The Viva 180 comfortably seats up to 4 people with intelligent internal spacing (68.6" W × 62.2" D × 82.7" H). The face-to-face bench design with backrests creates an intimate social experience perfect for couples or family sessions. Two adults can sit side-by-side on each bench, or you can arrange seating in a U-shape for conversation. The 5.8 m³ steam volume (205 cubic feet) is optimized for efficient heating while maintaining proper airflow and comfortable personal space.

The Viva 120 is a compact 1-person sauna (48.2" W × 53.5" D) ideal for solo relaxation and tight spaces, with 95.3 cubic feet steam volume. The Viva 180 is a spacious 4-person sauna (71.5" W × 70.9" D) designed for families or small groups, with 205 cubic feet steam volume. Choose the Viva 120 for personal daily wellness retreats or limited space. Choose the Viva 180 for shared experiences, families, or if you want flexibility for multiple users. Both deliver authentic leil experiences with identical ThermoWood® construction and engineering excellence.

The Viva 180 is designed for DIY-friendly modular assembly—most users complete installation in a single day with two people using basic tools. Prefabricated wall, floor, and ceiling panels align intuitively without requiring specialized equipment. The heavy tempered glass door (approximately 220 lbs) typically requires a third person for safe handling. Detailed assembly instructions are included. We recommend using trained specialists if you prefer professional installation, as they can handle the weight and complexity more efficiently.

The Viva 180 requires a 220–240V hardwired electrical connection with a dedicated breaker. Exact amperage and wire size depend on your chosen heater model (typically 9–11kW for this steam volume). We strongly recommend consulting with a licensed electrician before purchasing to confirm proper installation, circuit capacity, and compliance with local electrical codes. Dedicated 120V is also required for optional lighting and control accessories. Improper electrical installation can affect performance, safety, and warranty coverage.

The Viva 180 is compatible with electric heaters (9–11kW recommended for optimal heating) and wood-burning stoves (both sold separately). The 5.8 m³ steam volume requires adequate heater output for proper performance. Heaters are not included with the standard kit but available as optional add-ons. Popular recommendations include Harvia KIP 8kW, HUUM Drop 9, or HUUM Hive Mini models. Consult with a sauna specialist to select the best heater for your desired heat intensity, climate, and lifestyle preferences.

Yes, the Viva 180 is fully engineered for year-round outdoor use in all climates. The 40mm thick ThermoWood® construction provides exceptional thermal insulation and moisture resistance. The stave-built ceiling with EPDM rubber roof cover seals out rain, snow, and harsh UV exposure. We recommend applying an external UV-protective varnish treatment annually to maintain color and maximize durability. The sauna will endure severe cold winters and hot summers while maintaining structural integrity, thermal performance, and long-term durability.

The Viva 180's three-point ventilation system features intake beside the heater, exhaust under benches, and an adjustable drying vent in the upper corner. This engineered airflow distributes heat evenly, prevents cold spots, eliminates stale air, and reduces humidity buildup after sessions. The system creates the balanced temperature-humidity ratio that defines authentic leil steam—gentle yet deep warmth that allows longer, more comfortable sessions. The adjustable drying vent also helps dry interior surfaces post-session, extending sauna longevity.

The standard Viva 180 kit includes: prefabricated ThermoWood® wall/floor/ceiling panels, thermo-alder benches and backrests, bronze-tempered glass door, integrated ventilation system, EPDM roof membrane, assembly hardware, and installation manual. Sold separately: heater, heater controls, electrical installation, LED lighting kits, decorative hexagon DECO panels, sauna accessories (buckets, thermometers, ladles). Heater is the primary add-on—budget accordingly and choose based on your heating preferences and steam volume needs.

The Viva 180 is low-maintenance but benefits from annual care. Externally, apply UV-protective varnish to ThermoWood® to preserve color and protect against sun damage. Internally, treat benches with specialized sauna oil or wax to maintain a smooth finish and protect wood. Drainage (built-in floor drain with slight incline) should be checked periodically to ensure water flows freely. Wipe interior surfaces with a damp cloth after sessions and use the adjustable drying vent to dry surfaces. Regular annual maintenance significantly extends sauna lifespan and keeps it beautiful for decades.

The Viva 180 is designed for residential use—ideal for families, small groups, or couples seeking shared wellness experiences. If you're considering commercial applications, boutique spa use, or frequent multi-user rentals, warranty terms differ significantly and you should contact Leil directly. For commercial wellness centers, spa facilities, or high-use environments, Leil offers larger models better suited to demanding applications with appropriate commercial warranty provisions and specifications.
