Description
The Finnmark Spectrum Plus Infrared Heater Panel Kit gives you everything you need to heat a custom infrared sauna or upgrade an existing one. These are the same high-output Spectrum Plus heaters that heat Finnmark's own saunas. Each kit is matched to a specific room size, from a 4' x 4' single-person build up to a large 6' x 10' room, and comes with every heater, power cable and sensor you need to.
Spectrum Plus heaters put out up to 55% more infrared heat than standard carbon panels and bring your custom sauna up to 170°F with very low EMF.
Finnmark's V2 Wi-Fi touchscreen control is required to operate the infrared heating panels.

How Delivery Works
How Delivery Works
Your heater kit ships on a pallet via freight carrier, with a scheduled delivery appointment. Here's what to expect:
1. Pick Up From Warehouse
Once your order is placed we request a freight carrier to pick up your kit. Pick up usually happens within 1-3 business days.
2. Transit to Your Local Terminal
Your kit travels to the freight terminal closest to you. The carrier will call you directly to schedule a delivery appointment — it won't be delivered without one.
3. Delivery Day
On your scheduled date, the carrier will lower the pallet to the ground at your curb. Free shipping includes curbside delivery.
When your kit arrives, inspect the packaging before signing. If you notice any damage, note it on the delivery receipt and email us photos at info@sunvalleysaunas.com — we'll handle it from there.
Total estimated delivery time: 5–10 business days from order placement, depending on your location. Some deliveries take a little longer.

Frequently Asked Questions
Frequently Asked Questions
How do I choose the right kit size?
Pick the kit that matches your sauna room's interior floor size. Each kit is built with the right number of heaters for that room. If your room falls between sizes, call or text us and we'll help you match it.
Do I need the control?
Yes. The kit doesn't include a control, and it requires the Finnmark V2 Wi-Fi control to run. Choose the control bundle above to get both in one order.
What electrical service do I need?
The 4' x 4' kit runs on 120V at 17.5 amps and comes with a 120V 20A power cable. Every other size runs on 240V single phase, between 14.59 and 24.8 amps depending on the kit. Have a licensed electrician confirm the circuit before installation.
How hot will my sauna get?
Spectrum Plus heaters can bring a room up to 170°F. How quickly a room heats and how hot it gets depend on how well it's built and insulated.
Can I use this kit to upgrade an existing sauna?
Yes. The kits are designed for both new custom builds and retrofits of existing saunas, using pocket installation.
