For me kitchen tile should be something that is hard for to slip in. I want something that can be cleaned easily, kitchen is a hectic mess in any house so there will always be dirt everywhere. Kitchen floor will always get wet because of spills. The tile should be textured to prevent slip or at least have a non slip surface.
You will dirty it forever until you make over it again and dirty it again so choose darker color with a wide grout color to hide the dirty colors or you can simply clean them everyday.
Kitchen Floor Tile
My first suggestion on kitchen floor tile is the porcelain and ceramic tile. They are hard and very durable. But this advantage can be a drawback too, in case you fall on it you will likely share your bump on your head with others in the world who already experience it before hand. These tile come with a wide variety of colors. They also comes with a variety of styles too so you will have your fun designing your kitchen floor.
Second recommendation on my kitchen floor tile is the slate tile. Slate is natural stone tile, They are durable and tough for your everyday kitchen business. It main advantage is that they came with anti stain surface and anti slip surface. They have varying texture but a little color choice (charcoal, gray, rust and green).
Next recommendation for kitchen floor tile the granite. This is another durable choice and they invulnerability to acidic liquid like coffee or soda. Again, color choice is limited but you got they look good with the gloss. They still have their own weakness though, quartz. This are those tiny stone that latched into your shoes. They can scratch the surface so you need to clean your granite floor regularly.
