(I'm strikethrough:totally mildly obsesse with kitchens at the moment.)
Do you have tiles on the wall behind your kitchen worktop or just paint? Or tiles/splasback just behind the hob and/or sink?
I currently have tiles, but prefer the look without. Does the wall get grubby and hard to clean without tiles? I find random speckles of heaven knows what all over my tiles - worry my walls would look a state if I just had paint.
