DIY Home Improvement: Build Your Own Sauna


When it comes to comfort, some desire just a little bit more out of their home. Installing a personal sauna can be the ultimate luxury item and, believe it or not, can be installed on a limited budget as a do-it-yourself project. The total cost of materials and supplies will come out to around $1,000-$2,500, but could be even less if you go with equipment rental for all your tool requirements.


1. Remove the Drywall

First, remove all the drywall off the walls in the location where you plan to install the sauna. The only thing that should be left are the studs of the wall frame and ceiling.

2. Provide Electrical Wiring and Insulation

Create an electrical wire that runs into the future sauna that can provide light and electricity for the vent, and heater. To some this may seem easier said than done, so if in doubt hire a professional to deal with the electrical, get estimates and plan the budget accordingly. Then cover up the electrical wiring with some heavy duty insulation rolls that will help retain heat within the room and alleviate the strain placed on the heater.

On top of the insulation, add a layer of foil and staple the foil onto the walls and ceilings. Then use foil tape between the layers to keep everything closed off and prevent heat and/or vapor from escaping. If too much vapor is allowed to escape, it can damage the foundations of your home and travel to other rooms in the house.


3. Framing the Walls

Take cedar boards and measure out the width of the room. Cut the boards with a power saw to create a groove at the end of the board so that they fit tightly against each other. Drill the boards horizontally into the wall and onto the studs and repeat this process until the entire wall is covered in cedar planks. Use a power saw to cut out a neat area for the light socket from the boards.

Then create a bench to sit on within the sauna. The bench should be mounted on the wall with supports and approximately 18” deep.

4. Setting Up The Heater

Determine where you are going to mount the heater on the wall so that it is out of the way and nearby your vent to draw air. Nail the heater into the cedar planks and make sure that it isn’t touching the ground as this could impede airflow. The farther out of the way you can place the heater, the better as this will help to prevent any burns that could occur from accidentally bumping into it.

5. Adding a Door

Seal off the sauna with a door that fits the frame and that closes tightly to keep the heat from escaping. The door should be made out of the same cedar materials that are used in the interior of the sauna. Some companies make pre-constructed doors designed for the use of residential saunas, so if you want to save yourself time and avoid building a door yourself after putting together an entire sauna, you might want to look into that option and find something that fits your specifications.
