Nothing competes with the bedroom. Most of us spend a third of our lives in this one spot in the house so it almost always ranks first in terms of prioritizing what room the evaluate first.
The next most important room, according to feng shui theory, is the room you spend most of your waking hours in. Many people these days have home offices where they genuinely spend hours per day or night, generating income.
Usually ranking third, the entrance that you actually use will also be revealing in how well or poorly you do in that residence. Even though you only pass through the entrance and do not spend much time there, it is the "mouth" of the house so you carry the outside energies into your house through this passage way and it is very telling in terms of how you will function in your space. Just as an example, some homes indicate at the entrance that the occupants will experience a lot of arguments or sickness.
A living room is an important room to look at if you actually spend a few hours per day sitting there and many people do just by watching their evening line up of televation shows. And yet other people hardly spend anytime in their living rooms unless they are entertaining guests.
Bathrooms and closet areas may be the least important from a feng shui stand point and every house will have several negative zones. In the design phase it is ideal to locate the bathrooms, storage areas and closets in what are the potentially negative zones.
A kitchen, the "hearth of the home" used to be a lot more impactful on residents when people cooked and ate most of their meals at home. Nowadays, with lifestyles so drastically different than they were even just fifty years ago, the kitchen and dining room are not going to influence your health and wealth--just because you don't spend much time there.
No matter how you use your rooms or how often, it is ideal to feel good about each room, the colors, the contents of each room, the lighting and the views. There is a subjective aspect to feng shui and you should make a point of creating spaces that are functional, attractive, and comfortable for all your purposes.
