FAQ

Questions before you build?

The questions I get asked the most.

Is the heater included? What does it cost?
+
No — the build cost doesn't include the heater. You've got two options. A 110V plug-in heater (around $150) runs on a standard household outlet, no electrician needed. Or for faster heat-up and higher temps, go with a 240V heater. I now sell the Harvia KIP (from $954, free shipping), and the 4.5 kW is the right size for this build. It needs a dedicated 240V circuit installed by a licensed electrician.
What's the total cost to build?
+
About $2,033 all-in (materials) — Here's roughly where it goes:
  • ✓Cedar [$675]
  • ✓Framing lumber [$390]
  • ✓Exterior (roof,siding) — [$294]
  • ✓Insulation, vapor barrier & foil tape — [$154]
  • ✓ Miscellaous & - [$394]
  • ✓Hardware, screws, hinges, stain & oil — [$127]
How big is the sauna? Can I change the size?
+
The plan builds to roughly 48"W × 39"L × 75"H interior (49"W × 50"L × 84"H exterior) — comfortable for two. The framing is universal, so you can scale it up or down to fit your space.
Do I need building experience?
+
These plans are written for someone who's comfortable with basic building — measuring, cutting, driving screws. If you've framed anything before, you'll be fine. Want every step shown on video with my direct help? That's the full course.
What tools do I need?
+
Basic stuff most people already have or can borrow: a saw, a drill, a stapler, metal shears, and a 4" hole drill bit. That's really it. No specialty woodworking gear.
Will it work in all climates?
+
Yes. People have built these in cold, hot,and rainy climates. The insulation, vapor barrier, and sealing will keep all elements out and the heat in.
What exactly do I get when I buy?
+
Instant access after checkout, and you keep it for good. Here's everything that comes with it:
  • ✓Detailed written instructions for every step
  • ✓Sauna-specific insights you won't find in free plans
  • ✓Full materials list, cut list, and heater recommendations — and much more

Sauna-Specific Details

Ventilation sizing and placement, insulation & vapor barrier, proper bench heights, and heater safety clearances — the details that separate a sauna from a shed.

Lifetime Updates

Pay once, own it forever. Every revision and improvement to the plans is included at no extra cost.

Free plans can frame you a box. They won't tell you where the vents go or how to size them, how high the benches should sit, or how close they can safely be to the heater. Get those wrong and you've built a cedar shed that molds out in a year — not a sauna. That's the knowledge and experience these plans are built around.

A professional outdoor sauna.
Built to spec.

Hey, I'm Ben 👋
Nice to meet you.

I'm not a contractor — I started building these in my backyard in South Florida as a hobby, and now I build custom saunas for clients across the state.

These are the exact plans I use on those paid builds.
