Dimensions & Layout

The size and layout of your sauna are important to consider before building the sauna.  

Factors to consider are : 

  • Where is the sauna going to go?
  • How many people do you want to fit in the sauna?
  • Do you want to lay down in the sauna?  
  • Electrical requirements.
  • Space requirements. 

We can help walk you through the process to ensure that the sauna is the right size and layout for you.   Call 612.505.9700 or reach us through our contact form for any questions you have!

Heater & Control

The sauna heater is the heartbeat of the sauna.  Each sauna heater has something to offer.  Warranty, steam quality, durability, Wifi (or not) to name a few. 

We will help you properly size your sauna heater and walk you through the different heater options available (and why you might choose one heater over another).  We offer both Wifi and knob-controlled electric sauna heaters.

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 (knots get hot in the sauna!)

Wood Types Available :

Duckboard Walkway

A duckboard walkway comes standard with each sauna kit.  Duckboards sit on the floor of the sauna and are walked on. 

Duckboards are nice to have, but they’re not a requirement.  Particularly if you put tile down in your sauna.  If your sauna floor is concrete, we recommend a duckboard.

Duckboards usually are built in the primary wood species of the sauna.

An additional duckboard can be purchased for outside of the sauna (entryway, etc).

Upper Bench Skirts

Upper bench skirts are an upgrade in the sauna.  They sit in between the lower and upper bench (lower bench skirts are available, just far less popular for convenience reasons). 

Bench skirts are popular in saunas for aesthetics purposes.  They help tie the look of the sauna together.

Our DIY Sauna Kit Process

We keep our custom DIY sauna kit process as simple as possible – without leaving out any critical details of your sauna build.  It starts with submitting a form or giving us a call at 612.505.9700.  Don’t hesitate to ask us any questions throughout the building process.

Submit a Form

It starts when you submit a quote, or give us a call (612.505.9700).  

After you submit a form, we’ll reach out to you about your sauna project!  

Discuss Sauna Details

We’ll walk you through the different sauna options available, preparation needed before installing a sauna, and answer any questions you have during the process.

Get Measurements

At this phase we’ll need exact measurements of your sauna so we can go on to the next step… 

Get a CAD

After you’ve decided on the custom options, we’ll get a CAD drawing for it.  You’ll still have time to change the sauna if you want. 

Build The Sauna Kit

After you’ve approved the CAD, the building process will start.  

Typically custom saunas have a lead time (duration changes throughout the year). 

Pickup or Delivery

We’ll let you know when the sauna is ready to be picked up or delivered!  

Building your own sauna is not as daunting as it may seem. If you can frame a room, you can install one of our custom DIY sauna kits. Below are some examples of saunas that all started with one of these same kits. Kits can be ordered as custom infrared, custom indoor, or custom outdoor
