❓ Frequently Asked Questions

Q: Where can I use the PortaSauna HEX? A: PortaSauna is designed for outdoor use only. It should be placed on a flat surface 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.

Q: How long does it take to heat up? A: The PortaSauna HEX reaches 90°C in under 20 minutes and can achieve 100°C+ in approximately 30 minutes, depending on ambient temperature and wood quality.

Q: Can I use it in winter? A: Absolutely! The triple-layer insulated fabric retains heat even in freezing temperatures. The HEX can reach 80-100°C even when it’s as cold as -12°C outside.

Q: Does the tent release any harmful chemicals? A: No. The PortaSauna HEX has been professionally air quality tested. Test results confirm no carbon monoxide or volatile organic compounds at operating temperatures. The inner lining uses CPAI-84 flame-retardant material for added safety.

Q: What type of wood should I use? A: Use dry, seasoned hardwood logs for best results. Kiln-dried logs produce less smoke and more consistent heat. Avoid treated wood, painted wood, or softwoods that produce excessive smoke.

Q: How many people can use it at once? A: The HEX comfortably seats 4 people and can accommodate up to 6 for shorter sessions.

Q: Can I leave it set up permanently in my garden? A: While the weatherproof design allows extended outdoor use, we recommend using the waterproof cover provided and storing the stove indoors when not in use. To maximise lifespan, pack the sauna away when not in regular use.

Q: What is included in the complete kit? A: The full package includes the HEX tent, 430 stainless steel stove with chimney, cedar bench, olivine diabase sauna stones, sauna hats (2-4), metal bucket and ladle, fire-retardant gloves, thermometer/hygrometer, fire starters and matches, and instruction/safety manual.

Q: What maintenance is required? A: The PortaSauna is designed for easy care. The high heat naturally dries out moisture. Simply empty the ash tray and clean the chimney every few uses. Periodically check tent fabric for any damage.

Q: Is financing available? A: Yes, 0% finance options are available through authorised retailers including Parts4Tubs.
