Relocation of Toilet Position in New House

The position of the toilet in a new house can be relocated, but it is necessary to choose an appropriate method based on the drainage system and pay attention to relevant considerations.

If the bathroom in the new house has a same-floor drainage system (where the drainage pipes are located within the bathroom of one's own home, also known as a sunken bathroom), relocating the toilet is relatively straightforward. One can directly relocate and modify the drainage pipes or choose to extend or shorten the pipes for relocation. This method involves minimal changes to the pipes and has relatively low construction difficulty.

If the bathroom has an inter-floor drainage system (where the drainage pipes pass through the floor slab and are located on the ceiling of the bathroom of the downstairs neighbor), there are several relocation methods:

• Using a toilet offset connector: This method is relatively simple, but the relocation distance should not be too far. It is recommended not to exceed 40 centimeters (some sources suggest not exceeding 2 meters). If the relocation distance is too long, it may lead to blockages later. A slope of more than 3% should be created at the location where the offset connector is embedded to facilitate drainage, and waterproofing must be done. For short-distance relocations of 10 centimeters, it is the safest option. If relocating more than 20 centimeters, the floor must be raised by 12 centimeters to increase the pipe slope.
• Converting floor drainage to wall drainage: Connect the toilet directly to the sewage riser. The toilet can only be relocated to the adjacent wall of the sewage riser and not to the opposite wall. After modification, the toilet is less likely to block, and this method is suitable for both same-floor and inter-floor drainage systems. However, converting to wall drainage requires building a false wall, which can be combined with niches to create storage space during renovation.
• Relocating by creating a new hole in the floor slab: Directly create a new hole in the floor slab and perform formwork and pouring later. However, this method is difficult to arrange because most downstairs homeowners are unwilling to accept it.

Regardless of the relocation method used, a national standard slope of 0.02 must be ensured after relocation to ensure smooth drainage, and waterproofing must be done properly to prevent leakage problems. At the same time, relocating a toilet is a highly specialized task, and professional construction is essential for reliability. If possible, it is best to avoid relocation because it is not only troublesome but also prone to blockages if not done properly, and it has higher requirements for waterproofing.
