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. With it, a traditional sauna can run conventional heat, infrared heat, or both at once.

The panels are made in Finland by Duetto, a specialist infrared manufacturer whose elements, according to Auroom’s brochure, 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, Auroom says, 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. Auroom’s brochure says the switch controls the panel through a 20-amp contactor with a 60-minute timer, so the panels shut off automatically when the timer runs out, and that the switch can be placed inside or outside the sauna.

Larger saunas can take several panels. Auroom’s brochure recommends one or two panels for small rooms and custom layouts for commercial or full-body installations.

It retrofits into rooms built as traditional saunas

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 makes every installed Auroom cabin a potential upgrade, alongside new buyers weighing one heat type against the other. Owners also don’t have to pick a side in the infrared-versus-traditional debate.

Aftermarket infrared panels have been available from various suppliers for years. The Duetto set differs in how far it is integrated. 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.

The panels are a Finnish brand sold under Auroom’s name

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.

Auroom’s brochure names the ESTONIA Resort Hotel & Spa as Duetto’s longest commercial reference, saying the panels have been running in its infrared sauna for more than seven years. That is a specific durability claim, in an industry where consumer trust in product claims is under scrutiny.

No North American model yet

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. If the retrofit kit eventually clears US certification, a dual-mode room would become a catalog order rather than a custom build.
