❓ Frequently Asked Questions

Q: How many people can use the HEXXL at once? A: The HEXXL comfortably accommodates 8-10 adults seated on the double cedar benches. The spacious 3.5m × 1.8m footprint provides ample room for larger groups, retreats, or events.

Q: How long does it take to reach sauna temperature? A: With quality kiln-dried logs, the HEXXL reaches 90-100°C in approximately 25-30 minutes from lighting. Ambient temperature and wind conditions may affect heat-up time.

Q: Can I use the PortaSauna in winter? A: Absolutely. The triple-layer insulation retains heat effectively even in temperatures as low as -12°C. Many users prefer winter sauna sessions for the authentic Scandinavian experience.

Q: What type of wood should I use? A: Kiln-dried hardwood (birch, oak, or ash) with less than 20% moisture content provides the best results. Look for “Ready to Burn” certified firewood, which is a legal requirement in England for logs sold in smaller quantities.

Q: Can I leave the sauna up permanently? A: The HEXXL is designed for semi-permanent outdoor use. While built to withstand the elements, we recommend storing the stove indoors and covering or packing away the tent when not in regular use to maximise lifespan.

Q: Is the sauna safe for children? A: Children may use the sauna under close adult supervision. Children are more sensitive to heat, so monitor time carefully, ensure adequate hydration, and keep sessions shorter than adult use.

Q: What’s the warranty coverage? A: The tent is covered by a 3-year warranty against manufacturing defects, and the stove has a 1-year warranty. Contact Parts4Tubs for full warranty terms and support.

Q: Do I need planning permission? A: As a temporary, portable structure, the PortaSauna typically doesn’t require planning permission for domestic use. However, regulations vary by location – check with your local council if uncertain.
