Steps you can take to reduce condensation in the bathroom

By EnviroVent May 25, 2021

Did you know that when you take a shower or bath, up to 1.7 litres of water are released into the air as steam.  When this water comes into contact with cold surfaces such as walls or ceilings it forms condensation which can, if not treated, cause damp and mould problems that can affect your health.

In most homes, the steam released by bathing is one of the main causes of condensation, and as such, if you live in a home where condensation is becoming a problem, the bathroom is the first place to start when solving the issue.

Close the door when you bathe

This might seem obvious, but you’d be surprised how many people shower or bathe with the door open.  If you leave a door open when you are in the bath or shower, your extractor fan will not be as effective at removing moisture from the air and the steam will easily escape into the rest of your home where it can settle and form condensation patches far away from the source.

Close the door during your bath or shower and leave it closed for around half an hour after you have finished and left the bathroom to allow the moist air to escape outdoors rather than allowing it to escape into the rest of your home.

Use your extractor fan or open a window

Most bathroom extractor fans are connected to the light circuit and will continue to run for a short period after the lights are turned off.  You can also choose extractor fans such as the Cyclone 7 which use sensors to measure the amount of moisture in the air they are treating and adjust their power accordingly.

Running an extractor fan during your bath or shower and ensuring that the door is closed is the single most effective way of reducing moisture in your home and preventing condensation from forming as a result of your bath. 

If your bathroom does not have an extractor fan installed, or it is not powerful enough, you can open a window in the bathroom to improve the air flow and help reduce the humidity.

Avoid drying towels on bedroom radiators

After your bath or shower, it can be tempting to put your towel over a bedroom radiator to dry out.  This is a bad idea.  If you think about the weight of a wet towel compared to a dry one, you realise how much water the towel is carrying through into a different room.  When laid on a radiator, the moisture from the towel will evaporate into the air of your bedroom where it will quickly condense onto cool surfaces.  This can be a bigger problem than it would be in the bathroom, where a modern extractor fan would recognise the increased moisture levels as the towel dries and increase air flow to compensate.

Wipe down wet surfaces after use

After a shower, it is a good idea to wipe down wet surfaces such as the shower door and tiled walls with a squeegee.  This reduces the amount of moisture left to evaporate after you have left the room and sends it into the drain where it won’t contribute to condensation elsewhere in your home.
