Infrared Sauna Heaters

About

Infrared Sauna Heater Panels for DIY Builds & Conversions Infrared sauna heater panels warm your body directly with radiant heat rather than heating the air like a traditional electric heater. They're the core heating element in all infrared saunas, and they're what you need if you're building your own infrared sauna , converting an existing room or closet, or replacing panels in a pre-built unit. We carry individual panels and complete panel packages from Finnmark Designs in both 120V and 240V configurations. Not sure how many panels you need? Our Infrared Panel Calculator will tell you based on your room dimensions. Carbon Fiber vs. Ceramic Panels Carbon Fiber Panels — The most popular choice for DIY infrared sauna builds. Carbon fiber heaters produce a broad, even distribution of far infrared (FIR) wavelengths across a large surface area. They run at lower surface temperatures than ceramic, which means more comfortable radiant heat and longer lifespan. Carbon panels are thin and lightweight, making them easy to mount on walls and ceilings. Ceramic Panels — Ceramic infrared heaters produce a more focused, intense heat from a smaller surface area. They reach higher surface temperatures than carbon fiber and emit a narrower infrared spectrum. Ceramic panels are a good choice when you want concentrated heat in a specific spot or have limited wall space. They're also commonly used as supplemental heaters in hybrid sauna builds . Voltage Options 120V Panels — Plug into a standard household outlet. Best for smaller builds (closet conversions, 1–2 person saunas) or situations where running a dedicated circuit isn't practical. Our 120V panel packages include a mechanical controller with timer and cover up to 120 cubic feet. See our 120V sauna heater guide for details. 240V Panels — For larger builds that need more total wattage. Requires a dedicated circuit installed by a licensed electrician. Pair with a digital controller for precise temperature and timer settings.
