Pinnacle Spas Replacement Hot Tub Covers

Pinnacle sells direct, online only, and its current range splits into collections — Essence, Pulse, Elevate and Ascend. Eleven of its seventeen named models take an AIRCAP 1™, spread across five sizes. Most Pinnacles sold before this range carry model codes instead of names, and thirteen of those older tubs are in our fitter too.

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

• The LX 5000 (DX 5000) takes the AIRCAP 1™ XX-Small, which fits square spas 77–79".
• The Wave, Alterra, Radiance and Valaris each take the AIRCAP 1™ X-Small, which fits square spas 80–82".
• The Regal, Majestic, PN 740 (Pinnacle Plus), PN 741 (Pinnacle Plus), PN 743 (Pinnacle Plus), PP755 (Pinnacle Plus), LX 9000 (Luxury Series), LX 8000 (Luxury Series) and PR761 (Pinnacle Premium) each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Cascade (2026 and later) takes the AIRCAP 1™ Medium, which fits square spas 86–88".
• The Highpoint, Summit (2026 and later), PN 850 (Pinnacle Plus), PN 855 (Pinnacle Plus), PP851 (Pinnacle Plus), PS850 (Pinnacle Standard) and PR881 (Pinnacle Premium) each take the AIRCAP 1™ Large, which fits square spas 89–91".
• The Crest and Transcend each take the AIRCAP 1™ X-Large, which fits square spas 92–94".

Majestic owners: you will measure two different numbers, and that is correct. The Majestic is the one Pinnacle cabinet that is not quite square — its own spec sheet prints 84" x 83.5". Measure it one way and you get 84", turn ninety degrees and you get 83.5". Nothing is wrong with your tub or your tape. Both figures fall inside the Small range, so the Majestic takes the Small either way, and the half inch disappears under the cover’s overhang.

Several Pinnacle cabinets are shells you will already find elsewhere in this fitter. The Crest matches the two-pump Catalina Berkshire seat for seat and jet for jet; the Transcend prints the same 93.5" square as the Catalina Nantucket; the Highpoint the same 91" square as today’s Dr. Wellness G-11, and the Summit the same as today’s G-12; the Regal the same 83.5" as the Catalina Carlton; the Majestic the same 84" x 83.5" as the Catalina Hampton, asymmetry and all; and the Radiance and Valaris the same 82" square as the Dr. Wellness G-6 (2025 and later). Each of those Pinnacle models takes the same AIRCAP 1™ size as its twin. The Alterra prints the same 82" footprint as the Radiance and Valaris, but on a lower 34" cabinet with a different seat and jet count, so it is a different tub — with the same answer, the X-Small.

Crest owners: measure across the top. Pinnacle prints the Crest at 93.5", but the factory sheets for the same Catalina Berkshire shell print it at 92" to 92.5", and Catalina’s own product description at 91". If yours measures 91" or less, take the Large (89–91"); otherwise take the X-Large — between sizes, always round up.

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. That matters more than usual on Pinnacle’s tubs, whose cabinet heights run from 34" to 40".

Older Pinnacles: go by the model code. Before the current range, Pinnacle mostly sold its hot tubs under letter-and-number codes rather than names — first the Pinnacle Plus (PN) and Luxury Series (LX) tubs, later the Pinnacle Standard (PS), Pinnacle Plus (PP) and Pinnacle Premium (PR) tubs. A three-digit code after PN, PS, PP or PR, or an LX or DX code in the thousands, such as LX 9000 (the two-digit LX 74 is a Premium Leisure Mark III tub), means one of these older tubs, not a model from today’s named range, even where the size is the same. Pinnacle used the Pinnacle Plus name twice, for the PN tubs and again for the PP tubs, so check the code rather than the series name. Two-digit codes are different: the PP53 on Pinnacle’s current site is not an older Pinnacle Plus, and the PP53 spec sheet prints the same 87" square and 53 jets as today’s Cascade. And if Pinnacle is the model name on your tub rather than the brand, it may be the Aspen Spas Pinnacle, which is listed under Aspen.

