Wall & Floor tiling can have a big impact on any room and you should take a few things into consideration, like will there be a chance that the floor will be getting wet frequently, for example near a sink or the front entrance. Then you should consider getting non slip tiles.
You should think of the size of the tile, what finish is on the tile, shiny or matte. Whether the tile will be outside or inside and if it will be used close to a fireplace.
Wall tiles can really make all the difference to your kitchen or bathroom and really set off the room as you can see from these photos.
