Are you tired of your old shower curtain and looking for a more permanent solution? Building a shower wall is more complicated than it may seem.

How to build a shower wall is a rewarding home improvement project that enhances both the functionality and aesthetic of a bathroom. Whether you’re remodeling or constructing a new space, creating a sturdy and water-resistant shower wall is essential. This process involves selecting suitable materials, such as waterproof backer boards and tiles, and understanding the necessary steps to ensure a long-lasting installation. By carefully planning and following a systematic approach, you can transform your shower area into a beautiful, durable home feature.

How to Build a Shower Wall

This guide will explain the basic steps and considerations for constructing a shower wall that combines utility with style.

What Will You Need?

Before starting any construction project, gathering all the necessary materials and tools is crucial. Here are some items you will need to build a shower wall:

  • Backer Board: This is a type of cement or fiberboard that creates a sturdy base for tiles by providing a water-resistant barrier.
  • Tiles: Depending on your budget and preference, you can choose from various tile options, such as ceramic, porcelain, and natural stone.
  • Tile Adhesive: This is used to adhere the tiles to the backer board.
  • Tile Spacers: These tiny plastic pieces help maintain even spacing between tiles during installation.
  • Grout: This mixture seals the gaps between tiles and stabilizes the overall structure.
  • Trowel: A notched trowel is used to apply the tile adhesive and grout.
  • Level: This tool ensures that your shower wall is installed straight.
  • Saw: Depending on the type of tiles you choose, you may need a manual or electric saw to cut them to size.

Once you have all the necessary materials and tools, it’s time to start building your shower wall.

9 Easy Steps on How to Build a Shower Wall

Step 1: Measure and Plan

The first and most crucial step in building a shower wall is meticulous planning and accurate measuring. Begin by assessing the space where the shower will be installed. Use a tape measure to determine the area’s dimensions, ensuring you have precise measurements of the width, height, and depth. This will help you calculate the backer board and tiles needed, minimizing waste and ensuring you have sufficient materials for the project.

Next, sketch a plan of your shower area, noting the position of plumbing fixtures such as faucets and showerheads and any niches or storage areas you wish to include. This blueprint will serve as a guide throughout the installation process, helping you visualize the final layout and make any necessary adjustments before construction begins.

Consider the pattern and orientation of the tiles as you plan. This might involve deciding whether you want a simple grid pattern or something more intricate like a herringbone or subway tile layout. Planning the tile layout helps avoid awkward cuts or misalignments once you start laying the tiles.

Step 2: Prepare the Surface

Before installing the backer board, ensure that the surface is clean, dry, and debris-free. Remove any existing wall coverings and repair any uneven areas on the wall. If the wall studs are exposed, inspect them for stability and replace any damaged or loose studs as needed. This preparation ensures a strong, even, and clean surface for attaching the backer board, which is crucial for the long-term durability of your shower wall.

Step 3: Install the Backer Board 

With the surface prepared, it’s time to install the backer board. Begin by measuring and cutting the backer board panels to fit the dimensions of your shower space, using a saw for accuracy. Once cut, position the backer boards against the wall studs, ensuring that their edges align with the center of the studs for stability. Secure the panels in place using corrosion-resistant screws spaced approximately 6 to 8 inches apart to prevent moisture penetration.

Make sure to leave a small gap between each panel, usually about 1/8 inch, to allow for slight expansion. After all panels are mounted, use fiberglass tape and thin-set mortar to seal the seams and any screw holes, reinforcing the water-resistant barrier and preparing the surface for tile application.

Step 4: Plan the Tile Layout 

Before applying tile adhesive, take the time to plan the tile layout on the backer board. Use a pencil and level to draw light guidelines directly on the surface. This will help ensure straight and even rows. Dry-lay a row of tiles on the floor to experiment with the desired layout, considering any tile cuts that will be necessary. Align the starting point based on your preference, whether at the ceiling or base and work towards the opposite edge, ensuring a symmetrical and pleasing design. Taking this time upfront to plan and visualize the tile pattern accurately will greatly simplify the installation process and contribute to a professional finish.

Step 5: Apply Tile Adhesive

Once the tile layout is planned and marked, it is time to apply the tile adhesive. Begin by mixing the adhesive according to the manufacturer’s instructions. Using a notched trowel, spread the adhesive onto a small section of the backer board, starting from the bottom and working your way up. The notched edges of the trowel help create even ridges in the adhesive, ensuring a consistent base for the tiles to adhere to. Work in sections that allow you to install tiles before the adhesive begins to set.

Carefully press each tile onto the adhesive, using tile spacers to maintain consistent gaps between them. Check that the tiles remain level and aligned with your guidelines as you work. Adjust any tiles as necessary before the adhesive sets, ensuring a professional and aesthetically pleasing result.

Step 6: Cut and Fit Tiles 

As you progress with tiling, you may encounter areas where whole tiles don’t fit, such as around fixtures or edges. To address this, you must cut the tiles to the appropriate size. Start by measuring the area where the tile will fit, taking precise measurements to ensure a snug fit. Transfer these measurements onto the tile, marking clearly with a pencil. Depending on the material, use a tile cutter or wet saw to make clean, accurate cuts. Always wear appropriate safety gear, like goggles and gloves, when cutting tiles. Once cut, position the tiles into the remaining spaces, ensuring they align with your layout and adhere well to the adhesive.

Step 7: Grout the Tiles 

After installing all the tiles and allowing the adhesive to cure fully, the next step is grouting. Mix the grout according to the manufacturer’s instructions until you achieve a smooth, consistent texture. Using a rubber float, apply the grout diagonally across the tiles to ensure it fills all gaps and joints thoroughly. Work in small sections, and press the grout firmly into the spaces to prevent any voids. After applying the grout, clean the excess from the tile surfaces with a damp sponge, rinsing frequently to avoid leaving any residue. Allow the grout to set slightly before polishing the tiles with a dry cloth to remove haze.

Step 8: Seal the Grout

Once the grout has cured completely, sealing the grout lines is critical to ensure long-term protection against moisture and stains. Choose a high-quality grout sealer and follow the manufacturer’s instructions for application. Apply the sealer using a small brush or applicator tool, ensuring it thoroughly penetrates all the grout lines. Avoid getting the sealer on the tiles, as this can create a visible residue. Allow the sealer ample time to dry fully, as specified by the instructions, before using the shower. Regularly maintaining the grout by resealing it as needed will help preserve the integrity and appearance of your tiled shower wall, providing a finished look that stands the test of time.

Regularly Maintaining the Grout

Step 9: Install Shower Fixtures 

Install the shower fixtures once the tile and grout work is wholly sealed and dry. Begin by carefully aligning the fixtures’ mounting brackets with pre-existing plumbing and ensuring they are securely fastened. Follow the manufacturer’s instructions for attaching fixtures such as the showerhead, faucet, and other accessories like soap dishes or grab bars. Use a level to ensure everything is aligned correctly and adjust as necessary for an even appearance. Apply a bead of silicone sealant around the edges of installed fixtures to prevent water intrusion and enhance durability.
