There are several smells that might be encountered. You might have your toilet smelling like sewage, urine, rotten eggs, and more. This section covers the more common odors and elimination methods.


A toilet that smells like sewage is one of the common problems. Several things might cause this.


Numerous things can cause your toilet to smell like sewage. However, one of the major issues is a problem with the P-trap.

This P-trap is a U-shaped pipe designed to hold some water to prevent sewer gases from coming up from the toilet and into the air. If the P-trap is dry or has some other problem, then the gases from the sewer might escape your toilet.

Dealing with this problem will require that you tackle each of the causes.

If the issue is because of the toilet seat, you have to clean it yourself. It might be gross, but you don’t have a choice but to clean it. To get rid of this particular problem, unscrew the lid or seat. After removing it, then use a toilet cleaner or soap to clean it thoroughly. Reviews have revealed that the Scrubbing Bubbles toilet bowl cleaning starter kit comes with all you need to clean your toilet and remove any bad smells completely. Do this at least twice per year, and you might not have to worry about this problem anymore.

If the cause is the floor, then the solution is relatively easy. The smell is likely because of people peeing on the floor. Therefore, discourage this habit – especially if you have boys. Cleaning the toilet floor will also eliminate the smell. You can use the popular Clorox Toilet Wand cleaning system to help with cleaning and eliminating smells.

If you have cleaned the floor and the toilet seat but still have a urine smell, then you might have to look under the toilet bowl. The smell might be due to a leaking seal under the toilet bowl. If this is the problem, you can get a plumber to quickly look at it and help you make the required repairs.

Rotten eggs or sulfur

Another common stink is the stink of rotten eggs or sulfur. If this is what you experience, don’t fret since things can be done to get rid of the stink. Before we consider the solution, let’s first see what might be responsible for the smell.


Sulfur or rotten egg smell is usually a result of bacteria in the toilet. Finding the exact cause of Sulphur smell can be difficult. That is why most plumbers recommend that you carry out a test to know where exactly the smell is coming from.

The test is pretty simple. First, fill a glass with water from the water that smells like Sulphur. Then fill another glass with water from another tap. Smell to determine whether the two smell like Sulphur. If both water glasses have a Sulphur smell, then the bacteria is likely in the water from all pipes in the home.

On the other hand, if the smell comes from just one glass of water, only one pipe is contaminated.

How to deal

Solving this problem is relatively easy. If it is just a pipe with the smell, you can solve it by replacing the drains. Another thing that can be done to deal with this is to apply a disinfectant to remove the smell.
