What Makes Us Different

Authentic Finnish Design

Our plans follow the Finnish "Law of Löyly": your feet must be higher than the heater stones for proper heat distribution. Most DIY sauna plans have benches that are too low, resulting in cold feet and poor steam circulation.

Proper Ventilation

A functioning sauna requires a specific airflow system, not just an open vent. Our plans include gravitational ventilation design that keeps CO2 levels low and the air fresh.

Professional Architect

Designed by a full-time architect at Rantanen Architects in Finland, a firm that designs homes and commercial buildings. This isn't a hobby project—it's professional-grade architectural work.

Designed for Durability

Our plans include proper floor sloping and drainage because a real Finnish sauna is a wet room. This ensures the structure lasts for decades without rot or mold issues.

Frequently Asked Questions

Do I need to be a professional builder?

The plans are professional-grade architectural drawings that are clear and logical. Experienced builders can work directly from them. The Complete Builder Set (coming soon) will include step-by-step guidance for DIYers.

What heater size do I need?

The sauna is optimized for a 9kW electric heater or an equivalent wood-burning stove. Never compromise on stone capacity—the heater needs massive stones for soft, long-lasting steam.

Is there a money-back guarantee?

Yes. We offer a 7-day money-back guarantee. If you're not satisfied with the plans, contact us within 7 days for a full refund.

How do I get the plans after purchase?

Plans are delivered as instant digital downloads. You'll receive access immediately after purchase.
