This is where Tahoe Sauna Company started — my backyard sauna build.
I'd been using the gym sauna for years and had gotten tired of the small, crowded space. Eventually I decided to build my own. I was not a builder.
So I spent a few months researching Finnish sauna design principles before ordering a pallet of materials from Home Depot. Then I figured it out as I went.
The structure: compacted gravel base, concrete deck blocks, pressure treated 2x6 floor framing with OSB on top, 2x4 stud walls, shed roof with proper shingles, house wrap, fiberglass insulation, t1-11 siding, and windows. Inside: aluminum foil v***r barrier with taped seams, air gap, cedar shiplap wall panels, redwood 2x4 benches, tile floor, and a Harvia electric stove.
Was it perfect? Not at all. Would I change a handful of things I did? Yes. But it's been running through Tahoe winters for 5+ years without any real issues.
The three things that actually matter:
1. Build it durable — weather-resistant structure, proper roof, good siding
2. Insulate it well — it should hit 170–200°F and hold it
3. Build it tall enough for two or three bench tiers so users sit in the hot zone above the stove
Get those three right and you'll have a good sauna. Want a great sauna? Reach out to us and we're happy to answer any questions about your future sauna.
