Dealing with Bathroom Condensation

  • 2 min read

What causes bathroom condensation?

While bathing and especially in the case of showering, we create lots of steam. Steam looks for the coldest surface to land on, where it will then turn back into a liquid. This is why we often see water running down our bathroom walls after a good soak! Typically, we insulate these walls by adding a water-resistant coating like tiles, wet wall panelling or acrylic panelling. However, the addition of tiling or wet wall panels doesn’t stop the condensation – it merely protects the surface behind it from damp.

In truth, there is no way to stop the creation of steam but we can help to disperse it! Half an hour of ventilation after we shower, is an excellent way of getting rid of some of that condensation.


Ways to Avoid Bathroom Condensation


Extractor fan or open window?

Building regulations suggest that the addition of a suitable extractor fan should always be considered. For optimal performance, an extractor fan should be able to evacuate the volume of air in a room no less than six times per hour.

Many extractor fans are now available at minimal extra cost. They can also come with helpful features such as, timer facilities (which can be set to run on for up to 20 minutes after you leave the room) and even humidity-stats built in. This feature detects, automatically, when there is steam in the room, the fan will then turn on to evacuate the steam; proving not just to be an economical feature but also an energy saving one too.

Chances are you already have an extractor fan, especially in a windowless bathroom, but don’t forget the easiest and cheapest solution for your home is to open a window - if you have one!

How to stop condensation on bathroom walls

To finish off, wipe your tiles down with a towel; this will significantly help to prevent the build-up of mildew around your tiles and black patches of mould from forming in your sealant.

Alternatively, once you have showered or bathed, remove the remaining water from the walls using a basic window cleaning tool (squeegee) or a more expensive version, such as a Karcher window vacuum cleaner.
