Answer
To remove a sewer smell from your bathroom, try the following steps:
  1. Check the P-trap under the sink. If it has dried out, pour water down the drain to refill it and prevent sewer gases from entering12.
  2. Clean the sink overflow hole with a small bottle brush or a solution of half chlorine bleach and half water to remove any buildup of bacteria, soap scum, and hair that can cause odors2.
  3. Use a combination of baking soda and vinegar to clean drains naturally. Add 1 cup of baking soda to the drain, wait a few minutes, then follow with 2 cups of vinegar. Let it bubble for a couple minutes before flushing with hot water2.
  4. Check the wax ring seal around the toilet. If it is damaged, sewer gas can seep through. Replace the wax ring if needed2.
  5. Inspect the garbage disposal and run it with hot water and citrus peels or baking soda to remove odors2.
  6. Open windows to allow fresh air circulation and use charcoal bowls, scented odor eliminators, and vinegar sprays to absorb and neutralize odors2.
If the smell persists after trying these DIY methods, it may be time to call a professional plumber to inspect for more serious issues like a broken sewer line or bacterial buildup in the drains13. Sewer gas can be toxic, so it's important to address the source quickly.

  • 00:54 The sewer gas will come back into the room and you can actually hear it as well. So this is the shower in question I took off cover to the shower so you can actually see down into the pipe. Hope you can see that but there you can typically see water in there and it was completely dry and the shower is kind of nasty which may explain why nobody uses it but let me flush.
