A comprehensive ebook that walks you through every phase of sauna construction — from site selection and framing to insulation, vapor barriers, ventilation, heater sizing, and interior finishing. Written from real build experience, not generic advice.
This is the guide we wish existed when we started building saunas. It covers the full scope of a sauna build — the decisions that matter, the mistakes that are expensive, and the details that most guides skip. Whether you're building yourself or handing a plan to a contractor, this gives you the knowledge to make good decisions at every stage. The guide is based on real projects we've designed and built in Tahoe, Reno, the Pacific Northwest, and remote designs across the country. It's a PDF — buy it, download it, and start reading immediately.
Everything you need to understand before you start building — or before you hire someone to build for you.

Your plan will be delivered to your email within 24 hours of purchase.
Wall framing, floor joists, roof structure, and foundation options. What lumber to use, how to size it, and how to handle the unique structural requirements of a sauna.
Which insulation types work for saunas (and which don't), how to install a vapor barrier correctly, and why getting this wrong is the most expensive mistake you can make.
Intake and exhaust placement, mechanical vs. passive ventilation, and how to size your airflow for the room. Bad ventilation ruins the sauna experience — this section makes sure you get it right.
Electric vs. wood-fired, how to calculate the right kW for your room size, wiring requirements, clearance distances, and control options including WiFi-enabled heaters.
Cedar vs. other wood species, tongue-and-groove installation, bench design and construction, lighting, flooring options, and door selection.
What to buy, where to source it, and how to avoid overpaying. Covers lumber, fasteners, insulation, vapor barrier, siding, heaters, and electrical components.
The errors we see most often — wrong vapor barrier placement, undersized heaters, poor ventilation, and structural shortcuts that lead to moisture damage. Learn from other people's builds, not your own.
DIY builders who want to understand every step before they start cutting lumber. Homeowners hiring a contractor who want to know enough to ask the right questions and catch mistakes. Anyone in the research phase who wants a single, thorough resource instead of piecing together forum posts and YouTube videos.
The guide is a PDF ebook — $47, instant download after purchase. No subscriptions, no accounts to create, no waiting. Buy it and it's yours. Read it on your phone, tablet, or laptop. Print it out and bring it to the job site.
