Indoor Mobile Toilet Solution

The solution for indoor mobile toilets (toilet relocation) should be selected based on the drainage method of the bathroom. Relocation is simpler for same-floor drainage, while for inter-floor drainage, methods and costs need to be comprehensively evaluated.

1. Same-Floor Drainage (Sunken Bathroom)

The drainage pipes for same-floor drainage are located within your own bathroom, making relocation relatively simple as you can directly modify the drainage pipes. This method does not require consideration of the opinions of the downstairs owner, has lower construction difficulty, and has less impact on the overall layout of the bathroom, making it an ideal relocation solution.

2. Inter-Floor Drainage (Drainage pipes pass through the floor slab and are located on the ceiling of the downstairs neighbor's home)

1. Use of a Relocator
   Suitable for short-distance relocation, it is recommended not to exceed 40 centimeters as longer distances are prone to blockage. A slope of more than 3% should be created at the pre-embedded relocator location to facilitate drainage, and proper waterproofing should be done. The height of the relocator's flat pipe is about 4 centimeters. If there is no underfloor heating, the ground can be lowered to flatten the pipe; if there is underfloor heating, the entire floor needs to be raised.
2. Wall-Hung Toilet (Wall-Drain Toilet)
   Requires a wall-drain toilet. The water tank is positioned high with strong flushing power, suitable for long-distance relocation and less prone to blockage. However, the toilet can only be relocated to the adjacent wall of the sewage riser and not to the opposite wall. Installation requires the construction of a false wall, which can be combined with niches to create storage space, increasing the practicality of the bathroom.
3. Raising the Floor
   For long-distance relocation, a slope needs to be ensured, requiring the construction of a new floor platform in the toilet area to raise the floor. However, after raising the floor, it becomes inconvenient to use and prone to tripping, so caution should be exercised, especially in households with elderly people or children.
4. Relocation by Drilling a New Hole in the Floor Slab
   Directly modify the downstairs sewage pipe to the desired location. This method yields the best results but is the most difficult. It requires the consent of the downstairs owner; otherwise, it is difficult to implement and may involve approval from property management and other relevant departments.

3. Precautions

After relocation, be cautious when choosing a siphon toilet as it has high requirements for drainage smoothness and is prone to blockage if the pipe conditions are not good. Relocation may affect waterproofing, so reinforcement is necessary. According to the 'Measures for the Administration of Interior Decoration and Renovation of Residential Buildings', it is prohibited to convert a room without waterproofing requirements into a bathroom, and relocation must not interfere with the normal use of the downstairs owner. If the relocation distance is too far, it is recommended to prioritize wall-hung toilets or re-plan the bathroom layout.
