How to Relocate and Separate the Toilet

Relocating and separating the toilet requires toilet displacement and layout adjustments, with the following specific methods:

I. Toilet Displacement Methods

1. Using a Displacement Connector This method is suitable for bathrooms with inter-floor drainage (i.e., pipes located above the ceiling of the floor below). The floor slab needs to be raised (usually by 5-10 cm) to bury the displacement connector. It is recommended that the displacement distance does not exceed 2 meters, otherwise, blockages are likely to occur. During installation, a drainage slope (slope ≥ 2%) should be set to ensure smooth sewage discharge.

2. Converting Floor Drainage to Wall Drainage Connect the toilet's sewage pipe to the adjacent wall and discharge it into the main riser through pipes inside the wall. This method is suitable for both same-floor and inter-floor drainage. After modification, the pipes are hidden within the wall, making them less prone to blockages. However, a false wall (approximately 15-20 cm thick) needs to be built to encase the pipes, which may occupy space.

3. Modifying the Sewer Pipes This requires negotiation with the residents on the floor below to break open their ceiling and adjust the pipe positions. This method is suitable for short-distance displacement (e.g., within 1 meter), directly shortening the sewage discharge path with basically no risk of blockages. However, the construction is complex and relies on the cooperation of neighbors.

4. Raising the Floor For non-sunken bathrooms (i.e., the original floor has no recess), fill with cement mortar (height approximately 10-15 cm) to bury the pipes and create a slope. This method can hide the pipes but will raise the floor level, so attention should be paid to coordinating the height of the door frame.

II. Separation Layout Adjustments

1. Externalizing the Washbasin Move the washbasin outside the bathroom door and hide the pipelines through wall drainage. This design saves internal space and achieves more thorough dry-wet separation, suitable for small apartments. The position of the wall drainage should be planned in advance to ensure smooth drainage.

2. Dry-Wet Separation Use glass partitions or shower curtains to divide the shower area, preventing water stains from spreading to the toilet and washbasin areas. Glass partitions offer better sealing but require regular cleaning; shower curtains are low-cost and flexible but have weaker splash prevention effects.

3. Four-Section Separation Design In bathrooms with sufficient space (e.g., an area ≥ 8 square meters), completely separate the toilet, shower, washroom, and laundry area to form independent functional areas. This design ensures non-interfering movement paths but requires re-planning of water and electricity lines, with higher costs.

III. Key Considerations

• Confirm the Drainage Type: Before construction, it is necessary to determine whether the bathroom has same-floor drainage (pipes on the same floor) or inter-floor drainage to choose the appropriate displacement method.
• Waterproofing Treatment: After modifying the sewer pipes or floor drains, re-apply waterproof coating to the floor and walls (height ≥ 1.8 meters) and conduct a 48-hour water closure test.
• Synchronous Renovation of Water and Electricity: Relocating and separating involve adjustments to water pipes and circuits. It is recommended to plan the positions of sockets and switches in advance to avoid rework later.
