the TS 7.1 and TS 7.15 the Small, and the TS 8.1 the X-Large. The HL 740L (also called the HL 740) is a one-pump HL 7, and the Balance 7 SE is a one-pump model of 2023 that Master Spas prints at the Balance 7’s 84" x 84"; both take the Small. The Legacy Whirlpool LW Enterprise SE and LW Inspire SE are trims of the LW Enterprise and LW Inspire and take the Small. Master Spas describes its Legacy Whirlpool VS spas as the Legacy line with plainer jets, lighting and insulation and no stereo, so a VS model takes the same size as the Legacy Whirlpool model of the same name.
Older Legend tubs: measure before you order. The LS 700, LS 800 and LS 850 were sold up to 2007, and Master Spas’ manuals print them at the same sizes as the LSX 700 (84") of 2008–2013 and the LSX 800 and LSX 850 (94") of 2008–2012. Master Spas’ 2014 manual prints taller LSX 700 and LSX 800 shells at the same sizes, so if yours is an LS 700, LS 800 or LS 850, or an LSX 700, LSX 800 or LSX 850 from before 2014, measure across the top both ways and check that the corners are not cut at an angle. If the two measurements are within an inch of each other, the longer one picks the size: 83–85" takes the Small and 92–94" the X-Large. The rectangular Legend models, such as the LS 650, are named further down.
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.
Some Master Spas models fall outside the range — almost all of them because the cabinet is rectangular, not square. The LSX 900 and Balance 9 run 108" x 94", the TS 67.25 is 70" x 84", the Ocho Rios CS and SE are 86" x 72", the San Miguel is 79" x 69", and the L5 is 78" x 60". More rectangular models, by line:
- Legend: the LS 650 (78" x 84"), the LSX 557 and LSI 557 (66" x 84"), and the LSX 1000 and LSX 1050 (94" x 120").
- Twilight: the TS 67.15 (70" x 84"), the TS MP (94" x 108"), and the TS Fit and TS Fit STS fitness spas (94" x 132").
- Clarity and Contractor Series: the CLS 415 and CS 415 (83" x 48"), the CLS 524 and CS 524C (66" x 84"), the CLS 1055 and CS 1055C (94" x 120"), the CLS Precision 67 and CS Acadia (84" x 70"), and the CS Nantucket (94" x 108").
- Healthy Living: the HL 616L, HL 624L and HL 628L (78" x 66").
- Legacy Whirlpool: the LW Envision (78" x 84"), the LW 524 (66" x 84"), the LW 715 (52" x 86"), and the Heritage LW 67.25 (70" x 84").
- Getaway: the Ocho Rios LE of 2017–2018, which the manuals of those years print at 71" x 87", like the Ocho Rios SE.
A few more look square on paper: the TS 240, TS 240X and TS 120 are all published as 78" × 78", but the factory drawings show a cut corner rather than a square cabinet, so a square cover will not sit on them. The TS 87.3 is listed at 94" × 94" in the 2016 manual and 94" × 84" in every year after it — the later figure is the right one and the spa is a rectangle. The CLS 360 is printed at 78" × 78", but we have not been able to confirm that the cabinet is square, so it is not in our list. Equal measurements alone do not prove a tub is square: a round top, or one with corners cut at an angle, measures the same both ways. 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″, Master Spas or not.
