How To Get Rid Of Musty Smell In Bathroom Quickly and Easily

One of the most common odor problems people encounter in their house or apartment is the musty smell in the bathroom which is really hard to get rid of. The damp environment and non-circulating air is perfect to promote mold growth which is not only an aesthetical issue but also a health concern, so it needs to be treated asap. Here I share what factors I check when I experience that my bathroom smells like mildew and give tips on how to prevent it.

Why does my bathroom smell musty – Top causes of mildew-like odors

The problem we face when noticing mold smell in the bathroom is complex and there can be several reasons behind it. Sometimes, fungal growth is clearly noticeable: you see black spots on the ceiling or pinkish, yellowish areas on the shower curtain, but sometimes the source of musty odors stays hidden. Here I list the main reasons behind the stagnant smell in the bathroom so it becomes easier to localize where that mildew-like odor is coming from.

Growth of fungus

When fungus starts growing on your bathroom surfaces, the result would be musty smells. Mold grows well in dark and watery surfaces, including the tiled, fiberglass, or wooden surfaces. Therefore, if you notice black spots on the ceiling, in the shower grout, mold on the shower curtain, musty-smelling drains, or a sour smell in your bathroom, then fungus has started growing.

That said, it’s the leading cause of the musty smell coming from your bathroom. Grown mold can be quickly cleaned through DIY tricks, but if it has covered an area larger than a square foot, you might need a professional to clean it off.

Excessive dampness

Dampness attracts mold spores present in the air that flows through the bathroom to settle on surfaces and grow. Excess moisture also indicates poor bathroom drainage.

If most surfaces in your bathroom are ever wet, it means that water doesn’t flow out efficiently, and you might need to have the bathroom checked for leakages, defective mortar, or cracked walls.

Poor ventilation

If your bathroom doesn’t have proper ventilation, mold is likely to grow, leading to musty smells. Bathrooms are continually moist, and if air doesn’t flow undisturbed, the moist/humid environment formed could attract the growth and thrive of mold.

The easy way to tell if your bathroom has mold formation is by checking whether there are brown, black, or white spots on the walls or if there is a musty smell. Ventilation is a key thing to pay attention to especially if your bathroom doesn’t have a window.

Dirty surfaces and drains

One key catalyst for mildew to grow fast and densely around the bathroom is dirty surfaces and drains. If you leave basements, closets, dresser drawers, towels, and bathmats dirty, you might quickly start noticing mold growth.

That is because dirt and dust particles are the food mildew needs to grow soon after the temperature and moisture hit the proper levels. Keeping the surfaces around the bathroom clean is the first step to preventing bathroom smells.

If you can’t find the source of mildew odor in your bathroom, you should check the drains too: dirt sometimes stays hidden behind the stoppers and pop-ups!

How To Get Rid Of Musty Smell In Bathroom

After discovering mold around your bathroom, the immediate best step is getting it cleaned since those black spots cause not only musty smells but can cause health problems too. If the situation is not too developed, the issue can be easily addressable by yourself and wouldn’t require complex tools. However, some mold formation problems would need a professional to resolve.

Wash off the surfaces

The quick way to clean off the musty stench and achieve that fresh-smelling bathroom is by cleaning surfaces where the mildew has formed. Start by wiping off the black spots from the bathroom walls and removing mold from the tile grouts, wash off the hand towels, bathroom rags, window, and shower curtains, and every other part of the bathroom that’s mildew infested.

Consider getting the work done in an eco-friendly way. Cleaning the bathroom with vinegar and baking soda is a safe and effective way to get rid of dirt and odors. Another natural cleaner is Sodium Tetraborate (Borax) which is a powdery white substance derived from boron.

One instance a bathroom smells musty is when you have leaks or clogged drains. The solution for such problems is simple: get the leak repaired, clean, and deodorize the drains!

A dripping faucet, leaking shower, or toilet can be fixed by yourself too if the issue is not too serious, but the best is to get a plumber because sometimes the leakage is hidden behind the walls.
