Wellis Spas Replacement Hot Tub Covers

Wellis Spas names its hot tubs after cities and mountains, and twenty-seven models fit an AIRCAP 1™ across five sizes. The Prague is the most compact, and the Everest, Elbrus Life and Kilimanjaro Life are the largest.

Here is how the 27 Wellis Spas models in our fitter map to AIRCAP 1™ sizes:

• The Prague takes the AIRCAP 1™ XX-Small, which fits square spas 77–79".
• The Mercury, Hercules, Atlas, Mandala, Hercules PRO, Makalu Life and Venus each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Houston, Malaga (Cordoba), Rental Escape (Valencia), Lima, London, Paris, Milan (Palermo) and Monte Bianco (Discovery) each take the AIRCAP 1™ Medium, which fits square spas 86–88".
• The Mont Blanc, Monte Rosa, Vienna, Lugano, Taurus, Libra, Elbrus 230 and Saturn each take the AIRCAP 1™ Large, which fits square spas 89–91".
• The Everest, Elbrus Life and Kilimanjaro Life each take the AIRCAP 1™ X-Large, which fits square spas 92–94".

The Hercules PRO measures 85 inches square — the same footprint as the standard Hercules — so both models wear the same AIRCAP 1™ Small cover.

The Houston sits right at the line between the Small and the Medium. Wellis prints it as 85" in its product page’s specification table and as 86" in the description on the same page. Bueno Spa sold the same tub, part number WM00863, as the Moreno, and overhead photographs and published weights match it to the Bueno Chicago, whose factory drawing says 2170 mm, or 85.4". That rounds up to the AIRCAP 1™ Medium, the size the Chicago takes. Measure across the top before you order: if yours measures 85" or less, take the AIRCAP 1™ Small.

Wellis owners: check the full name on your cabinet, not just the mountain. Wellis has re-used two of its names across different sized shells, and in one case sold two of them at once. Its own October 2020 European brochure prints a CityLine Elbrus at 2180 mm and a PeakLine Elbrus 230 at 2300 mm on facing pages, and today’s Elbrus Life is larger again at 93". Three sizes, one mountain. Kilimanjaro is the same story: the current Kilimanjaro Life is 93", while the PeakLine Kilimanjaro was 2300 mm and the MyLine Kilimanjaro Standard is the spa sold in the United States as the Taurus. We list each under its full printed name so none of them is a trap — but if your paperwork says only “Elbrus” or “Kilimanjaro”, measure across the top of the cabinet before ordering rather than assuming the current model. Wellis’s US manual also lists other Malaga and Palermo shell codes, one of each with no year on it and one of each marked 2020, that we have not been able to size, so measure a Malaga or Palermo before ordering as well.

A note on units. Wellis specifies in millimetres in Europe and in inches in the United States, and the two agree once converted: 2300 mm is 90.55", which Wellis itself prints as 91" on its US pages, and 2130 mm is 83.86", which it prints as 84". The figures above are in inches throughout, so they match what your tape measure will read. The Milan and the Monte Bianco are the exceptions: Wellis’s drawings give them only in millimetres, so we have converted their 2180 mm the same way, to 85.8", which rounds up to 86" — the figure Wellis prints for the 2180 mm Malaga. Most Wellis sizes sit at the edge of a band, so measure across the top before ordering: an 86" model, the Milan and Monte Bianco included, that measures 85" or less takes the AIRCAP 1™ Small; an 85" model that measures over 85" takes the Medium; a 91" model over 91" takes the X-Large; and a Prague over 79" takes the X-Small.

Wellis also sells one spa under two names depending on the market, and the US name is not always the one in the paperwork. Wellis’s own US manual, and the March 2020 drawings in it, print the European shell name beside most of the US hot tub names they list, so these pairs come from the factory. The London is the European Malaga; both are listed above and both take the same Medium cover. The Milan is the 2018 Palermo and the Monte Bianco the European Discovery, and both take the Medium too. The Paris is the CityLine Elbrus of 2018 — a different and smaller spa than either the Elbrus 230 or the Elbrus Life, so there are three distinct Elbruses in this list and only the Paris takes the Medium. The Mont Blanc is the Elbrus 230 under its US name, and the US manual heads the Libra’s drawing “Libra (Elbrus 230)” as well; all three are 2300 mm and take the Large. The Monte Rosa and the Taurus are both drawn as Kilimanjaros at 2300 mm and take the Large; the Taurus is the European Kilimanjaro Standard, which is not the Kilimanjaro Life either, and its part number, WM00717, is the one Wellis’s US factory store now uses for the Lugano Life. If the name on your paperwork is not in the list above, it may be here under its other market name.

