Fire and water
The main consideration in the kitchen is that the water and fire elements do not clash; for example, the sink and stove should not be directly opposite each other. Even if it is convenient, such a design will cause arguments and conflict between members of a household. The water-fire clash may also occur (but to a lesser degree) when the stove and sink are next to each other.
The same water-fire clash would happen if a water appliance - a refrigerator, water dispenser or dishwasher - was directly opposite a fire appliance - the oven or stove.
You need to keep a sense of perspective, though; focus only on the main appliances and do not worry about the location of your toaster, rice cooker, kettle or microwave oven.
If you cannot move the major appliances, consider introducing an element of wood to alleviate the water-fire clash. In the production of the five elements, water produces wood, which then feeds fire.
Place a wooden or green mat in between the appliances. The problem would be solved if you had wooden flooring or green tiles.
For clashing appliances that are next to each other, consider placing a strip of wood between them.
