Solaris Saunas by Sun Home

---

The Sun Home Solaris is one of the most architecturally advanced outdoor traditional saunas available today. Built entirely in Europe, assembled over 100+ hours, and delivered as a fully constructed structure, the Solaris is designed for homeowners who want a permanent, luxury outdoor sauna with true Finnish heat, premium materials, and long‑term durability.

Available in 4‑person and 6‑person configurations, the Solaris combines Thermory® wood, HUUM high‑output heaters, triple‑layer glass, and marine‑grade hardware to create a sauna that performs reliably outdoors year‑round. 

The Solaris is engineered as permanent outdoor architecture, not a kit or panel sauna. It arrives fully built, with only electrical hookup required. This makes it unique among outdoor saunas, which typically require multi‑day assembly or lack the structural integrity needed for long‑term outdoor exposure.

Key defining features include:

• 220°F+ traditional heat from HUUM Wi‑Fi electric heaters 
• Thermory® thermally modified wood for weather resistance and dimensional stability 
• Triple‑layer toughened glass for insulation and panoramic views 
• High‑density insulation built into the frame for consistent heat and fast recovery after door openings 
• Marine‑grade stainless steel hardware for long‑term outdoor durability 

This combination places the Solaris in the top tier of outdoor traditional saunas globally.

Thermory® wood is thermally modified to resist moisture, warping, and outdoor weather conditions. It is widely used in high‑end architectural projects due to its stability and longevity. The Solaris uses this wood throughout the frame and offers multiple finish options to match modern outdoor spaces. 

The Solaris uses expansive triple‑layer glazing that is both heat‑resistant and insulating.

• Solaris S: 8mm glass
• Solaris M: 32mm double‑pane glass   This ensures heat retention while maintaining a bright, open cabin feel. 

Unlike many outdoor saunas where insulation is added after construction, Solaris integrates insulation directly into the frame. This results in:

• Faster heat‑up times
• More stable temperatures
• Better performance in cold climates 

All structural fasteners are marine‑grade stainless steel, preventing corrosion even in harsh outdoor environments. 

The Solaris uses high‑output HUUM heaters capable of reaching 220°F+, delivering authentic Finnish sauna heat. HUUM is known for:

• Fast heat‑up
• Deep, consistent heat
• Rock‑based thermal mass
• Wi‑Fi app control

This allows you to preheat the sauna remotely — a major convenience for outdoor installations. 

• Volume: 224 cubic feet
• Power: 240V / 25A (30A breaker) 

• Volume: 287 cubic feet
• Power: 240V / 40A 

Both models share:

• 79" cabin height
• Same exterior width
• Deeper footprint on the 6‑person model 

The Solaris is one of the simplest outdoor saunas to install because it arrives fully built.

• Level, load‑bearing outdoor pad
• Sauna weight: 1,700–1,900 lbs
• 6 inches of clearance on each side
• Clear delivery path for a fully assembled structure 

• Dedicated 240V service
• 30A breaker for Solaris 4
• 40A power supply for Solaris 6
• Hardwired by a licensed electrician 

• Built in Europe
• 100+ hours of assembly before shipping
• 3–4 month lead time
• Arrives structurally complete; electrician performs final hookup 

This makes Solaris one of the few “plug‑in‑and‑use” outdoor traditional saunas on the market.

With true 220°F+ heat and a fully insulated cabin, the Solaris supports:

• Deep detoxification
• Cardiovascular conditioning
• Muscle recovery
• Stress reduction
• Improved sleep
• Enhanced immune function

The combination of high heat, stable insulation, and HUUM’s rock‑based thermal mass creates a traditional sauna experience comparable to high‑end Nordic spas.

Choose the Solaris if you want:

• A permanent outdoor sauna with architectural quality
• True traditional Finnish heat
• A fully assembled unit with minimal installation hassle
• Premium materials designed for decades outdoors
• A modern aesthetic with panoramic glass

Avoid the Solaris if you prefer:

• Infrared therapy
• Portable or budget outdoor saunas
• DIY assembly kits

The Sun Home Solaris is one of the most impressive outdoor traditional saunas available today. Its combination of Thermory® wood, triple‑layer glass, HUUM heaters, and European craftsmanship makes it a standout choice for homeowners seeking a luxury, long‑term outdoor wellness installation.

If your goal is authentic heat, architectural beauty, and zero assembly, the Solaris is a top‑tier investment that delivers spa‑grade performance year‑round.
