What is a Subway Tile?

At first glance, subway tile might seem straightforward—a simple, rectangular tile. However, its cultural roots, design evolution, and enduring popularity tell a much richer story. Born in 1904 within the walls of New York City’s first subway station, this tile was initially chosen not just for its appearance, but for its hygiene benefits. The glossy white surface was easy to clean and reflected artificial light, brightening otherwise dim underground spaces.

From its utilitarian beginnings, subway tile quickly made the leap into residential and commercial interiors. Architects and designers embraced it not only for its cleanliness but also for the understated elegance it brought to a space. Over time, subway tile became synonymous with a variety of styles, from vintage revival to contemporary minimalism.

Its staying power lies in its balance of familiarity and flexibility. Few other tile styles have achieved such versatility while remaining instantly recognizable.

 

Durability of Subway Tile for Floors

The allure of subway tile's timeless aesthetics can be tempting for flooring applications. However, before committing, a deep dive into its durability for busy areas is crucial. Here's a breakdown of the key factors impacting subway tile's performance on floors:

Thickness

Standard subway tiles, typically measuring around 3/8" thick, are designed for wall applications. Their relative thinness makes them susceptible to cracking under several scenarios:

Heavy Foot Areas

Constant pressure from footsteps, especially in most-used areas like hallways or kitchens, can cause hairline cracks to develop over time. These cracks not only detract from the visual appeal but can also trap dirt and moisture, leading to potential grout problems.

Point-Load Pressure

Furniture with concentrated weight points, like dressers or bookcases, can exert significant pressure on a small area of the tile. This point-load pressure can cause the tile to chip or even crack if the subfloor isn't properly prepared for such stress.

Material

Both ceramic and porcelain are common materials for subway tile, but their composition and resulting durability differ:

Ceramic

Made from fired clay, ceramic tiles offer a budget-friendly and widely available option. They are generally less dense and more prone to chipping or scratching than porcelain, which can make them less ideal for busy floors. However, for wall applications or lightly used flooring areas, such as powder rooms or decorative inlays, ceramic tiles can be a stylish and practical choice.

A great example is Edward Martin’s Graham 3x6 Glossy Ceramic Tile in Bone, as shown in the photo above. With its warm neutral tone and smooth glossy finish, this tile provides timeless appeal and effortless elegance for spaces where impact and moisture levels are moderate. It’s especially well-suited for bathrooms, accent floors, or areas where classic design is a priority.

Porcelain

Porcelain, on the other hand, is fired at higher temperatures and made from more refined clay. The result is a denser, more durable tile that resists moisture, scratches, and general wear more effectively than standard ceramic. These qualities make porcelain a preferred choice for floor installations, especially in areas like kitchens, entryways, and bathrooms where durability is essential.

A prime example is the Catalina 2x16 Matte Porcelain Tile in Cream. Its extended format and soft matte finish lend a modern, seamless look that works beautifully on floors. The creamy neutral tone adds warmth and versatility to a range of design styles, while the porcelain construction ensures dependable performance in everyday environments.

When selecting subway tile for floors, prioritizing porcelain options specifically rated for floor use will provide greater longevity and visual consistency across the life of the installation.

Glaze

Glazing refers to the outer coating applied to the surface of a tile, which significantly affects both its performance and appearance. The glaze type plays a vital role in determining how suitable a subway tile is for floor use, particularly in areas exposed to moisture or heavy wear.

Glazed

Glazed ceramic or porcelain tiles feature a layer of liquid glass that is fused to the tile's surface during firing. This provides a smooth, non-porous barrier that helps resist stains, moisture, and bacteria. Glazed subway tiles are easier to clean and maintain, making them a practical choice for kitchens and bathrooms. However, depending on the finish (e.g., glossy), they may become slippery when wet.

Unglazed

Unglazed tiles, in contrast, do not have a surface coating. This leaves the raw ceramic or porcelain exposed, offering a more natural, earthy texture. Unglazed tiles are generally more slip-resistant due to their rougher surface, making them a good option for busy or wet areas. However, they are more prone to staining and may require sealing for moisture protection.

Tile Finishes

Beyond glazing, the finish of a tile influences not just its look, but also its slip resistance, light reflectivity, and how it feels underfoot. Here's a breakdown of common subway tile finishes:

Glossy

A high-shine finish that reflects light and brightens spaces. Glossy tiles have a sleek, modern look but can be slippery when wet, so they are best reserved for walls or low-activity floors where moisture isn’t a concern.

Matte

This low-sheen finish offers a soft, muted appearance with increased traction, making it an ideal choice for bathroom and laundry room floors. Matte finishes are also more forgiving with smudges and water spots compared to glossier options.

