One of the most prevalent causes of sewer odor in your bathroom is a dry P-trap. A P-trap is a U-shaped conduit that runs beneath the sink or drains. It’s utilized to keep sewage odors out of the bathroom by trapping water behind the drain. If you don’t use your bathroom sinks on a regular basis, the water in the P-trap may dry out, allowing sewage gases to enter your bathroom easily.

It’s easy to solve this issue. Simply run some water through the sink for a minute or two to solve the problem. You can also pour a little baking soda down the drains to prevent them from clogging.

2. Clogs in the shower drain

Clogs in your shower drains can be caused by soap shards, shower gel, dead skin, hair, and other debris. If you notice a sewage odor in your bathroom, as well as small flooding when showering, you may have a plugged shower drain.

This problem has a simple solution that you may implement on your own. It can, however, be a shambles. You can hire an expert to fix it if you don’t want to get your hands filthy. This is what you must do if you decide to do it yourself. Remove the shower drain cover first. Pour a constant stream of vinegar and hot water down the drain, then add 1 cup of baking soda and let it sit for two or more hours.

This procedure should be enough to release the deposits. After that, use a drain brush to remove any solid stuff that may have become stuck in the drain before running clean water for a few minutes. You’re done once you’ve screwed the drain cover into place.

3. Broken toilet

Your toilet may become damaged over time due to wear and tear, and this could be the cause of sewage gas escaping into your bathroom. A good example is when the wax barrier at the base of your toilet loosens, allowing sewage gas to flow into your bathroom through microscopic cracks.

Small cracks in your toilet bowl can also create water leaks, causing the water level in your toilet’s P-trap to drop. Low water levels in the P-trap may allow sewage gases to enter your bathroom, resulting in a foul odor. If you’re having trouble with something like this, it’s advisable to get a professional to help you.

4. Vent pipes that are broken, clogged or inappropriately installed

The vent pipe serves as a breather for your sewer system. When it becomes clogged, sewer gases can back up into the sinks and toilet, causing sewage odors in your bathroom. As sewage gas forces its way into the bathroom, you may hear a bubbling sound coming from the toilet or drain.

Poor installation or obstructions produced by solid objects that find their way into the vents are two possible reasons for blocked vent pipes. To fix the problem, look for any blockages in the vent and remove them if possible, or hire a professional.

5. Build-up of bacteria

The sewer system is an ideal breeding ground for hazardous bacteria that can enter your bathroom and multiply under the toilet bowl, eventually causing foul odors. This is especially true during the summer when germs multiply at a high rate.

Bleach can be a useful tool for preventing bacterial growth. However, swishing bleach around the toilet bowl isn’t going to cut it. It is feasible to eliminate the threat by adding bleach to the flush tank and flushing the toilet a few times.

6. Septic tank in its entirety

If your drainage system is connected to a septic tank in your complex and you detect a sewerage odor in your bathroom, your septic tank may be full. When your septic tank is full, the sewage smell isn’t the only thing you’ll notice. The toilet and drains may begin to make bubbling sounds, and your toilet may become slow.

The remedy to a clogged septic tank is simple: drain it. It’s a good idea to check your septic tank levels on a frequent basis to avoid being caught off guard by a full tank.

7. Backups from sewer

If you smell sewer after a hard downpour, it could be a sign of sewer blockage. Excess runoff water piles strain on the city’s sewer infrastructure during heavy rains, producing a sewer overflow into individual lines. Sewage may back up into dwellings as a result of the backflow. When the pressure is low, the sewerage may not flow back into the house, but it may push the sewage gases trapped in your lines back into the house, which would explain the sewer odor.

In this circumstance, you have little control over the situation. It’s possible that waiting it out is your only option. Installing a backflow valve in your sewer pipes, on the other hand, can assist prevent sewer water from backing up into your home.

One of the holiest areas of the house is the bathroom. However, a sewage odor can detract from the calm. A sewage odor in your bathroom is not only dangerous to your health, but it may also be embarrassing. As a result, you must address the problem right away.
