How to Eliminate Foul Odors from Floor Drains in Bathrooms

When it comes to bathrooms, the most memorable impression often involves unpleasant odors, which are usually caused by the floor drain. So, what should you do if your bathroom floor drain emits foul odors? Let’s take a look.

What to Do If the Bathroom Floor Drain Is Smelly

1. Replace the old floor drain with a new one, preferably a water-sealed drain, to ensure that water can be replenished in a timely manner. Be sure to add water to the drain regularly to reduce odors.

2. Use a discarded wet towel to cover the drain opening to prevent the spread of odors and bacteria.

3. Clean the outlet with a deodorizing agent, or place some tea bags or bamboo charcoal in the area as odor absorbers.

Why Does the Bathroom Floor Drain Smell?

1. Different products have varying effectiveness. For instance, the water seal height of a water-sealed drain is typically regulated by national standards to be at least 50 mm. However, many manufacturers produce drains with a water seal height of only 10 to 20 mm, which is only half of the national standard. This failure to meet standards makes it normal for the bathroom to experience foul odors, so it's important to pay attention to the water seal height when purchasing a floor drain.

2. Even if the traditional drain style meets the 50 mm seal height standard, it may still emit unpleasant odors after several days or periods of time. Additionally, the narrow and curved pipes provide a larger area for dirt to accumulate, which can lead to the breeding of bacteria and pests, significantly affecting daily use.

3. The spread of bacteria is mainly due to environmental pollution, which allows bacteria to proliferate. As many people know, sewer pipes that remain dark and damp for extended periods—especially those that discharge waste—naturally breed a large number of bacteria. This can then spread throughout the living space, posing a significant threat to the physical and mental health of residents.
