Did you try scrubbing your toilet multiple times in different ways? But things didn’t work out as planned and here you are thinking, “Why does my toilet smell even after I clean it?”

Malfunction in any individual part of your bathroom can result in a sewer smell. Finding the exact source without proper knowledge is difficult. Keep reading as we boil down the reasons behind the foul odor and how to get rid of it.

Toilet Smells Even After Cleaning

Identify The Odor

Before going straight to the disease, we try to understand the symptoms, right? Let’s make the diagnosis easier by determining the type of smell first.

  • Sewer Smell From Toilet

The sewer-like smell comes due to the toilet piping problem and leakage in the pipe.

  • Toilet Smells Like Urine

If you smell anything like urine, you probably need a thorough cleaning. Did the Cleaning recently? Then check your wax seal.

  • Smell of Rotten Eggs or Sulfur in Toilet

Sometimes an odd stench like rotten egg or sulfur gas comes from harmful microorganisms seeping from the water.

  • Fishy Smell in Bathroom

A fishy smell in the bathroom is another unusual smell your nose may get. You have checked at everything in the toilet but overlooked your electric wires. Overheating can cause the plastics in the electric cables to burn and spread a ‘fishy’ scent.

Causes of Smelly Toilet

Several factors can produce the unpleasant scent you’re smelling. What are they? We’ve discussed them in this section:

1. Vent Pipe Malfunction – Clog or Improper Installation

Vent pipe is the extension of waste pipes. It vents the sewer gases away from the toilet and enables fresh air to come into the bathroom at the same time. Therefore, malfunction of the pipe can cause sewer odors. 

You can primarily notice this if your toilet is working fine but releasing sewer smell. The vent pipe can be clogged from outside elements like dry leaves or debris. Improper installation by an inexperienced plumber can make you suffer as well.

Toilet Clog

If the vent pipe is clogged, try snaking the drain. In case of improper installation or severe issues, contact a professional plumber to diagnose and fix it.

2. Broken Flange or Loose Bolts

The purpose of Flange and bolts is to keep the toilet firmly grounded. Your bathroom will jiggle if the bolts or flange is not tightly fit.

Check if your toilet is loose due to a broken flange. Good thing is that you can fix this issue all by yourself. Tighten the bolts or repair the flange, and your toilet will stop leaking the stench. However, if you are not familiar with these parts, call an expert plumber to take care of this for you.

3. Missing or Damaged Wax Seal

There is a waxed ring sealed under the base of your toilet. This seal protects your bathroom from leaking liquid or gas.

The wax seal gets damaged over time. You can understand it if your toilet is wobbling. If this is the case for you, sewer gas or water may seep through the crevice.

Some toilets don’t have to seal beneath them. Get a new wax seal at the base. Make sure to clean it first by removing the toilet itself. If you feel it is not your cup of tea, ask a professional to get the job done for you.

4. Evaporation of Water in the P-Trap

P-trap can be a common cause of smelly toilet water. This simple mechanism plays an important role in preventing the odor from slipping into your room.

Evaporation of Water in the P-Trap

P-trap is the curved pipe underneath the toilet bowl that traps water level to block sewer gas. However, the water level sometimes drops, thus making the trap ineffective.

This causes when you aren’t using the toilet much, or your flush can’t supply enough water. The fix is very simple as well. Flushing water a few times will solve the problem instantly.

5. Bacteria And Other Microorganisms in Toilet Bowl

Bacteria is one of the primary reasons for smelly toilet bowl. Research shows that your toilet bowl can contain up to 3.2 million bacteria per square inch.

These bacteria and other harmful microorganisms can spread disease as well as stinks in your room. Although regular cleaning prevents them from producing unbearable smells, there might be some hiding underneath the rim.

Make sure you clean the bacteria everywhere, including the hidden corners of your toilet, to get rid of this problem.

6. Dirty Toilet Cistern

The vent pipe, P-trap, wax seal, toilet bowl are all clean, and still no trace of that unpleasant smell? Did you check your toilet cistern?

Most of us overlook the toilet tank while cleaning the rest regularly. Sludge may build up in the tank without a long-time cleaning. If you haven’t cleaned your toilet cistern recently, take a look inside and sniff. You’ll notice if the smell gets stronger there. 

The cleaning process is easy. Get a scrubber and cleaning agent. Scrub it, and you’re all done!

7. Cracked Toilet

Sometimes the toilet itself may be the culprit. Check if your toilet is cracked or damaged. Broken toilet is a severe problem that requires professional attention. 

If you checked every factor and still couldn’t understand where the problem is, there may be some more complicated plumbing issues. Get help from a trusted professional plumber for the repair or replacement of your toilet.
