The first step: Do a good job of hydropower basic engineering From a safety point of view, the bathroom water wire to go above than below. However, many people are eager to save energy, water and electricity go to the ground, and even open geochutes in the bathroom and cut round holes.
The second step: clean the base and wall of the house decoration waterproof, involving the balcony, kitchen, bathroom, but the focus is on the bathroom.
