Leil Como 4-180 4-Person Indoor Sauna

Yes, the Como 4-180 is engineered for comfortable 4-person use with its spacious 1.69-meter interior width and innovative three-level bench system. The configuration includes two top benches, one extended bottom bench, and a step bench, all with integrated backrests. This allows four adults to sit at different heights with ample room and support, or allows flexible positioning such as two people reclining on top benches while two sit upright on lower levels. The 2,085mm interior height accommodates seated and reclined positions for extended group wellness sessions.

The Como 4-180 exterior dimensions are 1,810mm wide x 1,600mm deep x 2,200mm tall. For proper installation and access, plan for a room at least 2,400mm x 2,200mm (7’10” x 7’2″) minimum, with 600mm x 720mm clearance space on all sides recommended for ventilation, airflow, and maintenance access. The sauna can be positioned in a corner by assembling wall logs first, then pushing against walls, but ensure adequate ventilation around the roof area. A ceiling height of at least 2,400mm is recommended to accommodate the 2,200mm sauna plus airflow above.

Heaters are sold separately and not included with the sauna kit. For the Como 4-180’s 5.0+ cubic meter interior volume, we recommend electric heaters in the 8-11kW capacity range. Leil particularly recommends HUUM Drop 9 (9kW) which features patented air-blending technology that mixes hot ceiling air with cooler floor air, creating balanced warmth and eliminating “cold feet” for four people. Alternative options include higher-capacity Saunum or Harvia KIP 8 models. Consult manufacturer heater sizing recommendations or contact sales to match your specific heat output needs for larger group sessions.

The Como 4-180 uses pre-fabricated modular wall logs that are easier to assemble than traditional barrel staves. Four to five capable people can complete assembly in 7-10 hours following the detailed installation manual included with your kit. Four to five people are recommended for handling the larger wall panels and installing the heavy tempered glass door safely. No professional installation is required if you have basic tools (hammer, screwdriver, drill) and follow instructions carefully. However, electrical wiring must be completed by a certified electrician to ensure safety and compliance with local electrical codes.

ThermoWood® is Scandinavian pine that is heat-treated using only heat and steam (no chemicals) to remove internal moisture and resins. This thermal modification creates wood that is naturally resistant to warping, shrinking, rotting, and insect damage—far superior to untreated cedar, hemlock, or softwoods. ThermoWood® won’t leak sticky resin even in extreme heat, maintains dimensional stability for decades without twisting, and develops a beautiful natural patina over time. The Como 4-180’s 40mm thick ThermoWood® walls provide exceptional insulation, heat retention, and durability compared to standard sauna materials, supporting frequent group use.

Yes, the Como 4-180 offers excellent customization options. You can add optional LED lighting systems in multiple configurations that provide warm ambient illumination across the larger interior space. The standard back wall can be upgraded to a large Hexagon DECO decorative panel (1684mm x 1593mm) that adds visual elegance and spa-quality aesthetics to complement your interior design. These options can be selected during purchase or added as upgrades, allowing you to personalize your group wellness space and create the perfect atmosphere for family gatherings and entertaining.

The Como 4-180 includes a comprehensive 2-year manufacturer’s warranty covering defects in materials, manufacturing quality, and any damage occurring before transportation delivery. The warranty does not cover natural wood variations (such as color changes, knots, or small cracks), normal wear and tear from regular use, incorrect assembly or installation, force majeure events (natural disasters, wars), or unauthorized modifications. Claims must be filed within the warranty period by contacting the manufacturer with photographic documentation of the defect. Warranty coverage differs for commercial use models.

Yes, the Como 4-180 is engineered for both residential and commercial applications. Its premium construction, durable ThermoWood® materials, three-level bench system, and generous capacity make it ideal for boutique spas, wellness centers, hospitality properties, vacation rentals, and commercial establishments seeking to offer premium sauna experiences. The design quality and professional-grade components ensure it can withstand frequent group use while maintaining aesthetic appeal and functionality. Contact sales regarding commercial-specific features, warranty terms, and heater packages optimized for business environments.

The Como 4-180 requires a stable, level floor prepared with a concrete foundation or driven piles to ensure structural integrity and prevent settling over time. The sauna requires a 220-240V hardwired connection with a dedicated breaker for the electric heater (specific amperage depends on your chosen heater model, typically 40-60 amps for 8-11kW heaters). A dedicated 120V connection is also recommended for LED lighting and control systems if you order those options. We strongly recommend confirming exact electrical specifications with a qualified electrician based on your heater selection before installation to ensure full compliance with local electrical codes and safety standards.

With proper care, the Como 4-180 can provide 20+ years of reliable performance thanks to its ThermoWood® construction and premium materials. Annual maintenance is recommended: apply UV-protective exterior varnish to maintain color and protect against moisture/weathering, and treat wooden benches with specialized sauna bench oils for smooth, long-lasting comfort across the multi-level seating. The tempered glass door and stainless hardware require only routine cleaning with mild soap and water. Ensure proper ventilation during and after use to manage humidity. Regular maintenance preserves the sauna’s structural integrity, appearance, and function throughout its lifetime of group use.
