FAQ

Finnmark offers infrared saunas as well as selected hybrid sauna models that combine infrared heating with a traditional sauna heater. Available sizes, heating systems, and features vary by model.

Finnmark hybrid models combine infrared heating with a traditional sauna heater, allowing users to enjoy different sauna experiences in one cabin. The exact heating configuration and features depend on the specific model.

Finnmark saunas commonly use Western Red Cedar in their construction. Always check the specifications for the exact model to confirm the materials used.

Depending on the model, Finnmark saunas may use Full Spectrum infrared heaters and carbon infrared heating technology. The exact heater configuration varies by model.

Full Spectrum infrared generally refers to heating technology designed to provide multiple infrared wavelength ranges, including near, mid, and far infrared.

Full Spectrum and carbon heating technologies can serve different purposes within an infrared sauna. Some Finnmark models use a combination of heater technologies to provide broad radiant heat coverage. Always review the specifications for the exact model.

Maximum operating temperature varies by model and installation conditions. Infrared saunas generally operate at lower air temperatures than traditional saunas while providing radiant heat directly to the body. Always refer to the specifications and owner's manual for your specific model.

Heat-up time depends on the model, room temperature, electrical supply, and selected temperature. Infrared heaters begin producing radiant heat quickly, although the cabin may require additional time to reach the desired temperature.

Finnmark provides EMF-related information and testing documentation for its sauna products. EMF measurements can vary depending on the specific model, testing method, and measurement location. Always review documentation for the exact model you are considering.

Many Finnmark sauna models are designed for home assembly using pre-manufactured components. Always follow the installation instructions for your specific model and ensure you have adequate assistance for moving and assembling heavy panels.

Tool requirements vary by model. Review the installation manual before beginning assembly to ensure you have the necessary tools and assistance.

Many Finnmark sauna models are designed for indoor installation. Choose a stable, level location with adequate space and access to the required electrical connection.

Only install a Finnmark sauna outdoors if the specific model is explicitly designed and rated for outdoor installation. Always follow the manufacturer's installation requirements.

Electrical requirements vary by model. Some models may use a standard household connection, while larger or hybrid models may require dedicated circuits or higher-voltage electrical service. Always check the specifications for your exact model before installation.

If your sauna requires a dedicated circuit, new outlet, higher-voltage connection, or other electrical modifications, a qualified electrician should complete the work according to applicable electrical codes and manufacturer requirements.

Electrical requirements depend on the specific model and power consumption. Always follow the manufacturer's electrical requirements and ensure the sauna is connected according to applicable electrical codes.

No. Water should not be poured on infrared heating elements. Infrared saunas are not designed to create steam by pouring water onto the heaters. For hybrid models with a compatible traditional sauna heater and sauna stones, water may be used according to the heater manufacturer's instructions.

Features vary by model but may include digital controls, Full Spectrum infrared heaters, carbon heating panels, tempered glass, Bluetooth or audio systems, interior lighting, and other comfort features.

Capacity varies by model. Finnmark offers different sizes, from compact personal saunas to larger multi-person models. Always review the individual product specifications for recommended capacity and dimensions.

Keep the sauna interior clean and dry, wipe surfaces with a soft cloth, and avoid harsh chemicals that could damage the wood or electrical components. Allow the sauna to cool and air out after use and follow the manufacturer's maintenance instructions.

Allowing the sauna to cool and air out after use can help keep the interior dry and fresh. Follow the manufacturer's maintenance recommendations for your specific model.

Finnmark saunas include a manufacturer's limited warranty covering defects in materials and workmanship. According to Finnmark's owner documentation, Spectrum+ heaters have lifetime coverage, while carbon heaters, craftsmanship, electrical components, and audio components are covered for 10 years. The lighting remote accessory is covered for 1 year.

Consider the sauna size, number of users, available installation space, heating technology, infrared versus hybrid heating, electrical requirements, assembly requirements, desired temperature, features, and warranty coverage before choosing a model.
