When two doors are opposite each other the feng shui energies flow faster in and out of the spaces guarded by the doors. This is why another direct door alignment - the front door aligned with the back door - is also considered bad feng shui.
What you have in the case of a bathroom door facing the kitchen door is the energies of the bathroom (release, purification, letting go, etc) mingling with the precious energies of the kitchen (nourishment, cooking, warmth, love & support).
In simple terms, you have undesirable odors from the bathroom affecting the energy of the kitchen - the heart of the home. In more complex terms, you also have the energies of the water feng shui element of the bathroom going against the fire feng shui element of the kitchen.
It will be harder to maintain optimum health and loving communication levels in a house with this set-up, but it does not mean you cannot do your best to even slightly improve the situation.
Your goal is to create as much division as possible between the kitchen and the bathroom, and here are some simple feng shui tips to consider if you cannot move out (or plan a renovation).
- Always keep the bathroom door closed.
- Be sure your bathroom is always clean and a pleasure to be in.
- Find a creative way to define the boundary between the bathroom and the kitchen. Look into a screen, a tall plant or a bamboo curtain, for example (if your kitchen has an open entryway) or doors with no glass (if the kitchen doors have glass inserts).
- Different wall paint color on the two opposing walls can work well to define and separate the two areas.
- Creating a focal point in between the two areas will draw the energies away from mingling and bring a sense of beauty. Work with big scale art and choose colors and images according to your bagua area requirements.
If you own a home, look into the possibility of at least a minor renovation to remedy this situation. And, if you rent, you will sure be wise to avoid this set-up in the future!