Pinnacle’s owner’s manual prints the PN 850 and PN 855 at 91" square, the PN 740, PN 741, PN 743, LX 8000 and LX 9000 at 84" square, and the LX 5000 at 79" square — the DX 5000 is the same tub without the air jets. The LX 9000 has the same 7-seat layout around an octagonal footwell, and the same 84" square, as one of Premium Leisure’s Health’n Leisure tubs, so it shares that tub’s photo here. We list the LX 8000 without a photo, because the only top view of it we have found is too small to use.

Pinnacle’s pages for the later PS, PP and PR tubs are no longer online, so for those we go by what survives. The PS850, PP851, PR761 and PR881 are the same shells as the Premium Leisure GO 850, LE 851, PR 761 and PR 881 in this fitter — their top-view photos match — so each takes the same size as its twin. The PS850, PR761 and PR881 share their twin’s photo; the PP851 has a photo of its own. The PP755 is printed at 84" square in dealers’ copies of Pinnacle’s spec pages, and its top-view photo shows a square shell. It matches, seat for seat and jet for jet, the FH 755 that Premium Leisure’s Fourteen Hundred Spas manual prints at 84" square.

Measure these older Pinnacles before ordering. The PS742 is square, but it is printed at 84" in dealers’ copies of Pinnacle’s page and at 82" for the same shell elsewhere — the difference between the Small and the X-Small — so measure yours: 80–82" takes the X-Small and 83–85" the Small. The PP864 is printed at 91" square, but we have not been able to confirm its shape. The PP740 may be the PN 740 sold again, but we have not confirmed that. We have found no printed size for the PS746, PS852, PP752, PP857 or PN 851. Premium Leisure’s Fourteen Hundred Spas manual prints tubs with the same numbers — the FH 864 and FH 857 at 91" square and the FH 752 at 84" square — but we have not confirmed they are the same tubs as the PP864, PP857 and PP752, so measure before ordering. Pinnacle’s 2008 owner’s manual also lists named tubs — the Eminence, Olympia, Venus, Everest, Meridian, Horizon, Summit, Cascade and Solstice — and we have no sizes for any of them. If you own an older Pinnacle Summit, Cascade or Solstice, it may not match today’s model of that name, so measure it. The LX 11000 is printed at 96" square in Pinnacle’s manuals, larger than the X-Large’s 94" limit. It has the same layout as Premium Leisure’s HL 860, which Premium Leisure prints at 94", so measure yours: 92–94" across the top takes the X-Large, and if it is larger, no AIRCAP 1™ size will fit.

Models the AIRCAP 1™ does not fit. The Haven is a true square at 76" x 76", but that is one inch below our 77" minimum, so no AIRCAP 1™ size will fit it — please do not order the XX-Small for a Haven. The Tempo and Vale (82" x 63"), the Diamond (82" x 69.5"), the Solstice (60" x 70") and the Pure (35.75" x 79.5", a one-person soaker) are all rectangular. Pinnacle’s swim spas — the Malibu, the Marathon and the Freestyle — are far outside a square cover’s range. Among the older tubs, the PN 631 (84" x 78"), LX 4000 (86" x 58") and PS634 (84" x 72") are rectangles, and the older corner spas are not square either. We could not confirm a printed size for the other PS tubs numbered in the 600s, such as the PS612, PS620 and PS633, and nothing we found suggests any of them is square, so measure one before ordering. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.

Dimensions for the current range are as printed on each model’s own 2026 Pinnacle spec sheet, checked against the factory sheet for the same shell where one is published (they agree for every model except the Crest, explained above); for the older PN and LX tubs they come from Pinnacle’s owner’s manual, and for the PS, PP and PR tubs from the sources above. Cabinet sizes can change between model years, so measure your spa side to side across the top of the cabinet before ordering; the SureFit™ measuring guide walks through it in two measurements. If your measurement falls between two sizes, round up.
