I have several boxes of wall tile and I would like to use some on a floor. Is this okay? What is the difference?
No because when wall tile gets wet it gets very slipery. You would be creating an ice scating rink.
unless it is porcelain the make up of the tile is not strong enough to withstand the weight and traffic it would be up under
First, wall tiles are thinner than floor tiles. Because of gravity, wall tiles are made slightly thinner to make adherence to your wall easier. Wall tiles are also often more porous on their adhesive side than ceramic floor tiles, again for ease of installation. Ceramic floor tile on the other hand is made thicker for application to flat surfaces. It is also set with a different mixture of thinset mortar. You can find most styles of floor tile made for walls as well so that you can match your border to your floors. Consult with a ceramic floor tile specialist to see if they can find the style you are looking for in both ceramic floor tile and ceramic wall tile.
Wall tiles are to soft for floors they break easily. Floor tiles are hardened. I'm a builder 30 years.
Don't do this under any circumstances. Wall tiles are much thinner and are designed for wall use only. When a floor tile is designed they are much thicker and have also been stressed to take a weight. As other contributors have said wall tiles generally have a smooth finish and are therefore slippy whereas wall tiles will always have some form of anti-slip format. I don't know where you got your wall tiles but most shops will be happy to take them back and exchange them for other products such as floor tiles.
