Dimensions & Layout

The size and layout of your indoor sauna is 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?  
  • Is there scenery you want to look at?
  • 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.

Interior 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!)

Any wood type available for the interior of the sauna is available for the outside of your sauna.  There are additional exterior options available – a common choice is LP Smart Paneling because its reasonable price and clean look.

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.  

Delivery & Installation

We’ll build the sauna on site, or, if we are able to get our shed hauler to the location of where the sauna is going – we’ll build the custom outdoor sauna in our shop and deliver the sauna to you.  

Otherwise, if you’d like to install the sauna DIY, that is an option too.  We can do as much or as little work as you want us to do.  We can supply all of the materials for your sauna uncut, or cut to spec.    

No matter which route you choose, our team will ensure that from the second we start talking about your sauna project to long after we leave that you are taken care of every step of the way.

A flat surface is required to install a sauna.  A concrete pad, deck (or platform of sorts), and pavers are ideal, but a class 5 base will work too.

Do I need a base for my outdoor sauna?

To build a custom sauna on your property, you’ll need a flat, level base.  Best case-scenario is a concrete pad, but pavers or a Grade 5 base will work.  A deck or other raised platform will work, too.  If we use a shed hauler to bring a custom outdoor sauna to your property we don’t necessarily need a platform to put the sauna on (because the sauna will be built on level ground in our shop), but it does help to have a base.  

Being from Minnesota and knowing the cold temperatures we will see through January and February, yes, all of our outdoor saunas are built and insulated to perform in and withstand Minnesota winters.  

Yes!  Not only do we have outdoor saunas on display in our sauna showroom, we also have the wood types that we build our custom outdoor saunas with on display. 

If you’ve never tried a sauna before and would like to try before you buy, give us a call @612.505.9700 to schedule an appointment! We have multiple display saunas that can be turned on and used (as well as a shower to clean up when you’re done).  We’re located in Cokato, Minnesota.  

We offer standard panel built outdoor saunas as well as customized outdoor saunas in a variety of sizes. Our Euro saunas come standard with a Clear Western Red Cedar exterior and Nordic White Spruce interior, but are completely customizable. 

Our NorthStar outdoor saunas utilize Nordic White Spruce on both the interior and exterior. 

 

Yes. In some cases, it’s actually possible to have both a wood fired heater and an electric sauna heater in the same sauna. 

It depends.  Can you run electric to your sauna?  If no, then wood-fired is your best choice (obviously).  

Wood-fired stoves generally get hotter than an electric stove and have a nice ambience to them.   

Electric stoves still get very hot (up to 194°) can be turned on from your phone, set to run certain automations (such as always turn on at 9AM), and integrate with the lighting system much easier.

Yes.  Whether you get an electric or wood-fired sauna stove you can pour water on the stove.  Every electric stove we sell is UL listed and designed to put water on.  

We highly recommend putting water on the stove.  It produces steam, which creates a great sauna experience.  

No.  While some companies will sell you an outdoor infrared sauna, we will not.  

Infrared saunas are designed to operate at lower temperatures (typically around 120°-130°) – this is not hot enough to work outdoors, especially in the wintertime.  

Absolutely.  A changing room is a great addition to the sauna.  

At a minimum you’ll need to run 240 volt power (assuming you choose the electric stove).  The amperage will depend on the stove you choose. 

Some sauna heaters integrate with the lights and don’t need additional 120 volt power to be run for lights to work, others do.  It depends on the stove and the lights. 

There are different code requirements for each area.  We recommend talking to a licensed electrician about any electrical questions you have.  

It depends on how warm you plan to get the sauna up to, but as a general rule it takes about 45 minutes to an hour to get up to temperature.
