How to Clean a Bathroom Sink Drain Smell

If you’ve got a foul odor from your bathroom sink, the culprit is in the drain. Homeowners shouldn’t put up with the smell. You may be able to take care of it yourself without calling a professional. Here, you will learn how to clean a smell from the bathroom sink. The fix may be simple and easy to perform, but you won’t know until you try to tackle it yourself.

Why Does My Bathroom Sink Smell?

Usually, the source of a foul sink odor is bacteria. You (your kids or the homeowner before you) probably put food or grease down the drain, allowing bacteria to grow. Hair and soap scum buildup may be the cause, as well. Fortunately, the remedies we share here will work whether or not the cause is food or hair. If you smell something similar to the odor of rotten eggs, then you can be fairly sure that bacteria is to blame.

Try a Drain Cleaning Solution

The easiest way to get this task done is to try a drain cleaner, like Liquid Plumber or Drain-O. It’s an affordable solution, and it takes almost no effort. However, it may not get the job done. It’s worth a shot.

Snake the Drain

The most tried and true method for removing a bacteria-ridden clog is a snake tool (also referred to as a plumbing auger). Snake your way through the pipe and hook the clog so you can reel it out of the drain. It’s a good tool to have on hand for toilets, bathtubs, sinks…any kind of drain. You can spend a lot or a little on a snake tool, depending on the type (high-powered automatic vs. manual).

Boiling Water (No Go with Porcelain Sinks)

When the sink has slowly drained completely (despite the clog), This only works if your sink will still drain until it’s empty. Slowly pour the boiling water into the drain. Repeat until the sink drains as it should.

Plunge the Sink

Remove the sink hole cover and get to work with a standard plunger. A little water will help to create a tight seal.

Vinegar and Baking Soda Method

Start by pouring ¼ cup of baking soda into the drain. Follow that up by slowly pouring 1-¼ cup of white vinegar into the drain. Close the sink stopper and read a book for 20 minutes. Finish the job by pouring hot water down the drain. Repeat as necessary.

how to clean bathroom sink drain smell by replacing pipe

Replace U-Bend Pipe

If none of the other methods eliminate the odor, you may have to remove the portion of the sink drain pipe that is holding the smell. The U-bend pipe is designed to catch items you may have unintentionally put down the drain, like a wedding ring. Unfortunately, this means it also collects smells that may not disappear. Replace the pipe, and the problem is completely solved. This isn’t exactly a novice task, so you may want to turn to a professional plumber.
