How to Remove Sewer Smell from Bathroom

Dealing with a sewer smell in your bathroom can be unpleasant and frustrating. Understanding the source of the problem is the first step in getting rid of the smell. There may be several possible causes to consider.

In some cases, sewer line issues may be the underlying problem. Damaged or cracked sewer lines can allow sewer gases to enter your bathroom, resulting in a persistent smell.

Common Causes of Sewer Smell in the Bathroom

In this section, we’ll dive into the leading culprits that may be responsible for that foul odor. 

Dry P-Trap

A dry P-trap can be the cause of sewer smell in the bathroom. The P-trap, a curved pipe under the sink or shower that traps water, is what creates a barrier to prevent sewer gases from entering your bathroom. However, if the P-trap becomes dry, this barrier is broken, allowing the sewer smell to escape.

Blocked or Clogged Drains

Blocked or clogged drains can be a major cause of sewer smell in the bathroom. When drains become blocked or clogged, water and waste can accumulate and create a foul odor. It is important to address this issue promptly to prevent further problems.

Sewer Line Issues

Debris, grease, or foreign objects can accumulate and block the sewer line. This blockage can hinder proper drainage and result in sewage backup, creating a strong odor in the bathroom.

Vent pipes are installed to release sewer gases outside the building. If these vent pipes become blocked or damaged, the gases may get trapped and find their way back into the bathroom, causing the unpleasant smell.

In this section, we’ve got all the methods you need to eliminate that unpleasant odor. Say goodbye to that sewer smell and say hello to a fresh and inviting bathroom.

Clean the P-Trap

  • Using a wrench, carefully unscrew the slip nuts located at both ends of the P-Trap. It’s important to be prepared for water to drain out as you do this.
  • Once the slip nuts are loosened, remove the P-Trap and thoroughly inspect it for any clogs, such as hair or debris. Use a cleaning brush and warm, soapy water to clean the trap.
  • Next, flush water through the P-Trap to ensure it is completely clear of any blockages.

It is highly recommended to regularly clean the P-Trap every few months. This will help prevent clogs and eliminate any potential foul odors that may arise in your bathroom.

Check for Sewer Line Problems

  • Listen for gurgling or bubbling sounds coming from your drains. This could be a sign of a blockage or clog in the sewer line.
  • If you have access to your sewer line, such as through a cleanout, check for any blockages or obstructions. Checking for sewer line problems becomes crucial at this point. You can use a plumber’s snake or a high-pressure water jet to clear any clogs.
  • If you suspect a more significant issue with your sewer line, such as a break or collapse, it is recommended to call a professional plumber to perform a camera inspection. This will provide a clear view of the inside of the sewer line and help identify any problems.

Use Homemade Remedies

Vinegar and baking soda: Create a mixture of equal parts vinegar and baking soda. Pour it down the drain and let it sit for about 30 minutes. After that, flush the drain with hot water to remove the sewer smell.

Lemon juice and hot water: Squeeze fresh lemon juice into a bowl and pour it down the drain. Follow it up with hot water to eliminate the odor. Lemons have natural deodorizing properties that can help get rid of unpleasant smells.

Bleach solution: Mix one part bleach with ten parts water. Pour the solution down the drain and let it sit for a few minutes. Rinse it off with plenty of water to remove any residual smell. Be cautious when using bleach, as it can be harmful, and ensure proper ventilation while using it.

Activated charcoal: Place activated charcoal in a small mesh bag and hang it near the source of the sewer smell. Activated charcoal is known for its ability to absorb odors and can effectively neutralize the smell in your bathroom.

Preventing Sewer Smell through Proper Ventilation

  • In order to ensure proper ventilation and eliminate sewer smell from the bathroom, it is important to install a bathroom exhaust fan. This fan will effectively remove odors and moisture from the air, preventing the buildup of unpleasant sewer smell. It is crucial to choose a fan that is appropriately sized for the bathroom to ensure efficient air circulation.
  • Keeping windows open during and after using the bathroom can vent out any unpleasant smells, allowing fresh air to circulate and replace the stagnant air.
  • Maintaining the cleanliness of the bathroom fan and vents is a key aspect of ensuring proper ventilation. Over time, dust and debris can accumulate in these components, hindering their effectiveness. Regularly cleaning and maintaining the fan and vents will ensure efficient ventilation and help prevent sewer smell.
  • If installing an exhaust fan is not feasible, a window vent can serve as an alternative solution for improving bathroom ventilation. A window vent allows the flow of air out of the bathroom, enhancing the overall ventilation process.
