Smells From Your Shower Drain

One of the most popular causes of a sewage odor is not the toilet— if you smell a nasty drain odor in your bath room, inspect the drain in your shower. A stinky shower drain is normally caused by one of two things: biofilm buildup or an issue with your P-trap.

1. Biofilm Accumulation

When we shower, we use a variety of items. Body oils, conditioner, hair shampoo, soap, and shaving cream, together with natural waste such as skin cells and hair, are washed down the drain.


All these materials regularly build along the P-trap and vertical pipes that run beneath your shower gradually. This buildup is called a biofilm.


Biofilm starts to develop a sewage-like odor as it grows due to germs and disintegrating waste. Bacteria produce a sticky material that enables them to hold on to the side of your pipes, making them tough to remove without the use of unique tools.


Ultimately, these sewage smells fill the whole bathroom, not simply the shower or tub.


How to Eliminate the Problem: Normally, removing biofilm and the smells it causes in shower drain pipes is an easy task that does not need the services of a plumbing professional.


Here’s how to remove the smells from your bathroom, clear the material that is feeding the germs in the drain. Baking soda, boiling water, and white distilled vinegar can be mixed to make an all-natural cleaner.

In order to remove biofilm from your pipes, follow the steps listed below:

  • Eliminate the shower drain using a screwdriver.
  • Next, bring 5 to 10 quarts of water to a boil.
  • Allow the water to cool to 150 ° F before slowly pouring it down the shower drain.
  • One cup of white distilled vinegar ought to be added in after the water.
  • Pour half a cup of baking soda down the drain quickly after adding the vinegar.
  • Finally, use a drain brush to clean up any remaining junk in the drain.

But, if the drain gas odor in the bathroom continues after cleaning the shower drain, contact a professional plumber to check your water supply.

2. Dry P-Trap

A dry P-trap is another common source of drain gas smells in the home. A P-trap is a U-shaped pipe that traps and holds water. A P-trap needs to hold plenty of water to keep sewage gases and smells from sneaking up your drain when it’s working appropriately.


In case you don’t use your shower much, the water might have simply dried in the P-trap. Yet, if you regularly use your shower and still see a sewage odor coming from your drain, this might show a more major problem.


Your P-trap might leak and stop holding water.


How to Fix the Issue: Depending upon the reason for the dryness, fixing a dry P-trap might be easy or difficult.


Some home-owners might not use the shower as frequently, therefore, the water might frequently dry in the plumbing.


Turn on your shower and let the water run for a couple of minutes to refill the P-trap, and you’ll be done in no time at all. The water needs to be enough to avoid and fill the p-trap sewage gases from leaking into your bathroom.

If the odor continues after running water through all drains, it is more than likely due to an old or leaky P-trap. Contact a professional plumber to inspect and replace your P-trap for the very best results.

Smells From Your Toilet

A bad-smelling toilet might normally be fixed with a fast clean, a couple of flushes, and some air freshener. No matter how many times you clean your bathroom, some smells will stay.


There could be several reasons your bathroom smells like a sewer. The most common include an improperly installed or cut vent pipe, a broken or loose seal, and a dripping toilet.

1. Improperly Set Up or Cut Vent Pipeline

If the walls near your toilet have a constant sewage odor, it could be due to an improperly positioned or cut vent pipe.


The vent pipe helps in the control of air pressure in your house’s plumbing system. Vent pipes help drive smells outside your home, keeping them from entering your house or bath room.

How to resolve the problem: A skilled plumbing technician can help you in repairing any vent pipe concerns. A specialist plumbing contractor can easily diagnose the problem and reinstall a brand-new pipe in cases of malfunctioning installation.

Often a vent pipe will form holes, enabling smells to enter your house. A plumbing technician will use a smoke device to fill the pipe in order to find any holes.


The smoke device is utilized to fill the pipe in order to find any holes. When the smoke starts to appear, they will locate the source of the leak and repair the pipe.

2. Damaged or Loose Seal

A cracked or loose seal might be the reason for sewage smells coming from your toilet. The toilet connects to the drain through 2 different seals. And, if these seals are loose, cracked, or incorrectly positioned, drain gases might enter your bathroom.


An indication of a broken seal is if the toilet bowl does not fill normally. If a seal loses water and sewage, a strong odor might not be triggered by sewage gases.


The wax ring that seals the toilet drain and prevents water from leaking can also be the reason for a dripping toilet. If the toilet bowl is loose, it might damage the wax ring, enabling sewage to permeate out and produce foul odors.


