  • Measuring tape
  • Level
  • Saw (such as a circular saw or jigsaw)

2. Prepare the Shower Area

Before installing the cultured marble panels, you’ll need to prepare the shower area. This includes:

  1. Clean the walls thoroughly. Ensure there is no dirt or debris on the walls that could interfere with the adhesive.
  2. Check that the walls are level. If they are not, use a leveling compound to even out any uneven spots.
  3. Apply a moisture barrier to the walls. This will help prevent moisture from seeping through the walls and causing damage.

3. Measure the Walls

Before ordering your cultured stone marble panels, measure the walls to ensure you order the correct amount. Here’s how to do it:

  1. Measure the height of the shower wall from the base to the ceiling.
  2. Measure the width of each wall from side to side.
  3. Multiply the height by the width to get the square footage of each wall.
  4. Add up all the walls’ square footage to get the total square footage needed for the cultured natural marble panels.

4. Cut and Install the Panels

Now that you have your cultured marble panels and measured the walls, it’s time to cut and install them.

  1. Cut the panels to size using a saw. Make sure to wear safety glasses and gloves when cutting the panels.
  2. Cut holes in the panels for any plumbing fixtures using a drill and hole saw.
  3. Dry-fit the panels to ensure they fit properly.
  4. Apply adhesive to the back of every panel, covering the entire surface.
  5. Press the panels onto the walls, starting at the bottom and working up. Make sure to use a level to ensure the panels are straight.
  6. Use clamps to hold the panels in place until the adhesive dries.

5. Apply Adhesive

The adhesive used to secure the cultured marble panels to the walls is an important component of the installation process. Here’s how to apply it:

  1. Apply the adhesive to the back of each panel using a caulk gun or trowel.
  2. Make sure to cover the entire surface of the panel with adhesive.
  3. Press the panel onto the wall, ensuring it is straight and level.
  4. Use clamps to hold the panel until it dries.

6. Finishing Touches

Once the cultured marble wall panels like marble countertops are installed, it’s time to add the finishing touches. This includes:

  1. Caulking around the edges of the panels to ensure a watertight seal.
  2. Sealing any gaps between the panels and plumbing fixtures.
  3. Cleaning the panels thoroughly to remove any adhesive or caulk residue from shower wall.
  4. Applying a sealer to the panels to protect them from moisture and stains.

7. Clean-Up and Maintenance

After the installation, cleaning up the work area and maintaining the cultured marble products is essential to ensure they last for years to come.

  1. Clean up any adhesive or caulk residue with a scraper and cleaning solution.
  2. Dispose of any waste materials properly.
  3. Regularly clean the shower walls by using a soft cloth or sponge.
