For cabinets I owe much to Archidigm and Odin's great tutorials. But we make cabinets differently and don't generally have a splashback but a number of rows of tiles above. Whilst you can have a variable height you only have one option and you can't have a different height to your cabinet and tile height. (well you could if you cab height was the wall base height and the tile height was the top of wall but you would have to manually grab each side and pull them up to get the tile height extension. Actually I just tried that and it might work okay for some).
