Everything after the heater chart: the circuit, the ventilation, the wall, the wood and the clearances
Every sauna retailer publishes a heater sizing chart, because publishing it sells heaters. None of them publish what comes next — and that is where a home sauna build actually goes wrong. This is the branch circuit (breaker, conductor, and the voltage drop that quietly starves an outdoor sauna wired correctly on ampacity alone), the ventilation scheme and where each opening goes, the wall build-up in assembly order with what fails at each layer, the timber table including which species must never touch a bench, and the clearances to reserve before you have even chosen a heater model. 8 pages, printable, ending in a fill-in build record and materials take-off you can hand to an electrician and a timber merchant. Advisory: your heater's manual and your local code govern the install.
What’s inside
Branch circuit by heater size: draw, breaker and minimum copper conductor
Voltage drop by distance from the panel, and when to upsize the cable
Ventilation sized from air changes, with the inlet and outlet for your room
Where each opening goes — and the placement mistake that makes a sauna feel stuffy
The wall build-up in assembly order, and how each layer fails
Eight things never to put in a sauna, and what to use instead
Ten timbers rated for walls and for benches, with the ones that burn skin
Heater clearances to reserve before you choose a model, and the stone specification
Bench heights derived from your ceiling, not from a catalogue
The build sequence, and the three decisions to make before cutting anything
What a session actually costs — heat-up, duty cycle, and why the usual rule of thumb is wrong in both directions
