Health Benefits.

Why Traditional Sauna?

Traditional saunas heat the air and stones around you, creating an intense, enveloping warmth throughout the cabin. Adding water to the heated stones produces a burst of steam, allowing you to adjust the humidity and shape each session to your preference.

The higher temperature encourages the body’s natural cooling response, raising heart rate and promoting perspiration. It is a simple, time-tested way to warm up, slow down and create space away from everyday distractions.

Key Benefits

Traditional sauna bathing can support physical and mental wellbeing as part of a balanced lifestyle.

  • Post-Workout Recovery: Sauna heat increases blood flow and helps tired muscles relax, making it a useful addition to a post-exercise recovery routine.
  • Relaxation and Stress Relief: The combination of warmth, quiet and time away from screens creates a calm environment in which to switch off and decompress.
  • Joint Mobility and Muscle Tension: Sustained heat may temporarily ease muscular tension and stiffness, helping the body feel more comfortable and mobile.
  • Cardiovascular Response: As the body warms, heart rate and circulation increase. Regular sauna bathing has been associated with cardiovascular benefits, although it should complement not replace exercise and medical care.
  • Sleep and Evening Wind-Down: A sauna session can provide a clear transition between a busy day and rest, with research suggesting regular sauna bathing may support sleep and mental wellbeing.
  • Cleansing Perspiration: Sauna heat encourages sweating, helping wash away surface oil and impurities when followed by a shower. It does not “detox” the body the liver and kidneys already have that particular job covered.

FREQUENTLY ASKED QUESTIONS.

How many people can use the Arch?

The Arch is designed for up to two adults. It provides comfortable shared seating while remaining compact and inviting for solo sessions.

Is the Arch suitable for a small garden?

Yes. Its external footprint is 167 × 120cm, making it relatively compact for a two-person outdoor traditional sauna. Additional space must be allowed for access, ventilation, installation and maintenance.

Is the Arch an infrared sauna?

No. The Arch is a traditional sauna. Its 6kW Harvia heater warms the cabin, timber and sauna stones to create a high-temperature bathing environment.

Is the Harvia heater included?

Yes. A 6kW black Harvia electric sauna heater is included with the Arch. Confirm separately whether sauna stones and any external controls are included with your exact package.

Can water be added to the sauna stones?

Water may be carefully added to suitable heated sauna stones to create short bursts of steam. Always follow the heater manufacturer’s operating instructions and never pour water onto an uncovered heating element.

What electrical supply does the Arch require?

The 6kW heater requires a dedicated electrical supply and cannot be connected to a standard 13A plug.

The heater must be installed by a qualified electrician. Final circuit protection, cable size and isolation requirements must be determined from the exact Harvia heater documentation and the conditions at the property.

Do you offer installation services?

Yes, installation is available for an additional charge.

What base does the Arch require?

The sauna must stand on a firm, completely level and suitably load-bearing base. The structure alone weighs approximately 450kg, so the base must also allow for the heater, stones and occupants.
