Layout Design of Mobile Toilet Position

In layout design, the position of the mobile toilet should be comprehensively considered based on the drainage type, relocation principles, and methods, as detailed below:

1. Clarify the Drainage Type

Toilet drainage in bathrooms is divided into same-floor drainage and inter-floor drainage. Same-floor drainage completes drainage within the same floor, with all drainage branch pipes connecting to the main drainage pipe without penetrating the floor slab, making it convenient for rectification and maintenance, commonly found in sunken bathrooms. Inter-floor drainage requires penetrating the floor slab to connect to the main drainage pipe on the floor below, involving neighbor relations for rectification and being more cumbersome to operate.

2. Follow the Principles of Toilet Relocation

1. Determine the relocation range based on the floor slab reduction type: Without floor slab reduction, the toilet relocation range is typically between 100 - 300mm. With partial floor slab reduction, the toilet position can be relatively freely adjusted within the reduced area, but overall adjustment is limited. With overall floor slab reduction (sunken box), the toilet position can be arranged and adjusted as needed.
2. Determine the relocation method based on the drainage method: Same-floor drainage is suitable for directly modifying pipes or using relocation devices. Inter-floor drainage is suitable for relocation devices, raising the floor, converting floor drainage to wall drainage, modifying sewage pipes, and negotiating with neighbors to modify pipes.
3. Determine the relocation distance based on the layout of the apartment: The longer the toilet relocation distance, the longer the horizontal drainage pipe, and the higher the likelihood of sewer blockage. The principle of relocation is to avoid relocation as much as possible, relocate short distances rather than long ones, and it is recommended to control the relocation distance within 30 centimeters, with a maximum of no more than 1 meter.

3. Choose the Appropriate Toilet Relocation Method

1. Use a toilet relocation device: An integrated relocation device is suitable for short-distance relocation, used for relocations within 20 centimeters. For edge-pipe relocation devices, the relocation distance should preferably not exceed 50 centimeters, with at least a half-centimeter slope reserved for every ten centimeters of pipe relocation. When using a relocation device of more than ten centimeters, a straight-drain toilet should be purchased. For inter-floor drainage, using a relocation device requires raising the floor slab, and the relocation distance is not recommended to exceed 2 meters. It is best to create a drainage slope.
2. Negotiate with the downstairs neighbor to modify pipes for inter-floor drainage: You can negotiate with the downstairs neighbor to drill holes in the floor slab and rearrange the toilet pipes, but the success rate is extremely low.
3. Directly modify pipes for same-floor drainage: In bathrooms with a sunken box, pipes can be directly lengthened or shortened for relocation.
4. Convert floor drainage to wall drainage: Connect the toilet to the sewage riser, with the position only movable to the adjacent wall of the sewage riser. After modification, the toilet is less likely to block, suitable for both same-floor and inter-floor drainage, and can be combined with niches to create storage space.
5. Wall-mounted toilet: The pipes do not run on the floor but are directly connected to the main riser, with a reserved inclined slope hole, suitable for short-distance modifications with the sewer pipe.
