Special Diagram for Toilet Relocation

The relevant diagrams and methods for relocating a toilet (马桶) mainly involve the following types, with textual descriptions for reference:

1. Using a Toilet Offset Connector for Inter-floor Drainage

A toilet offset connector is a commonly used tool for short-distance relocation (recommended within 40 cm). Its core structure is a flat pipe device. The diagram clearly indicates how it connects the original toilet drain outlet to the new position. The flat pipe typically has a diameter of 110 mm and a height of about 4 cm. During installation, it is necessary to lower the local floor or raise the entire floor to provide sufficient space. The slope of the flat pipe must strictly adhere to the GB50242-2002 standard, which specifies a height difference of 12 mm per meter of pipe, to ensure smooth drainage. For short-distance relocation, a ready-made offset connector (ranging from 2 to 10 cm in size) can be used directly. For long-distance relocation, the flat pipe needs to be cut on-site and the slope adjusted accordingly.

2. Wall-mounted Toilet Relocation

This method is suitable for long-distance relocation without concerns about blockages. The diagram shows that the principle involves rerouting the pipes to the wall drainage riser, completely avoiding the floor pipe layout. During construction, a false wall needs to be built to conceal the pipes, with a thickness generally matching the depth of the toilet tank (about 20 to 30 cm). The false wall design can incorporate niches to increase storage space, enhancing practicality. This method has minimal impact on ceiling height but requires advance planning of water and electrical lines.

3. Raising the Floor for Relocation

For long-distance relocation scenarios where an offset connector cannot be used, the diagram often shows the construction of a new platform in the toilet area (with a height of about 15 to 20 cm) to ensure proper drainage slope. The platform surface must be waterproofed, and drainage pipes must be pre-embedded to connect to the main riser. This method is suitable for inter-floor drainage but occupies some ceiling height, so the feasibility must be assessed based on the actual height of the bathroom.

4. Relocation in Sunken Bathrooms

Sunken bathrooms (with same-floor drainage) offer significant advantages for relocation. The diagram illustrates that the pipes can be directly extended or shortened within the sunken box without penetrating the floor slab. During construction, the existing pipes in the sunken box must be cleared, the drainage path replanned, and the new pipes secured with cement mortar. This method has no impact on neighbors downstairs but requires ensuring the integrity of the sunken box's waterproof layer to prevent future leaks.

Precautions

• Relocation Distance Limitations: The longer the relocation distance, the higher the precision requirement for the slope. It is recommended not to exceed 2 meters; otherwise, drainage issues or blockages may occur.
• Inter-floor Drainage Pipe Modification: If it is necessary to penetrate the floor slab for pipe modification, consent must be obtained from neighbors downstairs, and proper waterproofing of the floor slab must be carried out.
• Diagram Reference: For specific construction details, refer to the illustrations in the search results, paying particular attention to pipe connection methods, slope markings, and waterproofing nodes.
