What does it mean to have a bathtub drain clogged?

How does a blockage occur in the bathtub drain?
Your bathtub drain has to deal with more than you might realize. Hair, soap, skin oils, bath foam residue, and sometimes even small objects form a stubborn buildup in the trap or pipes. Over time, this residue builds up, as described on Wikipedia and in the databases of the Dutch Water Boards, creating a bottleneck that barely allows water to flow through.
- Hair buildup: Hair quickly tangles with soap and forms plugs that literally block the flow of water.
- Soap and lime deposits: Especially in regions with hard water, limescale quickly forms, which together with soap residue, forms a hard layer inside the pipe.
- Incorrect installation: If the drain is installed incorrectly, sand, construction waste, and other debris can quickly enter your pipes, increasing the risk of blockages.
- Pipes with bends: Older houses often have less favorable pipe routes with many bends, where blockages can more easily become trapped.

- Diagnosis: We use inspection cameras to determine exactly where the blockage is located.
- Targeted approach: Depending on the severity, we use a spring machine or high pressure to restore flow.
- Complete cleaning: The entire drainage route from siphon to downpipe is completely flushed with professional HD equipment.
- Drain testing: We check that the water drains smoothly before we finish.

Types of bath drain clogs and their causes
Not every bathtub is the same, and drainage also presents various challenges. If you consider rim-integrated models from Villeroy & Boch, Duravit, or Xenz, you'll often encounter different types of pipes and siphons than with freestanding bathtubs. An acrylic bathtub also differs in its sensitivity to aggressive drain cleaners compared to a steel model.
- Partial blockage: Water still drains away partly, but drips slowly, often caused by hair and soap.
- Complete blockage: Nothing flows anymore. The causes are usually deep blockages or an incorrectly installed siphon.
- Recurring blockage: Does the problem keep recurring despite all attempts to resolve it? Often, there's an underlying pipe rupture or subsidence.
- Odor nuisance: A foul sewer smell around your bathtub is often caused by a malfunctioning odor trap or a leak in the pipes.
