How to Ventilate a Bathroom Effectively

Proper bathroom ventilation helps air to circulate your bathroom and limits the build-up of moisture from baths and showers. Ventilation is necessary for all bathrooms, but especially window-less bathrooms or wet rooms. It is important to improve bathroom ventilation in your home to create a safe space. In this blog post we will discuss how to ventilate a bathroom effectively and share some bathroom ventilation options.


The Importance of Effective Bathroom Ventilation


  • To act within UK government regulations

A UK bathroom must be ventilated by either a window or an extractor fan.

  • Reduces mould

Mould builds up a result of excess moisture. When you improve your bathroom ventilation, you can stop mould appearing on your walls and in the grout between your tiles.

  • Improves air quality

Mould and indoor airborne pollutants can cause serious health issues, so it is important to take your bathroom ventilation options seriously. A good ventilation system can reduce the level of contaminants in the air and improve your air quality. Plus, improved bathroom ventilation removes any unpleasant odours.

  • Protects your bathroom

Proper bathroom ventilation improves the life of your bathroom by reducing condensation and mould, which can wreak havoc on your aesthetics. Protect your walls and bathroom fixtures and fittings, such as radiators, from peeling, damp and mould damage.

  • Extractor Fan

Extractor fans are designed to extract the moisture, odour and stale air from your bathroom to outside. There are many types of extractor fan available, depending on the distance between the fan and how far the air must travel to reach outside. Axial extractor fans are good if your bathroom has an outside wall, whereas centrifugal and inline extractor fans are designed for longer distances to an external wall.

  • Dehumidifier

A dehumidifier is ideal for smaller or windowless bathrooms. They work by extracting humidity from moist, hot bathroom air, and trap condensation so it doesn’t spread around the room.

  • Open a Window

Leaving your window (or door) open will also help to ventilate your bathroom and increase the circulation of fresh air around the room. However, leaving your window open day and night may not always be a practical option, so the installation of either an extractor fan or a dehumidifier is recommended.

Each of these bathroom ventilation options will help you to reduce condensation, prevent mould and extend the life of your bathroom. You can fit an extractor fan or dehumidifier by yourself, or have one integrated as part of your bespoke bathroom design.

Top Tips to Improve Bathroom Ventilation


  1. Upgrade your extractor fan to a moisture detection fan

An extractor fan with moisture detection functions with a humidity sensor as opposed to a timer. Therefore, your fan won’t turn off until the humidity level has decreased to the optimal level. These fans also tend to be quieter when running.

  1. Clean your extractor fan

First, make sure that your extractor fan isn’t switched on. Then, take a damp sponge or microfibre cloth to clean out any dust from the grille and surrounding area.

  1. Leave your extractor fan running

Leave your extractor fan running for at least 15 minutes after your bath or shower, rather than switching it off straight away. This way, your extractor fan can do it’s work properly and remove all the moisture from the room.

  1. Wipe up puddles

Wipe up any puddles in your bathroom as soon as you notice them, to make sure that your bathroom dries out as quickly as possible.

  1. Don’t hang wet towels in a damp area

If your bathroom is already damp, take care not to hang your wet towels to dry as this will add extra moisture to the room.

  1. Leave your shower door open after use

Help out your extractor fan or dehumidifier by leaving your shower door open after you use it. An open door allows the fresh air to circulate through the space and lets it dry out more quickly.

  1. Open your window, if you have one

If you have a window in your bathroom, leave it open while you are in the bath or shower and leave it open for some time afterwards to improve your bathroom ventilation. If you don’t have a window in your bathroom, opening your bathroom door should do the trick.
