Quick Answer: Auroom is a premium Estonian sauna manufacturer, part of the Thermory Group (the world’s largest thermally-modified-wood producer), known for a signature full tempered-glass front wall across its Cala, Mira, and Libera lines. Pricing runs roughly $7,590 to $18,800 for indoor cabins and $14,990 to $58,900+ for outdoor models — but per Harvia’s own package pricing, that figure doesn’t include the heater, which is sold separately and typically adds $1,846 to $4,279 depending on cabin size, on top of the 240V electrical work nearly every model needs. Budget for the full stack, not just the sticker price.
Auroom shows up in a lot of “best outdoor sauna” roundups for its glass-walled look, but most of those guides quote the cabin price and stop there. Here’s the full lineup, and the add-on cost that changes the real math.

1. Cala Glass Mini — the cheapest way in
Auroom Cala Glass Mini Indoor Sauna
- The entry point into Auroom's signature look — a full tempered-glass front wall in a footprint small enough for a bathroom or finished basement corner.
- Pairs with a Harvia KIP 4.5kW heater package, which runs an additional $1,846-$2,047 and isn't included in the $7,590 figure.
- Still needs the dedicated 240V circuit covered in our sauna installation cost guide — budget $500-$1,500 more for an indoor electrician run.

2. Aura — the entry-level outdoor glass cabin
Auroom Aura Outdoor Cabin Sauna
- Brings the same full-glass front wall outdoors, in a standalone cabin shape rather than the barrel format most outdoor sauna brands default to.
- A cabin this size typically pairs with a Harvia Virta package in the $3,495-$4,279 range, not a cheaper KIP unit — confirm which heater tier a dealer quote actually includes before comparing prices across retailers.
- Outdoor installs generally run higher electrical costs than indoor ones — see our installation cost guide for the $1,500-$3,800+ range once trenching and conduit are involved.
3. Arti — the flagship, and where the heater gap is clearest
Auroom Arti Outdoor Flagship Sauna
- Some dealer listings quote $38,990 for the bare cabin kit; others quote roughly $42,780 for the same cabin bundled with a Harvia Club heater package and digital controller — a roughly $3,790 gap that's effectively the heater's real price, made visible for once.
- Largest standard-capacity outdoor model in the current lineup below the Natura Outdoor Lounge tier (which runs $58,900+).
- Compare against our best outdoor sauna guide if you want flagship-size capacity without the glass-wall premium.
The heater gap most reviews don’t mention
Auroom cabins are sold as structure-only kits — walls, bench, glass front, door — with the heater priced and purchased as a separate line item, almost always a Harvia package since Auroom doesn’t manufacture its own heaters. Per current Harvia retailer listings, a compact indoor cabin typically needs a KIP 4.5kW package running $1,846-$2,047, while a larger outdoor cabin needs a Virta 10.5kW package at $3,495-$4,279. That’s not a hidden fee exactly — Auroom’s own retail partners generally disclose it if you read the full product page — but it’s easy to miss when a price comparison only lists the cabin-kit number, which is the figure most “Auroom sauna price” roundups quote on its own.
Stack that on top of the electrical work nearly every model needs. Our sauna installation cost guide breaks down why larger cabins and most traditional electric heaters require a dedicated 240V circuit — $500-$1,500 for an indoor run near the panel, $1,500-$3,800+ for a detached outdoor cabin requiring trenching. Combine the heater and the electrical work and a $17,990 Aura cabin can land closer to $23,000-$26,000 installed and running, not $17,990.
What’s genuinely different about Auroom
Auroom is part of the Thermory Group, the world’s largest producer of thermally modified wood, after being spun off as its own brand in 2021. That parentage is a real differentiator: Thermory’s core business is heat-treating wood to resist moisture and warping without chemical preservatives, which is the same property every sauna wood buyer actually cares about, and Auroom’s cabins draw directly on that supply chain rather than sourcing wood the way a smaller independent brand would. Per Estonian trade sources, Auroom’s factories in Tartu County now produce more than 4,500 saunas a year, a production scale closer to Harvia’s than to boutique cedar-barrel makers like Dundalk or Almost Heaven. Thermory also sells barrel saunas under its own name, separate from Auroom’s glass-wall cabins — see our Thermory sauna review for that lineup and pricing.
The brand’s defining visual signature — a full tempered-glass front wall on models like Cala Glass, Mira S, and Libera — is also a genuine design departure from the closed cedar-box look most outdoor sauna brands default to. Reviewers consistently describe it as reading more like a design feature than a backyard utility structure, which is a real consideration if the sauna is going somewhere visible rather than tucked into a back corner of the yard.
Auroom vs. the rest of the lineup: which fits you
- You want the cheapest way into the glass-wall look: the Cala Glass Mini at $7,590 is the lowest list price, but add the Harvia KIP package and 240V run before comparing it against a cheaper non-glass indoor cabin.
- You’re buying for a backyard and want a cabin, not a barrel: the Aura ($17,990) and Mira S ($14,990) are the entry points into Auroom’s outdoor glass-cabin format — see our best outdoor sauna guide if a traditional barrel fits your budget better.
- You’re outfitting for a group and don’t mind the heater math: the Arti scales to 5 people, but budget for the real $42,780 bundled figure, not the bare $38,990 kit price, if a dealer doesn’t disclose which number you’re being quoted.
The bottom line
Auroom is a legitimate premium player — part of the Thermory Group’s wood-treatment supply chain, producing over 4,500 saunas a year out of Tartu, Estonia — and its full-glass-wall design is a genuine departure from the cedar-box look most competitors default to. Pricing runs $7,590 to $18,800 indoors and $14,990 to $58,900+ outdoors, but that’s the cabin alone: budget an additional $1,846-$4,279 for the Harvia heater package most retailer listings price separately, plus the same 240V electrical work covered in our sauna installation cost guide. Confirm whether a quote already bundles the heater before you compare it against a different brand’s all-in price.
