Think about how often you use your bathroom. Now, think about how often your bathroom steams up. It is a problem that every bathroom faces, no matter how large it is, or whether it has windows or not. Obviously the smaller the bathroom is the worse the ventilation is, especially those without any windows at all that have built inside the building without an exterior wall. Ventilation is massively important in any property, but especially so within bathrooms, where there is consistent use on a daily basis and a steaming up process that can cause plenty of complications further down the line if left unresolved.
A bathroom very quickly steams up, mists and becomes foggy whenever a hot bath or shower is run. This takes place as the hot air created from those processes moves and hits the surfaces of the bathroom that are much colder in temperature, such as any mirrors, glass panes around the shower or bath, and any windows. If you allow this poor quality air to develop through a lack of proper ventilation in the bathroom and other areas of the property, it can quickly cause problems that are difficult to overcome, for both the structure and aesthetic of the property, and the health of any one living in the property.
The first thing that happens with poor ventilation is that mould can begin to develop. This happens most frequently in shower cubicles where there is little immediate ventilation, and can cause rusting around taps, showerheads and cause mould to develop on any tiling present. Over a long period of time, if mould is allowed to develop it can begin to overcome the bathroom as a whole and become the primary focus on every surface. This can cause health complications for any person who is regularly using the bathroom. Over a shorter period of time, condensation and lack of ventilation can cause slippery surfaces.
If there is no resolution to poor air quality, the development of mould and constant condensation in a bathroom can cause cracked tiles and walls, the peeling back of any paint and other decorations, and a general demise of the quality of the finish to the bathroom. Rusted taps and fixtures will also lead to a lower effectiveness of use over time.
Keeping a well-ventilated bathroom is vital therefore. If there is a window in the bathroom, even a small window, always make sure it is open when you are using the bathroom or running hot water for a prolonged period of time. The longer you can keep the window open the better (though of course during cold winter months this might not always be practical). In most bathrooms, but especially those without any windows, there is a call for the installation of extractor fans. These can run during the use of a shower or running of a bath, and for a few minutes after use to pull out the hot air and prevent steaming. Dehumidifiers are also a good option to remove excess moisture.
