Brightenwells Boreas Sauna 3
Brightenwells Boreas Sauna 3
Boreas 3 is a compact, high-end outdoor single sauna designed for a modern minimalist lifestyle, offering a pure and complete sauna experience within a limited space. Its core design philosophy revolves around "solitude, relaxation, and a return to bodily instincts," making it ideal for those seeking privacy and a high-quality lifestyle.
The entire sauna is meticulously crafted from 1.57-inch (approximately 40mm) thick ThermoWood® heat-treated wood. This wood undergoes high-temperature steam treatment, providing excellent moisture resistance, dimensional stability, and weather resistance, allowing it to withstand long-term outdoor conditions while emitting a warm, natural woody aroma. Its clean, restrained exterior lines present a modern architectural feel, blending harmoniously with natural landscapes and contemporary residences.
The interior is warm and quiet, with delicate, natural wood grain creating a relaxing yet understated atmosphere. A carefully designed intelligent ventilation system ensures continuous airflow while maintaining thermal efficiency, making each steam cycle more comfortable and pure, truly replicating the breathing sensation and temperature variations expected in a traditional sauna.
The Boreas 3 boasts exceptional adaptability, seamlessly integrating into urban terraces, rooftop gardens, or private courtyard corners. It's space-saving yet impactful, providing a tranquil retreat in everyday life.
Furthermore, the product supports various personalized configurations:
Optional soft LED ambient lighting creates warm and restrained layers of light and shadow within the steam;
It can be paired with a decorative hexagonal back panel to add depth and design to the interior, giving your private sauna a truly exclusive character.
The Boreas 3 is more than just a sauna; it's a daily wellness ritual—sweating in tranquility, releasing tension in the steam, and restoring balance to body and mind in solitude.

🌿 Sauna room precautions
1.Do not use on a full or empty stomach - wait at least 1 hour after a meal before entering the sauna
2.Control your time – 10–15 minutes per session is recommended. Increase gradually to avoid overdoing it.
3.Hydrate properly – Drink enough water before and after your sauna session to avoid dehydration.
4.Avoid alcohol – it increases stress on the heart and the risk of dehydration
5.If you have any health problems, please consult a doctor first - especially if you have heart disease, high blood pressure, or are pregnant.
6.Children must be accompanied by an adult when using this product – and use it for a shorter time and at a lower temperature.
7.The cool-down process is equally important – showering after the sauna or relaxing at room temperature helps restore circulation.
8.Turn off the power before leaving – for safety and energy savings.
