Auroom Saunas
Auroom saunas, built in Vana-Kastre, Estonia
Built in Estonia. Planned with you. Installed once.
Auroom builds indoor sauna kits and outdoor cabins at its own factory in Estonia, with thermally modified wood from Thermory, its parent company. We walked that factory in September 2026 and watched a finished cabin get measured and sat in before it was taken apart to ship. You want a sauna that lasts and gets used. That starts with the right one for your space.

- A preferred Auroom partnerSupport and product knowledge from a team that has built these saunas and walked the factory. Popular models and spare parts are stocked in the Chicago area.
Which Auroom fits your space?
Pick where it goes and who will use it. Add the space you have if you know it. We show every model and size that fits, its price, and the heaters Auroom lists for that room.
We match the outside size either way round. Leave room around it for the door, wiring and air; each manual gives its clearances.
Three ways to own an Auroom. Tell us where it goes and how many people will use it, and we narrow it to the models and sizes that fit, with the heaters Auroom lists for each room.

We spent an afternoon at Auroom’s factory
In September 2026, on a trip to Thermory’s plants in Estonia, we walked Auroom’s factory in Vana-Kastre. It was a Friday, which our host told us is their shipping day. What stayed with us:
- Stood up before it shipsA finished cabin stood on the workshop floor while the crew checked its measurements and sat on the benches to make sure everything was right. Then it comes apart for the trip.
- Panels that go back in orderWall elements leave the line with a foil radiant barrier already on and numbers on their edges, so at your place they go together in order.
- Sorted by orderParts wait in the component store tagged with the order they belong to.
- Drilled to the planOn some builds the crew drills the holes for the sensor and lights where the buyer wants them, and even leaves a rope in the conduit so the electrician can pull the cable through.

There are some things you can’t learn without accepting the delivery yourself and building the sauna. These are ours, start to finish.

What the walls are made of
The indoor kits are framed, insulated wall elements with a foil radiant barrier on the hot side and finished wood on the faces, the same elements we saw stacked at the factory. They sit on an aluminum base frame that keeps the wood off the floor.
Outdoors, the Garda, Terra, Natura and Aura are built from cross-laminated timber, solid engineered wood panels, and the Garda, Natura and Arti carry an EPDM rubber roof. Inside most models is Thermory’s Thermo-Aspen; outside, thermo-spruce or thermo-pine.

Outside size is width by depth in inches. Prices are the sauna room before the heater; freight is calculated at checkout. Heater sizes come from Auroom’s heater chart for the heaters we carry; the heater’s own manual has the final word on your room.
What it takes to get an Auroom running
A sauna is a small construction project. Here is all of it, so nothing surprises you on delivery day.
- The roomThe model and size that fit your space and the people who will use it.
- The heaterFrom Auroom’s chart for that room, checked against the heater’s manual. Glass counts as extra room.
- The powerUsually a dedicated 240V circuit, run by a licensed electrician. The heater’s manual sets the breaker.
- The baseA level floor indoors. Outdoors, a level base, in before the ground freezes.
- The deliveryFreight in crates, calculated at checkout. Check every crate before you sign. The assembled cabins come on a flatbed.
We walk you through every one of these on a free call, and we’re still here after the crate is gone.
Auroom questions, answered
Does an Auroom sauna come with a heater?
No. Every Auroom price on this page is the sauna room: the walls, benches, door, lighting and Auroom’s accessory kit. You choose the heater separately, and most listings let you add a heater right on the product page. Auroom publishes a chart of the heaters it approves for each model and size; the finder above shows the ones we carry for the room you pick.
What size heater does my Auroom need?
Start with Auroom’s chart for your model and size, then check it against the heater’s own manual. Glass counts as extra room: HUUM’s DROP manual adds 3.3 cubic feet for every square foot of glass, and Harvia’s Spirit manual adds 3.94. That is why a glass front often takes a bigger heater. In Auroom’s chart, a Libera Glass 59 × 71 takes an 8 kW Harvia where the wood-front Libera of the same size takes a 6 kW.
Can I put a Saunum heater in an Auroom?
Yes. Auroom’s chart lists the Saunum Air for most of its indoor rooms and the Mira S, and the Air Perfect or Air L for the bigger rooms and cabins. See every Saunum heater with the room size it is rated for.
What electrical does an Auroom sauna need?
The heater sets it. Most need a dedicated 240V circuit run by a licensed electrician. As one example, HUUM’s DROP 7.5 kW draws about 31 amps and its manual calls for a 40 amp two-pole breaker and #8 copper wire. Check the manual for the exact heater you choose before your electrician quotes the job.
How long does an Auroom take to put together?
Auroom rates the Cala and Baia indoor kits at about 4 to 6 hours with two people, and the 1-person Cala Glass Mini at 3 to 4. The outdoor Mira L is a bigger job; our build video plans on two to three people and about two full days. The Garda, Arti, Terra and Natura arrive assembled.
Where are Auroom saunas made?
At Auroom’s factory in Vana-Kastre, Estonia. Auroom is part of Thermory Group, which makes the thermally modified wood inside most of its rooms. Auroom has three production units in Estonia and Latvia, capacity for more than 4,500 saunas a year, and more than 20 years of building saunas. We toured the Vana-Kastre factory in September 2026.
Glass front or wood front?
A glass front opens up the room and shows off the benches, and it fits a bathroom or a finished basement well. A wood front with a glass door keeps the room cozier and usually lets a smaller heater do the job. The Cala, Baia and Libera come both ways.
How does an Auroom ship?
Auroom’s most popular models and spare parts are stocked in the Chicago area and ship from there as freight in crates; others, like the Libera and Familia, are built to order in Estonia, so ask us for current timing. Freight is calculated at checkout from your address. When it arrives, check every crate and note any damage on the delivery receipt before you sign. It does not happen often, but it makes a fix much faster. The Garda arrives finished at about 4,000 lb on a flatbed, so plan how it will be lifted into place.
What warranty comes with an Auroom?
Two years from delivery for home use, under Auroom’s warranty terms, and no more than three years from the date it was made. Commercial use needs Auroom’s written OK. The heater and controls carry their own maker’s warranty. Read Auroom’s warranty. If anything comes up, we handle it with Auroom for you as a preferred Auroom partner, and spare parts are stocked in the Chicago area.
Can I get an Auroom that isn’t listed here?
Often, yes. Auroom builds more than we list, including the Nativa and Emma indoor kits, and its kits can be made to custom sizes in Europe if you have time to wait. Send us your space and we’ll get you a quote. And if Auroom doesn’t make the right sauna for you, we’ll tell you who does.
What comes in the box?
It depends on the model, and each product page lists its own. A Mira S, for example, arrives with pre-assembled wall elements, a backrest with LED lighting, a tempered glass door, a heater guard, a floor grid and Auroom’s accessory kit: bucket, ladle, thermometer, hygrometer, sand timer, aroma set, sauna hat and pillow. The heater is separate.
You’ve done the research. Now you need someone who’s done the build. Book a free 30-minute call with Ben Burger or Ben Frizzell, whichever is free first. Bring your partner and your measurements; we’ll bring the drawings.As low as the manufacturers allow.
We sell at the lowest price the manufacturers allow. You may find a discounter out there, but you’ll pay more in the end if the sauna is wrong for your space, or the seller never tells you what you need to know. With us you get the heater sized to your room, the spec diagram before your electrician shows up, freight sorted out, and someone to call long after the delivery.
Above and beyond is the job. Ben Frizzell once pulled the benches out of his own brand-new sauna and shipped them to a customer who was up against a deadline.
