How do we unclog your bathroom drain?

- Chemical-free solutions: works great for minor blockages with biodegradable enzymes for environmental protection
- Manual removalIf the siphon is accessible, we remove the dirt manually, ideal for blockages under the sink.

Frequently asked questions
What are the most common causes of a clogged bathroom drain?
A clogged bathroom drain is usually caused by a buildup of hair, soap residue, toothpaste, or skin oils. These materials accumulate over time in the trap, shower drain, or pipework, causing water to drain more and more slowly, eventually becoming blocked. Regularly cleaning the drain and using a strainer can prevent many problems, but some blockages are unavoidable, especially if the pipework is older.
Besides hair and soap scum, items like cotton swabs, razors, or small shower products can also accidentally end up in the drain. This creates an additional challenge when unclogging. If you notice that multiple drains in your home are draining slowly at the same time, there may be a deeper blockage in the main sewer. In that case, it's best to contact us immediately to prevent the problem from getting worse. See our tips on quickly resolve a sanitary blockage for more insight.
How can I unclog my bathroom drain myself without causing damage?
If you have a blockage in your bathroom drain, you can first try manually clearing the drain or trap. Unscrew the trap, remove any hair or soap residue, and rinse thoroughly with warm water. If necessary, use a plunger (plunger) to create air pressure and dislodge the blockage. Avoid harsh chemical drain cleaners; they can damage the pipes and are harmful to the environment and your health.
If the plunger doesn't work, try hot water mixed with baking soda. This helps loosen grease and soap residue. If the problem persists or the blockage keeps recurring, it's wise to seek professional help to prevent damage to your drain system. Ontstoppen.nl Works with professional equipment and offers an 8-week warranty. Want to know more about safe unblocking? Read our advice on unclogging drain including call-out charges.

Sometimes the blockage is too deep in the pipework to be cleared with household remedies.

How do you prevent your bathroom drain from becoming clogged again in the future?
To prevent your bathroom drain from clogging again, regular maintenance is essential. Remove hair from the shower drain immediately and use a strainer to prevent larger particles from going down the drain. Rinse occasionally with hot water and baking soda to loosen accumulated grease and soap scum. Check the trap under the sink once a month and clean it thoroughly.
Avoid flushing foreign objects such as wipes or sanitary towels down the drain. Also, be careful with the use of harsh household products, as these can damage the pipes. If blockages persist despite these measures, there may be a structural problem in the plumbing. In such a case, we recommend a professional inspection and, if necessary, preventative maintenance to ensure your drain stays clean and you can enjoy a well-functioning bathroom for longer.
