Sun Home offers three notably different outdoor-sauna choices: the compact Luminar 2, the roomier Luminar 5, and the fully assembled Solaris 4. The Luminar models use full-spectrum infrared heat, while the Solaris provides the hotter, steam-capable experience of a traditional sauna.
The best choice depends on more than price. Capacity, preferred heat style, electrical requirements, site preparation, delivery, assembly, and warranty coverage all differ. This comparison explains those differences so you can determine which model best fits your backyard, household, and budget.

Luminar 2: Best for Couples and Smaller Outdoor Spaces
The Luminar 2 is the most compact and least expensive outdoor sauna in this comparison. It is designed for two people and combines six full-spectrum heaters with three far-infrared heaters. Its Canadian red cedar interior is enclosed by an aerospace-grade aluminum exterior intended for year-round outdoor placement.
This model is the strongest fit for a couple, an individual who wants extra room, or a homeowner with limited patio space. It reaches a listed maximum temperature of 170°F and includes app connectivity, Bluetooth audio, chromotherapy lighting, an oxygen ionizer, and an all-weather cover. Red light therapy is available as an optional upgrade.
Key Specifications:
- Capacity: 2 people
- Heat: Full-spectrum and far-infrared
- Electrical: Dedicated 240-volt, 20-amp GFCI circuit with a NEMA L6-20 outlet
- Interior: Canadian red cedar
- Exterior: Aerospace-grade aluminum
- Maximum temperature: 170°F
- Warranty: Limited lifetime
- Current listed price: $10,999

Luminar 5: Best for Families and More Interior Space
The Luminar 5 delivers the same outdoor construction and full-spectrum infrared experience as the Luminar 2, but with substantially more interior room. It uses ten full-spectrum heaters and five far-infrared heaters and provides seating for up to five people.
This model is best suited to families, households that expect to share the sauna with guests, or buyers who want enough bench space to stretch out. The larger cabin requires more patio space and a higher-capacity electrical circuit, but its additional room may justify the price difference for frequent multi-person use.
Key Specifications:
- Capacity: 5 people
- Heat: Full-spectrum and far-infrared
- Electrical: Dedicated 240-volt, 30-amp GFCI circuit with a NEMA L6-30 outlet
- Interior: Canadian red cedar
- Exterior: Aerospace-grade aluminum
- Maximum temperature: 170°F
- Warranty: Limited lifetime
- Current listed price: $13,899

Solaris 4: Best for a Traditional High-Heat Sauna Experience
The Sun Home Solaris 4 is designed for buyers who prefer the intense heat and traditional experience of a stone-heater sauna. Its four-person cabin combines a Thermo-Alder interior with a 6 kW HUUM heater and reaches temperatures up to 230°F, offering a distinctly different experience from the gentler infrared heat of the Luminar models.
Because the Solaris 4 arrives fully assembled, buyers need an accessible delivery path and a level, load-bearing foundation prepared in advance. It also requires dedicated 240-volt, 30-amp hardwired electrical service, so site preparation and installation costs should be confirmed before ordering.
Key Specifications:
- Capacity: Up to 4 people
- Heat type: Traditional electric sauna with stones
- Heater: 6 kW HUUM DROP heater
- Electrical: Dedicated 240-volt, 30-amp hardwired service
- Interior: Thermo-Alder wood
- Maximum temperature: 230°F
- Warranty: 3 years
- Current listed price: $36,399

Which Sun Home Sauna Is Right for You?
The best choice depends primarily on the number of people who will use the sauna, the type of heat you prefer, your available space, and the electrical and site-preparation requirements your property can accommodate.
- Choose the Luminar 2 if you want an infrared sauna for one or two people and need the smallest footprint and lowest price of the three models.
- Choose the Luminar 5 if you prefer infrared heat but need more room for a family, guests, or extra personal space.
- Choose the Solaris 4 if you want a traditional high-temperature sauna with heated stones and can accommodate its larger investment, hardwired electrical service, foundation, and delivery requirements.
What to Confirm Before Ordering
Before placing an order, confirm the full installation requirements—not only whether the sauna will fit in the intended location. Electrical work, foundation preparation, delivery access, permits, and professional installation can add to the total project cost and may need to be arranged before the sauna arrives.
- Verify the exterior dimensions and required clearance around the sauna.
- Confirm the correct dedicated electrical circuit, plug or hardwired connection, and local code requirements with a licensed electrician.
- Determine whether a concrete pad, deck, or other load-bearing foundation is required.
- Measure gates, walkways, overhead obstructions, and other portions of the delivery path.
- Confirm what delivery, placement, assembly, and electrical services are included or must be arranged separately.
- Review the current warranty, return policy, lead time, and total delivered cost.
Final Thoughts
The Luminar 2, Luminar 5, and Solaris 4 are designed for different buyers rather than representing a simple good-better-best progression. The Luminar models provide full-spectrum infrared heat in two sizes, while the Solaris 4 delivers the hotter, more traditional experience of an electric heater and sauna stones.
The right model is the one that matches your preferred sauna experience while fitting your household, property, electrical capacity, and overall budget. Confirm current specifications, availability, warranty terms, and installation requirements with Sun Home before making a final purchase decision.
