About Our Custom Saunas

A custom sauna from Northern Steam is the closest you can get to owning a truly one-of-a-kind wellness space. Built by hand in Cokato, MN, each custom project is shaped around your vision — from layout and materials to windows, heat source, lighting, and exterior finishes. Whether you want a minimalist Scandinavian retreat, a warm cabin-style sauna, a lakeside escape, or a modern architectural statement piece, we design and build it from the ground up.

We combine Finnish sauna tradition with Minnesota craftsmanship to deliver saunas that are functional, beautiful, and built for everyday use. Every board, joint, and detail is handcrafted by our small team, ensuring uncompromising quality and long-term durability. If you want something beyond a standard model — something made exactly the way you imagine — a Northern Steam custom build is the answer.

What You Can Customize

Unlike our standard Tuli and Superior models, custom builds allow you to choose nearly every detail, including:

• Dimensions & Layout: steam room, lounge, dressing room, porch, windows, partition walls
• Interior Woods: clear cedar, clear aspen, thermally modified ash, premium species
• Exterior Siding: cedar, LP, Nichiha, metal, or mixed-material designs
• Roofing: standing-seam metal, black metal, or premium architectural options
• Heat Source: IKI wood-fired or IKI electric stoves (various models)
• Windows & Doors: picture windows, awning, transom, full-length glass, custom doors
• Benching: multi-tier, floating benches, clear wood upgrades
• Lighting: under-bench LEDs, sconce lighting, strip lights, soffit lighting, dimmable can lights
• Stove Surround: metal, tile, concrete, custom black metal, or designer heat shields
• Flooring: cedar duckboards, thermally modified ash, composite options
• Exterior Trim & Accents: grain-matched doors, stained trim, modern profiles

If you can picture it, we can build it.
