The Toilet in the Building Can Be Moved

The position of the toilet in a building can be moved, but the method needs to be selected according to the drainage system of the bathroom, and there are certain limitations and risks.

There are mainly two types of bathroom drainage systems: same-floor drainage (sunken bathroom) and inter-floor drainage (where the drainage pipes pass through the floor slab for drainage). The methods and limitations for moving the toilet vary under different drainage systems.

Same-floor drainage: The bathroom floor is about 40 cm lower than the floor level. The drainage pipes are within one's own unit, making it relatively convenient for modifications. Pipes can be freely arranged within the lowered floor slab, with fewer restrictions on movement.

Inter-floor drainage: The floor slab cannot be excavated. If a toilet offset connector is used, the floor slab needs to be raised. It is not recommended to move the toilet more than 2 meters, and it is best to create a drainage slope.

The specific methods for moving the toilet are as follows:

• Toilet offset connector method: Suitable for small-scale and short-distance movement, usually ranging from 10 to 30 centimeters, not exceeding 40 centimeters. It involves minimal modification and low cost, but it may affect the flushing effect and increase the risk of blockage. During construction, a slope of 1% - 3% needs to be reserved. Moving it a short distance of 10 centimeters is the safest, and if it exceeds 20 centimeters, the floor needs to be raised by 12 centimeters to increase the pipe slope.
• Floor raising method: By building a base platform 180 - 200 millimeters high to embed the sewage pipe, it is suitable for longer-distance movement. This method allows for flexible layout but raises the floor, affecting aesthetics and convenience of use.
• Floor-drain to wall-drain conversion: Connect the toilet directly to the sewage riser. The toilet can only be moved to the adjacent wall of the sewage riser, not to the opposite wall. After modification, the toilet is less likely to get blocked. This method is suitable for both same-floor and inter-floor drainage systems, but converting to a wall-drain requires building a false wall, which can be combined with a niche to create storage space.
• Modifying pipes in the lower unit method: Applicable to inter-floor drainage systems, it strictly requires the consent of the occupants and property management of the lower unit. Professional personnel should carry out the pipe modifications in the lower unit.
