Custom Outdoor Saunas

Your dream sauna.

The traditional Finnish sauna is based on the outdoors. Our outdoor saunas can be both electric, or wood fired (or both).  

Adding a sauna to your backyard or outdoor space is a welcome escape from the hustle and bustle of every day life. Saunas are a place to relax and unwind and many of our customers (ourselves included) find themselves in the sauna both morning and night.

The options for a custom sauna are endless.  Choose the sauna layout & design, wood type, windows, benching a whole lot more.  Our design team works with existing structures or from the ground up, delivering you a dream outdoor sauna space unlike any other.  Contact us to get started on your dream custom outdoor sauna. 

Custom Sauna Options.

Going the custom outdoor sauna route allows you to design your sauna to truly fit your vision.  

All of our custom saunas are Minnesota built.

Step 1:

Size & Layout

There is a wide range of dimensions that you can pick for your outdoor sauna.

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 space to layout?  How much space in your yard?

Step 2:

Heater & Control

The sauna heater is the heartbeat of the sauna, the most critical factor for the best sauna experience.

After you have decided on the size and layout of the sauna, we find the appropriately sized heater for it.  Each heater will offer a different experience.  Our residential Finnleo heaters comes with a five-year warranty and we stock all of the most common heater parts you could need. Our American tech support team supports customers across North America every week of the year Monday through Friday. 

The Himalaya Rock Tower is a premium heater.  Because of its rock mass and Biowater Technique Tank, it creates a soft heat for the best sauna experience.  

The Designer Series is a reliable, sturdy sauna heater.  It is built to withstand heavy use and heats up quickly because of its smaller rock mass.

The standard control is the SaunaLogic 2.0 Control w/ Wifi.  Control your sauna from your phone.  

The Custom Sauna can come with a wood-fired heaterLet us know if that is the route you want to take.  

Step 3:

Wood type

Each wood type offers a different feel.

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!)

Step 4:

Interior Design

Customizing the interior design allows you to change up (or not) the wood type and look of the benching and backrests from the walls.

There are four different styles of benching & backrest interior design.  Each look is available for your sauna.  

Standard

Standard interior can be done in all wood types. 

Deco

Deco interior is built with Hemlock and Heat-Treated Alder wood benching. Best paired with Cedar or Hemlock T&G.

Centurion

Centurion interior is built in wide board Hemlock wood. Best paired with Taika T&G.

Twilight

Twilight interior is built with a Abachi & Heat-Treated Alder.  Best paired with Hemlock or Cedar T&G.

Step 5:

Backrest

All Custom Saunas come with a standard 2-Bar backrest.

A backrest in the sauna is comfortable, looks nice, and keeps your skin off the T&G walls.  There are several upgraded backrest options to put in your sauna.

Step 8:

Lighting

Sauna lighting is critical for the ambiance of the sauna. 

There are multiple different options for sauna lighting.  The most common is the RGBW Strip Lighting, but it’s not the only option.  

The RGBW LED strip lighting and the RGBW LED puck lights are compatible with the SaunaLogic 2.0 Control.  Change the light color and brightness to suit your liking.  The lights can be purchased and set up a la carte too.  

RGBW LED Strip Lighting

LED strip lighting comes pre-installed behind your backrest. Can also be placed under bench. 

  • Pairs with the SL2 control and app
  • Cycle through multiple colors, or white
  • Dimmable

RGBW Puck Lighting

Step 9:

Duckboard Walkway

A duckboard is visually appealing and gets your feet off the floor.

A duckboard walkway comes standard with the sauna.  A duckboard is nice to walk on and looks good in the sauna, but it’s not a requirement to have one.  

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