According to the traditional concept of Feng Shui in China, the bedroom should not be too big, because the aura of the human body is very weak when people sleep. Too big a room is easy to dissipate the energy of the human body too quickly, which is not conducive to health. Therefore, the big bedroom has not been advocated since ancient times.
If your bedroom is too big, you can make an appropriate partition, make a suite, and put the bathroom outside the suite, which is more in line with the concept of geomantic omen and avoids the bathroom going straight to the bedroom.
