Light, mid and dark gray floors
Light gray tiles, such as Bardiglio Light marble, silver fabric looks and pale concrete looks, brighten a room almost as much as white. Mid grays, the core of most concrete and stone look porcelain, sit close to the color of everyday dust and crumbs, and together with patterned and mottled tiles they are among the most forgiving floors to live with. Dark grays and charcoals, such as Bardiglio Dark and Calypso Graphite, give a grounded, dramatic floor.
Light tones keep a small or dim room open; dark tones read best in larger rooms with good daylight, and they show pale dust and pet hair more readily than a mid tone. Many households end up in the middle of the range for exactly that reason.
Cool grays, warm grays and greige
Cool grays carry a hint of blue or green, as in Montauk Blue slate and many concrete looks, and they sit naturally with white cabinets, chrome and black fixtures. Warm grays lean toward beige or taupe. When the warmth is strong enough that the color reads as half gray and half beige, it is called greige, and greige pairs with both white and wood, brass and cream walls.
Undertones show where gray meets another neutral. A cool gray next to warm beige walls can look slightly blue; a warm gray next to stark white can look muddy. A sample laid against the room's cabinets and paint in its own light settles the question quickly.
Sizes, layouts and grout
12x24 is the most common size of gray floor tile at Stone Tile Depot, followed by 24x48 and 24x24. A 12x24 laid in a one-third offset suits most rooms; 24x48 and larger give the few-joint floor that suits concrete and stone looks; 24x24 squares read more formal. Planks from 7x48 to 9x60 carry the gray wood looks, and small hexagons and 2x2 mosaics cover bathroom floors and showers.
Grout matched to a gray tile, or one shade darker, lets the floor read as one surface and hides wear; a charcoal grout on mid-gray tile is common in kitchens and entries. A white grout does the opposite and outlines each piece, which turns the layout itself into the pattern.
Glazed and through-body gray porcelain
Most gray porcelain floor tile is glazed: a printed glaze on the face carries the concrete, stone or wood pattern, over a body that may be a different color underneath. Through-body or color-body porcelain is tinted through its thickness to match the face, so a chip on an edge shows the same gray instead of a lighter clay.
Glazed porcelain gives the widest range of looks; through-body porcelain is favored where the floor takes knocks, such as commercial entries, garages and kitchens with heavy pans. Unglazed porcelain pavers for outdoor use are typically through-body as well.
Concrete look porcelain
Concrete look porcelain reproduces the soft, uneven gray of a troweled or polished concrete floor on a porcelain body. Atelier in Olive Grey and Grey Light has a honed face, Gray Rectified comes in 12x24 with tight joints, and the Gridscale and Dimensions series add matching 2x2 mosaics and bullnose so one gray can run across floor, shower and base. Large formats such as 24x48 make the effect most convincing, since a poured floor has few joints.
Concrete looks differ in how much movement they carry. Some show only the faint clouding of a troweled slab, which reads almost solid from standing height; others carry the scattered aggregate of a ground and polished floor, or the trowel marks and small pores of a hand-finished surface. The quieter versions suit a room where furniture and walls carry the color; the busier ones hide the most and suit kitchens and family rooms.
This is the gray of modern and industrial interiors, and it suits open-plan kitchens and living areas where one floor runs through several spaces. The wider range is in concrete look tile.
Bardiglio and gray marble
Bardiglio is the classic gray marble, a blue-gray Italian stone with soft darker banding, available here in Light and Dark tones in 12x12, 18x18, 12x24, subway and herringbone mosaic. Silver Sky brings a lighter, cooler gray marble, including herringbone mosaics, and Silver Horizon a honed 1x1 hexagon.
Gray marble suits bathrooms and formal entries, and it develops a gentle patina underfoot over the years. Acidic spills dull marble's surface, and honed finishes show that least. The gray marble range is in gray marble tile.
