The Iconic Journey Of Subway Tiles

In 1904, architects George C. Heins and Christopher Grant La Farge designed the New York subway station, introducing the now-iconic 3 x 6″ ceramic tiles. These versatile subway tiles have since found their way into a wide range of public spaces, from hospitals to schools.

In recent years, subway tiles have surged in popularity for residential use. Their clean and classic look seamlessly blends with any design style, making them a versatile choice. Not to mention, these ceramic or porcelain tiles are cost-effective and easy to install, making them an attractive option for DIY enthusiasts.

If you're contemplating a subway tile backsplash for your space, you're tapping into a trend that's here to stay. The timeless, minimalistic appeal of subway tiles resonates with many, offering a sleek and sophisticated look. One of the best things about subway tiles is also their accessibility. Unlike other backsplash options like mosaic or glass, subway tiles don’t require any special tools or training for installation. This makes them perfect for those who enjoy taking on improvement projects themselves.

Creative Ideas For Subway Tile Backsplash

Traditionally, subway tiles are laid out in a straightforward, horizontal arrangement. However, there's plenty of room to get creative with your tile installation. Why not try a herringbone pattern or mix and match different tile sizes for a visually captivating effect? You can even experiment with vertical or diagonal installations to add a unique twist to your design.

One stunning example of creative installation is shown in the image above, where the backsplash features a refined herringbone layout using our Catalina 2x16 Matte Porcelain Tile in Clay. The earthy, terracotta-inspired hue adds depth and richness to the kitchen, complementing the wood accents and natural textures throughout the space. The elongated format gives this subway tile a modern twist, while the matte finish offers a grounded, artisan feel that elevates the overall aesthetic.

Consider playing with color as well. Although classic white subway tiles offer a clean and timeless look, don’t be afraid to explore bold colors. These choices can make your backsplash a standout feature in your kitchen or bathroom.

Texture is another element to think about. Glossy subway tiles can reflect light and make a space feel larger, while matte tiles offer a more subdued, sophisticated look. You can also mix textures within your design for added depth and interest.

Once you've envisioned the look you're going for, it’s time to start your tile hunt! The market is brimming with various types of subway tiles, so enjoy the process of selecting the perfect ones for your space. Be sure to consider the size, color, texture, and finish to find the perfect match for your aesthetic.

When you’re ready to begin the installation, just follow the straightforward steps below. Subway tile installation is a manageable project for most DIYers, and with a bit of planning and patience, you'll have a stunning new backsplash in no time.

Installing Subway Tile Backsplash

Installing a subway tile backsplash can elevate your space with a clean, timeless look, and it's a project many DIYers can tackle with the right guidance. This step-by-step overview offers general best practices, but be sure to follow any specific instructions provided by your tile manufacturer or consult a professional for more complex installations.

Take Measurements

First, assess the space where you intend to install the backsplash and figure out how many subway tiles are necessary. Remember to include grout, thin-set mortar, and spacers in your shopping list. For beginners, it's wise to buy a few extra tiles in case of mistakes or future replacements. Having all your materials ready before starting makes the process much smoother.


Wall Preparation

Clear the wall of any old backsplash, wallpaper, or debris before getting started. The surface should be clean, dry, and flat for the adhesive to bond properly. If needed, sand or vacuum the area to remove dust and texture. You can sometimes tile over existing surfaces, but only if they’re in solid condition.


Applying Adhesive

Begin applying adhesive in small sections, starting from one corner and working your way out. Use a notched trowel to spread the thin-set evenly, forming grooves to improve adhesion. Don’t rush; consistency in the adhesive layer helps keep tiles level. Be sure to follow the adhesive's open time to avoid reapplication.


Setting the Tiles 

Press each subway tile firmly into the adhesive, starting from your reference point and working outward. Use tile spacers to ensure uniform grout lines and cut tiles carefully to fit around edges or outlets. Check for levelness as you go, adjusting where needed. Once done, let the adhesive cure fully, usually for 24 hours.


Grouting the Tiles

Once the adhesive is dry, it’s time to apply grout across all joints using a grout float. Work in sections and wipe away excess grout from the surface before it dries. Use a damp sponge to smooth lines and remove haze as you go. Let the grout set according to the manufacturer’s instructions, then polish with a soft cloth if needed.

Subway Tile Spacer Tips

Using spacers will ensure even, consistent joints when you lay subway tiles. We recommend opting for tile spacers that are at least ¼” wide. These spacers will help maintain uniform gaps between the tiles, making the grouting process easier and ensuring a professional-looking finish.

Choosing the right size spacer is also crucial for both aesthetics and functionality. Too small spacers can make the grout lines appear uneven, while larger spacers provide a more defined and polished look. By using ¼” spacers, you'll achieve a balanced appearance that enhances the overall design of your tile installation. However, it's always best to follow the manufacturer's recommendations or any specific installation advice to ensure the best results for your particular project.

