Ceramic Tile vs. Porcelain Tile. What’s the difference?

This question comes up often…What is the difference between ceramic and porcelain tile?


ceramic vs porcelain tileTile terminology can be confusing. Most types of tiles are made from clay or a mixture of clay and other materials.  They are then kiln-fired. The larger classification of “ceramic tiles” can be split into two groups: 1) porcelain tiles and 2) non-porcelain tiles. These non-porcelain tiles are frequently referred to as “ceramic tiles” by themselves, separate from porcelain tiles.  While porcelain tiles technically are a subset of ceramics, they are often referred to as porcelains because they are denser, stronger and tend to look nicer.

It’s important to understand that not all ceramic or porcelain tiles are suitable for all areas. Tile products generally are wear-rated from low to high (PEI hardness rating). Most manufacturers do meet international standards (but with a growing number of imports, some manufacturers do not comply).  And, it is important to understand if the tile is floor or wall tile.  Floor tile can be used on walls, but not vice versa.  Wall tiles are generally not suitable for the floor.  Wall tiles on the floor will usually crack and some are slippery, especially when wet, so they can also create a safety hazard.


Ceramic tiles (or non porcelain tiles) are generally made from red or white clay fired in a kiln. They are almost always finished with a durable glaze which carries the color and pattern. They can be naturally colored and left unglazed (like terra cotta) or they can have highly stylized and designed surfaces that are glazed.  They can be glazed in a high gloss or matte finish. These tiles are used in both wall tile and floor tile applications.  They are softer and easier to cut than porcelain, and usually carry a PEI 0 to 3 rating (see below). Ceramic tiles are usually suitable for very light to moderate traffic and generally have a relatively high water absorption rating making them less frost resistant. They tend to be more prone to wear and chipping than porcelain tiles.  And, because they often red or white underneath, when they do chip, it tends to show more.


PEI stands for Porcelain Enamel Institute and is a measure of hardness

Class 1:  No foot traffic.  Wall use only

Class 2:  Light traffic.  Bathroom wall and floor applications

Class 3:  Light to moderate traffic.  Walls, counter tops and floors normal foot traffic

Class 4:  Moderate to heavy traffic.  Good for all residential applications as well as medium commercial and light institutional

Class 5:  Heavy to extra heavy traffic.  All residential and all commercial and institutional use.

This process makes porcelain tile more dense, less porous, much harder and less prone to moisture and stain absorption than ceramic tiles. For these reasons, most porcelain tiles are suitable for both indoor and outdoor installations. Porcelain tiles usually have a much lower water absorption rate (less than 0.5%) than non-porcelain tiles making them frost resistant or frost-proof. Porcelain tiles are also harder to cut due to their density and hardness.

Full body porcelain tiles carry the color and pattern through the entire thickness of the tile making them virtually impervious to wear and are suitable for any application from residential to the highest traffic commercial or industrial applications. Porcelain tiles are available in matte, unglazed or a high polished finish.  They tend to look more real (many look like natural stone), have more intricate designs and they tend to cost a bit more than basic ceramic tiles.

This will give you an almost unlimited design possibilities.


Don’t forget….

Most people don’t realize that they should seal the grout.  This is true both for ceramic and porcelain tile.  Grout is essentially sand and over time, it can get dirty and even wear down or chip away.  Grout sealer helps protect the grout.  It has an antibacterial agent and seals it so that less dirt and grime gets in there.  It helps preserve the grout color and consistency.


heavy duty grout sealerYou should seal the grout shortly after it’s installed (often a couple of weeks later) and then try to reseal it every 1-2 years.  It’s and easy do-it-yourself project.  You just need grout sealer and a paint brush.



Both ceramic and porcelain tile are very easy to clean and maintain. They are much easier than natural stone which tends to be more porous and prone to mold (especially in wet shower areas).  Natural stone usually needs needs to be sealed and resealed often.


Regardless of whether you choose ceramic tile or porcelain tile for your decorating project you will find both types offer a large variety of shapes and sizes.  You can also get fancier with accent tiles and borders (sometimes called listellos). This will give you an almost unlimited amount of decorating options by mixing and matching different sizes, shapes, layouts along with borders and accent tiles to really add pizazz to your decor.

  1. Nice recap of the properties of tile flooring options. We love porcelain tiles for their consistency and textures that are being added making them less slip resistant. Very imnportant as we age in place to have slip resistant surfaces.

  2. hi debbie, do you recommend porcelain or laminate for a hair salon? I’m worried about grout staining with one and water damage to the other . thank you ,Paula G.

    1. Paula – Great question. But, tricky of course. Both have their pros and cons. Porcelain would probably hold up much longer. But, it is harder on your feet which could be a downside for those standing on their feet most of the day, and yes, you would need to seal the grout periodically. Laminate will be easier on your feet and a bit easier to clean, but it’s not waterproof, which can also be an issue for a hair salon (and an issue w/ daily cleaning.

      If you do laminate, get a very high quality one as it will have more protection and less likely to delaminate. If you do a tile, do a darker one (maybe a gray) w/ similar grout, and then w/ the grout darker, the “staining” won’t be so noticeable. It will be important that you seal the grout and reseal every year. This will prevent most of the staining.

  3. I just had glazed textured porcelain tile (light grey) installed. I have 3 little dogs and when they walk on it they leave smudgy prints. I assume it is from the oil in their footpads. These are indoor dogs and don’t have anything on their feet from outside. I can’t get these cleaned off! I have tried water-vinegar-dish detergent as recommended, and also 409.Tile store has never heard of such a thing. Help!!!!

    1. Judy – I wish I could help you. But, generally there is no warranty on reglazing floors and it doesn’t last long. We do not reglaze ourselves. I would recommend that you call a place that does the tile reglazing in your area and see what they recommend.
