Where can I use PortaSauna?
PortaSauna is designed for outdoor use only. It should be placed on a flat surface and at least 120 cm (4 ft) away from buildings, fences, trees, and other structures. If using in a campsite or public area, check with the site operator for permission.
Can it be used in Winter?
Absolutely! The triple-layer insulated fabric of the PortaSauna HEX retains heat even in freezing temperatures. It can reach 80-100°C, even when it’s as cold as -12°C outside.
Does PortaSauna release any chemicals? What is the tent made of?
Yes! The PortaSauna HEX is built with safety and air quality in mind.
- The tent is made from heat-resistant Oxford 600D fabric, rated up to 150°C, ensuring durability without releasing harmful chemicals.
- The windows are high-performance TPU, designed to withstand high temperatures.
- The interior is lined with CPAI-84 flame-retardant material, adding an extra layer of fire safety.
Air Quality Tested & Verified:
PortaSauna HEX has undergone professional air monitoring tests for:
🔹 CO₂ (Carbon Dioxide) – Ensuring proper ventilation.
🔹 PM2.5 & PM10 (Fine Particulate Matter) – Checking for airborne particles.
🔹 Formaldehyde (HCHO) – Confirming no off-gassing from materials.
🔹 AQI (Air Quality Index) Particles – Measuring overall air purity.
Why is this important? These tests guarantee that the air inside the sauna remains safe to breathe at high temperatures, making PortaSauna HEX a chemical-free, safe, and health-conscious sauna option for regular use.
What prevents PortaSauna from blowing over in the wind?
The PortaSauna HEX has a double-skirt design for added stability. In windy conditions, we recommend anchoring it with sandbags, bricks, or cinder blocks. Ground stakes and ropes are also included for extra reinforcement.
Can you leave PortaSauna outside permanently?
Yes, but we recommend using the included waterproof cover for protection. If left outside long-term, extreme weather conditions may affect durability. Storing it indoors when not in use will prolong its lifespan.
Does PortaSauna require cleaning?
Minimal maintenance is needed! Moisture naturally evaporates due to the high heat. Simply empty the ash tray and clean the chimney every 3-4 uses to maintain airflow.
What are the dimensions of the PortaSauna HEX?
📏 Assembled size:
- 1.8m (L) x 1.8m (W) x 2.1m (H)
- Exterior tent skirt extends the footprint by 15cm on each side.
Tips for operating the stove?
Best practices for heating:
- Keep the air vent fully open for proper airflow.
- Start with fire starter squares and dry hardwood (30-40 cm logs).
- Close the stove door for 15 minutes before adding more wood.
- Adjust airflow and wood supply to control heat levels.
Is it okay for the stove to turn red hot?
Yes! The stove and chimney may glow red at high temperatures. This is safe, but if concerned, reduce airflow to slow the burn rate.
PortaSauna Stove Maintenance – FAQ
Proper care of your wood-fired sauna stove will extend its lifespan and ensure safe, efficient heating. Follow these maintenance tips to keep your stove in top condition:
🔥 Keep Your Sauna Stove Dry
✔ Store indoors when not in use for extended periods to prevent rust and erosion. If leaving the sauna tent set up for regular use, cover the stove with a waterproof cover.
✔ Use the PortaSauna waterproof cover to Cover the flue hole to prevent rainwater from dripping onto the stove,
💦 Water Use & Steam Safety
✔ Only pour water onto the sauna stones—never directly onto the stove. Water on hot metal can cause thermal shock, leading to warping and cracking.
✔ Never use seawater. The salt can cause severe corrosion to the stove and chimney.
✔ For infusions, use ice balls infused with essential oils—never apply essential oils directly to the stove as they can ignite.
❄️ Cooling Down the Stove
✔ Allow the stove to cool naturally after each session. Do not throw water on it, as sudden temperature changes can warp the metal.
🧹 Regular Cleaning & Ash Removal
✔ Remove ash only when the stove is completely cooled. Built-up ash retains moisture, leading to stove corrosion and less efficient heating.
✔ Check the chimney regularly to ensure proper airflow and prevent blockages.
By following these guidelines, you’ll keep your PortaSauna HEX stove in peak condition, ensuring a long-lasting and enjoyable sauna experience!
What makes your tents different from regular camping tents for using as a sauna or sleeping overnight?
