Can the Position of the Toilet Be Moved?

The position of the toilet can be moved, but it requires a comprehensive assessment based on legal regulations, technical conditions, and special needs, and it should not be moved arbitrarily.

Legal Regulation Aspect

According to the "Residential Design Code" GB 50096 - 2011, bathrooms should not be directly arranged above the bedrooms, living rooms (halls), kitchens, and dining rooms of lower-floor occupants to avoid causing adverse impacts on their lives. Meanwhile, the "Measures for the Administration of Interior Decoration and Renovation of Residential Buildings" explicitly prohibits converting rooms or balconies without waterproof requirements into bathrooms. If renovated in violation of regulations, a fine ranging from 500 yuan to 10,000 yuan may be imposed, and rework and rectification will be required. Therefore, moving the position of the toilet must comply with these legal regulations.

Technical Condition Aspect

Toilets and other sanitary fixtures need to be connected to sewage pipes with a diameter of 110mm, and a slope (usually ≥ 2%) must be ensured to avoid blockages. If flat pipes are used for relocation or the floor is raised, poor slope may lead to poor drainage or even bad odors. Raising the floor may also make the bathroom higher than other areas, posing a risk of water backflow. The new area needs to have a new waterproof layer. The waterproof height should be no less than 1.8 meters, and the number of brush coats should meet the standard (usually 2 - 3 times). Inadequate waterproofing can easily cause water leakage. When re-planning the water supply and drainage pipes, if the pipe routing is unreasonable, it may generate water flow noise. Improper sealing at the places where pipes pass through the floor slab may also cause condensed water to drip.

Common Relocation Methods

• Adding a Relocator: Small-scale relocation within 1 centimeter is acceptable. The probability of blockage doubles if the relocation distance exceeds 1 meter. A channel-type relocator should be selected. Construction should be carried out after tiling, and a 5-centimeter drop should be left for the pipes.
• Raising the Floor: Suitable for long-distance relocation, but a slope must be made to prevent blockages.
• Sunken Bathroom: The pipes can be freely adjusted, or wall-hung toilets can be used. The newly introduced flat trap design is only 8 centimeters thick and does not take up much space. It will not cause blockages even when relocated by 3 meters. If the relocation distance is ≤ 30cm, an eccentric relocator can be used, and the floor slope should meet the drainage requirements. At the same time, proper sealing of pipe joints and waterproofing should be carried out.
