Toilet Renovation and Relocation

Toilet renovation and relocation, also known as toilet displacement, refers to the operation of changing the original installation position of the toilet. The common methods and key points are as follows:

Using a Toilet Displacement Device

An integrated displacement device is suitable for short-distance displacement, typically used for displacements within 20 centimeters. A 100-diameter flat pipe is added in the middle, and the length of the flat pipe is adjustable. Short displacement distances usually do not cause blockages. For side-pipe displacement devices, the displacement distance should preferably not exceed 50 centimeters. For every 10 centimeters of displacement, at least a 0.5-centimeter slope should be reserved in the pipeline to ensure smooth drainage. Additionally, when using a displacement device of more than 10 centimeters, a straight-flush toilet should be purchased. The displacement device method is suitable for small-scale, short-distance displacements, usually ranging from 10 to 30 centimeters and not exceeding 40 centimeters. It involves minimal alterations and low costs but may affect the flushing effect and increase the risk of blockages. A slope of 1% to 3% should be reserved during construction.

Re-piping in Inter-floor Drainage Bathrooms

You can negotiate with the neighbor downstairs to drill holes in the floor slab and re-lay the toilet pipeline downstairs, although 99% of neighbors downstairs will not agree. The method of changing the pipeline downstairs is applicable to inter-floor drainage and requires strict consent from the occupants downstairs and the property management. Professional personnel should carry out the pipeline modification downstairs, which carries a high risk of legal and neighborhood disputes.

Bathrooms with Sunken Floors in Same-floor Drainage

Same-floor drainage displacement is aimed at sunken bathroom structures, where pipelines can be freely laid within the lowered floor slab, with fewer restrictions on displacement. However, the prerequisite is that the building has this structure, and you can place the toilet wherever you want.

Wall-mounted Toilets

If you are afraid of blockages when modifying the ground pipes, you can opt for a wall-mounted toilet. The pipeline does not run along the ground, and the toilet's drainage is directly connected to the main vertical pipe. A sloped hole should be reserved, and a niche can be made above the water tank. However, this method is only suitable for modifications very close to the drainage pipe. Changing from floor drainage to wall drainage allows the pipeline to run along the wall, eliminating the need to raise the floor and making it easier to conceal the pipeline. However, it may require consent from the neighbor downstairs and redoing the waterproofing.

Raising the Floor Method

By constructing a base platform 180 to 200 millimeters high to embed the sewage pipe, this method is suitable for longer displacement distances and offers flexible layout options. However, it raises the floor, affecting aesthetics and convenience of use.

In addition, during displacement construction, attention should be paid to the slope and sealing of the drainage pipeline, and the waterproof layer should be redone. Improper operation may increase the risk of blockages or trigger neighborhood disputes. Before carrying out the displacement, it is necessary to fully evaluate the bathroom's drainage method (same-floor drainage or inter-floor drainage), displacement distance, and construction conditions.
