What Is Subway Tile? A Complete Guide to the Classic Tile Style

Subway tile is a rectangular tile style inspired by the glazed ceramic tiles installed in early New York City subway stations. Traditional subway tile measures 3 x 6 inches, although today's subway tiles come in many sizes, materials, colors and finishes.

When someone asks me what subway tile is, I usually explain that it is better understood as a tile style than one specific product. The classic version is a glossy white ceramic rectangle, but modern subway tile can be made from ceramic, porcelain, glass, natural stone and other materials.

That versatility is one reason subway tile continues to be used in kitchens, bathrooms, showers and other tiled spaces. You can keep the traditional look or change the size, color, material, finish and layout to create something completely different.

In this guide, I'll explain what defines subway tile, where the name came from, what subway tiles are made of and what to consider when choosing one for your project.

What Is Subway Tile?

Subway tile is a rectangular tile format traditionally associated with white glazed ceramic tiles measuring approximately 3 x 6 inches. The rectangular shape and roughly 1:2 proportion became one of the most recognizable tile styles in American interiors.

Today, the term is much broader. A subway tile does not have to be white, ceramic or exactly 3 x 6 inches. You'll find longer formats, smaller rectangles, glass subway tile, porcelain, stone, textured surfaces, matte finishes and colors ranging from subtle neutrals to deep blues and greens.

The common thread is the elongated rectangular form and the visual connection to the classic subway-tile aesthetic.

Why Is It Called Subway Tile?

Subway tile gets its name from the ceramic tiles associated with early underground transit stations, most famously the New York City subway system that opened in 1904.

The original station interiors used durable glazed tile surfaces that were practical for busy public spaces. Light-colored glazed surfaces also helped create a bright, clean appearance in underground stations where natural light was limited.

Over time, the rectangular white tile became strongly associated with subway architecture. The look eventually moved beyond transit stations and into residential kitchens, bathrooms and other interiors.

That history is why a relatively simple rectangle is still referred to as "subway tile" more than a century later.

What Are Subway Tiles Made Of?

Traditional subway tiles were ceramic, but modern subway tile is available in several materials. The material matters because it affects appearance, maintenance, installation and where a particular tile can be used.

Ceramic Subway Tile

Ceramic is the material most closely associated with traditional subway tile. It is available in an enormous range of colors, finishes and surface treatments and remains a popular option for interior walls.

Our ceramic subway tile collection is a good place to see how far the style has evolved beyond basic white 3 x 6 tile.

Glass Subway Tile

Glass gives subway tile a different character. Depending on the product, glass can introduce clarity, depth, reflectivity and more saturated color than traditional ceramic.

It is particularly popular on kitchen backsplashes and decorative walls. You can compare these styles in our glass subway tile collection.

Porcelain Subway Tile

Porcelain provides another interpretation of the rectangular subway format. Because performance characteristics vary by product, always check the manufacturer's specifications for the exact tile and application you are considering.

Natural Stone Subway Tile

Marble and other natural stones can also be cut into subway-style rectangles. Stone introduces natural veining, color variation and texture that make each installation less uniform than traditional glazed ceramic.

Natural stone also has different sealing and maintenance considerations, so the material should be selected for more than appearance alone.

What Size Is Traditional Subway Tile?

The traditional subway tile size is 3 x 6 inches. That classic 1:2 proportion is still what many people picture when they hear "subway tile."

But 3 x 6 is no longer the only subway tile size. Modern collections include narrower, longer and larger rectangular formats such as 2 x 6, 3 x 12 and 4 x 12.

Changing the dimensions can significantly change how an installation feels. A smaller rectangle can create more grout lines and visual rhythm, while an elongated format can produce a cleaner, more contemporary appearance.

Because size is its own subject, we cover subway tile dimensions and choosing between different formats separately rather than trying to turn this definition guide into a complete sizing guide.

Types of Subway Tile

When homeowners talk about different "types" of subway tile, they may be referring to the material, edge treatment, surface finish, color or dimensions.

