How to Tackle a Smelly Drain in Your Laundry Room: Effective Solutions for Odorous Drains in Laundry Spaces

Dealing with a smelly drain in your laundry room can be frustrating and unpleasant, but understanding the root causes will help you find the right solution. Odors commonly stem from trapped debris, soap scum, mold, or bacteria growth within the pipes or the drain trap. Sometimes, infrequent use or a dried-out P-trap allows sewer gases to escape into your home. Start by running hot water down the drain to clear away minor blockages. You can also pour a cup each of baking soda and white vinegar into the drain—this natural reaction helps to break down odor-causing buildup. After letting it sit for at least 30 minutes, flush with more hot water. For persistent smells, try removing and cleaning the drain cover, using a long brush to scrub the interior sides. Don’t forget to check for blockages in the washer drain hose as well.

As a designer, I believe that solving functional issues is just as important as aesthetics. A smelly drain can be a sign that your laundry room requires a better layout or upgraded fixtures to improve air flow, drainage efficiency, and even ease of cleaning. When planning or renovating your space, I recommend using a laundry room design tool to visualize solutions such as well-placed ventilation, accessible drains, and moisture-resistant materials. Incorporating a design-oriented approach ensures both beauty and practicality, and keeps your laundry area fresh and welcoming.

Tips 1:

If your laundry room is prone to recurring odors, set a maintenance routine: flush drains monthly with hot water and vinegar, keep the area well ventilated, and inspect for leaks or standing water around machines. Consider using decorative grates or covers that allow airflow while hiding the drain, blending hygiene seamlessly with overall room aesthetics.
