Yes, wall tiles are fired at a lower temperature and have higher water absorption properties on the tile body. Most wall tiles are lighter and have pressed edges. Wall tiles also often come in more gloss or satin finishes, to make them easier to clean. Floor tiles are denser, heavier to hold and have a stronger surface that can handle heavier traffic. Floor tiles more often come in Matte, Grit, Rock or Structured finishes, to make them more slip-resistant.
If you’re not sure what direction to go a good rule of thumb is “if its good for the floor, its good for the wall. But never use Wall tiles for floors”.
