What Is Subway Tile?

Rectangular. Twice as wide as it is tall. Laid in a brick-style offset. That combination is subway tile, and it has been the default backsplash choice on more Nanaimo and Courtenay kitchens than any other single product we install. Most homeowners can picture it before they can name it, which tells you something about how far the look has travelled from where it started.

Standard size runs 3×6 inches, though the category now covers anything with a roughly 1:2 ratio, from a small 2×4 mosaic strip to an elongated 3×12 plank. Ceramic remains the most common material, but glass, porcelain, marble, and natural stone versions all get sold under the same name.

Where the Name Actually Comes From

New York City, 1904. Architects Heins and La Farge needed a wall surface for the first subway stations that would feel clean and bright to riders nervous about going underground for the first time. White glazed ceramic tile, laid in that now-familiar offset, reflected what light there was and wiped clean easily. The name stuck to the tile long after most people stopped thinking about subway platforms.

Germ theory was gaining ground in that era too, and a smooth, non-porous, easy-to-scrub surface fit the moment. Hospitals, commercial kitchens, and eventually home bathrooms adopted the same tile for the same reason. Over a century later, the practical case still holds up, even though most homeowners choosing it today care more about the look than the hygiene argument that started it.

The Standard Sizes and Where Homeowners Deviate

3×6 inches is still the most requested size on our jobs, and it’s the one people mean when they say “subway tile” without qualifying it further. Beyond that, the sizing gets flexible fast. 2×4 works well for a small backsplash where a person wants more grout lines and more visual texture. 4×8 and 6×12 scale the same brick pattern up for a shower wall or a larger kitchen run. 3×12 has become popular on Island jobs the last few years, a longer, thinner plank that reads more modern and needs fewer cuts around outlets.

Grout joint width matters more than people expect going in. 1/16 inch is standard on a factory-edge 3×6, tight enough that the offset pattern reads clean without the grout lines competing for attention. Handmade or slightly irregular tile needs 1/8 inch or more just to accommodate the size variation between individual pieces, and skipping that step is one of the more common callback causes we see on DIY jobs.

Material Options

Ceramic is where subway tile started and it’s still the budget-friendly default. Handles moisture fine in a kitchen backsplash, less ideal for a full shower surround where impact resistance matters more.

Porcelain costs more but wins on water absorption, which is the number that actually matters in a wet shower install. We push clients toward porcelain any time the tile is going somewhere it will see standing water or steam on a daily basis.

Glass brings a glossier finish and a wider colour range, but it scratches more visibly over time and shows trowel ridges through a translucent face if the installer isn’t careful with technique. Marble and natural stone versions look striking and cost the most, plus they need sealing that ceramic and porcelain never require.

What We Actually Recommend

Porcelain for anything wet. Ceramic for a dry kitchen backsplash where budget matters. Marble only for clients who understand the sealing commitment going in, because the ones who skip that maintenance call us back within two years asking why the grout has gone grey.

Pattern Options Beyond the Standard Offset

Traditional layout uses a 50% offset, the middle of each tile lined up with the seam of the two tiles above and below it. That’s the pattern most people picture. A 1/3 offset shifts the stagger slightly, a subtle variation that reads as intentional rather than accidental once it’s on the wall. Push the stagger to a 1/4 offset and the wall gets a stepped, almost staircase feel running up it.

Herringbone has become the request we hear most often for a feature wall or a statement backsplash behind a range. It takes longer to install, involves diagonal cuts around every outlet and edge, and costs more in labour for exactly that reason. Vertical stacking, tiles set directly on top of each other with no offset at all, elongates a narrow wall and reads more contemporary than the brick pattern most people associate with the name.

Where Subway Tile Actually Gets Used

Kitchen backsplashes remain the most common application on our jobs across Nanaimo, Parksville, and Campbell River. A subway tile backsplash handles grease and splatter the way the original hospital and kitchen installs handled worse, and the classic white version still shows up on close to half our backsplash quotes.

Shower and tub surrounds are the second most common request, particularly with a porcelain or ceramic finish that tolerates constant water exposure. Fireplace surrounds and standalone feature walls round out the list, both spaces where the tile’s clean lines do most of the visual work without competing with everything else in the room. A proper backsplash tile installation accounts for outlet cutouts, corner transitions, and substrate prep before a single tile goes up.

Location shifts the request slightly. Comox and Courtenay jobs skew toward the elongated 3×12 plank in a warm white for kitchen renovations tied to a broader remodel. Older Nanaimo character homes see more classic 3×6 white, matched to original trim and mouldings the owners want to keep intact. Campbell River’s newer builds are where herringbone feature walls come up most, usually behind a freestanding tub rather than in the shower itself.

