Icelandic Hot Tubs Replacement Hot Tub Covers

What size AIRCAP 1™ fits your Icelandic hot tub?

Icelandic Hot Tubs, which now calls itself Icelandic Wellness, is a brand of GPM Manufacturing of Franklin, Kentucky — the company that also owns Harmonic, Celtic and Resort Hot Tubs. Its hot tubs, swim spas and cold plunges are sold through dealers, and its website is still icelandichottubs.com. Our fitter lists four of its hot tubs with square cabinets that an AIRCAP 1™ fits. All four are recent — the Fjord and Oasis arrived in 2025 and the Fontana and Soluna in 2026 — so there is no older tub of the same name to tell apart, and none of them shares a shell with a Harmonic, Celtic or Resort model.

Here is how the 4 Icelandic models in our fitter map to AIRCAP 1™ sizes:

• The Fjord, Fontana and Soluna each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The Oasis takes the AIRCAP 1™ Large, which fits square spas 89–91".

The Fjord, Fontana and Soluna are the same size. Icelandic prints all three at 85" x 85", so all three take the Small; what differs is the seating moulded into each shell — the Fjord has five seats and a lounger, the Soluna three seats and two loungers, and the Fontana seven seats around a round footwell. The Soluna is a special-order model: it appears in Icelandic’s 2026 brochure but not on its website.

Fontana owners: check which tub you have. The Fontana’s deck is styled like the larger 91" Oasis, and some of Icelandic’s own top-view pictures of the Fontana actually show the Oasis shell, so do not choose a size from a picture. Measure across the top before you order: about 85" means the Small, about 91" the Large.

Cascade owners: measure before you order. Icelandic added the Cascade in 2026 and lists it at 91" x 91", but the only top-view picture it publishes for it shows the 85" Fjord shell, so we have not been able to confirm its size or shape, and it is not in our fitter. Measure your cabinet across the top in both directions, or ask your dealer or Icelandic for the cabinet size, and use the SureFit™ measuring guide to pick the AIRCAP 1™ size that matches.

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 Icelandic tub takes a square cover. The Cyclone 3 and the earlier Cyclone 1 are listed at 93" x 93", but they are round tubs and those figures are their diameter. The Aurora (82" x 72"), Fire & Ice (91" x 85", a split hot-and-cold tub) and Icelandic Fire (85" x 41") are rectangles; the Fossa, Triathlon and Icelandic Swim are swim spas, far longer than any hot tub; and the Icelandic Bath, Icelandic Plunge and Icelandic Air are cold plunges. 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 hot tub, Icelandic or not.
