Hot Spring Spas Replacement Hot Tub Covers

Hot Spring Spas spans the Highlife, Limelight, Hot Spot and Freeflow collections, and seventeen models fall inside the AIRCAP 1™ range. The Freeflow Monterey and Excursion, at 78" square, are the most compact tubs we fit; the Beam, Bolt and Pace come next; the Flash, Flair, Rhythm and Relay, and the older Hot Spot Mallorca, sit just above them; the Vanguard and Aria, and the NXT-badged versions of both, are larger again; the Pulse and Tempo come after those; and the older Hot Spot La Palma, at 91" square, is the largest we fit.

Here is how the 17 Hot Spring Spas models in our fitter map to AIRCAP 1™ sizes:

• The Monterey and Excursion each take the AIRCAP 1™ XX-Small, which fits square spas 77–79".
• The Beam, Bolt and Pace each take the AIRCAP 1™ X-Small, which fits square spas 80–82".
• The Flash, Flair, Rhythm, Relay and Mallorca each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Vanguard, Aria, Vanguard NXT and Aria NXT each take the AIRCAP 1™ Medium, which fits square spas 86–88".
• The Pulse, Tempo and La Palma each take the AIRCAP 1™ Large, which fits square spas 89–91".

Aria NXT and Vanguard NXT owners: your spa is the same cabinet as the Aria and Vanguard above. Watkins sold the NXT versions alongside the plain models in 2017–2019, then dropped the NXT badge while keeping the same shells and the same factory model codes — the 2019 Highlife NXT manual prints “ARIA NXT (Model ARN)” and the current manual prints “ARIA (Model ARN)”, both at 87" square. Both are listed here so that whichever name is on your paperwork, you land on the right cover.

Hot Spot Mallorca and La Palma owners: both are retired Hot Spot models, sized here from the Hot Spot owner’s manuals that Hot Spring still publishes. Every Hot Spot manual from 2003 to 2008 prints the Mallorca (Model MAL) at 84" square — the same footprint as the Relay and Rhythm, so it takes the same Small cover. The La Palma (Model LAP) first appears in the 2008 manual, at 91" × 91", and Watkins’ own Hot Spot website printed it at 7′7" × 7′7" the same year; it is gone from the 2010 manual. It is not the Tempo: the La Palma is a larger, seven-seat tub. The overhead photos in the 2008 manual show both as square shells with rounded corners. At 91", the La Palma is at the top of the Large range, so measure it across the top of the cabinet before ordering — if yours measures over 91", take 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 Hot Spring tub takes an AIRCAP 1™. The Grandee, Envoy, Vista, Landmark, Gleam and Prism are rectangular — and the Gleam and Prism, at 110" wide, are beyond our range entirely. The Sovereign (80" x 93"), Prodigy (84" x 78") and Accolade (78" x 87") are near-misses: both sides land inside our band, but none of them is square. The 2003 Highlife (Model ILE) is the same near-miss: it was the Sovereign Limited Edition sold under the Highlife name, at the same 80" x 93". The Jetsetter and Jetsetter LX share a rectangular shell whose 68" depth is too small, and the Stride, SX, Azure, Mini, Glow and Triumph are also rectangular and undersized, as are the Hot Spot Trinidad and the Hot Spot Tobago (both 80" x 70"). The TX is square but at 72" sits under our smallest size. Watkins printed the Hot Spot SE and SLX at 78" square, but the SLX's 285-gallon shell was also sold in a redwood cabinet as the 71" SLXtra, and replacement covers for the SE and SLX are sold at 72" square — below our 77" minimum. The Aptos and the Hot Spot RE, RLX, Sprint and Dash are round (the Hot Spot rounds are 78" across), so a square cover cannot fit them. Two older tubs have square-looking sizes but are not square cabinets. The Classic (Model F, sold until 2000) is printed at 7′6" x 7′7", but its sides bow outward and its corners are very large and rounded. The Hot Spot Sorrento (2003–2009) is printed at 78" square, but one corner is cut off on a diagonal that starts about 23" from the corner on each side. The Vigor is a cold plunge, not a hot tub. 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″, Hot Spring Spas or not.

Freeflow Monterey and Excursion owners: the sizes above are for the 2026 models, which Watkins redesigned as 78" × 78" squares (the 5-seat Monterey and 4-seat Excursion). The earlier 7-seat Monterey (about 88" × 78") and 5-seat Excursion (about 86" × 77") are rectangles, and no square cover fits them — if your spa seats seven or has a long side, measure it before ordering.
