Reasons Behind Slow Bathroom Drains

Does your shower end with you standing in a puddle of soapy water that takes 10 minutes to drain? Then you are facing slow bathroom drains. They are annoying, and sometimes, they can be downright frustrating. There are many reasons why this occurs, but the most common culprit is a clog. Here are some of the top reasons for slow bathroom drains, including various types of clogs.


While showering, a lot of your hair gets washed down the drain. Over time, hair can get accumulated in the drainpipe, causing a clog that ends up restricting the flow of water. An easy way to unclog your drain by using the old fashioned plunger. If that does not work, you can also use a thick steel wire with a hook at one end to pull the hair out.

Shaving Cream

Similarly, if you shave a lot, then the shaving cream and beard trimming can get washed down the drain. Both together can form sticky cement that clogs the drain. The best way to fix this is by using a thick steel wire as mentioned above, or by pouring down a mixture of vinegar and soda to dissolve the cement. Avoid using chemical drain cleaners as they can damage your pipes, especially if they are PVC.

Soap Scum

Some soaps are also notorious for scum buildup within the drain. These clogs can be annoying and often persistent. To clear these clogs, you should use a potent mixture of vinegar and baking soda, or boiling water to wash it down the drain. Sadly, if this issue is persistent, then you may have to contact a plumber as there might be an issue with your bathroom drain’s structure itself. 

Offset Pipes

The soil under and around your house is never stationary, and it keeps moving a few centimetres here and there every year. This happens due to the fluctuating temperatures and rains. Some of these movements can end up forcing your bathroom drain pipe offset, restricting the flow of water. The only way to fix this is by contacting a professional plumber to install sturdier drain pipes.

Root Intrusion

The worst enemy of your bathroom drains is probably tree roots. If your bathroom is on the ground floor or near a tree, there is a high chance a tree root might intrude in and cause a clog. Unfortunately, fixing such clogs is difficult, and must be left to professionals as it requires specialized equipment.

If slow bathroom drains are persistent even after you clean the drains or suspect offset pipes or root intrusion, you should contact a professional drainage service provider soon. Ignoring these issues can end up costing you a lot of money in repairs and replacements.