Some of the most common variations include traditional glossy ceramic, matte ceramic, glass, porcelain, marble and other natural stone, beveled-edge tile, handmade-look surfaces and elongated rectangles.

Flat vs. Beveled Subway Tile

A traditional flat subway tile has a relatively straightforward face. A beveled subway tile has angled edges that create additional depth and shadow.

That seemingly small detail can make a major visual difference. Beveled edges emphasize each individual tile, while a flat face generally creates a smoother overall field.

Glossy vs. Matte Subway Tile

Glossy subway tile reflects more light and tends to emphasize color and surface variation. Matte finishes create a softer appearance with less reflection.

Neither finish is universally better. I choose between them based on the room, surrounding materials and the overall design rather than treating one as the default.

Where Can Subway Tile Be Used?

One reason subway tile has lasted so long is that the basic rectangular format works in many parts of the home. The important distinction is that not every subway tile is approved for every application. Always verify the specifications for the exact product.

Kitchen Backsplashes

The kitchen backsplash is probably the application most homeowners associate with subway tile today. The rectangular format works with traditional, transitional and contemporary kitchens, while the material and color can completely change the personality of the installation.

If you're shopping specifically for a backsplash, our kitchen backsplash tile collection includes subway tile along with other mosaic and field-tile options.

Bathrooms

Subway tile works especially well on bathroom walls because the rectangular format can adapt to large expanses, vanity backsplashes, tub surrounds and accent areas.

Changing the color, dimensions or orientation can make a bathroom feel very different without abandoning the basic subway shape.

Shower Walls

Many subway tiles can be used on shower walls when the specific product is approved for wet applications and installed over an appropriate waterproofed substrate.

For shower applications, start with tile specifically suited to the location rather than assuming every subway tile has the same performance characteristics. Our shower wall tile collection can help narrow the options.

Other Walls and Feature Areas

Subway tile can also work on laundry-room walls, wet bars, fireplace surrounds and decorative feature walls when the chosen product is appropriate for that application.

Is Subway Tile Still in Style?

Subway tile has not disappeared from interior design, but the way it is being used continues to evolve.

The classic white 3 x 6 ceramic installation is only one option. Longer formats, handmade-looking surfaces, saturated colors, warm neutrals, glass, natural stone and different layouts can make the rectangular subway format feel very different from the traditional version.

This is one reason I don't think of subway tile as a single trend. The rectangle is simply the foundation. The material, color, finish, grout and layout determine whether the finished room looks traditional, contemporary, industrial, coastal or somewhere in between.

If you're concerned about creating a dated installation, I would focus less on whether the words "subway tile" are currently fashionable and more on whether the specific tile works with the permanent materials and architecture of your room.

How to Choose Subway Tile

I start with the application before I start with color. A tile that looks great on a computer screen still has to be appropriate for the wall, shower, backsplash or other location where you intend to install it.

Once you've confirmed application suitability, consider four major design variables: material, size, finish and color.

Material determines much of the character and maintenance of the tile. Size changes the visual scale of the installation. Finish controls how the surface interacts with light. Color determines how strongly the tile connects or contrasts with cabinets, countertops, flooring and fixtures.

Grout deserves consideration at the same time. A grout color close to the tile tends to make the installation read more continuously, while greater contrast emphasizes the rectangular shape and layout.

Finally, order a sample whenever possible. Color, reflectivity, texture and scale are much easier to judge in the actual room than from a screen.

Mike's Take on Subway Tile

What I like about subway tile is that the shape doesn't force you into one particular design style. A white ceramic 3 x 6, a long blue glass rectangle and a marble subway tile can all share the same basic geometry while producing completely different rooms.

That's also why I recommend choosing the actual tile first and worrying about the label second. Look at the material, finish, dimensions and application rating. Those details matter much more than whether a product fits someone's narrow definition of what subway tile is supposed to look like.
