Why my Shower Drain/Shower Tray Blocked?

The combination of hair, soap scum, hard water scale, dead skin cells, and unexpected intruders such as toothbrushes or false eyelashes can wreak havoc on your drainage system. Aside from the inconvenience of slow drainage, the consequences of a neglected blockage can escalate to unpleasant odors and, in severe cases, bathroom flooding due to water seeping through shower joints.

Why my Shower Drain/Shower Tray Blocked?


Long strands of hair easily intertwine, forming dense clumps. Hair binds with soap and other debris, gradually creating a mesh that restricts water flow.

Soap Scum

Soap scum is a complex mixture resulting from the reaction between soap and hard water minerals. Soap contains fatty acids, which, when combined with calcium and magnesium ions in hard water, undergo a chemical process called saponification. This process leads to the formation of insoluble soap scum—sticky and adhesive in nature.

Soap Scum blocked shower drain

Hard Water

Hard water is characterized by a high mineral content, primarily calcium and magnesium ions. When hard water flows through pipes, these minerals can precipitate and form deposits. Over time, these deposits accumulate, creating a hardened layer known as limescale. Limescale build-up not only reduces the internal diameter of the pipe but also provides a rough surface for other particles, including soap scum and hair, to adhere to.

Dead Skin Cells

Microscopic skin cell particles. Millions of skin cells shed during showers, contributing to the accumulation of fine particles that can create blockages.

Dead Skin Cells Blocked shower drain


Many toothpaste formulations contain thickening agents, such as hydrated silica or calcium carbonate, which can settle and solidify in the drainage system. Additionally, the combination of toothpaste residues with hair and other debris can create a cohesive mass that adheres to pipe walls, impeding the smooth flow of water.

False Eyelash/Double Eyelid Sticker

These cosmetic items are prone to clogging due to their sticky nature, which is not easily broken down by hot water. The sticky parts can adhere to other contaminants in the pipes, causing blockages over time.

Creams/Cream Masks:

Residue from skincare products often contains emollients, oils, and other compounds. These residues can combine with other debris, forming a compound clog. Additionally, certain ingredients may solidify over time, exacerbating the blockage.

How do I know if my shower drain is clogged?

Common indicators include slow drainage or water not draining at all after a shower. If you find yourself standing in a pool of water after shower that doesn’t recede as quickly as usual, it’s a clear sign of a potential blockage. Additionally, an unpleasant smell emanating from the drain, caused by accumulated debris, may accompany the issue. In more severe cases, water seeping through shower joints can lead to bathroom flooding. Stay vigilant for these signs to address potential blockages promptly.

How to Prevent Hair-Related Drain Blocks?

Hair is a common culprit when it comes to shower drain blockages, but proactive measures can keep clogs at bay. Here’s how to focus on preventing hair-related drain issues:

Use a Drain Cover

  • Recognizing that hair easily finds its way into drains, invest in a reliable drain cover.
  • A drain cover acts as a protective barrier, capturing hair before it enters the drain.
  • Regularly clean the drain cover to ensure optimal performance and prevent buildup.

Use a Hairnet

  • Acknowledge the tendency of hair to contribute to clogs, especially for those with longer hair.
  • Incorporate the use of a hairnet during showers to contain loose strands.
  • Dispose of collected hair appropriately after each use to prevent it from reaching the drain.

How to prevent hard water causing Shower Drain Blocked?

Hard water, characterized by high levels of calcium and magnesium minerals, poses a persistent threat to shower drains, often leading to gradual blockages. However, Use a thermostatic shower mixer can go beyond temperature control, playing a crucial role in preventing issues stemming from hard water.

  • Thermostatic Shower mixer reduces the risk of hot water evaporating. If leaving mineral deposits behind, it can contribute to blockages.
  • Maintaining a consistent temperature helps mitigate the negative effects of hard water.
  • Thermostatic shower mixer provides precise control over water temperature.
