The kitchen door is 8 cm lower than the bathroom door. Does feng shui have an impact?

The kitchen is the main fire, the bathroom is the main water, and the water flows downwards, which means that the "water" in the bathroom will flow to the "fire" in the kitchen, which is incompatible. In the long run, kidney and bladder are prone to diseases, and their mood is unstable, their will is not strong, and they are prone to fear. The food always feels salty, and the cooking is not as delicious as before.
