Overview

The Leil VIVA 250 is a four-person outdoor traditional sauna manufactured in Estonia. It is the most spacious and tallest model in the VIVA collection, providing an approximately 304-cubic-foot interior with elevated two-level seating.

The cabin is constructed from 40 mm ThermoWood® elements and includes thermo-alder seating, a bronze tempered-glass door, an EPDM-protected roof, and three-point gravity ventilation. Electric and wood-fired heater configurations are supported, but the linked Muskoka cabin package does not include a heater, controls, stones, or lighting as standard.

• Forty-millimetre solid wall elements
• Vertical architectural bars across the front elevation
• Bronze-tinted glass
• Black exterior hardware

ThermoWood® Characteristics

ThermoWood® is modified using controlled heat and steam rather than chemical preservatives. The process reduces equilibrium moisture content and improves dimensional stability in changing heat and humidity.

Relevant characteristics include:

• Reduced moisture absorption
• Improved dimensional stability
• Reduced swelling and shrinking
• Greater resistance to warping and twisting
• Reduced resin release
• Consistent warm coloration
• No added chemical wood preservatives during thermal modification

ThermoWood® still requires regular inspection and exterior maintenance.

Door and Glazing

• Door material: Tempered safety glass
• Glass color: Bronze tint
• Published glass thickness: Approximately 8 mm
• Door hardware: Black
• Handle: Premium sauna-door handle
• Front assembly: Door and adjacent glazed sections
• Timber buffer installed above the glazing

The additional timber above the glazed section helps retain more warm air and steam when the door is opened.

Roof Construction

• Forty-millimetre ThermoWood® ceiling
• Timber roof assembled from individual elements
• Exterior EPDM membrane
• Designed for outdoor weather protection
• Roof must be installed with the required slope and detailing
• EPDM seams, edges, and penetrations must be completed according to the installation instructions
• Snow, wind, and rain exposure must be evaluated for the specific site

The roof does not replace any locally required engineering, anchoring, snow-load, wind-load, or building-code review.

The VIVA 250 supports traditional sauna heating using either:

• A properly sized electric sauna heater, or
• A compatible wood-fired sauna stove

The linked cabin package does not include either heating option. Heater selection must account for:

• Approximately 304-cubic-foot room volume
• Tempered-glass area
• Outdoor ambient conditions
• Desired warm-up performance
• Required safety clearances
• Available electrical service
• Chimney feasibility
• Local permits and code requirements

When an electric heater is selected, the final package must include:

• Appropriately sized electric sauna heater
• Compatible control system
• Required temperature sensor
• Required door sensor when applicable
• Manufacturer-approved sauna stones
• Heater guard where required
• Electrical documentation
• Correct ventilation layout

The manufacturer and linked seller do not identify a standard electric heater in the cabin price. No heater model, power rating, Wi-Fi control, or stone quantity should be advertised as included until it appears on the approved estimate.

Electrical requirements are determined by the selected heater and lighting package.

Potential requirements include:

• Dedicated heater circuit
• Heater-specific voltage and phase
• Properly sized breaker
• Correct conductor size and temperature rating
• Equipment grounding
• Local disconnect where required
• Separate lighting supply
• Weather-appropriate exterior routing and enclosures
• Licensed-electrician installation

The electrical service must not be designed until the exact heater, controller, lighting package, supply voltage, and current installation manual have been confirmed.

A wood-fired installation may require:

• Properly sized wood-burning sauna stove
• Manufacturer-approved sauna stones
• Chimney and flue system
• Ceiling and roof penetration components
• Heat shields
• Noncombustible wall protection
• Noncombustible floor or hearth protection
• Spark-arresting components where required
• Required clearances to combustible materials
• Combustion-air provisions
• Local building and fire approvals

The heater and complete chimney package must be designed together. A generic chimney kit should not be substituted without confirming compatibility.

• Traditional high-temperature sauna
• Water-over-stones steam
• Elevated seating intended to improve body placement within the warm-air zone
• Three-point ventilation supports fresh-air movement
• Timber buffer above the glazing supports heat and steam retention
• Warm-up time depends on heater output, outdoor temperature, wind, glazing, ventilation, and stone quantity
• Final operating-temperature range depends on the selected heater and control

No fixed warm-up time or maximum temperature should be published without the selected heater’s documentation.

Standard Cabin

• No electrical lighting confirmed as standard in the linked cabin package

Optional LED Package

Available lighting positions may include:

• Under the bench
• Above the backrest
• Above and below the backrest
• Dimmable operation
• Transformer
• Cabling
• Dimmer switch
• Installation enclosure

Lighting color, output, voltage, control type, and included components must be confirmed on the final estimate.

Chromotherapy is not included unless a separate color-lighting package is specifically selected.

The VIVA 250 uses three-point gravity ventilation:

• Fresh-air intake beside the heater
• Exhaust opening beneath the benches
• Adjustable drying vent in the upper corner

This arrangement is intended to:

• Introduce fresh air near the heat source
• Move warmed air through the occupied area
• Support more consistent cabin conditions
• Release retained heat and moisture after use
• Help the timber interior dry between sessions

Vent locations may require adjustment to comply with the selected heater’s instructions. Heater-manufacturer requirements take precedence when they differ from the generic cabin layout.

Leil saunas use integrated floor-drainage provisions with a slightly inclined floor directing water toward the drain.

The site must provide:

• A suitable drainage destination
• Freeze-conscious piping where applicable
• Proper slope
• Code-compliant discharge
• Protection against water backing into the cabin
• Access for inspection and maintenance

The drain must not be treated as a substitute for a properly prepared waterproof foundation or surrounding site drainage.

The client must provide:

• Solid, level foundation
• Foundation sized to the approved production drawings
• Sufficient structural capacity for the approximately 1,874-pound cabin, heater, stones, occupants, and environmental loads
• Positive drainage away from the sauna
• Protection from standing water
• Required anchoring
• Safe walking access
• Electrical or chimney provisions
• Required setbacks
• Installation and service clearances
• Local permits and approvals

Suitable foundations may include an engineered concrete slab, properly designed piers, or another approved structural platform.

• Supplied as a modular sauna kit
• Detailed installation instructions included
• Professional assembly recommended
• Multiple installers required
• Foundation must be completed and verified before assembly
• EPDM roof installation must be weather-tight
• Glass must be handled with appropriate lifting equipment
• Door alignment must be completed after the cabin is level
• Heater and controls installed according to their separate manuals
• Licensed electrician required for electric heating
• Qualified chimney or hearth professional recommended for wood-fired heating
• Local code and authority requirements apply

Leil permits self-assembly but recommends trained specialists with appropriate tools and experience.
