If your toilet smells like urine even after cleaning, you’re not alone. This is one of the most common bathroom odor problems, and it can be both embarrassing and frustrating. A lingering urine smell makes your bathroom feel dirty, even when it isn’t. The good news? Once you understand the causes, you can eliminate the odor and keep it from coming back.
Why Your Toilet Smells Like Urine
There are several reasons your toilet may give off a urine smell. Some are simple cleaning issues, while others point to minor plumbing problems. Here are the most common causes:
- Urine Splash Around the Base: Small splashes during use can collect around the bottom of the toilet and seep into the floor.
- Dirty Hinges or Seat Bolts: Urine often drips into the hard-to-clean areas under the toilet seat hinges and bolts.
- Leaking Wax Ring: A damaged wax ring under the toilet can allow urine and wastewater to leak into the floor, creating hidden odors.
- Clogged or Dirty Rim Jets: Mineral buildup in the bowl rim traps bacteria that produce a urine smell.
- Poor Ventilation: Without good airflow, odors linger longer and feel stronger.
- Children or Pets: In homes with kids or pets, accidents around the toilet are often the culprit.
How to Fix a Toilet That Smells Like Urine
Getting rid of the odor means targeting the source. Here’s how to handle each possible cause step by step:
1. Clean the Base Thoroughly
Urine can pool around the toilet base and seep into grout or flooring. Use a disinfectant cleaner and scrub the base, sides, and surrounding floor. Pay attention to the back of the toilet, where splashes often go unnoticed.
2. Remove and Clean the Toilet Seat
Urine often collects under the hinges. Unscrew the toilet seat, soak it in a disinfectant solution, and scrub the hinges and bolts. If the seat is permanently stained or cracked, replacing it is the best option.
3. Check and Replace the Wax Ring
If odors persist after cleaning, the wax ring seal under the toilet may be leaking. Signs include water around the base, a rocking toilet, or consistent urine smell. Replacing the wax ring involves lifting the toilet and resealing it—a task many homeowners leave to a plumber.
4. Clean Rim Jets and Hidden Spots
Bacteria thrive in mineral deposits inside the rim jets. Use vinegar and a brush to scrub under the rim. For stubborn buildup, a small wire or specialized rim jet brush can help dislodge it.
5. Improve Bathroom Ventilation
Even if your toilet is clean, poor ventilation can amplify odors. Install or upgrade a bathroom exhaust fan to keep air fresh and reduce lingering smells.
6. Handle Kids and Pet Accidents
If children or pets are the cause, clean the surrounding floor and walls with an enzyme-based cleaner. Unlike bleach, enzyme cleaners break down urine compounds at the source.

Frequently Asked Questions
Why does my toilet smell like urine even after cleaning?
Odors often come from hidden areas like under the toilet seat, around the base, or inside rim jets. If cleaning doesn’t work, check the wax ring seal.
Can urine odors soak into flooring?
Yes. If urine leaks around the base, it can soak into grout, wood, or subflooring. Enzyme cleaners are best for removing these deep odors.
Is bleach enough to remove urine smell?
Bleach disinfects well but doesn’t always remove odor. Enzyme cleaners are more effective for breaking down odor-causing compounds.
Should I replace my toilet if it smells?
Usually not. In most cases, deep cleaning or replacing the wax ring solves the problem. Replacement is only needed if the toilet is cracked or damaged.
How do I prevent urine odors from coming back?
Regular cleaning, a fresh wax ring every 5–10 years, and good ventilation are the best prevention methods.
Prevention Tips
Once you’ve solved the problem, follow these steps to prevent urine odors from returning:
- Clean under the toilet seat and hinges weekly.
- Scrub the base and surrounding floor often.
- Deep clean rim jets monthly to prevent bacteria buildup.
- Replace wax rings if the toilet becomes wobbly or starts leaking.
- Use an enzyme cleaner regularly if accidents are common.
- Install or maintain a bathroom exhaust fan for proper airflow.
