DIY SAUNA KITS

Custom DIY Saunas.

Pre-built sauna kits for your space.

Our DIY custom cut sauna kits come fit to your space.  The only cuts you’ll be required to make is on the trim.  We do also offer custom modular (panel-built) saunas too.  

When you build a custom sauna, you can build to fit your style, look, and vision.  Our DIY sauna kit can help you do that.  With our sauna kit you can take a framed and insulated room and turn it into a sauna. 

The options for your sauna are nearly endless.  Whatever you dream up, we can get you a custom sauna kit for it.  

What's Included In The Sauna Kit?

everything you need for your sauna .

All custom DIY sauna kits include everything you need to complete the interior of your sauna space beyond framing and insulation. That includes foil vapor barrier, T&G, pre-built upper and lower benching, sauna heater & rocks, sauna door, backrest, heater guard, headrest(s), vent grills, sliding vent valve, duckboard flooring for walk area, bucket & ladle, corner & ceiling trim, interior door casing, and hardware package. 

Building a custom sauna with infrared panels is also an option. 

Our sauna kits include only the highest quality materials, for both form and function. From Clear Western Red Cedar, Finnleo Black Taika, Nordic Spruce, or Clear Canadian Hemlock, your sauna space will hold up to even the most hard-core of sauna use for decades to come. 

All wood in a custom cut kit is cut and pre-built to your exact dimensions. 

You do not need to take everything listed in the kit! Pick and choose the pieces you need. 

Step 1:

Wood Type

After your initial sauna measurements are provided, you’ll select a wood type for your pre-cut sauna kit. 

Sauna wood types to choose from:

Our sauna in a box kits contain the interior tongue and groove wood for all walls and the ceiling of your sauna. We’ll work with you to determine the exact exterior look of your sauna whether it be drywall or wood and can create this to your exact specs.

Step 2:

Heater & Control

The heater is the heart and soul of the sauna.  Each heater offers a different sauna experience.  

The electric Himalaya Rock Tower is arguably the most popular heater you can get.  The Designer Series offers reliability at a better price point.  Thinking of building a wood-fired sauna?  No problem, we have options for those too! 

The SaunaLogic 2.0 Control allows you to control your electric sauna heater from you phone.  It’s programmable, so you can set it to automatically warm up on a schedule.  

Step 3:

Light Therapy & Sound System

Our custom built pre-cut sauna kits are limitless in their customization options and a major component of the best sauna bathing experience is color light therapy. 

Our LED lighting system is customizable for your entire sauna room. Whether you’d like standard backrest lighting, puck lighting in the ceiling, or lights behind the backrest and under benches. 

A custom sauna should be built to your exact specifications and our entire process is exactly that. If you can dream it, there’s a good chance we can build it.

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