Outdoor Tile for Patios, Pool Decks and Gardens

Outdoor patio tile sets the character of a garden long before anything is planted. Sun-baked Mexican terra cotta, glazed color from Mexico and Morocco, dense Japanese ceramic, pressed cement pattern, volcanic stone and quarried limestone can all live outdoors, but not all of them can live everywhere. Climate decides the shortlist; taste decides the rest. Zia's outdoor collection is arranged with both in mind, from a Los Angeles courtyard to a farmhouse patio in Vermont.

Outdoor Tile Requirements

Whether a tile belongs outside comes down to three things: the clay or stone, how it was fired or formed, and its surface. Each affects how much water the tile takes in, and water is the issue.

In cold climates, moisture inside a tile expands as it freezes, again and again through the winter. Only materials made for that cycle should go outdoors there. At Zia, those are unglazed Cotto, Belgian Bluestone and our ceramics.

Where winters stay above freezing, the field opens up. Glazed Cotto Allende and zellige, cement tile, Cantera stone, and French and Moroccan limestone all join the list.

Outdoor Patio Tile at Zia

Zia's outdoor range moves between clay and stone, and each material brings its own temperament to the garden: clay that deepens with age, glaze that catches sun and water, pattern pressed into the body of the tile, volcanic texture, quarried calm.

Cotto

Cotto is terra cotta made by hand near San Miguel de Allende, Mexico, from local clay pressed into molds and high-fired. Left unglazed, it is suited to outdoor floors in any climate, freeze-thaw regions included, and the clay surface softens into the life of a patio.

There are six colorways: the classic Adobe, Fired Earth and Red Clay, and the less expected Blanco, Madera and matte-black Oscura. Time and footsteps deepen each tone, so an installation starts out one way and slowly becomes another. That is the point of it.

Cotto is made for outdoor floors, not for pools or spas.

Cotto Allende

Cotto Allende is Cotto's glazed sibling: the same high-fired clay, glazed by hand in twenty colorways named for Mexican places and plants. It comes in four shapes, a 4x4 square, a 4x8 rectangle, a triangle and a 1.5x8 mini bar, and its finishes run from matte to glossy, with speckling that varies by colorway.

Outdoors, Cotto Allende carries glazed color onto patios and pool decks where winters stay mild, and because it is high-fired, it can line the pool itself, below the waterline as well as above. It is not suited to freeze-thaw climates.

Zellige

Zellige is Moroccan tile made by hand in a tradition some eight hundred years old, shaped from clay and glazed by hand. Its glazes shift in color and sheen as the light moves, which outdoors means all day long.

In mild climates, colorways from the outdoor collection such as Pure White and Tidepool bring that glaze to courtyard walls, sheltered corners and the waterline band of a pool. Zellige is not suited to freeze-thaw climates.

Ceramics

Zia's ceramics are designed in Los Angeles and made in Japan, dry-pressed and fired to a density close to porcelain. In Japan, tile made to this standard clads the facades of buildings; here it brings the same composure to a garden wall or a pool.

They are the most precise of the outdoor lines, all clean lines and restraint, in matte, satin and glossy finishes. Outdoors they suit exterior walls in any climate, and they are made for pools: at the waterline and below it.

Cement Tile

Zia's cement tile is made in Vietnam by a method French and Catalan craftsmen established in the 1850s. Mineral pigment and cement are poured into a steel mold, pressed and cured, with no kiln involved. Because the pigment runs through the body of the tile, the pattern is part of the material, not printed on top.

The finish is matte, in a wide range of colors and patterns, including Pomelo Terracotta from the outdoor collection. Its soft face sits easily in full sun, and beside rough garden stone the pressed pattern reads as a crisp graphic counterpoint. Cement tile belongs outdoors only in non-freeze-thaw climates.

Cantera Stone

Cantera is volcanic stone, cut by hand and prized in Mesoamerican architecture for millennia. Its visible aggregate and mineral inclusions mark every piece as stone, in earthy tones that settle naturally among planting.

The Sierra 12x24, featured in the outdoor collection, covers a terrace at a calm, even scale. In low afternoon sun the aggregate holds small shadows across each face, and the whole surface takes on a fine mineral texture as the light goes. Cantera suits exteriors in non-freeze-thaw climates. Its porosity rules out pools and spas.

Limestone

Zia's limestone comes from three places: honed classics from near Fez, Morocco; French limestone from near Bordeaux; and Belgian Bluestone from southern Belgium. Finishes range from honed, smooth and naturally matte, to bush-hammered, whose textured face breaks the light into a fine grain of shadow.

