Custom Outdoor Sauna Options

When you choose the custom outdoor sauna route, you can design the sauna exactly how you’d like. 

How many people do you want to fit in your sauna?  Where is the sauna going to go?  What about windows?  

There are a lot of customizations you can put in your sauna, but we help you simplify things and will walk you through the process step-by-step.

All of our outdoor custom saunas are built right here in Minnesota.  Contact us to learn more about custom options in your outdoor sauna.

Customize Sauna Size & Layout

When it comes to dimensions, you can choose whatever you would like.  The most important factor to consider when it comes to the size of your sauna is how many people you are going to have in there at one time.  

Other factors to consider are : 

  • Do you want to lay down in the sauna?  
  • Where are the windows going to be (if you put windows in)?  Is there scenery that you want to look at?

Black Taika/ Hemlock Wood Interior

Interior Sauna Wood Type

All our wood is mill-direct, using only the highest quality, hand-selected wood. All from verified sustainable forests. All wood choices are chosen for their ability to hold up for years (typically decades) in the harsh sauna environment. 

All wood that touches skin (benches, backrests, duckboard flooring, heater guard, headrest) is chosen for staying cool to the touch of the skin (No knots – they get hot in the sauna heat!)

Four of the most common wood types we use on the interior of our saunas are clear western red cedar, clear canadian hemlock, black taika, and nordic spruce with abachi benching.  But, we do offer additional wood types such as heat-treated alder, aspen, knotty-cedar, and much more.  Don’t hesitate to ask us about additional wood types! 

Clear Western Red Cedar offers a luxury feel to the sauna with multiple different tones.  Cedar has a unique and desirable scent to it.

Unlike Cedar, Clear Canadian Hemlock offers a single wood tone.  It’s a brighter, reddish wood.  

Black Taika is certified birch plywood developed exclusively for high performance in the harsh sauna environment. 

European Grade A Nordic Spruce is commonly found in saunas in the Nordic Region, where saunas originated.
