ECS Custom Sauna Building Guide — 35-page PDF with CAD drawings and build sequence
The Problem

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.

Who This Is For

Written for the people building it.

For Contractors & Builders

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.

For DIY Owner-Builders

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.

What's Inside

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.

$1,500

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.

$99

Critical Specifications

Ceiling heights, vent placement, blocking dimensions, vapor barrier sequencing, furring spacing — the numbers no one publishes.

$99

"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.

$79

Material & Tool Requirements

What to source for each phase, where it goes, and what to avoid. Includes the materials supplied vs. not-supplied breakdown.

Questions We Get

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.
