Pre-Cut Sauna Kits

Finnmark Designs takes building your own custom sauna to the next level.  Our expertise coupled with our strong attention to detail yields some of the best looking customs saunas in the US. 


Many online “sauna” companies will sell you a sauna kit.  What they don’t do is help you with choosing the right bench elevations, wood type, heater size, heater position and so many more variables that if done wrong can negatively affect your overall sauna experience.  Finnmark Designs guarantees you build the sauna of your dreams the right way the first time.

Our Heater Lineup is Impressive

Too many “sauna builders” carry one maybe two different brands of heaters.  This puts your sauna design and build at an immediate disadvantage.  We have yet to find a heater brand that has it all.  

Finnmark Designs has access to four different traditional heater brands as well as it’s own line of Spectrum Plus™ infrared heaters.  Our heater lineup gives you the options needed to build the sauna of your dreams.  

From Basic to Exotic Woods

Outfit your new sauna with everything from cedar to exotic brushed black alder.  Finnmark Designs stocks dozens of different types of lumber along with the design skills to ensure your sauna is one of a kind.  

FREE CAD drawing ($599 Value)

We don’t build the CAD cost into your sauna quote, we provide this at essential part of your build at no cost.  Unlike many competitors, we employ a full-time CAD engineer that can help you visualize the sauna of your dreams before construction even starts.  

To start your sauna design let’s book a time to review your vision.
