How to Move a Toilet

The main methods for moving a toilet include the use of a toilet offset flange, raising the floor, modifying a multi-story drainage bathroom, modifying a same-floor drainage bathroom with a sunken tank, and installing a wall-mounted toilet. Details are as follows:

1. Toilet Offset Flange Method
   This method is suitable for small-scale, short-distance relocation, typically ranging from 10 to 30 centimeters, and not exceeding 40 centimeters. Its advantages include minimal modification and low cost, but it may affect flushing performance and increase the risk of clogging. There are two main types:

• Integrated Offset Flange: Suitable for short-distance relocation, generally not causing clogging within 20 centimeters.
• Side-pipe Offset Flange: The relocation distance should preferably not exceed 50 centimeters. For every 10 centimeters of relocation, at least half a centimeter of slope should be reserved in the pipeline to ensure smooth drainage. If an offset flange of more than 10 centimeters is used, a direct-flush toilet should be purchased to reduce the risk of clogging. During construction, mark the position of the offset flange and drill holes in the floor tiles. Lower the height of the original pipeline. The depth of the offset flange, usually about 5 centimeters, is mostly within the sand-ash layer. Clean the sand-ash thoroughly to prevent it from falling into the pipeline. Additionally, the hole for the offset flange should be larger than the toilet's drainage hole to prevent clogging.

2. Raising the Floor Method
   By constructing a height of approximately 180 millimeters (the specific value may be adjusted according to actual needs), new drainage pipes are laid within the floor, and the toilet's drainage outlet is connected to the new pipes. This method can address relocation needs over larger distances but occupies the height of the bathroom, requiring consideration of spatial comfort. During construction, ensure that the slope of the raised floor is reasonable to avoid water accumulation or poor drainage.

3. Multi-story Drainage Bathroom Modification
   This requires negotiation with the downstairs neighbor to drill holes in the floor slab and rearrange the toilet pipes downstairs. However, this method is highly impractical due to the involvement of the downstairs resident's rights, with 99% of neighbors unlikely to agree. It serves only as a theoretical alternative.

4. Same-floor Drainage Bathroom Modification with a Sunken Tank
   If the bathroom has same-floor drainage and a sunken tank structure, the toilet's drainage pipe can be directly adjusted within the sunken tank to allow for flexible toilet placement. This method does not require damaging the floor slab or affecting the downstairs resident but requires confirmation that the sunken tank space is sufficient and that the drainage slope meets standards.

5. Wall-mounted Toilet Modification
   The pipes do not run along the floor; instead, the toilet's drainage connects directly to the main vertical pipe. A sloped hole needs to be reserved, and a niche should be created above the water tank. This method is only suitable for short-distance modifications near the drainage pipe and requires advance planning for hiding the water tank, imposing high demands on spatial design.
