You can even leave the bathroom door open slightly to prevent that humid air from getting trapped. Improving ventilation is key to sending mold spores packing before they proliferate.
If the door is closed, the humidity will stay high for quite a while, increasing the risk of mold to build up... After showering/bathing, leave the door half open to air out the bathroom.
If you have not already done so, ventilate the room immediately until the hygrometer shows an acceptable level. The perfect temperature for the bathroom is around 23 degrees. Ideally, you should always leave the heating on in the bathroom. A grout-free bathroom is a particularly effective way of preventing mould.

It's generally a good idea to close the bathroom door when you shower to prevent steam and moisture from spreading to other areas of your home, which can lead to issues like mold and mildew. It also helps maintain privacy and keeps the warmth inside the bathroom.
In the feng shui world, water equates to wealth. And because water is so frequently flowing in bathrooms, that makes this a hot spot for chi. But an open bathroom door is similar to an open toilet lid—it gives good chi the opportunity to escape.
Open windows allow moist air to escape and fresh air to enter. This helps reduce mold or mildew growth. In a windowless bathroom, leave the door open during and after bathing. If your home has relatively low humidity (below 50%), the air that escapes your bathroom can help increase the overall humidity.
For medium-sized bathrooms, use 80 to 99 CFM bath fans. For large bathrooms that are over 100 square feet but under 150 square feet, use over 100 CFM bath fans. For extra-large bathrooms, add 50 CFM for every toilet, 50 CFM for every bathtub or shower and 100 CFM for a jetted bathtub.
It should swing in. All commercial and residential buildings are generally built to have bathroom (and bedroom) doors that swing inward. This is also done for safety as you don't want to hit someone with the door as they are walking by.
Run the Fan for 20 Minutes Post-Shower: This ensures all moisture is removed from the air. Leave the Door Slightly Ajar: Allowing some fresh air to flow into the bathroom helps the fan work more effectively.
Solution: Bleach
Best For: killing mold on the surface of nonporous surfaces like tiles and sinks. One part bleach to two parts water added to a spray bottle. Spritz the hard surface areas with this solution and let dry. The mold should disappear within minutes.
The most common causes of bathroom mould are lingering moisture caused by lack of ventilation, leaky toilets, sinks, and plumbing pipes, as well as damp cellulose materials. The high moisture content and heat in the bathroom environment can increase humidity.
Black mould spores need moisture to cultivate fungal growth. If the relative humidity in the home is over 50%, then excess condensation sets the stage for invisible mould spores to settle back onto the substrate and start the cycle once more.
In many European homes, however, the tradition is to keep bathroom doors securely closed at all times. I think this is probably a heritage from the days when 'water closets' were malodorous places and one sought to keep unpleasant odors out of the rest of the house.” Merry Andrews.
Scientists have weighed in with their own woeful conclusion: Neither is a solution to stopping the spread of dangerous germs. Microbiologist Charles Gerba and his research team at the University of Arizona determined there's little difference whether you leave the lid up or down.
According to Vastu Shastra principles, the ideal directions for constructing a bathroom are the northwest or southeast corners of the house. Having a bathroom in these directions is believed to facilitate better energy flow and harmony within the home.
Close the Bathroom Door
This prevents moist air from escaping into the rest of your house where it can cause condensation to form in other rooms. Keeping the door closed also makes the extractor fan more effective at removing the humidity from the bathroom and helping with overall bathroom mould prevention.
Speaking to the same issue, VP Eric Ding explains that, “propping the bathroom doors open allows our security staff to quickly check and sweep the bathrooms for illegal, inappropriate, and unsafe behavior.”
Material yield: Floor and ceiling gaps allow manufacturers to size doors and panels for optimal material yield, which lowers costs. Sloping floors: Commercial restroom floors often slope to a drain. Doors without floor gaps are likely to interfere with these sloping floors.
Keeping your shower doors closed at all hours of the day locks in moist air and can lead to mold. After you shower, the interior space is at its wettest point. Try to keep the doors open for a half hour or so until the steam clears. If you have a fan in your bathroom, make sure to turn it on and let the air circulate.
Pro Tip: Install the exhaust fan outside the bathroom. Doing so will extract the humidity and odor from the bathroom while giving way to clean, fresh air. The size of the exhaust fan should be 1 cfm-square-foot of the floor space.
Opening windows is one of the most effective methods to control areas prone to mold growth, like a kitchen or bathroom. However, if there is already significant mold growth, like mold spreading from one area or room to another or a patch of mold bigger than a few feet, you will want to call a mold abatement company.
Limited Space: In smaller bathrooms, adding windows can reduce available wall space for mirrors, storage, or other functional elements. Potential Water Damage: Windows in shower areas or near tubs need to be properly sealed to prevent moisture from damaging the window frame or surrounding walls.
