Assessment: the full-spectrum powerhouse for the corner of the room
The Artsauna Kiruna90 belongs to the smallest cabin class on the market: a 90 x 90 centimetre footprint, intended for exactly one person. Even so, it does not come as a cut-price version technically, but combines a full-spectrum front with panel heaters behind the back. It was precisely this mix that put it at the top of our comparison of the best full-spectrum infrared cabins; this data check takes a closer look at the cabin on its own.
For us, a data check is not a laboratory measurement: we gather the documented manufacturer and retailer information, compare it with documented user experiences and assign an editorial rating on that basis. Whether the mild radiant heat of an infrared cabin suits you at all, or whether you want the classic sauna climate, is answered before purchase by the fundamentals article Infrared cabin or sauna.

A note on the footprint: 90 x 90 centimetres sounds like nothing, but still needs planning. Allow a few centimetres of clearance from the wall for rear ventilation, plan for the swing area of the glass door and remember a socket within reach that is not already taken by other continuous loads. Cabins of this type are usually delivered in flat packs with prefabricated elements; they fit through normal room doors without any problem, and assembly takes place directly at the installation spot. For the assembly itself, it is best to plan for two people and a free afternoon.
Strengths in everyday use
The Kiruna90 solves the most common dilemma of single cabins: full-spectrum or panel warmth? It answers with both. Four full-spectrum heaters in the front deliver quick, intense direct heat, while three panel heaters lay a mild base warmth over the back and calves. Anyone who likes both kinds of warmth or simply does not want to commit gets the most pragmatic solution of the compact class here, and the LED colour light together with the full-glass door create a wellness feel rather than a boxy look.
In everyday use, the format also counts: 90 x 90 centimetres fit into almost any free corner, from the bedroom to the study. Running from a normal 230-volt socket makes an electrician unnecessary, and the small cabin volume reaches operating temperature quickly. Running costs also stay manageable, since a single cabin is one of the most economical ways to sweat regularly; you can find the concrete example calculations in the article on the power consumption of a sauna and infrared cabin.
And because a single cabin answers to no one, it adapts to your own rhythm: a short session in the morning, a longer one with colour light in the evening, with no need to coordinate with the rest of the household. Many buyers report that it is precisely this frictionlessness that makes the difference between a cabin still being used after the first winter and ending up as an expensive towel rack. What regular heat sessions can mean for relaxation and wellbeing, and where the honest limits lie, is assessed in our article Is sauna healthy?.
Honest limits
The most important limit is already in the name: the Kiruna90 is a cabin for one person, and good will does not change that. The bench is designed for solo use; anyone who wants to sweat regularly as a pair needs the two-person class from 115 centimetres in width. The product information does not list multimedia features such as Bluetooth or radio, so relaxation music has to come from your own speaker placed in front of it.
And the system question applies here too: the full-spectrum front works with intense, reddish direct heat that not everyone likes. Artsauna addresses this with a premium variant of the Kiruna90 whose back heater can be dimmed steplessly; anyone who values finer dosing will find it categorised right next to the base version in our full-spectrum comparison. Even the best infrared cabin, however, does not replace a classic 90-degree sauna climate with infusions.
Who it is worth it for, and the alternatives
The Kiruna90 is worth it for anyone who uses a sauna alone and wants maximum heating technology on minimal floor space: singles, home-office sweaters and everyone whose home has no room for a two-person cabin. It is not a compromise downwards but the consistently thought-out single cabin, and in the field of single cabins from our infrared cabin buying guide the most complete package.
Two alternatives for other situations: anyone who does occasionally sweat as a pair takes the Artsauna Oslo at 120 x 100 centimetres with full-spectrum equipment. And anyone who would rather regulate the warmth on their back steplessly goes for the already mentioned Kiruna90 Premium with a dimmable back heater, which we list in the comparison of full-spectrum cabins as a comfort upgrade.
The decision logic in brief: if the cabin stands in a room you use alone, and every centimetre counts, there is currently hardly a reason to look past the Kiruna90. If it is foreseeable that your partner will want to sweat along, invest the extra cost in the two-person class, because a cabin that is too small tends to become a bone of contention. And if you are torn between both worlds, it is best simply to measure the available space; often the home answers the question by itself.
Verdict: editorial rating 4.4 out of 5
That leaves the question of how long the verdict will hold: the Kiruna90 is no flash in the pan but has been on the market for several seasons, with a correspondingly broad base of documented user experiences that support our picture drawn from the manufacturer information. Four full-spectrum and three panel heaters, colour light, glass door, socket operation: the Kiruna90 packs a surprising amount of heating technology into 0.81 square metres of floor space and stays in the entry-level price class while doing so. You need to know that it is tailored uncompromisingly to one person; then it will not disappoint. That earns it the editorial rating 4.4 out of 5; how our ratings come about is explained on the page about our editorial team.