Can Floor Tiles Be Used on Walls?

Often, yes. This is the question that comes up almost as often as the subway tile question itself, usually from someone who found a floor tile they liked and wants the same look carried up a shower wall or a feature wall. Floor tile can go on a wall, that’s the short answer. Longer version: it changes the installation in ways worth knowing before committing to it.

Weight is the first issue. Floor tile runs denser and thicker than most wall-rated tile, built to take foot traffic the wall version never has to handle. Gravity works against that extra weight the moment the tile goes vertical, which means a heavier-duty thinset, sometimes temporary support while it cures, and tighter installation tolerances to stop the tile from slumping before the adhesive sets.

Wall prep changes too. Standard drywall backs most residential walls, and it isn’t always rated for the load a large-format floor tile puts on it, especially in a bathroom where moisture adds its own stress to the equation. Cement backer board or a waterproof membrane usually needs to go up first, which adds a step and a cost that a straightforward wall-tile install skips entirely.

Kitchen Walls Versus Bathroom Walls

Floor tile on a kitchen wall, behind a range or as a backsplash, deals with grease and heat more than standing water. Slip resistance stops mattering the moment the tile is vertical, so a textured floor tile that would have been chosen for traction on the ground becomes just a texture choice on a kitchen wall, one that happens to be a little harder to wipe clean than a smooth ceramic subway tile would be. Bathroom walls carry more moisture exposure, and that’s where the backer board and waterproofing step earns its cost.

When We Say No

Large-format floor porcelain, anything over roughly 18 inches, on an older wall with unknown framing is where we start pushing back. The math on temporary support, reinforced backer board, and installation time often lands close to the cost of just choosing a wall-rated tile that gives the same look without the structural gymnastics. A wall tile installation quote usually flags this trade-off before the job gets booked, not after.

Grout Colour and the Pattern Decision

White grout with white subway tile keeps the offset pattern quiet, close to invisible from across the room. Grey or black grout on the same white tile does the opposite, pulling the pattern forward and making the layout itself part of the design rather than a background detail. Neither choice is wrong. It depends on whether the goal is a calm, unified wall or a wall that shows off the brickwork underneath.

Frequently Asked Questions

What makes a tile a subway tile?

Shape and layout more than any specific material. A rectangle with roughly a 1:2 width-to-height ratio, laid in an offset pattern, qualifies regardless of whether it’s ceramic, porcelain, or glass. The 3×6 size is traditional, not mandatory.

What are the disadvantages of subway tile?

Grout lines add up fast on a small tile, and more grout means more maintenance over the life of the wall. Standard white also shows up in enough homes that some clients worry about it reading as generic rather than distinctive. Larger-format versions and unusual colours address both concerns at a higher material cost.

Is subway tile out of style in 2026?

No, though the standard 3×6 white version has stopped being the default request it was a decade ago. Elongated 3×12 formats, colour, and herringbone layouts are where most new quotes land now. The shape itself, offset rectangles, keeps getting specified even as the size and colour choices shift.

What is a subway tile backsplash?

A kitchen or bathroom wall section, usually between the counter and upper cabinets or mirror, finished in rectangular offset tile. It’s the single most common application we see the tile used for, ahead of showers and feature walls combined.

Can I use floor tile as a backsplash?

Generally easier than putting floor tile on a full wall. A backsplash carries far less load than a shower surround, so the weight and structural concerns matter less, though slip resistance textured for foot traffic can still make a floor tile backsplash a little harder to wipe down than a smooth ceramic one.

Is there a difference between floor tile and wall tile?

Mainly density, thickness, and slip rating. Floor tile gets built to handle foot traffic and often includes texture for traction. Wall tile skips both requirements and tends to run lighter, which is why it’s the easier default for a vertical surface even when floor tile can technically be adapted.

What holds tile on the wall?

Thinset mortar does the bonding, spread with a notched trowel sized to the tile. Heavier or larger tile sometimes needs a modified, polymer-enhanced thinset and temporary support while it cures, since gravity is working against the bond until it fully sets.

What are some alternatives to wall tiles in bathrooms?

Waterproof PVC panels and acrylic surrounds cover the same moisture-prone areas with less labour and lower material cost, though neither matches tile for long-term durability or resale appeal. Large-format porcelain slabs are the other alternative clients ask about, fewer grout lines but a heavier, more specialized install.

Central Vancouver Island’s mix of older housing stock and newer builds means wall framing and drywall thickness vary a lot from one job to the next, Nanaimo through Campbell River. Confirming what’s actually behind the wall before committing to a heavier floor tile on a vertical surface saves a redo later.
