Transform any space into a high-performance infrared sauna with the Finnmark Spectrum Carbon™ Heater Panel Kit. Designed for both new construction and retrofit installations, these long-wave, full-body carbon infrared heaters provide deep therapeutic warmth to promote pain relief, muscle recovery, improved circulation, and relaxation. The system offers quick surface-mount installation and includes a WiFi-enabled V2 digital controller with SmartLife app integration for total session control.
Each panel features a zero-slat front design that maximizes infrared exposure area, paired with high-emissivity surface materials (.997) for maximum heat efficiency. Certified low EMF (0.5893mG) and built with Canadian cedar frames, this system is as safe and durable as it is effective.
Note on Compatibility
This heater system is not compatible with traditional electric sauna heaters. For a hybrid infrared + traditional sauna, please see the Spectrum+™ Ceramic Heater Kit.
Installation
Spectrum Carbon™ panels are quickly installed using the included surface-mount hardware. This design is ideal for retrofitting existing sauna rooms or finishing new builds with minimal wall modifications.
V2 Digital WiFi Controller
The kit includes the V2 touchscreen WiFi controller , which supports session durations up to 60 minutes and maximum temperatures of 140°F. It can be controlled manually via the display or remotely through the SmartLife mobile app (iOS and Android).
