Auroom Adds Infrared to Its Sauna Line With Finnish-Made Retrofit Panels

Auroom Wellness, the Estonian cabin maker behind the Mira, Libera, and Aera sauna lines, has launched the Duetto Infrared Set: a wall-mounted panel system that adds infrared heat to any existing Auroom sauna. The product turns a traditional sauna into a dual-mode room capable of delivering conventional heat, infrared heat, or both at the same time.

The panels are made in Finland by Duetto, a specialist infrared manufacturer whose elements have been running in commercial settings for more than seven years. Auroom is now offering them as a factory-integrated option across its full lineup and as a retrofit kit for saunas already installed.

What the set includes

Each Duetto set ships with an infrared heating element, a wireless kinetic switch with fuse box and cabling, and a wooden cover grille. The panel itself is a black glass emitter rated at 900 watts, measuring roughly 36 by 12 inches. It surface-mounts horizontally or vertically on any wall. Two cover options are available: a slatted wooden grille that attaches with concealed magnets, and an ergonomic backrest with a decorative metal insert.

The wireless kinetic switch is the detail most likely to matter to installers. It generates its own power from the mechanical action of being pressed, which means no battery, no wiring to the switch location, and no external power source. The switch controls the panel through a 20-amp contactor with a 60-minute timer. When the timer runs out, the panels shut off automatically. Auroom says the switch can be placed inside or outside the sauna, depending on user preference.

Panels can be daisy-chained in series. For larger saunas, multiple panels on separate circuits can cover more wall area. The company recommends one or two panels for small rooms and custom layouts for commercial or full-body installations.

The retrofit angle

Most infrared saunas on the market are sold as complete cabins, built from the ground up with IR panels pre-installed. The Duetto set works in the other direction. It is designed to be added to saunas that were built as traditional rooms, without altering their core construction. Wiring routes behind the wall, through cladding, or along the surface. No structural changes are required.

That distinction changes the addressable market. Every installed Auroom cabin becomes a potential upgrade candidate, not just new buyers weighing one heat type against the other. It also sidesteps the infrared-versus-traditional debate entirely: owners do not have to choose. The Duetto concept assumes most people will want both.

Aftermarket infrared panels have been available from various suppliers for years. What makes the Duetto set different is the integration depth. Auroom has built it into its product configurator across the Mira L, Libera, and Aera lines, meaning new buyers can order a factory-configured dual sauna rather than retrofitting one later. The IR panels share the same wood palette (aspen, alder, thermo-treated alder) as the cabins themselves.

A Finnish brand inside an Estonian line

The infrared elements carry the Duetto name, and the brand has its own presence in the Finnish market. Finnish retailers like Saunastore.fi and Finnsauna.fi list Duetto as a separate manufacturer, with product pages dating back several years. Finnish fitness clubs already use Duetto panels in commercial installations.

Auroom, based in Vana-Kastre, Estonia, and led by CEO Marten Merdikes, is folding Duetto into its own product range rather than simply reselling the panels. The brochure carries the Auroom brand throughout, and the panels are marketed as part of the Auroom accessory catalog. The company already sources its timber from Thermory, the Estonian wood treatment company, so cross-border supply chain relationships are familiar territory.

Duetto’s longest commercial reference is the ESTONIA Resort Hotel & Spa, where the panels have been running in the infrared sauna for more than seven years. That is a concrete durability claim in an industry where consumer trust in product claims is increasingly scrutinized.

The North American question

Every product specification in the brochure lists only the EU model at 230 volts and 900 watts. No 120-volt model, no North American voltage variant, and no UL listing number appear anywhere in the documentation. Auroom’s brochure describes the US elements as “UL-equivalent”; SaunaNews could not find a UL or other NRTL listing for them, which US inspectors generally require. The distinction matters for inspectors, insurers, and anyone specifying equipment for a commercial project.

Until Auroom publishes a North American product sheet with a specific voltage, NRTL listing, and distribution channel, the safe assumption is that the Duetto set is a European product. North American operators and dealers who want to explore it will need to confirm the electrical and certification path on their own.

Correction, September 25, 2026: an earlier version of this article said the panels can be daisy-chained in series up to 450 watts per circuit, less than the draw of a single panel. Each Duetto element is rated at 900 watts, per Northsauna’s Auroom Duetto listing; the per-circuit limit could not be confirmed and has been removed.
