DIY - Installing a Barrel Sauna in Your Backyard

If you're looking for a unique way to relax and unwind in your own backyard, installing a barrel sauna might be just the thing for you. A barrel sauna is a small, cylindrical sauna that is made from wood and is a perfect addition to any backyard. In this DIY guide, we'll walk you through the steps to install a barrel sauna in your own backyard.

Materials Needed

Before you get started, you'll need to gather the following materials:

  • Barrel sauna kit
  • Foundation material (such as gravel or concrete pavers)
  • Level
  • Hammer
  • Drill
  • Screws
  • Screwdriver
  • Saw
  • Tape measure
  • Insulation material
  • Sauna heater
  • Copper wire
  • Wood stain or sealer

Step 1: Choose a Location

The first step in installing a barrel sauna is to choose a location. You'll want to find a flat, level area in your backyard that is easily accessible. Keep in mind that the sauna should be placed at least 3 feet away from any combustible materials, such as a fence or shed.

Step 2: Prepare the Foundation

Once you've chosen a location, you'll need to prepare the foundation. Lay down a layer of foundation material, such as gravel or concrete pavers, to create a level surface for the sauna. Use a level to ensure that the foundation is even and stable.

Step 3: Assemble the Sauna

Next, it's time to assemble the sauna. Follow the instructions provided with your barrel sauna kit to assemble the walls, floor, and roof of the sauna. Use a saw to cut any necessary openings for windows or doors.

Step 4: Insulate the Sauna

After assembling the sauna, you'll need to insulate it to ensure that it retains heat efficiently. Use insulation material, such as fiberglass or foam board, to insulate the walls, floor, and ceiling of the sauna. Be sure to seal any gaps or seams with tape to prevent heat loss.

Step 5: Install the Sauna Heater

Once the sauna is insulated, you can install the sauna heater. Follow the manufacturer's instructions to install the heater, which will typically involve connecting it to a power source using copper wire. Be sure to choose a heater that is appropriately sized for the size of your sauna.

Step 6: Seal the Sauna

To protect the sauna from the elements, you'll need to seal it with a wood stain or sealer. Apply the stain or sealer to the exterior of the sauna, following the manufacturer's instructions. This will help to protect the wood from moisture and prevent it from warping or rotting.

Step 7: Enjoy Your Sauna!

Once the sauna is fully assembled and sealed, you're ready to start enjoying it! Be sure to follow the manufacturer's instructions for operating the sauna safely and effectively. With proper use and maintenance, your barrel sauna will provide years of relaxation and enjoyment.


Installing a barrel sauna in your backyard can be a fun and rewarding DIY project. With the right materials and tools, you can create a relaxing oasis in your own backyard that you can enjoy for years to come. Remember to take your time, follow the instructions carefully, and prioritize safety to ensure that your barrel sauna is installed correctly and operates effectively.
