How to solve feng shui without windows in bathroom?

There is no window in the bathroom. Water is the main element in the bathroom, and the room with more water is humid, which will lead to heavy gas energy retention, thus making its tendency stagnate. The bathroom space with windows can put green plants or hang pictures, which can ease the atmosphere and gather vitality in feng shui. Some residential bathrooms are fully open and closed, without windows, as long as the exhaust fan, if the exhaust fan is not turned on often, it is not good for health. I hope I can help you.