The Monte Bianco and the Milan are retired US models, and each has a near-namesake that is a different spa. The Monte Bianco (Discovery) is not the Mont Blanc, although Monte Bianco is Italian for Mont Blanc. The Monte Bianco is the smaller spa, 2180 mm with rounded corners, a W-logo console in the middle of one side and a ribbed bench down the centre, and it takes the Medium; the Mont Blanc is 91" with a round centre footwell and takes the Large. The Milan (Palermo) is not the Milano either: the Milan is a square 2180 mm spa with cut corners, sold in the United States from about 2018, while today’s Milano P&P and Milano PRO are 85" × 75" rectangles that no square cover fits.

Some of Wellis’s European holiday-let tubs are listed here with the spa they match. The Valencia matches the Rental Escape feature for feature in Wellis’s overhead pictures — the diamond-shaped footwell, the skimmer in the middle of one side and the four corner seats — and Wellis prints it at 218 × 218 cm against the Rental Escape’s 86", so the two share a row and take the Medium. Strong Spas’ MyHotTub store sells an unrelated 85" Valencia, which takes the Small; the Valencia listed here is the Wellis holiday-let tub only. The Cordoba matches the Malaga the same way, cut corners included, and is also 218 × 218 cm, so it shares the Malaga’s row and its Medium.

Wellis also builds the Bueno Spa range, and several Bueno tubs match a Wellis. Besides the Houston, which Bueno sold as the Moreno, the Rental Escape is the tub Bueno sells as the Vacation, and the Monte Bianco is laid out like the Bueno Hollywood: the seats, footwell and console line up feature for feature, though the part numbers differ and Bueno’s drawing of the Hollywood says 2200 mm against the Monte Bianco’s 2180. Each of these pairs takes the Medium. The Hercules, part number WM00713, is the tub Bueno sold as the limited-run Vista, and both take the Small. The Avatar Cinema from Wellis’s WibeSpa range (part number WM00858) is the tub Bueno sells as the Denver — Bueno prints that part number on its Denver listing — so it takes the Denver’s Medium; Wellis uses the Cinema name on smaller tubs too, so look for Avatar or WM00858 before you order. All of these are on our Bueno Spa page.

Some Wellis shells have angled corners rather than rounded ones, and it is worth knowing before you order. The Prague, Malaga, Lima, London, Paris and Milan are built on Wellis's CityLife mold, which takes about six inches off each corner at 45 degrees instead of rounding it. The footprint is still square and the size listed above is the size to order — a Prague measures 79" across, a Malaga 86". What differs is the corner itself: a square AIRCAP 1™ runs along all four sides and then carries straight across each angled face, standing proud of it by roughly four inches on the diagonal. Wellis cuts its own covers for this mold to match that angle, so a factory replacement is shaped differently from a square one. Every other Wellis in the list above has ordinary rounded corners.

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 Wellis Spas model takes an AIRCAP 1™. The Teide Life, Milano, Oslo, Manhattan Life and Olympus Life are rectangular rather than square, and so were their earlier US versions: the Leo P&P, an earlier name for the Milano P&P; the Orion P&P, an earlier name for the Oslo P&P; and the Rome, which the US manual lists as the 2018 Manhattan. The Marbella is rectangular and under the 77" minimum besides, and so was the Berlin, the US name for the 2018 Marbella. Older European models are out too: the Acapulco and Earth are round, and the Sun Family is square but only about 75" across. The Iceland cold-plunge models and the Beach Club swimming pools are a different kind of product, and the Rio Grande, Amazon, Danube and Elba are swim spas far outside cover range. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.

Wellis’s European range also includes square models we do not list, such as the Jupiter, Pluto and Budapest Life. Whichever Wellis you own, measure it 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″, Wellis Spas or not.