Outdoors, every limestone gathers a patina underfoot, and Belgian Bluestone pales gradually to a softer grey in the sun. Belgian Bluestone is suited to exteriors in any climate. French and Moroccan limestone belong outdoors only where winters stay mild.

Patios

On an open patio, Cotto sets a generous scale. The 13x13 square and Big Alcazar, an arrowhead whose tiles lock into a geometric star, both carry across the length of a garden, and their joints set a slow, even rhythm. The 8x9 hexagon, featured in the outdoor collection in Adobe, works at a middle scale.

Where frost never arrives, the options multiply: pressed pattern in cement tile, quarried stone in limestone, glazed color in Cotto Allende.

Pool Decks and Pools

Pool tile is really two decisions: the surface inside the water and the deck that frames it. Below the waterline, there are three choices. Cotto Allende brings high-fired clay under hand-applied glaze, in colors that turn the water itself into part of the palette. Zia's ceramics bring precision, their near-porcelain density entirely at home underwater. And Glass Mosaics, made from 98% recycled glass, are the pool tile in its purest form: non-porous, needing no sealer, and laid in saturated fields of color that the water only deepens. At the waterline, glazed zellige frames the edge with a band of shifting light. Cotto and Cantera stay out of the water entirely. For anything else, talk to the Zia team.

The deck is an outdoor floor, so the climate rules apply. In mild climates, Cotto, Cotto Allende and Zia's limestones can all run to the water's edge: warm clay, glazed color or quarried stone. In freeze-thaw climates, unglazed Cotto and Belgian Bluestone are the choices.

Wet floors come with specifications of their own, from slip resistance to grout joints and surface treatments. Each material's installation guide sets these out; review them with your designer and installer, particularly on commercial projects.

Garden Paths and Courtyards

In garden tile, pattern earns its place at a smaller scale. Stars & Cross, a 6x6 eight-pointed star paired with a cross, follows a Moorish pattern found in courtyards from Granada to Puebla. The 6x6 Alcazar interlocks curved and straight edges at the same compact size. Both are unglazed Cotto, so a Spanish-style courtyard in either can be laid in any climate.

For broader terraces in mild climates, Cantera's Sierra covers the ground evenly, and its aggregate reads unmistakably as stone among the greenery. Limestone suits the same settings, along paths and low garden steps: Belgian Bluestone anywhere, French and Moroccan limestone where winters stay mild.

Sealing varies by material, and outdoors it differs from indoors. Zia's installation guides cover preparation, setting and sealer selection for each. Wear a dust mask and eye protection when working with thin-set, sealants and grout, and see Zia's Proposition 65 warnings for full guidance.

How Climate Narrows the Field

In frost country, the choice comes into focus quickly: unglazed Cotto and Belgian Bluestone on the ground, ceramics on the walls. Cotto alone offers six colorways in shapes from 4x4 squares to the 13x13 Big Alcazar, enough to finish an entire garden, patio, paths and pool deck, in warm clay.

In a mild climate, every line is in play, and the question moves from climate to surface. Glazed color comes from Cotto Allende or zellige, graphic pattern from cement tile, and quarried stone from Cantera or limestone.

The Outdoor Collection at Zia

Settle the frost question first, and the whole outdoor collection becomes a short, workable list before color or pattern enters the conversation. After that, it comes down to how a material looks against sun, water and planting: glazed color beside a pool, perhaps, or quarried stone along a garden path.

Frequently Asked Questions About Outdoor Patio Tile

Which tile can be installed outdoors in a freeze-thaw climate?

At Zia, unglazed Cotto and Belgian Bluestone are suited to outdoor floors in freeze-thaw climates, and ceramics to exterior walls. Cotto Allende, zellige, cement tile, Cantera, and French and Moroccan limestone belong outdoors only where winters stay above freezing.

Do outdoor tiles need to be sealed?

Most do, and outdoor sealing differs from indoor: the protective wax used inside can discolor in UV light, so exterior installations take a penetrating sealer instead. Each material's installation guide sets out the steps. For any material or installation question, contact the Zia team at info@ziatile.com or 310-844-1170.

How much outdoor tile should a project order?

Plan for at least 15% beyond the measured area, for cuts and for curating the color range during layout. For specialty shapes or a more controlled layout, plan for up to 25%, which gives the installer room to balance handmade variation across a patio, path or pool deck.

What color options are available for outdoor patio tile?

Color follows material. Cotto comes in six colorways, from classic earth tones to matte-black Oscura. Cotto Allende offers twenty, named for Mexican places and plants, from matte to glossy. Zellige brings glazed colorways such as Pure White and Tidepool, and cement tile brings pattern, such as Cairo White Black. Ceramics add crisper color in matte, satin and glossy finishes. Cantera and limestone keep to earthy, quarried tones that sit easily with planting.