Regular camping tents have chemicals on them for protection from sun and fire. These chemicals can be harmful if the tent gets very hot, like in a sauna, and can hurt your lungs. These tents also have materials and zippers that might not work well in high heat. Our tents are made especially for saunas. They can handle very high temperatures and don’t have harmful chemicals. This means they are safe to breathe in. Our tents have doors that swing open, making it easy to get in and out, so you won’t get stuck in a hot sauna tent. We make each tent by hand with strong materials, so they last long and work well in tough conditions.
Why is PortaSauna better than an infrared or fixed sauna?
✔ No building permits needed – portable & hassle-free.
✔ Authentic sauna experience – reaches 90-100°C with real steam (löyly).
✔ Safe materials – no toxic coatings, unlike camping tents.
✔ Versatile – use it anywhere outdoors, whether at home, the beach, or a campsite.
Why Smoke is Coming Out of Your PortaSauna Stove Door?
If using the stove for the first time, run a pre-burn for an hour without stones to cure the paint. If smoke continues, check for chimney blockages or air leaks, and ensure proper airflow.
Is there a warranty?
Yes! PortaSauna comes with a 1-year warranty covering manufacturing defects. This does not cover normal wear and tear, misuse, or unauthorized modifications. Repairs beyond the warranty period are available at cost.
Temperature does not rise?
To maximize heat:
- Use dry hardwood (softwood burns too fast).
- Anchor the tent properly to minimize cold air gaps.
- Allow stones to heat for 30-60 minutes before entering.
- Limit water pouring to every 10 minutes, as excess steam can lower the overall temperature.
Smoke comes from the stove body?
For the initial use of the sauna, conduct a pre-combustion or ‘dry firing’ process for about an hour without the sauna stones, until there is no detectable odor or smoke. This is necessary because the paint on the stove may not be fully cured, leading to the emission of smells and smoke from the stove’s surface. If smoke is observed due to any holes or similar issues, cease using the sauna and send it for maintenance.
Can the stove warp over time?
Some warping is normal due to high heat exposure, but it does not affect performance. If severe, maintenance services are available.
What do I wear?
Recommended attire:
- Loose-fitting clothes or swimwear
- Sauna hat to protect hair from heat
- Sandals for comfort and hygiene
Where can I use my PortaSauna?
PortaSaunas can be used anywhere there is a flat space where the tent can be spread out. We recommend at least 4 ft (120cm) from any fence, building or vegetation. Also check above for hanging branches.
If you wish to use it in a campsite or commercial setting it is recommended that you ask for permission before you set up. Smoke will be generated, so please be mindful of others when using the PortaSauna
How much firewood is needed? What are the running costs?
We recommend using 30cm-long dry hardwood logs for the best burn efficiency. The exact amount depends on the wood type and moisture content, but typically:
💰 Estimated cost: The running cost of a PortaSauna session ranges between 50p to £1 per hour, depending on firewood type, local pricing, and purchase quantity.
What is the danger of carbon monoxide poisoning?
PortaSauna is designed for safe ventilation, but follow these precautions:
✅ Keep the tent’s air vents open
✅ Ensure the chimney is clear before lighting
✅ Only burn dry wood—no treated wood or charcoal
✅ Use a CO monitor for extra safety
What should I be careful about in terms of safety?
Wood-burning stoves reach high temperatures, so be sure to use heat-resistant gloves when adding firewood.
When adding water to sauna, be careful not to come into contact with high-temperature steam.
Be careful not to touch the stove when entering or exiting the sauna tent.
What kind of weather is not suitable?
🚫 Not recommended in:
- Heavy rain (the sauna is water-resistant, not fully waterproof)
- High winds (risk of chimney backflow)
- Heavy snowfall (may block the chimney)
What about maintenance?
After each use:
- Dry the tent completely before packing it away
- Clean ash from the stove and remove soot from the chimney
- Store the stove in a dry room to prevent rust
- Apply silicone spray to zippers for longevity
I want to make my tent last longer.
Since zippers are frequently used, apply silicone spray to them to prevent damage.
The zipper handle gets hot, so attach a string or tape to it.
Always follow instructions to increase longevity of the PortaSauna products.
Can children use it?
Yes, but only under supervision. Children are more sensitive to heat, so monitor their time inside and ensure they stay hydrated.
