DIY Sauna Plans

A lot of people that watched my DIY Backyard Sauna Sauna Series on YouTube asked me if they could purchase the plans. So I put two sets together that cover everything you need to make the exact same Sauna. Here they are:

6′×8′ Outdoor Sauna — Framing Plans

These are the plans I drew from building a 6′×8′ cedar sauna on my back deck. Every dimension, every cut, pulled from the as-built measurements, not generic templates.

What’s in the 7-page PDF:

• Cover sheet with key specs at a glance
• Floor framing plan — sleeper layout @ 10″ O.C., cedar deck direction, with substitution notes for non-deck build
• Back wall elevation — 96″×88″, with a California-corner detail (single corner stud + backing block) for less thermal bridging and more insulation cavity
• Front wall elevation — door & window rough openings precisely dimensioned, with kings/jacks/headers/cripples all called out
• Side wall elevation — slope-cut studs with exact cut lengths at every position (88″ back tapering to 79″ front)
• Roof framing plan — rafters @ 16″ O.C. on edge + outer 2×4 wrap for the eave overhang
• Materials & cut list — every 2×4, every fastener, with real prices from my build

You can watch how I framed this sauna using these plans step by step in this video here.

6′×8′ Outdoor Sauna Interior & Finish Plans

Phase 2 of the build, picking up where the framing leaves off. These are the actual interior decisions from my own sauna: wall buildup, bench geometry, heater placement, vent positions, all drawn from the as-built measurements.

What’s in the 8-page PDF:

• Cover sheet with key materials at a glance
• Wall buildup section detail — cedar T&G → 1×2 furring (3/4″ air gap) → foil vapor barrier → R-15 Rockwool → 2×4 stud → OSB → Tyvek → SmartSide
• Interior plan view — bench positions, heater corner, vent placement, door swing
• Back wall interior elevation — 17 cedar boards + top exhaust vent dimensioned
• Front wall interior elevation — door + window mirrored from exterior, intake vent at heater wall
• Side wall interior elevation — 16 + 1 angled cedar board, heater placement with clearances, thermometer position, electrical note
• Bench detail — cross-section + plan: top bench (8’×20″×44″H) + bottom bench (8’×15″×26″H) offset forward, joists 12″ O.C., 4″ cedar slats with 1″ gaps
• Materials & cut list — cedar counts per wall, insulation, vapor barrier, furring, vents, heater, bench lumber

You can also buy both PDFs together: 15 pages of dimensioned drawings, materials lists, and build-tested decisions for a 6′×8′ outdoor cedar sauna. Framing through finish, drawn from an actual build on a backyard deck. Prices for lumber and hardware documented with real prices from my exact build.
