What Is Zellige Tile and Why Do Designers Love It?

Zellige is a handmade Moroccan terracotta tile, formed and glazed by hand so that no two pieces come out exactly alike. The glossy glaze sits on a slightly wavy, uneven surface, which catches light in a way flat, machine-made tile cannot. That hand-crafted variation, the soft color shifts, the small surface pits, the way light moves across a wall through the day, is the whole reason designers keep specifying it.

At Bedrosians, we carry Zagora, our collection of genuine handmade Moroccan zellige, in 10 earthen colorways at the affordable-luxury tier. We have been a family-owned tile and stone company for 78 years, with 44 showrooms across 11 states where you can see how zellige's color and light play read in person before you order a full project's worth.

What is zellige tile?

Zellige (also spelled zellij or zillij) is glazed terracotta tile made by hand in Morocco, traditionally in and around the city of Fez. Each tile is pressed from natural clay, dried, fired, dipped in a mineral glaze, fired again, and then cut and shaped by hand. The result is a tile with a glossy, slightly uneven face and naturally irregular edges. Those irregularities are the point.

Slight differences in thickness, hand-cut beveled edges, surface pitting, fine hairline cracks in the glaze, and color shifts from tile to tile are all normal markers of the real thing. None of it is a flaw. It is how you tell authentic zellige from a rectified ceramic that looks identical from one tile to the next.

The name traces back to Arabic. One widely cited explanation links it to "al-zulayj," meaning "little polished stone," a reference to the marble and stone mosaics that early Moroccan potters set out to imitate using abundant local clay instead of costly imported marble. That same root carried into the Spanish and Portuguese word "azulejo," the painted glazed tile of Iberian architecture. You can read more on the history of zellij and how it spread.

Where zellige tile comes from

The craft goes back roughly a thousand years. The earliest forms appear in North Africa around the 10th century, and the technique reached Morocco by the 12th. It hit its artistic peak between the 13th and 15th centuries under the Marinid dynasty, when Fez became the center of production and zellige covered the walls, fountains, and courtyards of madrasas, palaces, and mausoleums.

Much of that early work was built on Islamic geometric design, with interlocking star and polygon patterns assembled from thousands of hand-cut pieces. Fez is still the global home of traditional zellige, and the methods used to make it have barely changed in centuries.

How zellige tile is made

Almost every step happens by hand, and each one adds to the variation you see in the finished tile.

• Clay sourcing and refining. Natural gray clay is dug from deposits around Fez, soaked in water for several days, then filtered and kneaded by hand to remove stones and air pockets.

• Molding and drying. The clay is hand-pressed into wooden molds, leveled with a spatula, and laid out to dry in the sun.

• First firing. The dried tiles get a bisque firing that hardens the clay while keeping it porous enough to absorb glaze.

• Glazing and second firing. Each tile is hand-dipped in a glaze made from ground minerals and metal oxides. Cobalt produces deep blue, copper produces green, iron produces warm yellow, and manganese produces brown and purple. The glazed tiles are fired again in wood-fueled beehive kilns.

• Cutting and shaping. After firing, a craftsman draws the pattern onto the glazed face by hand, and a cutter shapes each tile with a sharp, adze-like hammer called a menqach. The undersides of the edges are beveled so the tiles can sit tight against one another.

• Mosaic assembly. For mosaic patterns, the cut pieces are arranged face-down from memory, then backed with a binding layer and lifted upright to reveal the finished design.

Wood-fired beehive kilns heat unevenly, so tiles closer to the flame take on different glaze thickness, tone, and crazing than tiles further away. The maker is not chasing perfect consistency. The variation is built into the material.

Why designers love zellige tile

The appeal comes straight from the handmade process. Because every tile is glazed and cut by hand, zellige does things a machine-made tile cannot. Texture is something designers keep gravitating toward in tile, and zellige delivers it with no pattern and no print, a quality design coverage of tactile tile keeps returning to.

Light play across the surface

A standard machine-made tile has a perfectly flat face, so it reflects light on a single plane. Zellige's surface is gently wavy, and the glaze pools at different thicknesses across each tile. When light hits it, it refracts at slightly different angles, producing a shimmering, almost watercolor finish. The same wall reads as a bright gloss in the morning and a soft satin by evening.

Color depth and lived-in character

Because no two tiles fire exactly alike, a finished zellige wall holds subtle shifts in tone from piece to piece, and designers use that range on purpose. The minor glaze skips, the small pits, the faint hairline cracks, and the soft edge variation read as depth and character. It gives a brand-new installation the kind of presence that usually takes years to develop.

