The bathroom is naturally more humid than other rooms in the home, because showering and bathing creates water vapour. To maintain a healthy indoor climate and prevent mould build-up, you need to ventilate your bathroom properly.

Why bathrooms should be aired regularly

Regular showering and bathing creates a lot of water vapour in the bathroom, resulting in high humidity levels. This moisture is deposited on the floor, walls and windows. If the humidity remains high and condensation accumulates, this creates an ideal breeding ground for mould spores. Mould in the bathroom isn’t only unsightly – it is also harmful to your health. You should therefore take preventative measures in good time to prevent mould growth. If you ventilate the bathroom properly several times a day and reduce humidity, mould has little chance of spreading. We recommend that you air your bathroom immediately after bathing or showering so that the moisture is removed immediately.

Tip

Are you wondering how you can ensure proper ventilation to counteract mould in a windowless bathroom? If you have an internal bathroom, you can set up a room dehumidifier or install a ventilator. Or, if the bathroom is favourable located in your home, you can open the bathroom door and open the windows in the adjoining rooms to create a flow of air.

Avoid mould growth

To prevent mould in the bathroom, you should ensure that the room is ventilated regularly and properly. Always keep an eye on the humidity level – it should be between 50 and a maximum of 70 per cent. The ideal option is to invest in a hygrometer for to monitor humidity levels. This will help you keep track of things.

You should also avoid making certain mistakes when airing, which can further increase the humidity in the room. Refrain from opening the door first and then the windows. This spreads the existing high humidity throughout the room, encouraging the growth of mould. The risk of mould growth also increases if you forget or delay in airing the bathroom after your shower. In this case, the resulting condensation has time to settle on all the fixtures, tiles and walls and will dry out very slowly. You can then only prevent the formation of mould by wiping the bathroom dry promptly and then airing it thoroughly.
