What is a sauna tent?
A sauna tent is a portable sauna made of insulated specialty fabric combined with a wood-burning stove. Unlike a permanent sauna, you can set it up anywhere in under 15 minutes – without a building permit, without concrete, and without an electric cable. The result is a genuine sauna experience with temperatures of 100 °C+, the possibility of löyly (steam bath with water on the stones), and direct contact with nature.
Short answer: What makes a sauna tent unique?
Portable, quick setup, no building permit, works year-round, and costs a fraction of a permanent sauna. It provides full sauna heat wherever you are.
The sauna tent is perfect for the outdoor enthusiast who wants to set up the sauna by a fishing spot, the family with children who want a sauna evening in the garden, and the cabin owner who lacks space or budget for a permanent building. It is also an excellent option for winter bathing – stream up from the ice hole, into the hot tent, and out again.

How to set up a sauna tent – step by step
One of the strongest reasons sauna tents have become so popular is their simplicity. The Flame is a popup tent that expands in five minutes. The Spark is manually assembled with tent poles in about ten minutes.
- Choose a location – level ground, at least 2 meters of free space around the tent, and a clear path for the smoke.
- Unfold the tent – The Flame: Pull out the corners and the tent will automatically unfold. The Spark: assemble the tent poles and insert them into the channels running along the bottom of the tent corners.
- Anchor – hammer down the tent pegs and tighten the storm lines, especially important in windy conditions.
- Place the stove – set the stove on the fireproof stove mat in the tent.
- Assemble the pipe – connect the stove pipes and push out through the roof opening.
- Light the fire – add dry birch wood and open the damper for quick startup.
- Wait – The Spark: 10–15 min to 100 °C. The Flame: 20–25 min. Then throw water on the stones for löyly.
Tip: Position the tent with the door sheltered. Birch wood provides long, even heat and is the classic choice for Nordic sauna tradition.
How long does it take to heat up a sauna tent?
Direct answer: Heating time HOTT SAUNA
The Spark: 15–20 minutes to 100 °C (small volume, efficient stove).
The Flame: 25–30 minutes to 100 °C (larger volume, 7 windows with large panorama).
The integrated stone reservoir in The Beast stove is a key detail: the stones are heated directly by the stove without a separate stone basket, allowing for faster heat distribution and more efficient löyly. The protective casing on the stove also shields against the direct radiant heat that can otherwise burn the legs – a common problem with some other sauna stoves.

Materials and construction – what to consider?
Oxford 300D – the standard material for quality sauna tents
Oxford 300D is a tightly woven polyester fabric with good tear strength and water repellency. HOTT SAUNA uses a 3-layer construction: outer fabric / insulation / inner fabric, providing superior heat retention.
PFAS-free flame retardant – why it matters
Traditional flame retardants contain PFAS chemicals (poly- and perfluoroalkyl substances), linked to health risks with repeated exposure in hot environments. Both HOTT SAUNA models use flame retardants completely free of PFAS – important when inhaling hot air in direct contact with the tent's interior during sauna sessions.
YKK zipper
YKK is the industry standard for durable and reliable zippers. Cheaper sauna tents use generic zippers that wear out faster with regular use.
Sauna tents for year-round use and winter bathing
The combination of sauna tent and winter bathing has become one of the most popular outdoor trends in Scandinavia. Bathe in an ice hole, jump into the sauna tent, warm up for 10–15 minutes, repeat. Gnistan is ideal for setting up at baths when out on an adventure.
Can the sauna tent be left outside permanently?
Yes – but we recommend a weather protection cover during longer periods of snow or sunny conditions to extend the lifespan.
Portability – what really distinguishes sauna tents
What separates a genuine outdoor sauna tent from a "garden kit" is the carrying system. Both HOTT SAUNA models come with dedicated carrying bags for the tent and stove, with real backpack straps – not handles. This means you can carry the entire sauna on your back out to the lake, up the mountain, or down to the dock.
Gnistan weighs ~11 kg and is the obvious model for longer carrying distances. Flamman at ~22 kg is comfortable for two people to transport and is optimized for easy handling close to home or the cabin.
Frequently asked questions about sauna tents
Do you need a building permit for a sauna tent?
No. The sauna tent is a temporary, portable structure that is not permanently anchored to the ground and does not require a building permit in Sweden. Check with your local municipality if you are in a protected beach area or nature reserve.
How long does a sauna tent last?
With proper care – dry the tent thoroughly before storage, keep it dry, and clean the stove pipes regularly – a quality sauna tent lasts 5–10 years. Protection from sun, rain, and snow is a prerequisite for long durability. Quality components, YKK zippers, and 300D fabric are the most important factors for long lifespan.
How much does a sauna tent cost?
A complete sauna tent package of good quality usually costs 15,000–30,000 SEK depending on the model and package level. A one-time investment compared to a permanent sauna that can cost ten to twenty times more.
What wood is best for a sauna stove?
Dry birch wood is the classic choice – it burns long and evenly with a pleasant scent. Avoid damp wood (causes soot) and plastic-treated lumber (toxic smoke).
How do you take care of a sauna tent?
Dry the tent thoroughly before packing it up. Do not wash the tent fabric in a machine – it can remove the waterproofing and fire retardant treatment. Clean the stove pipes frequently with a chimney brush to avoid soot buildup. Store in a dry, dark, and cool place.
Can you use a sauna tent in winter?
Absolutely. Sauna tents can be used all year round. Even when the temperature is well below zero degrees. Hott sauna's sauna tents are tested in extreme cold and reach 100 degrees even at minus -30 degrees
