How to Install Onyx Shower Walls

Onyx shower walls are a beautiful and luxurious addition to any bathroom. They add a touch of elegance and sophistication, and their natural beauty can create a truly stunning spa-like experience. Installing onyx shower walls can seem daunting, but with the right tools and techniques, it's a project that even DIYers can tackle. Here's a step-by-step guide to help you get started:

1. Preparation is Key

Before you begin, make sure you have all the necessary tools and materials, including:

  • Onyx shower wall panels: Choose the size, style, and finish that best suits your bathroom design.
  • Mastic adhesive: Use a high-quality mastic adhesive specifically designed for natural stone.
  • Backer board: This will provide a solid base for the onyx panels.
  • Grout: Choose a grout color that complements your onyx panels.
  • Silicone sealant: This will create a watertight seal around the edges of the panels.
  • Measuring tape: To accurately measure and cut the panels.
  • Level: To ensure the panels are installed straight.
  • Utility knife: For cutting the panels to size.
  • Grout float: To apply and smooth the grout.
  • Sponge: For cleaning up excess grout.
  • Safety glasses and gloves: For protection during installation.

Important: Carefully measure the shower area to determine the size and number of panels needed.

2. Preparing the Shower Wall

  • Remove Existing Tile: If you're replacing existing tile, carefully remove it using a hammer and chisel.
  • Clean the Wall: Thoroughly clean the shower wall to remove any dirt, debris, or old adhesive.
  • Install Backer Board: Install the backer board using construction adhesive and screws. Ensure it's securely attached and level.

3. Installing the Onyx Panels

  • Start at the Bottom: Begin installing panels from the bottom of the shower, working your way up.
  • Apply Mastic Adhesive: Spread a generous layer of mastic adhesive onto the backer board using a notched trowel.
  • Position the Panels: Carefully align and position the onyx panel on the adhesive, ensuring it's level and flush with the surrounding panels.
  • Secure the Panels: Once the panel is in place, gently press down to firmly adhere it to the adhesive.
  • Cut Panels as Needed: Use a utility knife to cut the panels to size where necessary, ensuring clean and precise cuts.

4. Grouting and Sealing

  • Apply Grout: Once the mastic adhesive has dried completely, apply grout to the joints between the panels using a grout float.
  • Clean Excess Grout: Immediately wipe away excess grout with a damp sponge, ensuring the grout lines are clean and consistent.
  • Seal the Edges: After the grout has cured, apply silicone sealant around the edges of the panels to create a waterproof seal.

5. Final Touches

  • Clean and Polish: Thoroughly clean the onyx panels to remove any remaining grout residue and polish them to a high shine.

Important: Be sure to follow the manufacturer's instructions for the specific onyx panels and materials you've chosen. This will ensure proper installation and longevity.

Tips for Success:

  • Work in small sections: Don't try to install all the panels at once. Work in manageable sections to ensure proper alignment and adhesion.
  • Use a Level: Constantly check the level of the panels to ensure a smooth and professional finish.
  • Clean up as you go: Wipe away excess mastic adhesive and grout immediately to prevent staining and ensure a clean installation.

With careful planning, preparation, and attention to detail, you can successfully install onyx shower walls and create a truly luxurious and breathtaking bathroom oasis.
