Why You'll Love It

Spacious 5–6 Person Capacity

The MW20 is designed for 5–6 people, making it the largest sauna in the Mande MW Series and an ideal choice for shared sauna sessions.

Premium ThermoWood Construction

The cabin is built from ThermoWood®, a thermally modified wood engineered for enhanced dimensional stability and outdoor durability.

Handcrafted in Lithuania

The MW20 is manufactured by Mande Wood in Lithuania, bringing European sauna craftsmanship and traditional woodworking expertise to the design.

1.7-Inch ThermoWood Walls

The sauna features approximately 1.7-inch ThermoWood wall construction, providing substantial insulated wood-panel construction for an outdoor sauna environment.

Rounded Cube Architecture

The MW20 uses a distinctive rounded-cube outdoor design, giving it a modern architectural appearance while preserving the practical layout of a traditional sauna.

Panoramic Tempered-Glass Windows

Large tempered-glass windows provide a wide visual connection to the surrounding outdoor space while complementing the full-width glass entrance.

Full-Width Tempered-Glass Door

The MW20 includes a substantial tempered-glass door with an approximate 25.6-inch door opening width and 69.7-inch door height.

Two-Level ThermoWood Benches

The sauna includes two-level ThermoWood benches designed with a deeper upper platform that can be used in a sunbed-style configuration.

Sunbed-Style Upper Bench

The upper bench measures approximately 64 inches wide by 23.6 inches deep, providing a large surface for sitting or stretching out during a sauna session.

Integrated Under-Bench LED Lighting

Integrated LED lighting beneath the benches adds a subtle modern accent and provides soft illumination within the cabin.

Passive Ventilation System

The MW20 includes integrated passive ventilation, helping manage airflow within the sauna.

Weather-Resistant Bituminous Roof

The roof uses a bituminous shingle system, providing a weather-resistant roof covering designed for outdoor installation.

Stainless-Steel Hardware

Precision Joinery

Mande's construction incorporates precision joinery intended to support long-term structural stability and an elevated finished appearance.

Designed for Year-Round Outdoor Use

The MW20 is engineered as an outdoor sauna for year-round use, with ThermoWood construction and a weather-resistant roof system.

Multiple Heater Choices

Choose from available heater configurations to create either a convenient electric sauna or a more traditional wood-burning experience. Current Patio Elegance listings show Harvia KIP 8.0kW electric heater options and a Harvia M3 wood-burning heater with full chimney set.

Electric Heater with Wi-Fi Option

Patio Elegance's current MW20 selector includes an 8.0kW Harvia KIP with Wi-Fi controller as one available configuration.

Traditional Wood-Burning Option

For customers who prefer a traditional wood-fired sauna setup, the MW20 can be configured with the Harvia M3 wood-burning heater and full chimney kit.

Typical Electric Heat-Up Time

Matching Patio Elegance-related specifications indicate a typical electric heat-up time of approximately 35–45 minutes, depending on conditions and heater configuration.

Designed for Your Wellness Edge Frontier Space

The Mande MW20 is designed for customers who want more than a compact backyard sauna. With space for 5–6 people, expansive benches, panoramic glazing, and premium ThermoWood construction, it can become the centerpiece of an outdoor wellness environment.

Place it near a pool, beside a cold plunge, on a dedicated patio, or within a landscaped backyard retreat. The large footprint allows room for shared sessions while the architectural cube design gives the installation a polished, contemporary look.

At Wellness Edge Frontier, we believe premium wellness equipment should be as thoughtfully designed as the space around it.

Installation & Delivery

The MW20 is delivered as a flat-pack kit and requires on-site assembly. Large structural components are manufactured before shipment to simplify assembly while retaining the finished sauna's structural design.

The assembled sauna measures approximately 83.1" wide × 78.7" deep × 83.5" high, and the listed assembled weight is approximately 1,565 lbs.

Matching listings identify shipping dimensions of approximately 6 ft 7 in × 3 ft 9 in × 3 ft 9 in and a shipping weight of approximately 1,565 lbs.

A suitable foundation or base, site preparation, and access for delivery and assembly are the purchaser's responsibility. Professional installation is recommended, and electric heater connections must be completed by a licensed electrician.

Patio Elegance-related listings specify LTL freight with curbside delivery, meaning customers should plan for the sauna to be moved from the delivery point to the prepared installation location.

Outdoor Installation Considerations

The MW20 is engineered for outdoor use, but the installation location should still provide:

• A level, properly prepared foundation
• Adequate drainage around the structure
• Sufficient access for assembly and maintenance
• Safe clearance around the heater and chimney where applicable
• Appropriate electrical service for electric heater configurations

For wood-burning configurations, the chimney system must be installed according to manufacturer instructions and applicable local regulations.

Warranty

Current matching Mande MW20 listings identify a 5-year limited residential structural warranty covering the sauna structure under the stated warranty terms.

Because warranty coverage can vary depending on the seller and selected heater package, the warranty associated with the exact Wellness Edge Frontier SKU should be confirmed before publication.
