How to Fix Smelly Floor Drains: A Comprehensive Guide

Due to the humid environment of bathrooms and their enclosed spaces, sanitary conditions can be poor, especially at the floor drain. If the drainage effect is inadequate, it can lead to unpleasant odors from the floor drain. In such cases, what should be done?

What to Do When the Floor Drain Has an Odor

1. The odor from the floor drain is generally caused by clogging. Open the cover of the drain and add dish soap or baking soda into it, followed by white vinegar or alcohol solution. This can effectively remove blockages in the drain pipe. Once the blockages are gone, the odor issue will be resolved as well.

2. The smell from the floor drain primarily arises from clogging, leading to unpleasant odors. Prevention is also very important. Prepare a plastic bag, fill it halfway with water, tie the bag tightly, and place it over the drain opening. This creates a seal with the water, blocking the drain and preventing odors from spreading into the air. Of course, you can remove the plastic bag when taking a shower.

3. If the blockage is more severe, you can also use caustic soda. Using the same method, pour the caustic soda into the drain, which will react chemically with the dirt inside the pipes. Afterward, pour in some hot water. The combination of the chemical reaction and high temperature will help clear the drainage.

What Are the Dimensions and Specifications of Floor Drains

1. Floor drains come in different models. For example, some are odor-proof with diameters of 3 inches or 4 inches. Be sure to measure accurately and choose the appropriate size.

2. Floor drains also have various shapes, including circular, square, or rectangular. Their size may vary, with dimensions of 90mm or 150mm.

3. There is also a type of ultra-thin floor drain, primarily featuring a square panel with a depth of 10cm and a thickness of 1.5cm, which tends to have better odor-proofing and faster drainage.

In summary：the content above describes how to address odors from floor drains. The fundamental solution is to resolve the pipe blockage issue, which will effectively prevent odors from the drain, resulting in a smell-free floor drain.
