WHAT TO LOOK FOR
Which sauna tent should you buy in 2026?
Six things separate a good sauna tent from a bad one: the quality of the materials and components, test reports, how hot it gets, what's included in the box, warranty and spare parts. This page compares bast with the rest of the market on all six.

In short
In a product photo, every sauna tent looks the same. The difference only shows after a couple of seasons - in the stove, in the accessories that come with it, and in how long the tent lasts. That's where we've put the work: thicker steel in the stove, materials tested by independent institutes, and spare parts you can order when something wears out. If you're only after the lowest one-off price, there are cheaper tents - we're honest about that. If you want a sauna that lasts year after year, this is the comparison you'll want to read.

value documented safety and performance over the lowest price
want to be able to replace components easily and get personal advice before and after purchase
bast is wrong for you if you:
are after the cheapest possible one-off purchase
plan to use the sauna only a few times

High-quality sauna, made to last
It's our second tent sauna. Before, we had a Russian-made Mobiba, which we thought was fantastic, but bast beats it in many ways: easy to set up, a protective cover against the weather, and the overall high quality of both the tent and the stove. It's a solid product that we'll enjoy for many years.

Best customer service around!
The customer service at bast is second to none! Any time I've had an issue or concern, they're quick to respond and do their best to solve it quickly and efficiently.
It hasn't been without snags, and they've been humble enough to take feedback on board and are always keen to improve their product. I trust these guys!

Only had the sauna a month, but…
I've only had the sauna for a month, but so far I'm very satisfied with how quickly you can set it up, and it takes about 30 minutes to reach 80 degrees - I've managed to get it to 100 degrees too. The stove doesn't need much wood to stay hot. Even in the rain it stayed dry inside. I'm very happy with this purchase.
What buyers ask most
Common questions about buying a sauna tent.
bast uses 300D Oxford fabric with a double PU coating and double-stitched seams, plus a stainless 304 chimney with a spark arrester - materials dimensioned for 10+ years of use. The construction was developed together with the Technical University of Luleå and third-party tested by TÜV SÜD and RISE - get in touch and we'll gladly tell you more.
You get a 2-year warranty and always have access to spare parts. Every component - tent pole, chimney pipe, stove door, tent fabric - can be ordered separately if something breaks. If you're not happy with your bast within 100 days, we'll take it back and refund you. Read the terms here.
Yes. With a wood-fired bast stove, a Näver sauna tent reaches around 80 °C in 15 minutes at an outdoor temperature of about -10 °C. In colder conditions, heating takes longer - exactly how long depends on wind, wood and outdoor temperature. That's the same temperature level as a commercial sauna.
Many portable sauna tents on the market need 20-30 minutes for the same temperature, and some never get above 70 °C.
The best way to answer that is to look at what you actually pay over time, not just the price tag. When you buy a bast, the stove, stones, bag, benches and weather protection and more are included. Shipping is free and you have a 30-day right of return plus a 100-day satisfaction guarantee.
When you compare with other portable sauna tents, the total package often comes out several thousand kronor higher once the accessories are counted in. Add a typical lifespan of 2-4 years for cheaper alternatives, and the picture over 5 years looks different. Want us to do the maths for your specific case? Get in touch and we'll help you.
Yes - and that's how most of our customers use it. Löv (210 × 210 cm) fits most plots; Näver (270 × 270 cm) suits a smaller garden or terrace; Björk (330 × 330 cm) needs a larger area. All three can stay up permanently all year round or be taken down in about 15 minutes when you're not using them.
No planning permission or shoreline protection to worry about - the sauna doesn't count as a permanent building.
Four things are concrete and verifiable:
1. Two independent test reports. TÜV SÜD and RISE. Most portable sauna tents lack independent assessment entirely.
2. Designed together with the Technical University of Luleå. Construction developed in collaboration with a technical university - rare on the market.
3. Everything's included in the package. We have four different packages tailored to what you want.
4. 100-day satisfaction guarantee + replaceable components. If you're not happy, you get your money back. And every component can be ordered individually.
Material- and performance-specific comparisons can be found in the tables above.
