Materials and Tools Needed: Before you begin, gather the following materials and tools:


  • Cedar, spruce, thermowood, redwood staves (pre-cut or raw, depending on your preference)
  • Stainless steel hoops or bands
  • Sauna door
  • Sauna heater
  • Insulation (optional, but recommended)
  • Ventilation system (optional)
  • Nails or screws
  • Sauna stones
  • High-temperature stove paint (if necessary)


  • Tape measure
  • Saw (circular or miter saw)
  • Drill
  • Screwdriver
  • Clamps
  • Hammer
  • Chisel
  • Level
  • Paintbrush

Step 1: Design and Planning Start by determining the size and location of your barrel sauna. Consider factors such as available space, privacy, and proximity to a power source. Sketch out your design, taking into account the number of seats you'd like to have and any additional features such as windows or a changing room.

Step 2: Acquiring Materials Purchase the necessary materials from a reputable supplier. Opt for high-quality cedar or redwood staves, as these woods are durable, resistant to decay, and provide a pleasant aroma. If you prefer a more rustic look, you can choose raw staves and cut them yourself.

Step 3: Constructing the Barrel Sauna a) Lay out the staves: Begin by laying out the staves in the desired order, ensuring they fit together snugly. Make any necessary adjustments to ensure a proper fit.

b) Securing the staves: Use clamps to hold the staves in place and drill pilot holes through each stave. Insert screws or nails into the holes to secure the staves together.

c) Attaching the hoops or bands: Install stainless steel hoops or bands around the barrel to provide structural support. Place them equidistant from each other and secure them tightly using screws or bolts.

d) Installing the sauna door: Follow the manufacturer's instructions to install the sauna door. Make sure it fits snugly and is properly sealed to prevent heat loss.

Step 4: Insulation and Ventilation (Optional) For enhanced energy efficiency and comfort, consider insulating your barrel sauna. Apply insulation material between the staves and cover it with a vapor barrier. Additionally, install a ventilation system to regulate airflow and prevent excessive humidity.

Step 5: Finishing Touches a) Applying heat-resistant paint: If desired, apply high-temperature stove paint to the exterior of the sauna. This not only enhances its appearance but also protects the wood from the elements.

b) Interior features: Install the sauna heater according to the manufacturer's instructions. Place sauna stones on top of the heater to generate heat and steam. You may also include benches, backrests, and lighting to create a cozy and inviting atmosphere.

Step 6: Safety Considerations. Ensure your barrel sauna is safe to use by following these precautions:

  • Install a carbon monoxide detector.
  • Use heat-resistant materials for the interior and exterior.
  • Ventilate the sauna properly.
  • Follow the manufacturer's guidelines for sauna heater installation and usage.
