New House Toilet Relocation
The relocation of toilets in new houses mainly involves moving the toilet bowl, and it is necessary to choose an appropriate method according to the drainage method. There is also a risk of blockage, so it is not recommended to make changes unless absolutely necessary.

Same-Floor Drainage (Sunken Bathroom)
The bathroom floor is about 40 cm lower than the floor level of the rest of the house, and the drainage pipes are located within one's own unit, making it convenient to make changes. Pipes can be freely arranged within the lowered floor layer for relocation with relatively few restrictions. This method does not require consideration of the floor slab structure and allows for relatively free adjustment of the toilet position. As long as the pipe routing is reasonably planned within the lowered floor layer, construction is relatively simple and has a minor impact on the overall indoor structure.
Inter-Floor Drainage (Drainage pipes pass through the floor slab for drainage)
- Using a toilet bowl relocator: The change is relatively simple, but the toilet bowl cannot be moved too far; otherwise, it is prone to blockage. It is recommended that the relocation distance does not exceed 2 meters, and it is best to create a drainage slope. Since the floor slab cannot be excavated, using a relocator requires raising the floor slab, which may affect the indoor floor height and user experience.
- Converting floor drainage to wall drainage: Connect the toilet bowl directly to the sewage riser. The toilet position can only be moved to the adjacent wall of the sewage riser and not to the opposite wall. After the change, the toilet bowl is less likely to be blocked, and this method is suitable for both same-floor and inter-floor drainage. However, converting to wall drainage requires building a false wall, which can be combined with niches to create storage space and increase space utilization.
- Changing the pipes in the neighbor's unit: Go to the neighbor's unit and directly change the sewage pipe to the desired position. This method is simple in that if the neighbor agrees, the difficulty of the change is low. However, the challenge lies in getting the neighbor's consent, and it involves property management regulations, with a relatively high risk of legal and neighbor disputes.
- Raising the floor method: By building a base platform 180 - 200 millimeters high to embed the sewage pipe, this method is suitable for longer relocation distances and allows for flexible layout. However, it will raise the floor, affecting aesthetics and convenience of use, such as potentially affecting the opening and closing of doors.
- Re-drilling a hole for relocation: When there is sufficient space below the bathroom floor slab and with the consent of the downstairs owner, re-drilling a hole for relocation can be chosen. A new sewage outlet is opened below the floor slab, and the pipe is led to the new toilet position. At the same time, it is necessary to ensure that the newly opened sewage outlet is connected to the original sewage system.
If relocation is necessary, the method should be chosen according to one's own drainage method, and professional personnel should carry out the construction. A waterproof test should be conducted, and attention should be paid to the sealing and smoothness of the pipes.
