Can the Toilet Position Be Moved During Renovation?

During renovation, the toilet position can be moved, but certain conditions must be met, primarily involving two key issues: drainage and waterproofing.

Drainage Requirements

The biggest challenge in relocating a toilet is the sewage disposal issue, which requires rearranging the drainage and sewage pipes without affecting the downstairs area. There are several ways to handle this:

• Same-floor drainage solution: On the same floor, create a 30-millimeter drop for every meter or so from the sewage pipe. If the distance is greater, design a bedding layer while considering the floor's load-bearing capacity. Alternatively, use a sewage pump to connect to different drainage outlets, using 32-millimeter pipes, and arrange the pipes through the ceiling or floor.
• Toilet relocation handling: For short distances (10-15 centimeters), a toilet shifter can be used, which is cost-effective and easy to install. If the relocation exceeds 15 centimeters, raise the floor and build a new platform to bury the pipes, with a diameter of at least 110 millimeters and a slope maintained between 2% and 3%. Alternatively, use a wall-mounted toilet, where the pipes run along the wall without raising the floor. Another option is to modify the pipes downstairs, but this requires the neighbor's consent and a new waterproofing test. For sunken bathrooms, the pipes can be directly modified within the backfill layer.
• Characteristics of different drainage methods: Same-floor drainage (sunken bathroom) has a floor approximately 40 cm lower than the regular floor, with drainage pipes within the home, making modifications relatively convenient. Cross-floor drainage (where drainage pipes pass through the floor for drainage) has more limited modification options.

Waterproofing Requirements

After arranging the drainage and sewage pipes, ensure the bathroom floor and walls are clean and level, and apply waterproofing materials. Both the shower area and dry area walls should be properly waterproofed. After application, conduct a closed-water test and observe the next day for any water level drop or leakage in the downstairs area. If there is none, the waterproofing is adequate, and tiles can then be laid.

Additionally, toilet relocation can make the layout more ideal and improve the flow after modification. However, costs vary depending on the relocation method, and if the position is moved too far, it may be more prone to clogging. Therefore, when moving the toilet position, various factors should be comprehensively considered to ensure renovation quality and subsequent usage effects.
