Prepare the shower wall surface: clean, dry, and ensure it's smooth, flat, and ready for tile installation
A pristine, smooth wall is the unsung hero of a flawless hexagon tile installation. Any imperfection—a speck of dust, a hairline crack, or a subtle bump—will telegraph through the tiles, marring your masterpiece. Think of it as the canvas for your mosaic: the cleaner and flatter the surface, the more stunning the final artwork.
Step 1: Clean ruthlessly. Shower walls are magnets for soap scum, mildew, and invisible oils. Use a degreasing cleaner (like TSP substitute) mixed at a ratio of ½ cup per gallon of warm water. Scrub vigorously with a non-abrasive pad, paying extra attention to corners and grout lines if you’re retiling. Rinse thoroughly—residual cleaner can weaken adhesion—and allow the wall to dry for 24 hours. Pro tip: Wear gloves and ensure ventilation; TSP is no joke.
Step 2: Assess and repair. Once clean, inspect the wall under bright light. Hairline cracks? Fill them with a waterproof patching compound, smoothing it flush with a putty knife. Uneven drywall seams? Sand them down with 120-grit sandpaper until level. For concrete walls, wire-brush any loose material and vacuum debris. The goal: a surface so flat that a straightedge reveals no gaps when placed against it.
Step 3: Prime for perfection. Even if your wall looks ready, don’t skip primer. A coat of alkali-resistant, tile-specific primer (like RedGard or Mapei’s Eco Prim Grip) seals porous surfaces and enhances mortar bond. Apply with a roller or brush, following the manufacturer’s drying time—typically 2–4 hours. This step is non-negotiable for longevity, especially in moisture-prone showers.
Cautionary tale: Skipping surface prep is the most common DIY pitfall. A client once installed hex tiles over a seemingly clean wall, only to have them pop off within months. Why? Hidden soap residue prevented mortar adhesion. Moral: Invest time upfront to avoid costly (and soggy) regrets.
Final takeaway: Preparing the wall is 80% of the battle. A clean, dry, and smooth surface ensures tiles adhere like a second skin, preventing cracks, gaps, and water intrusion. Treat this phase with the reverence of a surgeon—your hexagon masterpiece depends on it.

Plan tile layout: measure, mark, and create a grid pattern to guide hexagon tile placement
Accurate planning is the cornerstone of a successful hexagon tile installation on a shower wall. Before adhesive meets tile, you’ll need to measure, mark, and create a grid pattern to ensure a seamless and symmetrical layout. Start by measuring the height and width of your shower wall, noting any obstructions like fixtures or niches. Use a tape measure and record dimensions to the nearest 1/16 inch for precision. This initial step prevents wasted tiles and ensures a balanced design, especially when working with hexagon tiles, which require careful alignment to avoid a chaotic appearance.
Once measurements are in hand, mark the center point of each wall both horizontally and vertically. This creates a crosshair that serves as the starting point for your grid. Use a level and a pencil to draw vertical and horizontal lines extending from these center points to the edges of the wall. These lines will act as guides for placing your first row and column of tiles, ensuring symmetry. For larger walls, consider adding additional reference lines every 12 to 18 inches to maintain alignment across the entire surface.
Creating a grid pattern tailored to hexagon tiles requires understanding their unique geometry. Unlike square or rectangular tiles, hexagons interlock in a honeycomb pattern, which means each row is offset by half a tile. To visualize this, lay out a few rows of tiles on the floor or a large surface, starting from the center and working outward. This dry run helps you identify how the pattern will flow and where cuts might be necessary. Transfer this logic to your wall by marking the positions of the first few tiles along your guide lines, ensuring the pattern aligns with your center points.
Practical tips can streamline this process. Use chalk lines or a laser level for straight, consistent marking, especially on larger walls. If your shower has a niche or bench, plan the tile layout around these features first, as they often dictate the flow of the pattern. For walls with uneven dimensions, adjust the grid to center the pattern rather than forcing it to fit, which can lead to awkward cuts or misalignment. Finally, double-check all measurements and markings before committing to the layout, as corrections become costly and time-consuming once tiles are adhered.
The takeaway is clear: meticulous planning in the layout phase saves time, materials, and frustration during installation. By measuring accurately, marking strategically, and creating a grid that respects the hexagon’s geometry, you set the stage for a polished and professional finish. This step is not just about aesthetics—it’s about ensuring structural integrity and longevity in a high-moisture environment like a shower. Invest time here, and the rest of the installation will fall into place with far greater ease.

Apply thin-set mortar: use a notched trowel to spread mortar evenly on the wall
The notched trowel is your secret weapon for a flawless hexagon tile installation. Its serrated edge creates grooves in the thin-set mortar, ensuring optimal adhesion and preventing air pockets that can lead to tile failure. Think of it as creating a textured surface for the tile to grip onto, like Velcro for your shower walls.
Choosing the right notch size is crucial. For most hexagon tiles, a 1/4-inch V-notch trowel is ideal. This size allows enough mortar to adhere to the tile's unique shape without creating excess that squeezes out the sides.
Hold the trowel at a 45-degree angle and apply firm, even pressure as you spread the mortar in a thin, consistent layer. Aim for a coverage of approximately 80-90% of the wall surface. This might seem counterintuitive, but leaving some areas slightly exposed allows for better tile-to-mortar contact and prevents the tiles from shifting during installation.
Work in small sections, typically no larger than 2-3 square feet at a time. This prevents the mortar from drying before you can set the tiles, ensuring a strong bond. Remember, thin-set mortar has a limited working time, usually around 20-30 minutes, so plan your workflow accordingly.
Don't be afraid to get a little messy. Some mortar will inevitably squeeze out between the tiles as you press them into place. This is normal and can be easily wiped away with a damp sponge after the tiles are set. Just be sure to wait until the mortar has hardened slightly, usually after about 15-20 minutes, to avoid disturbing the tiles.

