The Leil VIVA 210 is a three-person outdoor traditional sauna designed to provide more shoulder room and the option to recline while maintaining a relatively compact footprint. It is constructed from 40 mm ThermoWood® elements and includes thermo-alder seating, a bronze tempered-glass door, an EPDM-covered roof, and three-point gravity ventilation.

The standard package includes the sauna cabin only. Heater, controls, sauna stones, lighting, and accessories are selected separately.

ThermoWood® Characteristics

ThermoWood® is modified with controlled heat and steam without adding chemical wood preservatives during the thermal-modification process.

Relevant characteristics include:

• Reduced equilibrium moisture content
• Reduced moisture absorption
• Improved dimensional stability
• Reduced swelling and shrinking
• Reduced warping and twisting
• Reduced resin release
• Consistent warm coloration
• Suitability for changing heat and humidity when maintained correctly

Thermally modified wood remains a natural material and still requires annual inspection and treatment.

Heating Options

The current Muskoka configuration offers two electric-heater families:

• HUUM DROP 7.5 kW
• Saunum Air 7

Neither heater is included in the base cabin price. The selected heater must be listed on the approved estimate with its controller, stones, sensors, safety accessories, and electrical requirements.

Leil also identifies the VIVA series as compatible with appropriately designed wood-fired heating, although a wood-fired package is not presently shown among the linked Muskoka product options.

Door and Glazing

• Door material: Tempered safety glass
• Glass color: Bronze tint
• Door hardware: Black metal
• Handle: Premium sauna-door handle
• Timber construction above the glazing
• Door orientation: Confirm from final production drawings

The additional ThermoWood® above the glazing helps limit the loss of accumulated warm air and steam when the door is opened.

Roof Construction

• Forty-millimetre ThermoWood® ceiling
• Exterior EPDM roof covering
• Designed for outdoor moisture protection
• EPDM edges, seams, and penetrations must be installed correctly
• Roof must shed water away from the cabin
• Local snow, wind, rainfall, and anchoring requirements must be evaluated

The supplied roof construction does not eliminate the need for locally required structural or building-code review.

This is designed to:

• Reduce vertical temperature stratification
• Improve temperature consistency between the upper and lower body
• Move air through the cabin
• Allow adjustment of climate intensity
• Support post-use drying circulation
• Preserve traditional water-over-stones steam

• Stones must be loaded according to heater instructions
• Stones must not be packed tightly around heating elements
• Only suitable sauna water should be applied
• Cracked or deteriorated stones should be replaced
