Crafted with antimicrobial Western Canadian cedar that protects against mold, bacteria and fungus

Finnmark Design’s Western Canadian Cedar is 100% FSC™ certified that’s kiln dried for 3 days and air dried for 10 days. This process ensures you are receiving the perfect amount of moisture content in each T&G panel. In 2022, Finnmark Designs invested heavily into a process that is well know in Finnland, thermal modification. Using just heat and steam, our advanced technology transforms carefully selected, certified timber from sustainably managed forests into a range of inspiring and naturally chemical-free products. While many competitors are cutting costs, Finnmark Designs is investing into the future of providing sustainable and chemical-free saunas.

Innovative heating technology that produces 25x deeper sweat than Carbon heaters

Finnmark Designs utilizes advanced incoloy heater technology, engineered from traditional sauna methodologies, to provide a clean, natural infrared heat. These heaters, certified by the prestigious UL for safety, offer high output therapy for efficient sauna sessions. Additionally, they are designed to emit low EMF, incorporating research from leading experts in radiation exposure, ensuring a safer sauna experience.

Frequently Asked Questions

Are there any plastics or glues in the sauna?

Finnmark Designs constructs its infrared saunas with minimal use of glue, primarily behind the cedar tongue-and-groove slats to secure them, using a non-toxic glue that remains safe up to 250 degrees. Plastic components in the sauna, such as the accessory outlet, screw covers, and controller, do not off-gas until temperatures exceed 212 degrees, well above the sauna's maximum temperature. Additionally, Finnmark consulted with an environmental biologist who, after an initial review of the sauna's mostly cedar and metal interior, did not recommend further VOC or off-gassing testing.

Does the sauna bench have a weight limit?

The benches were built with extra support brackets and have a weight limit of 380 pounds.

What is the sauna height clearance?

Finnmark Design's saunas are engineered with the power supply in the ceiling to minimize EMF exposure. A minimum clearance of 6 inches is recommended for connecting wires, although some customers have managed with less.

What are the dimensions of the sauna bench?

The sauna benches come in three sizes: the Hybrid Bench measures 43 inches long by 21 inches deep, suitable for 2-3 people it is 49 inches long by 21 inches deep, and for 3-4 people it is 67 inches long by 21 inches deep.

Does the sauna have removable feet?

All Finnmark Designs saunas feature screw-in removable feet, designed to stabilize the unit on uneven floors. The feet measure 3 inches in height and 2 inches in width for all models.

Is the sauna easy to install?

Assembling a Finnmark Sauna is straightforward and typically requires about an hour with two people. No special tools are needed aside from a screwdriver for the door handle and panel assembly, as the sauna comes pre-wired for easy connection.

Can I use an extension cord to plug in my sauna?

Extending the power cord of your sauna will result in a loss of amperage for each foot extended, potentially affecting the sauna's peak performance. This loss depends on the type of wire used. Calculate Your Voltage Drop.

Can I use a Surge Protector or Power Strip?

Using an ordinary power strip or surge protector for a sauna is not recommended due to high amperage/wattage requirements. Finnmark Designs offers a 2,000-watt UPS surge conditioner for $799.00, though replacing a damaged sauna power supply costs only $450.00. Whole home surge protectors range from $300 to over $1,000, but their effectiveness can vary, as evidenced by a customer in Florida who lost several appliances despite having one. The advised solution is to plug the sauna directly into a newly installed wall outlet, considering the lower cost of replacing the sauna’s power supply compared to the expense of high-wattage surge protection options.

Should I replace my outlet for the sauna?

It is recommended to install a commercial-grade (preferably grey) outlet for your Finnmark Designs sauna to ensure reliability and reduce the risk of amperage loss, which can occur up to 10% per year with standard outlets due to loose wires and degrading connections. This approach helps safeguard your investment in the sauna, both financially and health-wise, by minimizing potential downtime.

How do I clean the sauna?

Maintaining your Finnmark Designs infrared sauna involves simple, non-toxic methods to preserve its Western Canadian cedar, which is air-dried to enhance its antimicrobial properties. For exterior cleaning, use a microfiber towel with water and apply a non-toxic beeswax wood conditioner; avoid chemicals on the glass, cleaning instead with just a microfiber towel and water. Interior cleaning should occur every 20-25 uses, depending on sweat volume. Use a microfiber towel with organic orange oil, let it sit for 10-15 minutes, then lightly sand with 320+ grit sandpaper. This gentle approach will not compromise the sauna's thick wood louvers in strength or durability.
