10 Best Quiet Bathroom Fans 2025 in the UK

The Airflow iCON 30 Extractor Fan stands out in the quiet bathroom fans category due to its low noise level of 33.3 dB, making it a great choice if you prefer a peaceful environment. The fan's innovative iris shutter technology is a significant advantage, as it helps prevent backdraughts and keeps your bathroom warm, which can assist in reducing energy bills. The airflow capacity is solid, with a flow rate of up to 33 l/s (121 m³/h), ensuring efficient ventilation. Energy efficiency is another strong point, operating at just 10.7 watts, aligning well with eco-conscious preferences and reducing electricity consumption over time.

Installation might require a bit of planning as it needs a 110mm hole for wall mounts or a 160mm hole for ceiling mounts, along with a proper alignment of vapor barriers, which might be a bit complex for some. The flexibility of optional control modules, which allow you to customize the fan with timers, humidity sensors, and motion sensors, is a notable feature, although these modules are sold separately and add to the cost. Aesthetically, the fan is versatile with multiple color options like silver, chrome, anthracite, and navy blue, allowing it to blend with various bathroom decors.

A 3-year warranty and compliance with UK building regulations provide additional peace of mind. However, it's worth noting that while the fan is designed for easy installation, the added complexity of module customization and specific installation requirements might necessitate professional help for some users.

The Xpelair C4TSR Extractor Fan is notably designed for those seeking a quiet solution for bathroom ventilation. It operates at a remarkably low noise level of 16 dB, making it an excellent choice for users prioritizing a peaceful environment. The fan features Ghost Airmovement technology, which contributes to its near-silent operation. It offers two-speed options, allowing users to choose between 15 or 21 liters per second (l/s) of airflow capacity during installation. While this range is sufficient for smaller bathrooms, it might not be adequate for larger spaces requiring higher airflow capacities.

On the energy front, the fan is relatively efficient with power consumption ranging between 6.3 to 7.0 watts, depending on the speed selected. This energy efficiency can be a boon for those looking to minimize electricity costs while maintaining effective ventilation. The fan's design accommodates both circular and square baffles, providing flexibility in style to match different bathroom decors. Installation is straightforward as it is corded electric and includes necessary components like the back shutter and baffles.

With an IPX4 rating, it is protected against water splashes, making it suitable for bathroom use. The fan's lightweight and compact design further aid in easy installation. However, potential users should consider the installation requirements to ensure compatibility with their existing setup. The included timer feature adds convenience, as users can set the fan to operate for a predetermined duration, contributing to energy savings. The Xpelair C4TSR Extractor Fan is best suited for smaller bathrooms where noise reduction is a priority. Its sleek, modern style and efficiency make it a competitive option, although those with larger bathrooms or higher airflow needs might need to explore alternatives.

The Airflow iCON 15 Bathroom Extractor Fan is a notable choice for those seeking a quiet and energy-efficient bathroom fan. With a noise level of just 28.8 dB, it operates quietly, making it suitable for smaller bathrooms or en-suites where noise might be a concern. Its 9.4W power consumption ensures energy efficiency, translating into potential savings on electricity bills. The fan delivers an airflow capacity of 19 l/s, which is effective for small to medium-sized bathrooms, ensuring adequate ventilation.

One of the standout features is the iris shutter technology, which automatically closes when the fan is not in use, preventing backdraughts and cold air entry. This feature helps maintain bathroom warmth and enhances energy efficiency. However, the fan is sold as a basic unit and lacks advanced controls, which must be purchased separately if you desire additional functionality like timers or humidity sensors.

Installation is relatively straightforward, requiring a 110mm hole for wall or ceiling mounting, and suitable for those familiar with basic DIY tasks. Professional installation is recommended to comply with UK building regulations and ensure proper functionality. The fan is aesthetically adaptable with multiple color cover options, allowing it to blend seamlessly with various bathroom decors. Despite the need for additional control modules for enhanced features and its basic design potentially not catering to larger bathrooms, the iCON 15 is a reliable and efficient choice backed by a 3-year warranty and strong customer support from Airflow Developments.