Your toilet might also be cracked, broken, or otherwise damaged. For example, it might have divided around the bolts that hold it to the floor. Any little space can enable sewage gas to enter your bathroom.


How to repair the problem: If the concern is a damaged or loose seal, a fresh coating of caulk is frequently enough to deal with the concern.


Caulk the seals on your toilet as well as the bolt holes that hold it to the ground. Check your toilet bowl to see if it is unstable or loose; if so, the wax ring might have been damaged.

To repair it, replace the toilet ring with a brand-new one. If the toilet appears to be broken, contact a professional plumbing professional to get it repaired or have it replaced with a brand-new one.

Smells From Your Sink

Your bath room sink might produce a sulfur-like odor at times that can be caused by a variety of things, consisting of a dry P-trap, similar to a shower drain. The buildup in the overflow, on the other hand, is a typical reason for smells.

1. Accumulation in the Overflow

See if your sink has an overflow mechanism, and if so, look for sewage smells coming from it. Different sinks have a hole near the top that works as a water outlet, avoiding excess water from gushing into the bathroom.


Your sink, like everything near water, might easily build up dirt and mildew, especially in the overflow area.


How to repair the concerns: Thankfully, cleaning the overflow is an easy task. Water, bleach, and a little bottle brush is all you require.


  • Scrub the interior of the overflow area with a little bottle brush to remove any debris.
  • Next, mix half water and half chlorine bleach in a solution.
  • Apply the solution to the overflow area with the bottle brush to remove any remaining smells or germs.


Call a professional plumber to check your sink if the smells continue in spite of thorough cleansing.

Smells From Your Washing Appliance

Bathrooms are most likely the first place people look when a house smells like sewage. If you can’t identify the source of the odor in your bathroom– look into your washing unit– the problem could be concealing in your laundry room.


The most common reasons a washing unit smells like sewage are incorrectly placed P-traps, drain clogs or vent pipe clog.

1. Improperly Set Up P-Trap

P-traps are not only required in the bathroom; they are also required in washing machines. Modern washing machines, on the other hand, featured a flexible drain hose pipe, unlike a lot of bathroom pipes.


The wastewater from a washing unit is sent out by this flexible hose into the drain box pipe, which is linked to the P-trap. It is commonly not set up appropriately since the hose is flexible.


The hose might have been put too far into the drain box, stopping the P-trap from working. As a result, smells might enter your household.


To solve this concern: Attempt taking the washing unit drain hose out of the drain box. Stop when the hose is about 8 inches deep in the pipeline; this will enable the P-trap to operate appropriately, keeping sewage gases from seeping into the space.

2. Drain Obstructions

Obstructions in the drain line are another frequent reason for a bad-smelling washing unit. A block in the drain line will cause an accumulation of organic matter such as hair and soap.


Bacteria will grow generating a foul odor similar to that of sewage. If left neglected, an obstruction will continue to expand in size and produce more visible smells.

How to deal with the concern: Thankfully, a blocked drain is easy to deal with. Clear any clogs in the drain line with a drain snake. Call an expert plumbing company to check your drain and washing unit if the blockage would not budge.

3. Vent Pipeline Clogs

Washing machines, like your bathroom plumbing, require vent pipes. To prevent sewage gases from entering your property, all drain systems in your house need to be appropriately vented.


How to Solve the Problem: Gain access to your roof to look for clogs in your vent pipes. Bring a flashlight with you and shine it into the vent pipes. Look for any blockages, such as bird nests or other junk. Attempt to loosen up or remove them with a snake or another long tool.

Smells From Your Water

1. Bacteria in Your Water Heater

The trouble is most likely with your water heating system if the odor is only detected when using hot water.


Bacterial nests can form in a water heater if the temperature is too low or if it is turned off for an extended quantity of time. The germs are not harmful to people, so your health is not threatened.

If your water smells nasty, regardless of whether it’s cold or hot, the root of the problem could be your water system. A strong sulfur odor is produced in your house by extremely strong levels of hydrogen sulfide.


Although hydrogen sulfide can be hazardous in high amounts, it is normally simple to detect before it reaches hazardous levels.


Human beings can detect hydrogen sulfide at amounts as low as.5 parts per million (PPM)– values less than 1 PPM produce a moldy odor, and levels in between 1 and 2 PPM produce an odor similar to rotten eggs.


How to resolve the problem: If you presume your water system has hydrogen sulfide, contact a local water screening laboratory to get it evaluated for pollutants.
