Saunum Drops the Air 10 in North America. The Air L Fills the Gap.

Saunum has removed the Air 10 from its North American lineup. The company’s US product page now lists the Air heater in 5kW and 7kW only, both available in stainless steel and black with a closed basket. For rooms that once called for the 10kW model, Saunum is directing buyers to the Air L, a higher-capacity line that starts at 10kW and keeps its rock basket about nine inches lower than the discontinued unit.

The change simplifies Saunum’s residential lineup, but it also moves large-room buyers into a heater that is, by at least one important measure, a better match for the company’s signature technology.

What changed in Saunum’s North American lineup?

The Saunum Air product page now shows two heater sizes. The 5kW model covers rooms from 106 to 212 cubic feet. The 7kW covers 177 to 282 cubic feet. Both come in stainless steel and black, with the closed basket configuration that keeps stones fully enclosed.

The Air 10, which served rooms from 247 to 424 cubic feet, is no longer listed. That leaves a gap in the residential lineup for builders and homeowners designing larger saunas.

The Air L puts the rocks where they belong

Saunum’s answer for that range is the Air L, a heater built for commercial and large residential applications. The Air L 10kW covers 283 to 494 cubic feet, overlapping most of the discontinued Air 10’s range and extending well beyond it. The 13kW and 15.2kW models push capacity to 741 cubic feet, serving commercial-scale rooms, spas, and high-volume installations where durability and stone mass matter.

The Air L also brings one structural change that matters for how Saunum heaters actually work. The top of the rock basket sits at 33 inches, compared to 42 inches on the old Air 10. That nine-inch difference is significant for Saunum’s air-blending system.

How does Saunum’s air blending work?

Every Saunum heater uses a built-in blending module that draws superheated air from the ceiling and mixes it with cooler air near the floor. By Saunum’s figures, a conventional electric heater can produce a ceiling-to-floor temperature differential of roughly 146°F, and Saunum’s system compresses that gap to around 47°F. The result is heat that feels even from head to toe, rather than scorching near the ceiling and tepid at the ankles.

A lower rock basket positions the heating elements and blending module closer to where bathers actually sit. For a heater that works by moving air, that geometry is a real performance gain.

What does the full package cost?

Saunum sells complete packages that include the heater, the Leil controller, sauna stones, and shipping from its Chicago warehouse. The Air 5kW package starts around $2,895 and the 7kW around $2,995. The Air L 10kW package starts near $6,900, with the 13kW and 15.2kW running higher.

That price gap is the main consideration for former Air 10 buyers. The Air 10 package sat in the $3,000 to $3,500 range. Moving to the Air L roughly doubles the cost. But the Air L is also a more commercial-grade product: heavier build, 265 pounds of stone capacity (versus the Air’s smaller load), and designed for the kind of repeated use that wears out residential-grade heaters in high-traffic applications.

The Air L also requires more floor support planning and a longer initial heat-up time given the larger stone mass. On the electrical side, both lines run 240V single-phase, so wiring requirements stay consistent.

Where the Air Perfect and Leil fit in

The Air and Air L are not the only options in Saunum’s North American catalog. The company recently launched the Air Perfect, a self-contained model that handles air equalization entirely inside the heater body rather than through an external chimney-style flue. The Air Perfect is available at 7kW ($4,770) and 10kW ($4,970), positioning it between the Air and Air L on price while offering the simplest installation path of any Saunum heater. For builders who want Saunum’s technology without routing a flue to the ceiling, the Air Perfect is the most straightforward option in the lineup.

Saunum has also continued refining its Leil climate control system with software updates for better temperature automation, fan management, and a smoother in-session user experience. Recent changes across the product line have focused on reducing installation friction and simplifying the setup process for electricians and builders working with Saunum for the first time.

US mode and UL listing

All Saunum heaters sold in North America are UL-listed and ship in US mode, capped at 194°F. In European markets, the same heaters run up to 212°F.

The SaunaLife G6: Saunum in a turnkey cabin

Buyers looking for a complete sauna rather than a standalone heater have one more path to Saunum’s technology: the company sells its Classic cabin in North America through a partnership with SaunaLife, marketed as the SaunaLife G6. The G6 is a fully assembled outdoor sauna for five to six people, built with alder and spruce in Northern Europe and priced in the $25,000 to $27,000 range. It pairs Saunum’s air-blending heater with a turnkey enclosure.

Prebuilt cabin saunas like the G6 are gaining traction for rooftop terraces at hotels, commercial wellness facilities, and residential properties. A factory-assembled unit typically needs to be craned or forklifted into position, but the tradeoff is build quality: joints, vapor barriers, and interior finishing are done under controlled factory conditions rather than on a job site. For operators adding a sauna to a rooftop or upper-floor amenity deck, a prebuilt cabin paired with Saunum’s climate system is one of the fastest paths from purchase order to open sessions.

Correction, September 25, 2026: an earlier version of this article put the top of the Air L’s rock basket at 34 inches, eight inches below the Air 10’s, and said the Air L 10kW covers 247 to 494 cubic feet. The basket top is 33 inches (840 mm), about nine inches below the Air 10’s, and the 10kW model is rated for 283 to 494 cubic feet, per Saunum’s US Air L installation manual.
