Irish bathrooms take a lot of moisture. Hot showers, poor airflow and cool outside temperatures leave steam with nowhere to go, and over time that shows up as fogged mirrors, peeling paint and black mould around the ceiling. A good extractor fan removes that damp air before it settles. This guide walks through the STERR bathroom fan range and how to pick the right one.
Three families to suit different tastes
The BFS range has a clean tempered-glass front and is our most popular choice for modern bathrooms. The LFS range uses a brushed metal front and comes in finishes such as gold, silver and black for a more decorative look. The BSL range is a compact fan with a short 46 mm flange, made for shallow wall cavities where a standard fan will not fit.
Colours and finishes
Bathroom fans do not have to be white. The BFS glass-front range comes in black, matt black, grey and white, so you can match the fan to your tiles, taps and fittings instead of settling for a plain white square. The silver option uses a brushed metal front rather than glass for a more industrial look, and the LFS range adds gold. The finish is the only thing that changes: performance, quiet running and features are the same across every colour.
Prefer a fan that disappears into a dark bathroom? The black LED model pairs a black glass front with a soft backlight for a modern look at night.
Shop by colour: white, black, grey and silver or gold.
Get the size right first
This is where most mistakes happen. Bathroom fans are sized by their duct diameter, and 100 mm (4 inches) is the standard for almost every Irish bathroom. We also stock 125 mm and 150 mm versions for larger rooms or longer duct runs, but these need matching ducting. Before you order, measure the diameter of your existing duct or wall vent. If it is 100 mm, choose a 100 mm fan.
Pick the features you will actually use
- Standard: switches on and off with the light or its own switch.
- Timer: keeps running for a set time after you leave, clearing lingering steam.
- Humidity sensor: the BFS100H starts automatically when humidity rises and stops when the air is dry, so it works even when you forget.
- LED backlight: a soft decorative glow for a modern finish.
- Motion sensor: starts when someone enters the room.
Quiet, safe and built to last
Every STERR bathroom fan uses a ball-bearing motor for quiet running and a long service life, carries an IP44 rating for use in bathroom zones, and includes a backdraught shutter to stop cold air blowing back in. A two-year warranty comes as standard.