Polished

Achieved through mechanical buffing, this finish is highly reflective and smooth to the touch. While it adds luxury and elegance, polished surfaces can be slippery and may show scratches more easily, so they are generally recommended for decorative use or low-activity areas.

Satin

Sitting between glossy and matte, satin finishes provide a subtle sheen with a smooth feel. They balance aesthetics and practicality by offering moderate light reflection and reasonable slip resistance, making them suitable for various floor applications.

Crackled

This finish features a fine web of surface cracks in the glaze, creating a vintage or antique appearance. While visually distinctive, crackled finishes are more porous and typically require sealing to prevent moisture intrusion, especially when used on floors.

Additional Considerations for Durability

Beyond the factors mentioned above, a few additional details influence the durability of subway tile for floors:

PEI Rating

The Porcelain Enamel Institute (PEI) rating system classifies ceramic and porcelain tiles based on their wear resistance. For moderate to heavy use areas, choose a tile with a PEI rating of at least 3. A higher rating indicates greater suitability for frequently used applications.

Grout Selection

The grout, the material filling the gaps between tiles, plays a role in durability. Opt for a non-sanded grout, which offers a smoother surface for easier cleaning and less chance of harboring dirt or bacteria. Regularly sealing the grout helps prevent moisture absorption and reduces the risk of cracking.

By carefully considering these factors, you can make an informed decision about whether subway tile is the right choice for your flooring project. Remember, prioritizing durability, especially in busy areas, is essential for a long-lasting and beautiful floor.

 

 

Safety Considerations for Subway Tile Floors

Safety is paramount, especially in areas prone to moisture like bathrooms and laundry rooms. Here's a detailed breakdown of key considerations to ensure your subway tile floor is beautiful and functional:

Slip Resistance

When considering subway tiles for busy or wet areas, slip resistance is a crucial factor to ensure safety. The coefficient of friction (COF) is a key metric to evaluate; tiles with a COF rating of 0.8 or higher are recommended for wet environments like bathrooms and laundry rooms, as they offer better slip resistance. Additionally, the tile finish plays a significant role—glazed subway tiles, while sleek, can be very slippery when wet. Opting for matte or textured finishes can provide more traction underfoot.

A great example is Edward Martin’s Catalina 2x16 Matte Porcelain Tile in Cotto, which combines a slip-resistant matte surface with the strength of porcelain. Its elongated format and earthy Cotto tone make it a stylish yet practical choice for wet zones where both safety and visual warmth are priorities. Whether used in bathrooms, laundry rooms, or transitional indoor-outdoor spaces, this tile provides peace of mind without sacrificing design appeal.

Tile material also impacts slip resistance. While ceramic and porcelain are popular choices, exploring stone-look porcelain tiles with textured surfaces can offer the natural slip resistance of some stones. To enhance safety further, consider using non-slip area rugs near exits from showers, bathtubs, and laundry sinks. Rugs with a rubber backing can help prevent slips by staying securely in place on the tile floor.

Grout Lines

When selecting grout for subway tiles in high-moisture areas, such as bathrooms and kitchens, several factors play a crucial role in both functionality and safety. Grout type is important; non-sanded grout is generally preferred for its smoother texture, which provides better traction compared to sanded grout with larger pores that can become slippery when wet.

Grout color also affects both aesthetics and maintenance. While dark-colored grout can look appealing, it may show water stains more prominently. A lighter-colored grout can hide water marks better, making it a practical choice for areas exposed to frequent moisture.

Additionally, grout sealing is essential. Regularly applying a high-quality penetrating sealer helps prevent water absorption, reduces the risk of mold growth, and maintains the grout's integrity. Unsealed grout can become slippery and deteriorate over time, potentially creating uneven surfaces that increase the risk of slips and falls.

Additional Considerations

When choosing and installing subway tiles, it’s essential to consider additional factors that impact both safety and functionality.

Slope

In shower areas, ensure the floor slopes slightly towards the drain to allow for proper water drainage. This helps prevent water from pooling on the surface, minimizing the risk of slips.

Lighting

Proper lighting in bathrooms and laundry rooms is crucial for safety. Ensure adequate task lighting near showers, bathtubs, and laundry sinks to improve visibility and prevent slips caused by poor lighting conditions.

Maintenance

Regularly clean your subway tile floor using appropriate cleaning products. Avoid using harsh chemicals or abrasive cleaners that can damage the tile surface and make it more slippery.

By prioritizing safety considerations when choosing and installing subway tiles, you can create a beautiful and functional floor that complements your home's aesthetics without compromising safety.
