Most home saunas are built wrong.
Saunas live in one of the most hostile environments in a home — sustained 180°+ heat, cycling humidity, constant thermal movement. The details that matter aren't what most contractors expect.
Wrong Ventilation
Bathers feel stuffy. Wood holds moisture. Cladding starts breaking down years before it should.
Wrong Vapor Barrier
One unsealed wire penetration becomes the air leak that bleeds heat and pulls moisture into the wall cavity.
Wrong Wood & Furring
Skip the air gap behind the cladding and the wood rots from behind in seven years instead of lasting twenty-five.
Written for the people building it.
Walk onto your first sauna like you've already done a dozen.
Saunas are their own discipline. Most contractors learn by trial and error — usually on a client's dime. This is the reference that gets you to a professional install on your first project. Every spec, every sequence, every detail.
Running your own build. Get it right the first time.
If you're framing, wiring, and finishing this room yourself, this is the document that gets you to a professional result without the trial-and-error tax most owner-builders pay. Every phase sequenced, every dimension specified, every decision explained.
Here's exactly what you get.
35 pages. 18 detailed CAD drawings. 14 build phases — sequenced in the order the work actually happens.
18 Detailed CAD Diagrams
Isometric drawings with full callouts and dimensions covering framing, vents, blocking, electrical rough-in, vapor barrier, cladding, benches, backrests, duckboard, and door installation.
Phase-by-Phase Build Sequence
Framing through finish, in the exact order each phase happens on a real install — so nothing gets done out of order.
Critical Specifications
Ceiling heights, vent placement, blocking dimensions, vapor barrier sequencing, furring spacing — the numbers no one publishes.
"Why This Matters" Companion Pages
Plain-English explanations of the engineering rationale behind each spec — so you know what you're looking at, not just what to do.
Material & Tool Requirements
What to source for each phase, where it goes, and what to avoid. Includes the materials supplied vs. not-supplied breakdown.
Built like the rooms it teaches you to build.
Every page is designed to be referenced on a job site, not just read once. CAD diagrams alongside step-by-step instructions. "Why This Matters" callouts that explain the reasoning. Hardware and material requirements specified per phase. This is a working document.

Common Questions.
No. The guide teaches the methodology — what good work looks like and how to execute it. If you'd rather have specialists handle every technical decision and source the materials, our 30-day material credit means buying the guide costs you nothing once you order materials from us.
Yes. The guide is written assuming the reader is a competent contractor — someone who can frame a wall, run electrical, install tile. If they build high-end bathrooms, they can build a sauna with this guide. Every phase is sequenced, every detail specified, every CAD drawing dimensioned.
A high-resolution 35-page PDF, instantly downloadable after purchase. Print-ready for job-site reference. Yours to keep forever.
Due to the digital nature of the product, all sales are final. However, if you order any sauna materials from us within 30 days of purchasing the guide — even a single heater — we credit the full $149 guide cost against your material order. The guide effectively becomes free.
The guide works anywhere. The methodology is universal — these specs aren't location-dependent. ECS supplies materials nationwide if you'd like premium components shipped to your job site, and the 30-day material credit applies anywhere in the continental US.
