Description
Bathroom Structure and Assembly Method This work relates to a bathroom, particularly a bathroom structure and its assembly method that can prevent sewage from leaking down to the space of the downstairs resident through a same-floor drainage mechanism. There are many reasons for water leakage in apartment buildings. Apart from leaks in pipes or joints buried in the walls, most leaks occur in bathrooms. This is mainly because bathrooms use water very frequently, and their drain pipes and sewage pipes usually run down through the floor slabs before bending and converging into the public sewage pipes for discharge. When leaks occur in the bathroom floors, walls, or sewage pipes of the upper floors, they not only damage the ceiling structure of the lower floors and cause dirt, but also often damage furniture. Therefore, water leakage can easily lead to disputes between upstairs and downstairs residents, affecting their relationship and even resulting in lawsuits. In view of this, in order to provide a structure that is different from conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development, resulting in this creation. One objective of this invention is to provide a bathroom structure and its assembly method to solve the problem of water leakage from the bathroom of an upstairs resident to the downstairs resident's space. This is achieved by connecting a raised floor to the bottom of a main body, forming a first space and a second space on the front and rear sides of a rear side panel, respectively. A drainage channel is provided on the floor panel, and at least one through hole is provided on the surface of the rear side panel. This allows the drainage channel and at least one bathroom fixture in the first space to be interconnected with at least one pipe in the second space, thereby draining sewage into the second space. Furthermore, by laying a floor panel flat within a waterproof tray, when water leaks from the surface of the floor panel, it can catch the downward-leaking sewage and drain it horizontally, thus preventing sewage from leaking downwards into the downstairs resident's space.
