What is a custom infrared sauna?

A cabin built to your room's exact dimensions with heater placement, low-EMF wiring, cedar, bench layout and optional 660/850nm red light engineered for seated geometry. See home guide.

What heater type is best?

VantaWave or SoloCarbon for engineered custom coverage; carbon for value; ceramic for hotter directional; halogen/full-spectrum for intense top heat. See heaters.

What EMF level should I look for?

Under 3 mG at seated position operating. SaunaCloud ~0.20 mG avg; budget 5–100 mG. Demand seated readings + ETL. See EMF. Full document list: buyer's checklist.

Does red light in a sauna work?

Only at 2–6 in. Bench-embedded = therapy; wall strips at 24 in.+ = ambient. See red light.

Can I run red light without heat?

Yes on SaunaCloud-class integrated systems — cool/quiet red-only mode or combined with heat.

What wood is best?

Clear Western Red Cedar. Avoid plywood/particle board inside. See wood.

4×4 (1-person) to 5×6+ (3–5); 120V/20A small, 240V/30–60A multi-person, NEC 424. See installation.

Indoor or outdoor?

Indoor for efficiency and electronics life; outdoor only purpose-built weather-sealed (Atlas Outdoor). See indoor vs outdoor.

What about commercial use?

Reinforced framing, serviceable power, ADA options, commercial warranty. See commercial.

How often and how long?

Is it safe?

Generally well-tolerated; avoid with unstable cardiac conditions, pregnancy, or heat-sensitive meds without clearance. Hydrate, avoid alcohol. Educational only.

Custom or prefab?

Custom for daily use + exact fit + real red light; prefab for budget/speed. See custom vs prefab.
