Can the Toilet Position in a New House Be Moved?

The toilet position in a new house can be moved, but it depends on the circumstances. Details are as follows:

Same-floor drainage If the bathroom in the new house has same-floor drainage (the drainage pipes are located within the bathroom itself, i.e., a sunken bathroom), moving the toilet is relatively straightforward. You can directly adjust the toilet position and change the drainage pipes, with ample room for operation and relatively low cost and difficulty for the modification.

Inter-floor drainage If it has inter-floor drainage (the drainage pipes pass through the floor slab and are located on the ceiling of the bathroom of the downstairs neighbor), specific methods are required for moving the toilet:

1. Using a toilet offset connector: Suitable for short-distance moves (10-15 cm), it is low-cost and easy to install. It can also be used for moves of up to 40 cm, but note that moves exceeding 15 cm or having too many elbows increase the risk of blockage; the area where the offset connector is embedded needs a slope of more than 3% for proper drainage; and strict waterproofing must be done after the move.
2. Raising the floor: By building a new platform to embed the pipes (with a pipe diameter of at least 110 mm), maintain a slope of 2%-3%. This method sacrifices floor height, so it should be chosen with caution if the house itself has a low ceiling height; and the raised floor makes it inconvenient to use and increases the risk of falls.
3. Using a wall-mounted toilet: The pipes are laid along the wall, eliminating the need to raise the floor, and it is suitable for moves of more than 50 cm. However, it requires that the new toilet position be relatively close to the original pipes, the pipe-laying process is more complex, and the cost is higher.
4. Cutting a new hole in the floor slab for relocation: This requires the consent of the downstairs neighbor. After construction, formwork support should be carried out and a new waterproofing test should be done. This method involves structural modifications, has a higher risk, and requires strict adherence to construction specifications.

Other considerations If the bathroom has not been renovated yet and there is a certain distance from the downstairs bathroom, you can achieve a position change by adjusting the layout of the sewage pipes (such as installing elbows to change the direction of the toilet sewage pipe). However, note that the height of the floor raise should be controlled to avoid creating a height difference with the external floor. All modifications should be planned and carried out by professional decorators. It is not advisable to move the toilet position unless necessary, as improper relocation can easily lead to drainage blockages, significantly increase the waterproofing requirements, and raise the maintenance costs in the later stage.
