Why Does My Laundry Room Smell Like Fish : Identifying and Solving the Fishy Odor in Your Laundry Room

If you’ve walked into your laundry room only to be hit by a distinct fishy odor, you’re definitely not alone. While unpleasant, this smell typically signals an underlying issue that needs to be addressed. The scent isn’t often caused by actual fish, but rather by electrical problems, plumbing issues, or mold growth—each requiring prompt attention.

Common Causes:

1. Electrical Issues: Overheating wires, outlets, or appliances (especially dryers or washing machines) can emit a fishy, burning odor. This is due to the breakdown of heat-resistant chemicals used in wiring insulation.
2. Plumbing Problems: If your laundry room has a sink or a floor drain, stagnant water or debris buildup can cause bacterial growth, which sometimes gives off a foul fishy smell. Sewer gases escaping from dried-out drain traps are another culprit.
3. Mildew & Mold: High humidity and warmth make laundry rooms a perfect breeding ground for mold and mildew, especially if there are leaks or damp clothes left unattended. Mold can sometimes produce odors similar to fish.

Before masking the odor with air fresheners or cleaning products, it’s essential to identify and resolve the root cause. Ignoring electrical smells, in particular, can pose a fire risk. Try unplugging appliances to see if the scent dissipates; if so, consult a qualified technician immediately.

As a designer, I often find that deliberate planning and the right tools can prevent these problems. Incorporating proper ventilation, thoughtful layout, and moisture-resistant materials reduces the risks of odors and long-term maintenance issues. For those designing or renovating their laundry area, using an advanced home designer tool can help you strategically select layouts and materials that resist moisture and make ongoing cleaning easier—ultimately avoiding odors like these in the first place.

Tips 1:

Ensure your laundry appliances are regularly maintained. Clean out washing machine filters and dryer vents, and periodically inspect plumbing for leaks or standing water. Adding a dehumidifier or an exhaust fan can also help keep the space dry and odor-free.
