How to Lay Subway Tile in Shower
To lay subway tile in your shower, start by gathering durable tiles, adhesive, grout, and tools. Clean and prep your walls, ensuring they’re smooth and waterproof. Plan your tile layout with level guidelines, then mix and apply thinset mortar in small sections. Press tiles firmly, using spacers and checking for level as you work. Once set, grout and seal for moisture protection. Keep going to discover tips on cutting tiles and achieving a flawless finish.
Gather Necessary Tools and Materials
Before you begin laying subway tile in your shower, you’ll need to gather all the essential tools and materials. Start with quality subway tiles—choose ceramic or porcelain for durability.
Get tile adhesive or thin-set mortar suitable for wet areas. You’ll also need grout to fill gaps between tiles, plus a grout sealer to protect it from moisture.
Equip yourself with a notched trowel to spread adhesive evenly, a tile cutter or wet saw for precise cuts, and a rubber grout float for applying grout.
Don’t forget spacers to ensure consistent gaps between tiles and a sponge for cleaning excess grout. Safety gear like gloves and goggles is important too.
Having these ready will make your tiling project smoother and more efficient.
Prepare the Shower Surface
Since a properly prepared surface ensures your tiles adhere well and last longer, you’ll want to start by cleaning the shower walls thoroughly. Remove any soap scum, dirt, or mildew using a strong cleaner or a mixture of vinegar and water. After cleaning, rinse and let the walls dry completely.
Next, inspect the surface for damage like cracks or loose drywall. Repair any imperfections with a waterproof patch or thin-set mortar to create a smooth, stable base.
If your shower walls aren’t water-resistant, install cement backer board to prevent moisture issues.
Finally, apply a primer or bonding agent recommended for tile installation to improve adhesion. Taking these steps ensures your subway tiles will stick firmly and maintain their appearance over time.
Plan Your Tile Layout
Although it might be tempting to start tiling right away, you’ll save time and headaches by carefully planning your tile layout first. Begin by measuring the shower walls to determine how many subway tiles you’ll need. Use a pencil and level to draw horizontal guidelines on the wall, starting at the center or a focal point to ensure symmetry.
Dry-lay a row of tiles on the floor to visualize spacing and cuts. This helps avoid awkward partial tiles at corners or edges. Consider grout line widths and how they affect the overall look. Adjust your starting point if necessary to maintain balance across the walls.
Taking these steps upfront ensures a professional, clean finish and reduces tile waste.
Mix and Apply Thinset Mortar
With your tile layout planned and guidelines in place, you’re ready to prepare the thinset mortar that will hold your subway tiles securely to the shower wall. Start by emptying the thinset powder into a clean bucket. Slowly add water while mixing with a margin trowel or a drill with a paddle attachment.
Aim for a peanut butter-like consistency—smooth and spreadable, but not too runny. Let it slake for 5 to 10 minutes, then remix briefly before using.
Apply the thinset to the wall with the flat side of a notched trowel, spreading it evenly. Hold the trowel at a 45-degree angle to create ridges that improve adhesion.
Work in manageable sections to prevent the thinset from drying out before you set your tiles.
Set the Subway Tiles
Before you start placing each subway tile, press it firmly into the thinset and give it a slight twist to ensure a strong bond.
Begin at the bottom center of your shower wall, working outward and upward.
Use tile spacers between each tile to maintain even grout lines and consistent spacing.
Keep checking your level frequently to ensure the tiles stay straight and aligned.
If you notice any tiles sitting too high or low, gently adjust them before the thinset sets.
Continue layering tiles row by row, staggering the joints like a brick pattern for a classic subway tile look.
Take your time to keep the rows straight and the spacing uniform, which will make grouting easier and give your shower a professional finish.
Cut Tiles to Fit Edges and Corners
How do you handle tiles that don’t fit neatly at edges and corners? You’ll need to measure carefully and cut tiles to size.
First, mark the tile where it needs trimming using a pencil and a straightedge. For straight cuts, use a tile cutter to snap the tile cleanly.
When dealing with curved or irregular cuts, a wet saw or tile nippers will give you more control. Always wear safety goggles when cutting.
Take your time to ensure cuts are precise, as poorly cut tiles can affect the overall look. Dry-fit each cut tile before applying mortar to confirm it fits perfectly.
This attention to detail ensures your subway tile layout remains seamless and professional, even in tricky spots like edges and corners.
Allow Mortar to Cure
Once you’ve set all the tiles in place, you need to let the mortar cure properly to ensure a strong bond. Avoid disturbing or moving the tiles during this time. Typically, curing takes about 24 to 48 hours, but check the manufacturer’s instructions for exact timing.
Keep the area dry and well-ventilated to help the mortar harden evenly. Don’t rush this step; premature handling can weaken the adhesion and cause tiles to loosen later. If your bathroom is humid, consider using a fan or dehumidifier to speed up drying.
After the curing period, test a small area gently to ensure the tiles are firmly set. Only once the mortar is fully cured should you proceed with grouting and sealing.
Apply Grout and Seal the Tiles
After the mortar has fully cured, you can apply grout to fill the gaps between the subway tiles. Mix the grout according to the manufacturer’s instructions until it reaches a smooth, peanut butter-like consistency.
Using a rubber float, spread the grout diagonally across the tiles, pressing it firmly into the joints. Work in small sections to avoid the grout drying out before you can clean it.
Once applied, wait about 10-15 minutes, then wipe the tile surface with a damp sponge to remove excess grout, rinsing the sponge frequently.
After letting the grout cure for the recommended time, apply a grout sealer to protect it from moisture and stains. This step is crucial in a shower to maintain durability and keep your tile looking fresh.
Frequently Asked Questions
Can I Install Subway Tile in a Steam Shower?
Yes, you can install subway tile in a steam shower, but you’ll need waterproof backer board and a high-quality waterproof membrane to prevent moisture damage. Also, use steam-rated grout and sealant to ensure durability and prevent mold growth.
How Do I Prevent Mold Behind the Tiles?
You prevent mold behind tiles by waterproofing the wall with a vapor barrier or waterproof membrane, ensuring proper ventilation, using mold-resistant grout and caulk, and sealing all joints tightly to keep moisture from seeping behind the tiles.
What Tile Pattern Is Best for Small Showers?
You’ll want to use a classic subway or vertical stack pattern in small showers. These patterns create clean lines and make the space feel larger. Avoid busy layouts that can overwhelm the limited area.
