Sauna Builder
The Sauna Builder
Build your room exactly the way you want it — cedar, benches, glass, heater, controls and light — and watch the price update as you go. Every part is a real, in-stock component from the brands we carry, not a placeholder.
Cost breakdown
Line by line, exactly what your current configuration costs. Nothing is marked up for being part of a build — these are the same prices you would pay buying each part on its own.

Manuals & instructions
Everything you need before the first board goes up. Read the build guide first — it covers framing, vapor barrier, batten spacing and bench heights before you buy anything.

- The cedar package is an interior liner kit. It finishes the inside of a room you have already framed — it is not a freestanding building.
- Wall boards run horizontally by default. Tell us at checkout if you want them vertical so the lengths are milled to suit.
- Bench lumber is priced per linear foot. The quantity above is calculated from your room size and layout and already includes a 10% cutting allowance.
- Heater kW is a recommendation based on room volume at the height you selected. Glass adds heat loss — every square foot of glass adds roughly the load of an extra 2.5 cubic feet of room.
- All heater wiring must be completed by a licensed electrician to local code. We do not provide electrical design.
- Freight is quoted after the build is confirmed. Long lumber ships by LTL freight and needs curbside access.
