When it comes to installing drainage pipes in a building, there are several options available, including installing the pipes below the tiles or hanging the pipes from the ceiling. While each installation method has its own advantages and disadvantages, in this blog post, we will focus on the differences between hanged drainage pipes and those installed under the tiles.

Hanged Drainage Pipes.

In this method, the drainage pipes are installed below the ceiling or suspended from the ceiling using hangers or brackets. This method is commonly used in buildings where the ceiling height is high. This method requires careful planning to ensure that the pipes are properly supported and sloped to allow for proper drainage.

There are several advantages of hanging drainage pipes:

  1. Easy access for maintenance: Hanging drainage pipes make it easier to access the pipes for maintenance and repair work. Since the pipes are installed below the ceiling, there is no need to remove tiles or flooring to access the pipes.
  2. Flexibility in installation: Hanging drainage pipes offer flexibility in installation since they can be installed in any location below the ceiling, regardless of the location of walls or other structural elements.
  3. Reduced risk of leaks: Hanging drainage pipes can reduce the risk of leaks since they are not subject to the same pressure as pipes installed within walls. This can reduce the risk of water damage and costly repairs.

While hanging drainage pipes can offer several advantages, there are also some potential disadvantages to consider:

  1. Ceiling height limitations: Hanging drainage pipes require adequate ceiling height to be installed properly. In buildings with low ceilings or limited space, hanging pipes may not be possible.
  2. Structural considerations: Hanging drainage pipes require proper support and may need to be secured to structural elements such as joists or beams. This can add complexity to the installation process and increase the risk of damage to the ceiling or surrounding structures, especially when we have a ripped slab or a post tension one.
  3. Cost: Hanging drainage pipes can be more expensive to install than pipes installed within walls. The cost of the materials, labor, and additional support structures must be considered.

Under-Tile Drainage Pipes

This a considered the traditional way of installing drainage pipes, in this method, the drainage pipes are installed under the floor tiles. This method is commonly used in buildings with a modern and contemporary design, where exposed pipes are not desirable while having a low ceiling height, and there is no space for suspended pipes.

There are several advantages to installing drainage pipes under the tiles, including:

  1. Space-saving: By embedding the pipes in the floor, valuable floor space can be saved, making this installation method ideal for buildings with limited space.
  2. Noise reduction: Installing pipes under tiles can reduce noise and vibration, as the pipes are not in direct contact with the walls or other structures.
  3. Cost: The cost of adopting this method is lower, as the materials costs are lower, and the supporting structure is not used in compare with the hanging type, and finally this will impact . the labor cost and make it lower significantly.

After discussing the pros, lets have a look at the cons:

  1. Limited access to repair or replace: In some cases, repairing or replacing pipes installed under the tiles may require removing and replacing the tiles or flooring, which can be expensive and time-consuming.
  2. Increases risk of leaks: Since these pipes are subject to a higher pressure (from the tiles and above surface) than the hanged one . This can increase the risk of water damage and costly repairs.
  3. Increase deadload on the slab: as this method shall consider an extra backfilling to cover the pipes, and this will put an extra weight on the slab.


The decision between hanged drainage pipes and those installed under the tiles will depend on the specific needs and requirements of a building.

Both installation methods offer their own advantages and disadvantages, and the designer can help determine the best installation method for a particular building.

Regardless of the installation method chosen, it is important to consider the workmanship quality and the material chosen, to ensure the effectiveness of the system, as the plumping system is considered an essential part of the building’s soul.
