How to Move the Toilet Layout During Renovation

When renovating and moving the toilet layout, it is mainly necessary to select an appropriate toilet relocation method based on the bathroom's drainage system, while fully considering the risks associated with relocation and subsequent handling issues.

Same-Floor Drainage (Sunken Bathroom)

In same-floor drainage systems, the drainage pipes are located within your own bathroom, making modifications relatively convenient. You can directly relocate the toilet and change the position of the drainage pipes. Since the pipes are within your own space, there is no need to consider factors such as the downstairs neighbors, allowing for relatively free and flexible adjustments to the toilet layout.

Inter-Floor Drainage (Drainage pipes pass through the floor slab for drainage)

• Using a Toilet Relocator: This is a relatively simple modification method, but there are limitations on the relocation distance. It is not recommended to exceed 2m (some say the maximum should not exceed 40 centimeters). To facilitate drainage, it is best to create a drainage slope, with a slope of more than 3% at the location where the relocator is embedded, and be sure to do a good job of waterproofing; otherwise, leakage problems may easily occur.
• Floor Drain to Wall Drain Conversion: Connect the toilet directly to the sewage riser, but the toilet can only be moved to the adjacent wall of the sewage riser, not to the opposite wall. This modification method is applicable to both same-floor and inter-floor drainage systems, and the toilet is less likely to get clogged after modification. Additionally, converting to a wall drain requires building a false wall, which can be combined with niches during renovation to create storage space and increase practicality.
• Directly Lengthening or Shortening the Pipes: In sunken bathrooms, the floor slab is relatively low, and the interior floor can be modified. This method can be chosen to relocate the toilet and adjust the toilet layout.
• Directly Modifying the Sewage Pipes in the Neighbor's Home: If you can obtain the neighbor's consent, this modification method is relatively easy. However, it is quite difficult to get the neighbor's agreement, as it involves the neighbor's space and rights.
• Re-drilling Holes in the Floor Slab for Relocation: Subsequent吊模 (formwork hanging) treatment is required, but most downstairs owners find it difficult to accept this method, as it may affect the downstairs ceiling.

Before relocating the toilet, it is necessary to fully evaluate the bathroom's drainage system, relocation distance, and construction conditions. Relocation may increase the risk of clogging and also require handling issues such as waterproofing and neighborly consultations. If not necessary, it is not recommended to easily carry out relocation operations.
