There is a huge range of tiles on the market to choose from. A tiled back splash is a very popular choice as is a tiled kitchen floor. In addition to colour and size the material, from ceramic or stone to marble or slate, you decide on having will greatly add to the final look of your new kitchen.
An aspect to perhaps consider is the thickness of the tiles, especially on the floor as it would be preferable to marry up with the flooring of an adjacent room. Also, for example, behind your cooker it's advisable to avoid small mosaic tiles which require alot of grout that collects hard to clean grease etc.
