A bathroom located above the bedroom is not the best feng shui set-up. An important factor to consider in looking for feng shui cures, in this case, is how busy the upstairs bathroom will be.

Having the kitchen and the bathroom doors face each other is very bad feng shui, indeed. One does not need to know much about feng shui to intuitively understand that this is not a good set-up for a healthy home.

A bathroom in the West or Northwest bagua areas is not bad, or worse feng shui, than a bathroom in any other feng shui bagua area of the house. Bathrooms do have a predominant Water feng shui element energy that can weaken the Metal feng shui element.

Applying this method is challenging, but not a reason for you to not treat it properly. It is important to understand that the bathroom has "draining energy".