Drying Time For Your Subway Tile Backsplash

It’s important to factor in drying time for each step of the process. Rushing ahead without allowing the adhesive or grout to fully cure can compromise the quality of your backsplash.

Although it can be tempting to move quickly from one stage to the next, resisting that urge will pay off. Taking the time to do things right from the start helps ensure your backsplash is both durable and professionally finished. In short, patience during the drying phases is just as important as precision during installation. Give each layer the time it needs to set properly, and you’ll be rewarded with a beautiful, long-lasting result.

That said, not all drying times are the same. They can vary based on the materials you’re using and environmental factors like humidity and temperature. For most tile adhesives, a minimum of 24 hours is recommended to ensure a strong bond with the wall. Grout typically requires a similar amount of time to cure and reach full strength. Always check the manufacturer’s instructions for product-specific guidance.

Failing to follow these timelines can lead to preventable issues. Subway tiles may shift, grout can crack, and the overall integrity of your backsplash could suffer. Allowing each step to dry properly is one of the simplest ways to ensure your finished project looks great and lasts. Remember, great results take time, and your backsplash deserves that care.

Importance Of Caulking

One last factor to keep in mind is caulking. Caulking acts as a sealant that fills in gaps and cracks, ensuring a polished and secure finish. Apply it around the perimeter of your backsplash, as well as any areas where two different surfaces meet, such as where the backsplash meets the countertop.

In the photo above, the deep, rich blue tile of our Natasha 2x6 Matte Porcelain Tile in Denim adds bold, modern character to a warm wood-accented kitchen. Using caulk where the subway tile meets the counter or cabinetry ensures this clean-lined look stays crisp and protected over time. Furthermore, the blue color provides a dramatic yet sophisticated backdrop, and proper caulking around the edges helps maintain the integrity of both the design and the installation.

Caulking also helps create a watertight seal that keeps your backsplash looking great for years to come. By preventing water and debris from seeping into gaps, caulking preserves the integrity of your installation and enhances its longevity. Make sure to choose a high-quality, mold-resistant caulk for the best results. Although this is a general suggestion, it's always best to follow the manufacturer's recommendations for your specific product and installation needs.

Preserving Your Subway Tile Backsplash

Once your subway tile backsplash is installed, proper care is essential to maintain its beauty and durability. Establishing a regular cleaning routine is the first step. For ceramic or porcelain subway tiles, a mild, pH-neutral cleaner paired with a soft cloth or sponge is ideal for removing everyday splashes, grease, and dust without dulling the surface.

Equally important is what to avoid. Steer clear of harsh chemicals, acidic solutions, or abrasive scrubbing pads, as these can damage the glaze or finish over time. For grout lines, using a soft-bristled brush occasionally can help keep them clean without compromising their structure.

In busy areas like kitchens, preventive habits go a long way. Wipe down spills promptly to avoid staining, and consider resealing grout periodically if your tile setup requires it. These simple practices not only protect your tile but also preserve the aesthetic appeal of your backsplash.

By taking these small but consistent steps, your subway tile will continue to look pristine and vibrant, adding value, charm, and longevity to your space. As always, refer to the subway tile manufacturer’s care and maintenance guidelines to ensure your backsplash stays in top shape for years to come.

Frequently Asked Questions About Subway Tile Backsplashes

Whether you're diving into your first DIY tile project or refining your design choices, subway tile backsplashes raise a few common questions beyond the basics. Below are answers to some frequently asked questions that can help you plan, execute, and enjoy your backsplash installation with greater confidence.


1. Can I install subway tile directly over drywall or painted walls?

Yes, you can install subway tile over clean, dry, and properly primed drywall or painted surfaces, as long as they are smooth and in good condition. However, high-moisture areas (like behind a sink or range) may benefit from using a cement backer board for added durability and moisture resistance.


2. Do I need to seal subway tile?

Ceramic and porcelain subway tiles are glazed and don’t require sealing. However, if you’re using unglazed tile, natural stone, or a porous finish, applying a tile and grout sealer is recommended to protect against stains, moisture, and discoloration.


3. What type of tile cutter is best for subway tile?

For straight cuts on ceramic or porcelain subway tiles, a manual tile cutter works well. For more precise or intricate cuts such as L-shapes around outlets or corners, a wet saw with a diamond blade is the preferred tool, especially for larger or harder tiles.


4. How do I transition between subway tile and painted wall?

To create a clean and professional transition, consider using a trim piece like a bullnose tile, metal edge trim (such as Schluter), or a simple caulk line that matches the grout color. These options help visually define the end of the tile and protect exposed edges.


5. Can I mix subway tile with other tile shapes in the same space?

Absolutely. Mixing subway tile with hexagon, square, or even mosaic tiles can add depth and personality to your design. Just be sure to balance color, finish, and scale to maintain a cohesive look throughout the space. To help you visualize how different tile shapes and layouts will look together in your actual space, try using our augmented reality (AR) tool. It allows you to preview tile combinations in real time, making it easier to experiment with bold ideas before committing to a final design.
