FlexStone shower walls are a popular choice for bathroom renovations because they are durable, easy to clean, and visually appealing. Installing FlexStone shower walls involves several steps, and it’s important to follow the manufacturer’s instructions for your specific shower kit. Here’s a general guide on how to install FlexStone shower walls:

Materials You’ll Need:

  • FlexStone shower wall kit
  • Measuring tape
  • Level
  • Pencil
  • Construction adhesive (recommended by the manufacturer)
  • Caulk gun
  • Utility knife
  • Jigsaw or circular saw (if necessary)
  • Silicone caulk
  • Safety goggles and gloves
  • Support bars or brackets (if required)


  1. Safety Precautions:
    • Wear safety goggles and gloves to protect yourself during the installation process.
  2. Inspect the Kit:
    • Examine the FlexStone shower wall kit to ensure that all components are present and in good condition. Verify that you have the correct size and style for your shower.
  3. Prepare the Surface:
    • Ensure that the shower area is clean, dry, and free of any debris, old tiles, or adhesive. The wall surface should be smooth and even.
  4. Measure and Mark:
    • Measure the shower area carefully to determine the exact placement of the shower walls. Use a pencil to mark horizontal and vertical reference lines on the walls to guide the installation.
  5. Cut Panels (if necessary):
    • If your shower walls require cutting to fit, use a jigsaw or circular saw to trim the panels according to your measurements. Always follow the manufacturer’s guidelines for cutting FlexStone panels.
  6. Apply Adhesive:
    • Apply the recommended construction adhesive to the back of the FlexStone panels. Spread it evenly over the entire surface of the panels, paying attention to the edges and corners. Use enough adhesive to ensure a secure bond.
  7. Position the Panels:
    • Carefully place the FlexStone panels onto the prepared wall surface, aligning them with your reference lines. Press the panels firmly against the wall to ensure good adhesion.
  8. Check for Level and Plumb:
    • Use a level to check that the panels are both level horizontally and plumb vertically. Make any necessary adjustments to ensure a precise fit.
  9. Secure Panels (if required):
    • Depending on the specific FlexStone kit, you may need to secure the panels to the wall using support bars or brackets provided by the manufacturer. Follow the instructions for your kit to install these supports.
  10. Seal Joints and Edges:
    • Seal all joints, edges, and seams between the panels using silicone caulk. Ensure a watertight seal to prevent moisture from seeping behind the panels.
  11. Trim and Finish:
    • Use a utility knife to trim any excess caulk or adhesive. Allow the caulk to dry according to the manufacturer’s recommendations.
  12. Install Accessories (if desired):
    • Install any accessories such as soap dishes, corner shelves, or grab bars as needed.
  13. Final Inspection:
    • Inspect the installed FlexStone shower walls for any gaps, imperfections, or areas that may require additional sealing or finishing.

Properly installed FlexStone shower walls can enhance the appearance of your bathroom and provide a durable and low-maintenance shower enclosure. Always follow the manufacturer’s instructions and guidelines for your specific kit to ensure a successful installation.