Set hexagon tiles: press tiles firmly into mortar, maintaining consistent spacing and alignment
Pressing hexagon tiles firmly into the mortar is a critical step that ensures both adhesion and aesthetic appeal. Unlike square or rectangular tiles, hexagons require precise placement due to their unique shape and the honeycomb pattern they create. Start by applying a generous, even layer of mortar to the wall using a notched trowel. The notch size should correspond to the tile size—typically a 1/4-inch notch for 2-inch hexagons. Press each tile firmly into the mortar, using slight twisting motions to ensure full contact. This action embeds the tile into the mortar bed, creating a strong bond that resists moisture and movement, essential for shower walls.
Maintaining consistent spacing and alignment is equally vital to achieving a professional finish. Hexagon tiles naturally form a honeycomb pattern, but slight variations in placement can disrupt the visual flow. Use tile spacers specifically designed for hexagons, typically placed at the tile’s corners. These spacers ensure uniform grout lines, usually 1/16 to 1/8 inch wide. Periodically step back to inspect the alignment, using a level or straight edge to verify straight lines. Adjust tiles as needed before the mortar sets, typically within 15–20 minutes. This attention to detail prevents uneven grout lines and ensures the pattern remains symmetrical.
A practical tip for setting hexagon tiles is to work in small sections, especially for beginners. Start at the center of the wall or a focal point and expand outward. This approach allows you to establish a consistent pattern and make adjustments without disturbing previously laid tiles. For shower walls, begin at the bottom row and work upward, ensuring each tile is level and aligned with the row below. Use a tile nipper to trim tiles as needed for edges or corners, maintaining the integrity of the pattern. Patience and precision in this stage pay off in the final result.
While pressing tiles into the mortar, be mindful of the pressure applied. Too much force can cause the mortar to squeeze out unevenly or push tiles out of alignment, while too little may result in inadequate adhesion. Aim for firm, even pressure, pressing each tile until it sits flush with its neighbors. Wipe away excess mortar immediately with a damp sponge to prevent it from drying on the tile surface. This step not only keeps the tiles clean but also ensures grout adheres properly later. Balancing pressure and cleanliness is key to a seamless installation.
Finally, consider the mortar’s working time, typically 30–60 minutes depending on the product. Plan your work pace to stay within this window, as mortar that begins to set becomes difficult to adjust. If you’re working in a humid environment, such as a bathroom, the mortar may set faster, so prepare accordingly. Once the tiles are set, allow the mortar to cure for at least 24 hours before grouting. This curing time ensures the tiles are fully bonded and ready for the next step. With careful placement and attention to detail, setting hexagon tiles becomes a manageable task that elevates the overall design of your shower wall.

Grout and seal: fill gaps with grout, clean excess, and apply sealer to protect tiles
Grout is the unsung hero of tile installation, transforming a collection of individual hexagons into a cohesive, watertight surface. Its primary function is to fill the gaps between tiles, preventing water infiltration and providing structural stability. When installing hexagon tiles on a shower wall, choosing the right grout type is crucial. Epoxy grout, known for its stain and water resistance, is ideal for wet areas like showers. Unlike cementitious grout, epoxy doesn’t require sealing and is less prone to cracking, making it a superior choice for long-term durability.
Once the grout is mixed to a smooth, toothpaste-like consistency, apply it diagonally across the tiles using a rubber float. Press the grout firmly into the joints, ensuring it fills the gaps completely. Work in small sections to avoid drying before completion. After the grout sets slightly but is still pliable (typically 15–20 minutes), use a damp sponge to wipe away excess grout from the tile surfaces. Be gentle to avoid pulling grout from the joints. Repeat this process until the tiles are clean, changing the sponge water frequently to avoid smearing.
Cleaning excess grout is an art as much as a science. Too much pressure can dislodge grout from the joints, while too little leaves a haze that’s difficult to remove later. A pro tip is to hold the sponge at a low angle and use circular motions to lift the grout without disturbing the joints. Allow the grout to cure for 24–48 hours before proceeding to the next step. This curing time is essential for the grout to reach its full strength and adhesion.
Sealing the grout is the final step in protecting your hexagon tile shower wall. Even epoxy grout, which is inherently water-resistant, benefits from a sealer to guard against soap scum, mildew, and minor stains. Apply a penetrating grout sealer using a small brush or applicator bottle, ensuring it saturates the grout lines. Wipe away any excess sealer from the tile surfaces immediately with a clean cloth. Reapply the sealer annually or as needed, depending on usage and wear.
The combination of proper grouting and sealing not only enhances the aesthetic appeal of your hexagon tiles but also ensures their longevity in a high-moisture environment. Skipping these steps or cutting corners can lead to water damage, mold growth, and costly repairs down the line. By investing time and care into grouting and sealing, you’ll create a shower wall that’s as functional as it is beautiful.
