Porcelain vs. ceramic tile: Is this an issue between two vastly different types of materials or is it simply a war of words?

For consumers, the terms porcelain and ceramic are often used interchangeably as if they were the same thing. And this is understandable since ceramic and porcelain tiles are used for the same applications, are installed the same way, and have largely the same merits and drawbacks as a flooring or wall surface material.

At the same time, tile stores may claim a world of difference between the two, probably to justify porcelain's reputation, cachet, and its higher prices. Is there really a difference between porcelain and ceramic tile?

Porcelain and ceramic tile are both are part of the larger category of tiles that can generally be called ceramics—a category that includes all rigid tiles shaped from natural earthen clays and hardened by heat. In the modern tile industry, however, porcelain tiles occupy their own category, assigned there because they meet certain specifications.

Porcelain vs. Ceramic Tile: Major Differences

According to the Tile Council of North America, the industry group that decides whether a tile is porcelain or ceramic, everything boils down to whether the tile can meet a set of highly controlled water absorption criteria. Both ceramic tile and porcelain tile usually receive a surface glazing that makes them hard to distinguish from one another.

Porcelain Tile

Porcelain tile has a water absorption rate of 0.5 percent or lower as defined by the American Society for Testing and Materials (ASTM) section C373. To test this, the fired tile is first weighed, then it is boiled for five hours and left to sit in water for 24 hours. Then it is weighed again. If the tile weighs less than half of one-percent more as a result of water-absorbing into its surface, it is considered impervious porcelain.

To achieve this density, a special kaolin clay mixture is used, which is finer and purer than most ceramic clay. It usually contains notable levels of quartz and feldspar mixed in. Porcelain tiles are fired at temperatures ranging from 2,200 to 2,500 degrees Fahrenheit. To the consumer, it generally suffices to say that porcelain is a dense, fine-grained, smooth tile that is impervious to water than ordinary ceramic tile.

Porcelain tile typically receives a surface glazing treatment—a coating of liquified glass material—while some forms of ceramic tile are left unglazed. As a rule porcelain tile is more impervious than ceramic tile and is thus subject to less water infiltration.

Ceramic Tile

Tile defined as ceramic uses a coarser clay with a smaller ratio of fine kaolin clay, and it generally lacks some of the additives used in porcelain clay. Ceramic tile is fired at lower temperatures, generally about 1,800 to 2,000 degrees Fahrenheit. Ceramic tile can be slightly more prone to water infiltration than is porcelain tile, though these differences are fairly minimal if the ceramic tile is glazed.

Ceramic tile and porcelain both are often manufactured with a glazed surface coating, and at a glance, they may be indistinguishable.

Porcelain Tile

One recent innovation with porcelain tile is the ability to manufacture them to resemble different materials. Porcelain tiles are available that are remarkably good at mimicking natural stone such as marble or even wood grains. This makes porcelain tile an excellent choice where you want the look of wood without wood's susceptibility to water damage.

Ceramic Tile

Most ceramic tile that is not categorized as porcelain is a solid color, but simulations of wood grains or natural stone can still be found in ceramic tile.

Best for Appearance: Porcelain Tile

Porcelain tile has the edge when it comes to appearance, for the simple reason that it is available in more colors, patterns, and surface finishes.

Water and Heat Resistance

Both ceramic and porcelain have very good resistance to heat and are sometimes used on countertops.

Porcelain Tile

Porcelain tile is denser, heavier, and more impervious to water, and thus is a better choice than ceramic tile for outdoor locations, although outdoor use is recommended only in mild climates. Porcelain tile has excellent resistance to heat, making it a good choice for countertop surfaces.

Ceramic Tile

Ceramic tile is somewhat more susceptible to moisture infiltration, though the differences are minimal if the tile is glazed. As long as the face of the ceramic tile is glazed and in good condition, the face will resist water.

Unglazed portions of the back or side of the tile will not resist water. Embedded in thinset mortar, the bottom of ceramic tile usually will not have contact with water. Similarly, the sides of the tile, filled in with grout, should not experience water intrusion.

Ceramic tile has excellent heat resistance, making it a good choice for countertops.

Best for Water and Heat Resistance: Porcelain Tile

Porcelain has slightly better water resistance, making it possible to use it in outdoor locations in regions with mild climates. Ceramic tile is generally not recommended for outdoor locations in any environment.

