Why Does My Toilet Smell like Urine?

Despite regular cleaning, the toilet still sometimes smells like urine. We know how disappointed this makes you. Wondering why this smell persists and how to remove it for good?

So, “Why does my toilet smell like urine?”

The biggest reason why the toilet smells like urine is that the plumbing gets clogged. The clog could be in either the toilet drain or the vent pipe. Corrosion to the wax sealing or a broken P trap is two further possibilities. 

These are only a few examples. In this post, we will discuss further reasons for this problem as well as appropriate solutions. So come along, everybody!

8 Reasons Why Toilet Smells like Urine

After significant analysis and trial and error, we identified eight primary reasons of these issues. Let’s dig a little deeper into these.

Reason # 1 Toilet Drain is Clogged

Toilet Drain

Even though your toilet flushes normally, there could be a little clog in the line. If this clog is not removed, it will begin to stink. To clear the clog, the drain needs to be snaked.

Use a wrench or screwdriver to snake the drain. To remove the slide nuts on both sides of the P-trap, do the following. Once they’re free, use some force to remove the P-trap. After you’ve opened the drain, use an auger to loosen up and release some of the clogs.

Don’t have any augers to snake the drain? Here are a few of our suggestions.

The auger should be small enough to clean the p-trap and move around a little. Nowadays, thanks to the internet it’s easy to get any size you want.

Reason # 2 Clogged Plumbing Vent Pipe

Toilet Vent Pipe

Waste from the toilet is sent to the sewer after flushing. However, it is not uncommon for a disagreeable sewage odor to linger. However, if the odor remains or becomes stronger than normal, the vent pipe is most likely clogged.

A tube flowing through the ceiling is connected to your drainage system. The pipe eliminates or ventilates sewer odors. This enables air into the system, which permits sewage fluid to drain properly.

Sewage gasses will be unable to escape if the vent becomes clogged. This would have the ability to stink up your bathroom.

Examine the vent to determine if anything is obstructing it. If this seems to be a block, we recommend that you contact a professional to manually remove it.

Reason # 3 Wax Sealing Ring on the Toilet is Damaged

Toilet Wax Ring

The wax sealant ring beneath the toilet is prone towards becoming loosened over time. When this happens, sewer gas may leak through the seams and stink up your toilet.

If your toilet wiggles or shakes, it means your wax sealing ring is loose and has to be changed.

Reason # 4 Poor Ventilation


Given that we use the toilet on a regular basis, the odor of waste might remain in the air. Especially if there isn’t any ventilation to keep the air pure. This is likely if the exhaust fan is turned off or the toilet window is infrequently opened.

So make sure there’s enough ventilation for the odor to dissipate. Use the exhaust fans in the bathroom. If there’s none, at least keep the windows open.

Reason # 5 P Trap Seal Broken


One of the most common reasons for this unpleasant odor is the issue with the p-trap. The p-trap is a tube in the form of a U. It contains a little quantity of water that serves as a preventive barrier against sewage gases.

Sometimes, the p-trap allows these gases to escape via a leak, or a broken seal. If the p-trap seal gets broken, then call a plumber.

Reason # 6 Urine on the toilet seat

Urine on the toilet seat

Urine is very often discovered under the tank cover and on the toilet seat. When urinating, some people may not always find their mark. This results in some pee in the crevices of the toilet seat cover.

Even after cleaning the bathroom multiple times, this pee will pile up and generate the pee odor in the bathroom. This really is down to a lack of focus on areas other than the toilet.

So make sure to pay attention to the toilet seats if they have been peed on.

Reason # 7 Urine on the Floor

Urine on the Floor

Whenever anyone misses their target, pee can readily make its way to the restroom floor. This is particularly true if you have young sons. This kind of urinary odor is rather simple to deal with.
Small children also tend to target the bathroom walls. This makes it necessary to protect the walls against urine.
