The bathroom was never used more than one hour, but that does not mean the room approximately 1.5 m x 1.5 m, only with a bath or shower and toilet is enough. Like other rooms in the house, the bathroom was to consider his health. So not only functional, but also comfortable to use for the move.
Damp is a problem that most often become a threat in the bathroom. The air is dank and potentially cause mold fungi, which ultimately has the potential to also cause disease. Although the shower activity may only take 15-30 minutes, who would want to do it in the bathroom is dirty because of moss and fungus, too smelly?
The bathroom you see in this picture may be regarded as one example of a healthy bathroom. First, the bathroom is designed to be able to put a lot of sunlight, namely through the skylights. Enough sunlight to make the bathroom dry faster, so the mold, mildew, and bacteria do not multiply. In addition, power-efficient anyway, as long as the sun was shining, the bathroom does not need illumination from the lamp.