Shadow and movement at the joints

Installed with tight joints, the slight differences in tile size and thickness create small physical offsets, called lippage. On a wall, those offsets catch light and cast fine shadows along the edges, breaking up what would otherwise be a flat surface. Over time the glaze develops a soft patina, which is part of why zellige sits comfortably in both modern and traditional rooms.

Where to use zellige tile

Zellige is at its best on vertical, lower-impact surfaces where the texture and light play can be seen up close. The strongest applications include:

• Kitchen backsplashes

• Bathroom and shower walls

• Fireplace surrounds

• Interior feature and accent walls

In a bathroom or shower, zellige works well as long as the substrate behind it is properly waterproofed. The clay body is naturally porous and the glaze is not fully waterproof, so moisture can move through grout joints if the waterproofing underneath is not done correctly.

Can you use zellige tile on floors?

In most cases, no. Zellige is generally not recommended for high-traffic floors. The hand-cut edges and glazed surface can be slippery when wet, and the glaze is more prone to scratching and chipping under foot traffic than a floor-rated porcelain. If you do use it on a floor, keep it to light-use residential spaces, and seal and maintain the surface carefully. It is also not suited to chemically treated pools or to freeze-prone outdoor settings, where water in the porous body can crack the tile.

How much does zellige tile cost?

The prices in this section are general market estimates. Actual costs vary by region, colorway, project size, and site conditions. Use these ranges as a planning guide, then get a quote for numbers specific to your project.

Zellige sits at the premium end of the tile market, and the cost is driven by labor. Every tile is handled many times by skilled artisans during molding, glazing, firing, and cutting, and a share of them break during firing and shipping. That craft is the value, and it is why a zellige wall reads as elevated rather than ordinary.

Installation adds to the total because zellige needs setters who are comfortable with irregular, non-rectified tile, which tends to push the labor toward the higher end of the range. For context, tile installation labor runs roughly $5 to $14 per square foot for floors and $20 to $35 per square foot for backsplashes and countertops, and some installers bill by the hour at about $60 to $120, according to tile installation cost data from Bob Vila.

One more factor is overage. Because the tile varies and some pieces get curated out or trimmed, plan to order extra:

Ordering enough at once also keeps your tile within the same general color range, since a later reorder may fire differently.

How to care for and seal zellige tile

Zellige holds up well when it is installed and maintained correctly. A few points matter more than the rest, and our full installation, care, and maintenance guidance covers the details.

• Sealing. Fully glazed zellige field tile on a dry wall generally does not need sealing. In showers, backsplashes, and other wet areas, seal both the tile and the grout after the grout cures, then reapply every one to two years. Unglazed natural terracotta is porous and should always be sealed.

• Grout. Use an unsanded grout. Sanded grout can scratch the glaze during application.

• Cleaning. Clean with warm water or a pH-neutral tile and stone cleaner. Avoid acidic cleaners like vinegar and lemon, and avoid bleach or ammonia, since these etch and dull the glaze over time. Skip steel wool and abrasive pads.

A good installer will also soak the tiles briefly and blend them across multiple boxes before setting, which spreads the natural color variation evenly across the wall instead of grouping it in one spot.

Sample zellige before you order

Because zellige varies from piece to piece, it is hard to judge from a screen. Color, gloss, and the way the surface catches light all read differently in person and in your own space. With a handmade tile, sampling first is simply the right move.

You can order $1 samples on bedrosians.com, or get 5 free with code SHIPFREE5 on a first order, and see how a colorway looks in your actual lighting before you commit. Our Zagora zellige comes in field tiles (4×4 and 2×6) and mosaics (2×2 and a triangle shape), across 10 earthen colorways, so it helps to handle a few formats and tones side by side. Our guide to sampling tile is worth a read before a project like this. You can also visit one of our showrooms to see full zellige walls in person, which is the best way to read the variation and light play before you buy.

Frequently asked questions about zellige tile

Is zellige tile waterproof?

Not completely. The terracotta body is porous and the glaze is not fully waterproof, so zellige relies on proper substrate waterproofing in wet areas. The tile itself handles moisture well when the installation behind it is done correctly.

Can you use zellige tile in a shower?

Yes. Zellige works on shower walls as long as the substrate is properly waterproofed and the tile and grout are sealed. It suits shower surrounds and bathroom walls well, though not shower floors with heavy standing water.

Does zellige tile need to be sealed?

Glazed zellige field tile on a dry wall usually does not. Unglazed terracotta always needs sealing, and in wet areas it is best to seal both the tile and grout after grouting, then reseal every one to two years.

How much zellige tile should I order?

Order about 15% overage for standard square layouts, and 20% to 30% for complex patterns or when you plan to curate the color range. This covers cutting, the occasional shipping breakage, and natural variation.