Care and Cleaning

Porcelain Tile

Porcelain tile is easy to clean up by damp-mopping with a mild water-soap solution. The cementitious grout filling the joints between tiles needs to be periodically sealed to guard against stains and mildew.

Ceramic Tile

Ceramic tile has the same care and cleaning needs as ceramic tile—routine damp-mopping and period sealing of grout joints.

Durability and Maintenance

Porcelain Tile

Porcelain clays are denser and thus less porous than ceramic clays. This makes porcelain tile harder and more impervious to moisture than ceramic tile. Due to its through-body composition, it is considered more durable and better suited for heavy usage than ceramic tile. Chip a porcelain tile, and the color continues all the way through; as a result, the damage is nearly invisible. Porcelain is an easy material to maintain, requiring only period sealing of the grout lines.

Ceramic Tile

Chip a ceramic tile and you find a different color underneath the top glaze, which means that chips are likely to be quite visible. The clays used for ceramic tile are less dense than porcelain clays, which means ceramic tiles are somewhat more prone to cracking and breaking. Unglazed ceramic tiles may also need to have sealers applied to the entire tile, not just the grout lines.

Best for Durability and Maintenance: Porcelain Tile

As a harder material that has solid color throughout, porcelain tiles are stronger and more durable, and chips are less likely to be visible.


Both forms of tile flooring are installed using similar methods. Tiles are adhered to an underlayment of cement board using a mortar-based thin-set adhesive. Once the tiles are set, the joints between tiles are filled with mortar-based grout, which is sealed against moisture once it dries. There are slight differences in how ceramic tile and porcelain tile are handled, based on their differing densities.

Porcelain Tile

Porcelain tile is slightly more brittle and may require the experienced hand of a professional tile-setter to cut properly. A wet tile saw is the recommended tool for cutting porcelain, while an inexpensive snap cutter generally works fine with ceramic tile.

Ceramic Tile

While ceramic tile is less dense than porcelain tile and thus less durable, it is also a far easier material for do-it-yourselfer homeowners to cut manually, by wet tile saw, or with a snap tile cutter.

Best for Installation: Ceramic Tile

Although techniques are very similar, ceramic tile is slightly easier to install, since it is a softer material that is easier to cut. Generally, homeowners installing their own tile will find little difference between ceramic and porcelain tile in terms of ease of installation.


Porcelain Tile

Porcelain is more expensive to manufacture than ceramic tile, resulting in higher retail prices. Porcelain tiles begin at about $3 per square foot, running to $35 per square foot.

Ceramic Tile

With all other factors equal, ceramic tile is cheaper than porcelain tile. Ceramic tile tends to run about 60- to 70-percent of the cost of porcelain tile, on average. Ceramics can be purchased for as little as $.50 per square foot or as much as $35 per square foot. There are ways to pay less for tile online, too.

Best for Cost: Ceramic Tile

As a general category, ceramic tile is less expensive than most porcelain tiles. But there is a surprisingly large range of prices for both types of tiles. Note that the very highest quality designer tiles tend to cost roughly the same for ceramic and porcelain.


Both ceramic and porcelain tiles are very durable building materials, provided they are well cared for. Homeowners will find little appreciable difference between porcelain and ceramic tile in terms of lifespan.

Porcelain Tile

Porcelain tile is a harder substance and wears better than ceramic tile, but its hardness can also make it more susceptible to cracking under structural shifting in a building.

Ceramic Tile

By some estimates, a ceramic tile floor can last from 75 to 100 years if the grout is maintained properly and sealed regularly. While it theoretically is softer and doesn't wear as long as porcelain tile, it also tends to resist cracking due to structure shifting somewhat better than does porcelain tile

Best for Lifespan: Tied

Both materials can be lifetime surfaces if they are properly maintained.

The Verdict

There is not a clear winner when it comes to choosing ceramic tile or porcelain tile. Both are similar building materials, and most forms are equally suitable as flooring material, wall covering, or countertop surface.

While you should make sure that the tile is rated for the use (tiles rated for floor use are typically thicker and the product will specify that this is an allowed use), your choice of ceramic or porcelain tile really boils down to what particular tile style appeals to you visually.

Porcelain is sometimes preferred for its durability and style versatility, but as every situation and use is different, picking between porcelain and ceramic tile will come down to the space itself.

