At Harbor Saunas, we believe that great design is rooted in both history and function. The Iska Sauna is our latest creation—a compact yet powerful retreat inspired by the ice fishing huts and warming shelters that have long provided refuge in the frigid winters of the Northeast and Scandinavia.

The Iska blends time-honored materials with a modern approach to sauna design, offering a warm escape in the coldest months. Featuring an expansive glass window, the Iska invites you to experience heat and restoration while staying connected to the natural beauty that surrounds you.

For centuries, ice fishing huts and warming structures have provided essential shelter in the harshest winter conditions. These compact, efficient buildings are designed to:

• Retain heat effectively, using high-insulation materials and smart ventilation.
• Withstand extreme weather, from freezing winds to heavy snowfall.
• Offer a place of refuge, continuing the Nordic tradition of gathering around warmth.

The Iska Sauna takes these same principles and refines them into a modern sauna experience, built to endure wherever you place it—whether nestled in a snowy forest, perched on a rocky coastline, or overlooking a frozen lake.

The Iska is designed for intimate yet immersive sauna sessions, comfortably seating 2-4 people.

Key Features:

• Exterior Dimensions: 7’6” L x 7’0” W x 9'4” H
• Exterior: Knotted select cedar, finished with Black Viking Linseed Oil for superior weather protection
• Interior Dimensions: 4’4” L x 6’3” W x 6'11” H
• Interior: Knotted select cedar benches and walls, designed for comfort and durability
• Expansive Glass Window: Creates a sense of openness while maintaining heat efficiency
• Exceptional Heat Retention: Insulated with ROCKWOOL and a vapor barrier
• Passive Ventilation System: Fresh air enters from the floor and exits through a sliding vent under the top bench
• Antique Brass Fixtures: Aged to perfection, inspired by the maritime heritage of the Northeast

Designed to age beautifully over time, the Iska will naturally adapt to its environment, developing a rich patina that enhances its character and durability.

The Iska Sauna is heated by the HUUM CLIFF 6kW electric heater, a Scandinavian-designed element that delivers an exceptional sauna experience.

Why the HUUM CLIFF 6kW Heater?

• Minimalist design that complements the Iska’s aesthetic
• Fast heat-up time, ideal for efficient sauna sessions
• High stone capacity, allowing for gentle, even heat and superior steam
• WiFi compatibility, enabling remote preheating for convenience

This heater ensures that, despite its compact footprint, the Iska produces the intense, deep heat expected of a traditional sauna.

TThe Iska Sauna comes standard with cedar cladding finished in Black Viking Linseed Oil, a centuries-old Scandinavian treatment known for its ability to withstand harsh coastal and winter climates.

Why Black Viking Linseed Oil?

• Deep penetration into the wood, enhancing durability and water resistance
• Allows the wood to breathe, preventing cracking or peeling
• Develops a rich, natural patina over time, blending seamlessly with the landscape
• Eco-friendly and natural, free of synthetic additives

This finish not only protects against the elements, but also ensures that the Iska ages with grace and integrity over the decades.

The Iska is a natural extension of the Harbor Saunas portfolio, offering a compact, efficient alternative to our flagship Lighthouse Sauna. Built for those who want a high-performance sauna in a smaller footprint, the Iska delivers true Scandinavian heat while maintaining the timeless craftsmanship and durability that define our work.

With its historical inspiration, premium materials, and exceptional design, the Iska is built to provide warmth and restoration for years to come—a true retreat, no matter the season.
