Porcelain and ceramic are both popular tile materials, and the choice between them comes down to one key difference: water absorption. Here is what to know before you decide.
Porcelain is a denser, less porous tile. It is fired at a higher temperature with finer clay than ceramic, giving it a water absorption rate of less than 0.5%. This makes it the stronger choice for showers, outdoor spaces, and high-traffic floors.
Ceramic is typically the more budget-conscious option. It is durable and well-suited to walls, backsplashes, and lower-traffic interior spaces, with a wide range of design options at a more accessible price point.
Neither is objectively better. The right choice depends on where the tile is going and how much moisture or traffic the space sees. The sections below walk through each scenario.
Tile flooring can be made from several different materials. Two of the most popular are porcelain and other ceramics, such as terracotta. Neither product is objectively “better” than the other; it simply depends on what you’re looking for. For example, porcelain tile offers slightly more durability, while ceramic tile is typically the more budget-conscious option. Both are highly customizable, with a variety of patterns, textures, and colours to mix and match. You can also choose between a sleek glazed finish or an earthy unglazed finish, setting the perfect tone for any indoor or outdoor space.
Although porcelain is technically a type of ceramic, the manufacturing process is what sets it apart. Porcelain is made from a more refined, finer-grain clay and fired at a significantly higher temperature than standard ceramic. This produces a denser tile body with far fewer microscopic pores.
That density difference shows up in one key specification: water absorption. Porcelain tile has a water absorption rate of less than 0.5%, while ceramic tile absorbs noticeably more water. This single difference is the reason porcelain performs better in wet areas, outdoor applications, and high-traffic floors, while ceramic remains a strong, more affordable choice for walls, backsplashes, and lower-moisture interior spaces.
Both materials share the same design flexibility: glazed or unglazed finishes, a wide range of colours and patterns, and suitability for floors or walls, depending on the specific product. The manufacturing difference is what drives the practical recommendations in the sections below.

Porcelain's denser composition makes it the harder and more durable of the two materials. It resists scratches, chips, and surface wear better than ceramic, which is part of why it is the standard recommendation for high-traffic floors and commercial spaces.
That same density has a practical trade-off during installation: porcelain is harder to cut than ceramic. Ceramic's softer body makes it easier to score and snap with standard tools, while porcelain typically requires a wet saw with a diamond blade for clean cuts. This is one of the reasons professional installation is recommended for porcelain, particularly for complex layouts, cuts around fixtures, or large-format tiles.
Water absorption also plays a role in long-term durability, especially outdoors. Porcelain's low absorption rate means it holds up well to freeze-thaw cycles. Ceramic, with its higher absorption rate, can take on small amounts of moisture that expand when frozen, which over time can lead to cracking in exterior applications. This is why porcelain is generally the only recommended option for outdoor tile in climates with freezing winters.
In terms of lifespan, both materials can last for decades with proper installation and care. Porcelain's added density gives it an edge in high-traffic or high-moisture conditions, while ceramic performs just as well in the lower-traffic, lower-moisture spaces for which it is best suited.
Porcelain is the recommended choice for shower floors and walls. Its water absorption rate of less than 0.5% means it will not take on moisture over time, which is critical in an environment with constant water exposure. Ceramic can be used in showers, but porcelain's lower absorption rate makes it the safer long-term choice for this application.
Porcelain is generally preferred for floors, especially in high-traffic areas like kitchens, entryways, and hallways. Its added hardness and density mean it holds up better to foot traffic, dropped items, and daily wear. Ceramic floor tile can work well in lower-traffic rooms, but for spaces that see heavy use, porcelain's durability advantage makes it the stronger pick.
Ceramic is well-suited to walls and backsplashes. Since these surfaces see far less moisture and physical wear than floors, ceramic's higher absorption rate is not a practical concern, and its lower cost and wide range of design options make it a popular choice for this application. Porcelain can also be used on walls, but ceramic is often the more cost-effective option where durability requirements are lower.
Porcelain is the only recommended option for outdoor applications, particularly in climates with freezing winters. Its low water absorption rate prevents the freeze-thaw damage that can crack ceramic tile over time. If you are tiling a patio, outdoor kitchen, or any exterior surface, porcelain is the material to choose.
Both ceramic and porcelain tile are available in glazed and unglazed finishes, and this choice is independent of which material you select.
Glazed tile has a liquid coating applied and fired onto the surface, creating a protective layer that is resistant to stains, scratches, and moisture. Glazing also opens up a much broader range of colours, patterns, and finishes, from matte to high-gloss. For most indoor floor applications, glazed tile is the standard choice because the glaze adds a layer of protection on top of the tile body's natural properties.
Unglazed tile has no surface coating, giving it a more natural, earthy appearance that shows the tile's true material colour and texture throughout. Unglazed tile tends to have a more matte, textured surface, which can provide better slip resistance in some applications. Because it lacks the protective glaze layer, unglazed tile for floors typically requires sealing to resist stains and moisture, especially with porous ceramic.
Whether you choose porcelain or ceramic, glazed or unglazed, comes down to the look you want and the level of protection your space requires.

If you are trying to identify a tile you already have, or want to confirm what you are buying, there are three reliable ways to tell ceramic and porcelain apart.
For new tile purchases, check the packaging for ASTM certification, which indicates the water absorption classification and confirms whether a tile is porcelain or ceramic.
For showers, outdoor spaces, and high-traffic floors, porcelain is the better choice because of its low water absorption and added durability. For walls, backsplashes, and lower-traffic interior spaces on a tighter budget, ceramic is a strong, cost-effective option. If you are unsure which applies to your project, our flooring experts can help you match the right material to your space.
In high-moisture or high-traffic conditions, porcelain typically lasts longer due to its lower water absorption rate and greater hardness. In lower-traffic, lower-moisture spaces like walls and backsplashes, ceramic performs just as well and can last for decades with proper care. The deciding factor is less about the material's overall lifespan and more about matching the material to the demands of the space it is installed in.
There are three ways to tell: check the colour through the tile body on a chipped or broken piece (porcelain is consistent throughout, ceramic often shows a different colour underneath the glaze), feel the unglazed back of the tile (porcelain is smoother and finer-grained, ceramic is coarser), and compare the weight (porcelain is denser and heavier for the same size). New tile packaging will also show ASTM certification, indicating the water absorption classification.
