How To Prevent Mold In Bathroom Without Fan

Upon entering the bathroom for a relaxing shower after a tiring day, your attention is drawn to the unsightly mold. This can be quite repulsive and harmful to the skin if left untreated, as mold tends to grow in areas with retained moisture.

While using a fan can be an effective solution, what can be done in the absence of one? Without delay, let’s explore some options below.

1. Use of Semi-Gloss Paint

Painting your washroom is a great way to make it look more appealing. However, when you utilize semi-gloss paint, so you really should do more than just decorate the bathroom. One such type of paint will give the shower a slick exterior that will not help mold growth.

Thinking of those slick paint walls makes me drool over it. They can be washed with the least effort given the difficult condition for mold survival.

It’s also a smart option to be using stronger gloss paint, like semi-gloss. Semi-gloss paint creates a tougher, smoother texture that is more resilient to wreckage building up and discoloration.

Flat paint (which is commonly used in bathrooms) is a less expensive form of paint that lacks the glitter or slick exterior that gloss paints have. Plain paint is the most prone to mold growth.

2. Go for Anti-Fungal Spray

In the absence of a fan, you can also enhance the resilience of your bathroom to mold by sprinkling it with an anti-fungal spray.

Because the lack of sufficient airflow leaves the bathroom susceptible to mold growth, the unique spray will slow down the rate at which humidity accumulates in the bathroom, significantly decreasing mold formation.

Spray it in those places where you find molds too irresistible. As the name suggests, the spray works alongside fungi, ridding all the impurities in one go.

 3. Seal The Grout of The Tiles

Bathroom floors are most susceptible to mold. So what you can do is seal the gap between the tiles to destroy the entire being of mold.

The simplest approach to help avoid mold formation on your tile is to have it professionally sealed. Sealing is the final stage in tile installation, and many people skip it. Coating the grout provides it with a glossy surface and repels humidity, which prevents mold formation.

If your grout has never been coated, or it will have to be enclosed again (they don’t stay forever), it is a simple step to prevent mold from growing on it.

Alongside caulking, cleaning the grout with a basic cleanser (like dish detergent) and a brush while having a bath is a smart option.

So if the grouting is well sealed, mold could still grow if dirt and dust accumulate on it. This is due to mold’s ability to thrive in dust and other biological materials which serve as a food supply for mold.

Mold can still grow on the tile if debris accumulates in a thin coating. Dirt, on the other hand, is less likely to attach to the grout in the first instance with a well-sealed grout.

4. Weekly Clean-Routine

Almost once every week clean the entire bathroom and wipe the floor to keep the mold at bay.

The basin and bathtub weren’t the only areas of the washroom that should be maintained dry. As a general rule, the entire item in the washroom must be maintained water-free.

As previously said, cleaning your showerhead on a routine basis helps prevent mold spores from accumulating and being discharged into your bathroom.

Filling a bag with vinegar, a mold-killing agent like CLR, or anything that could kill mold, and then immersing the shower in the bag for 30 to 60 minutes will be sufficient to take rid of this. Cleaning your shower heads at least once a month for optimum benefits.

5. Keep Windows Open

Moisture accumulates fast in spaces with little or no ventilation or breeze, this is why this situation can come into existence since your washroom lacks a fan. If your bathroom has a window, try and keep it open as much as possible.

It is probably the easiest way to prevent mold growth and let the moisture out of your bathroom. If your shower or bathroom has a window then all you need to open the window for at least 20-40 minutes after each bath or shower.

This is one of the perfect methods to ventilate your shower without using mechanical exhaust fans for your bathroom.

A large portion of the moisture would be carried away by the airflow. Let the washroom doors open at the same moment to build a good crossing airflow and improve ventilation. If your bathroom does not have a window, having the door open should be your next best option.

6. Reduce Moisture Using a Dehumidifier

If you have a washroom that lacks a fan, or windows and is frequently dark, here are some of your finest options. You can switch it on yourself after every bath, or you could just let its automated moisture sensor switch it on.

Simply turn on the humidifier for several hours every day and adjust it so that it thoroughly dries the air and sucks out enough humidity as possible.

Smaller dehumidifiers would require regular water tank emptying, but bigger ones can have piping run straight into the bathtubs for automated emptying.

By lowering the level of moisture in your bathroom, you stand a good chance of preventing mold from growing in the bathroom.

7. Repair All Leaks

When there is leakage in the washroom, this could provide another pathway for mold to grow and flourish. Such leakage is typically the source of excessive water in the bathroom.

A leak piping may dump additional water into the bathroom during water transfer whilst a leaking ceiling may also channel water into the bathroom via the roof, resulting in walls and ceiling mold.

Bathroom mold isn’t just caused by the water in your bath or shower. Breaks can also enable humidity to gather and mold to develop. Repair all those points which leak water. If you can’t do it by yourself, ask for a plumber to lend you a hand.


If you’ve been wondering how to prevent mold in a bathroom without a fan, these are among the things that keep mold away in your washroom even if a fan isn’t fitted. Combine the aforementioned steps to have the best results.

The greatest strategy to avoid mold, like with any other preventative measure, is to minimize the conditions that allow it to form in the first place.  Also, do make sure that you keep your bathroom as dry as possible.