Slate and slate look tile
Natural slate is a layered metamorphic stone whose color moves between blue-gray, green-gray and charcoal. Montauk Blue comes here in sizes from 6x24 to 24x24 and 18x36, and its textured face makes slate a traditional entry, mudroom and kitchen floor.
Slate look porcelain, such as Essence Montauk Grey in an Anti-Slip Grip face and Marlu Mist, carries the same color and texture on a porcelain body. Natural slate, including the difference between gauged and ungauged slate, is covered in slate tile, and its porcelain look in slate look tile.
Terrazzo and limestone looks
Terrazzo looks scatter small chips across a gray ground, a retro and playful floor whose speckled surface hides everyday marks well. Fashion Grey is the lighter version and Precious Black a darker one with gray chips; the Elite Fashion Grey version adds an anti-slip face for bathrooms, and Acero is a honed terrazzo tile. Limestone looks such as Lipica give a calm, even gray with almost no pattern, for rooms where the floor should stay quiet.
Gray wood look: porcelain and vinyl
Gray wood is one of the largest looks in this collection, in two materials made for different rooms. Wood look porcelain, such as Gris Argent and Peau D Elephant in 8x48 planks, is a tile: it gives the grain of weathered gray oak with the water resistance and hardness of porcelain, which suits bathrooms, kitchens, basements and rooms that open onto a patio.
Gray luxury vinyl planks, in ranges such as Laurel Reserve, XL Prescott in 9x60, Andover, Ashton and Cyrus, are a resilient floor: softer, warmer and quieter underfoot, and well suited to bedrooms, living rooms, upstairs floors and basements. Many come with matching stair nose, reducers and quarter round. The vinyl range is in gray luxury vinyl, and real gray wood in gray hardwood.
Entries, mudrooms and living areas
An entry or mudroom collects grit, water and salt from shoes, and gray is one of the colors that copes with that best. A textured face such as slate or slate look porcelain gives grip on wet days, and a mid to dark gray hides the grit between cleanings. A tile that continues from the entry into the hallway keeps the threshold clean-looking.
In living areas and open-plan rooms, large format gray tile or long gray wood look planks run continuously under sofas and dining tables, and area rugs warm the space and define zones. A single gray floor through several rooms can make a home feel more open than a change of floor at every doorway.
Gray floors in bathrooms and kitchens
In a bathroom, gray pairs with white walls and fixtures in a few familiar ways: a gray floor under white subway walls, a white floor with a gray accent wall, or gray and white mixed in one pattern, such as a Bardiglio basketweave. Small hexagons such as Gris Fonce, Hexley Graphite and Silver Horizon give a classic bathroom floor, and anti-slip porcelain in gray suits a shower area.
In a kitchen, a mid-gray concrete or stone look in 12x24 or 24x24 is a common choice for one continuous floor through an open-plan kitchen and dining area. White and light cabinets over gray give a soft, tonal room; navy, green or black cabinets stand out against light gray; wood cabinets warm up a cool gray. A countertop with gray veining ties the floor to white cabinets, and keeping the grays in a room to one undertone makes the whole scheme look deliberate.
Pavers and copings outdoors
Gray continues outside in pavers and pool copings: Warm Gray porcelain pavers in 24x24, Paris tumbled limestone pavers, Tahoe tumbled marble in a French pattern, Silver Sky marble in a Versailles pattern and Wynwood brushed marble. A mid-gray paver avoids both the heat of a very dark surface and the glare of a white one, which makes it a balanced choice around a pool. The outdoor range is in pavers.
Trim and transitions
Gray floors include a large set of trim pieces, most of them made for the vinyl planks: stair nose, reducers, T moldings and quarter round in matching colors, which finish stairs and doorways where the floor meets another surface. Porcelain series such as Gridscale add bullnose pieces that turn the floor tile up the wall as a base. Where tile meets wood or carpet at a doorway, a metal or stone threshold handles the change in height.
