    • Lack of proper ventilation and drying process. As toilets and bathroom always wet eventhough shower activity is only 14 times a week, after bowel movement or ablution evaporation is slow.
    • No shower screen that causes water splash and damp patches in bathroom floor and wall
    • Cleaning up the contamination area with hydrogen peroxide-based cleaner such as HG mould spray
    • Remove the contamination bathroom toilet with the new one that contains fungicides.
    • Install the shower screen to avoid water splash all over the bathroom
    • Get the water direct into the water drain therefore the bathroom floor will dry faster
    • Install the proper ventilation in the bathroom to provide sufficient heating and ventilation
