If you want your bathroom to be free from mould and mildew then ventilation is key in any bathroom. The key is to make sure you get the correct sized fan for the bathroom space.
Bathroom fans help improve airflow and they work by extracting moist air from the room. Lingering odours will also be banished from the room if you invest in a good bathroom fan design. New build homes have to comply to strict guidelines for ventilation so you will find most issues with ventilation appearing in older properties.
Due to the amount of water that is used in a bathroom water and moisture are an everyday issue to combat. Where there is moisture this will result in the build up of mildew and mold if the area isn’t kept well ventilated. Many people dis like the look of vents in the walls and eventually these are covered when painting or tiling. This is not a good idea and will result in numerous issues later down the line. Now bathroom extractor fans look a lot more sleek and modernised rather than the traditional designs that were unsightly. You will find that even opening a window when showering will still leave moisture in the air and is not a long term solution.
Bathroom extractor fans for households come in two main sizes which are 100mm and 150mm. The 100mm size in most cases will suffice but the larger fans may be considered in bathrooms greater than three metres squared. A more powerful fan may be required in specialist bathroom situations such as particularly cold or north facing bathrooms.
Bathroom extractor fans can be installed in the ceiling or in the wall depending on which model is purchased. Many bathroom extractor fans are quiet even when they operate resulting in less noise pollution in the home. If you are unsure as to which fan will work in your bathroom then consult with the manufacturers, retailers or bathroom installer.
