Can the Position of an Indoor Toilet Be Moved?

The position of the toilet in an indoor bathroom can be changed, but it depends on the situation and is subject to many restrictions, including technical conditions and legal regulations.

Technical Limitations

• Short-distance relocation: If the relocation distance is between 10 and 15 centimeters, a toilet offset connector can be used. It is cost-effective and easy to install. However, attention should be paid to the pipe slope. A channel-type offset connector should be selected, and construction should be carried out after tile laying. The pipe should have a 5-centimeter drop. Moreover, when the relocation distance exceeds 1 meter, the probability of blockage doubles.
• Long-distance relocation: If the relocation distance exceeds 15 centimeters, there are several approaches. One is to raise the floor, build a new platform to bury the pipes. The pipe diameter should be at least 110 millimeters, and the slope should be maintained between 2% and 3%. However, this method sacrifices some ceiling height. Another option is to use a wall-mounted toilet, where the pipes run along the wall, eliminating the need to raise the floor. This is suitable for relocations of more than 50 centimeters. For sunken bathrooms, which are more flexible, the pipes can be directly modified in the backfill layer. It is also possible to modify the pipes downstairs, but this requires the consent of the neighbors and a new waterproofing test.

Legal Restrictions

According to the "Residential Design Code" GB 50096 - 2011, bathrooms should not be directly arranged above the bedrooms, living rooms (halls), kitchens, and dining rooms of the lower-floor occupants. Meanwhile, the "Measures for the Administration of Interior Decoration and Renovation of Residential Buildings" explicitly prohibits converting rooms or balconies without waterproofing requirements into bathrooms. Illegal renovations may face fines ranging from 500 yuan to 10,000 yuan and require rework and rectification.

Other Considerations

If relocation is carried out, proper waterproofing treatment is also necessary. The waterproofing height in the new area should be no less than 1.8 meters, and it should be applied 2 - 3 times. When re-planning the water supply and drainage pipes, care should be taken to avoid generating water flow noise, and proper sealing should be done at the places where the pipes pass through the floor. If the relocation distance exceeds 15 centimeters or elbows are used, the risk of blockage increases. It is advisable to communicate well with the lower-floor occupants before relocation and ensure proper sealing during installation to prevent odors in the bathroom.
