A great idea for a lovely splashback is to use pressed tin.  It comes in a range of designs, see www.pressedtinpanels.com for fully range.  It is recommended that the panels are powdercoated as they are porous and will absorb moisture, fats and oils without some type of sealant.  It also makes cleaning a breeze with just a soft cloth and hot soapy water.  For further information please don’t hesitate to call Restoration House on 07 49211338
