This guide will walk you through everything you need to know about installing a glass wall in your sauna.

Why Add a Glass Wall to Your Sauna?

Before we dive into the steps, let's explore the benefits of adding a glass wall to your sauna:

  • Aesthetic Appeal: Glass walls give your sauna a modern and luxurious look.
  • Natural Light: They allow natural light to enter, creating a brighter and more inviting space.
  • Illusion of Space: Glass walls make small saunas feel more spacious and open.
  • Enhanced Experience: Enjoy the view outside or watch the snowfall as you relax in your sauna.

Materials and Tools Needed

Here's a list of materials and tools you'll need for this project:

  • Tempered glass panel (specific to sauna use)
  • Glass door (optional)
  • High-quality silicone sealant
  • Sauna wood paneling
  • Wooden frame (to support the glass)
  • Screws and nails
  • Drill
  • Measuring tape

Step-by-Step Guide to Adding a Glass Wall to Your Sauna

1. Plan and Measure

Start by planning where you want to install the glass wall. Measure the dimensions of the space accurately. It's crucial to get precise measurements to ensure the glass fits perfectly.

  • Measure the height and width of the wall opening.
  • Determine if you'll need a full glass wall or a combination of glass and wood.

2. Select the Right Glass

Choose tempered glass specifically designed for sauna use. Tempered glass is heat-resistant and sturdy, making it ideal for the sauna environment. For sourcing of this glass feel free to give us a call at (360)-233-2867 or send us an email at

  • Consider the thickness of the glass; 8-10mm is generally recommended.
  • Decide on any additional features like frosted or tinted glass for added privacy.

3. Prepare the Frame

Construct a sturdy wooden frame to support the glass wall. The frame will anchor the glass securely and provide a base for installation.

  • Use sauna wood, which is resistant to heat and moisture.
  • Ensure the frame is level and square.

4. Install the Frame

Attach the wooden frame to the sauna wall. Use screws and a drill to secure it firmly.

  • Double-check that the frame is level.
  • Make sure the frame is securely attached to the structure of the sauna.

5. Position the Glass

Carefully place the glass panel into the frame. You might need an extra pair of hands for this step due to the weight and size of the glass.

  • Wear safety gloves and glasses to protect yourself.
  • Ensure the glass fits snugly into the frame without gaps.

6. Seal the Edges

Apply a high-quality silicone sealant along the edges of the glass to create a watertight seal.

  • Use a caulking gun to apply the sealant smoothly.
  • Let the sealant cure as per the manufacturer's instructions.

7. Install the Glass Door (Optional)

If you're adding a glass door, follow the manufacturer's instructions for installation. Ensure the door aligns perfectly with the glass wall and operates smoothly.

  • Install hinges and handle as needed.
  • Test the door to ensure it opens and closes properly.

Maintenance Tips

To keep your glass wall in top condition, follow these maintenance tips:

  • Regular Cleaning: Use a non-abrasive glass cleaner to keep the glass sparkling clean.
  • Check Sealants: Periodically check the silicone sealant for any signs of wear or gaps and reapply as necessary.
  • Inspect the Frame: Ensure the wooden frame remains in good condition and is free from moisture damage.