Top Ceramic and Porcelain Tile Brands

Most companies that manufacture ceramic tiles also offer a good selection of porcelain tiles. Some popular brands include:

  • Marrazzi: This Italian company has a broad distribution in the U.S., and its products are even available at big-box home improvement centers.
  • Daltile: Owned by flooring giant Mohawk, Daltile is an upper-end manufacturer that sells both ceramic and porcelain tiles at specialty tile stores and at its own showrooms.
  • AmericanTile: This company offers one of the broadest selections of ceramic and porcelain tiles available, ranging from tiny mosaic sheets to expansive floor tiles. There are many affordable options available.
  • American Olean: Offering many lines of ceramic and porcelain tile, American Olean sells mainly through specialty tile and flooring shops, as well as through contractor sales.

In addition, many of the giant flooring corporations, such as Shaw and Armstrong, offer porcelain and ceramic tiles.


Things to Consider When Choosing Porcelain or Ceramic

How Porcelain Is Certified

For years, tile manufacturers and tile distributors did not see eye to eye on the issue of how to define porcelain vs. ceramic tile. By 2008, the debate had reached such a fevered pitch that the manufacturers, represented by the Tile Council of North America (TCNA), and the distributors, represented by the Ceramic Tile Distributors Association (CTDA), formed a third-party organization to settle the differences and come up with a standard definition for porcelain tile. They called this new group the Porcelain Tile Certification Agency (PTCA).

According to the PTCA, it is not simply enough for a tile to be impervious (a tile term, meaning that it is good against water). The tile has to meet those ASTM C373 standards of water absorption by sending in five tile samples for testing, paying a fee, submitting a participation agreement, and renewing certification every three years. After certification, a company may use the PTCA Certification Mark branding. At last count, 28 North American tile companies had received certification as producing authentic porcelain tile.

The PTCA's fight did not end with the establishment of water absorption criteria. Today, about 70 percent of the tile purchased in North America is imported. The PTCA indicates that much of the imported tile that is prominently labeled as being "porcelain" is not porcelain.

In one independent blind test conducted by the TCNA, 1,466 tiles were tested for the water absorption criteria that would qualify those tiles for porcelain status. The conclusion was startling. Close to 23 percent (336 total) of the tiles tested that were labeled as "porcelain" were falsely labeled. In other words, they absorbed water over that 0.5 percent benchmark. In some cases, the so-called porcelain tile had an alarming 3 percent absorption rate.

This is an ongoing issue for the PTCA, especially since more tiles are being imported. As a self-policing, self-funded organization, the PTCA lacks the resources to test every single tile that crosses the international border for water absorption criteria.

One way to determine if a porcelain tile is truly porcelain is to check the box for the PTCA Certification Mark. Currently, this is the distinctive green and gray logo that reads "Certified Porcelain Tile 0.5% water absorption," with a diamond-shaped tile forming the "O" of "porcelain."

However, the PTCA mark is subject to change. Plus, dishonest tile companies may fraudulently mislabel their boxes. That being the case, the only way to know for certain if that tile is truly porcelain is to check it against the PTCA's database of tile makers and their series of porcelain tiles. 

The PTCA's sole interest is in assuring that tiles that are labeled as porcelain meet or exceed water absorption rate standards. But it can also be helpful to look at standards defined by American National Standards Institute (ANSI) A137.1, which says in part that porcelain tile can be defined as tile that is produced with a "dust-pressed method of a composition resulting in a tile that is dense, impervious, fine-grained, and smooth with a sharply formed face." It is important to note that ANSI A137.1 also references those important ASTM C373 standards of water absorption rates.

  • Is porcelain or ceramic tile better for bathrooms?

    In general, porcelain tile is better for bathroom flooring. That's because it is more resistant to water than ceramic. But a glazed ceramic should do fairly well in a powder room where the flooring isn't exposed to much water if you want to save some money.

  • Do porcelain tiles chip easily?

    As long as they're installed properly, porcelain tiles are dense and not prone to chipping. But due to their density, they don't flex well if the building shifts and thus are prone to cracking if a shift occurs.

  • Which is better for kitchen floors: ceramic or porcelain?

    Because porcelain tile is harder and more durable than ceramic, it's recommended for high-traffic areas, such as the kitchen. It's also easy to clean and maintain.
