How to Fix Bad Smell Under Your Laundry Room Sink: Effective Solutions to Eliminate Unpleasant Odors

Dealing with a bad smell under your laundry room sink is a common household issue, but it doesn’t have to persist. These odors typically stem from plumbing problems, trapped moisture, mold, or residue buildup. As a designer, I always advocate for solutions that not only resolve the issue but also promote a clean, fresh, and organized space. Below, I’ll walk you through a step-by-step guide to identifying and eliminating unpleasant smells under your laundry room sink—while subtly incorporating design tips for lasting freshness.

1. Identify the Source:
2. First, clear out everything from under the sink. Inspect the area for visible mold, mildew, leaks, or pooling water. Sometimes drainage pipes, u-bends, or garbage disposals can be culprits.
3. Clean the Drain and Pipes:
4. Pour a mixture of baking soda and vinegar down the drain to break up organic buildup. Allow it to fizz for a few minutes, then rinse with hot water. For stubborn blockages, consider a drain snake but avoid harsh chemicals that might damage your pipes or nearby surfaces.
5. Check for Leaks:
6. Even a minor drip can encourage mold growth and musty odors. If you find any leaks, repair them promptly with plumber’s tape or by replacing faulty parts.
7. Combat Mold and Mildew:
8. Wipe down the cabinet interior with a diluted bleach solution or store-bought mold remover. Be sure to ventilate the area well. Let everything dry thoroughly to prevent spores from returning.
9. Improve Ventilation:
10. Odors linger in damp, enclosed spaces. Consider adding a small moisture absorber or portable dehumidifier. For a design-forward touch, integrate aesthetically pleasing ventilation grilles or cutouts into the cabinet door to encourage airflow while maintaining visual appeal.
11. Prevent Future Odors:
12. Store cleaning supplies in well-sealed containers. Use shelf liners that are easy to wipe down. As a designer, I often suggest installing a custom under-sink organizer, which keeps items away from damp surfaces and helps you spot issues early.

Addressing under-sink odors isn’t just about cleaning—it’s about rethinking the space for ongoing comfort and functionality. From a design perspective, leveraging a home designer tool can help you visualize organizational improvements under your sink or throughout the laundry room, making upkeep much easier in the long run.

Tips 1:

Consider using natural odor absorbers like activated charcoal packets or baking soda containers. These discreet solutions maintain freshness without adding visual clutter—and they’re easy to replace as needed. For a seamless look, choose storage bins and liners in colors that complement your laundry room’s color scheme.
