The fan is only half the story
The other half is the duct it plugs into and where the fresh air comes from. Older Warsaw blocks mostly have passive ventilation: a grille into a vertical shaft, nothing more. A fan on that shaft helps, but if the shaft is blocked or shared with neighbours, the result can be weak. And a door with no gap underneath chokes the whole thing, because air has nowhere to come in from.
Airflow is matched to the volume of the room. Bigger isn’t better here: a powerful fan in a small bathroom with a narrow duct mainly adds noise.
AirRoxy has basic models and versions with a timer or a humidity sensor. Those usually need a permanent live feed as well as the switched wire from the light, so three cores at the fan. If the wall only has two, a cable has to be run. Better to find that out before you buy.

Where it tends to go wrong
- The fan ends up right by the door, pulling air from the hallway while the steam stays over the bath.
- No suitable IP rating for a spot directly above the bath or shower.
- A humidity model wired to the light switch only, so it works when the light is on and not when the room is still wet.
- Replacing the fan when the real problem is a clogged duct. New fan, same stuffy air.
If the old fan is loud because of dust on the blades, a clean may be enough. Grinding bearings or a motor that barely turns are a different story, and replacing it usually makes more sense.
A fan on its own won’t fix everything. How to get air moving through the whole flat is covered in our guide to ventilation and damp.
AirRoxy bathroom fan installation: getting ready
- Take a photo of the grille or the old fan, plus the opening behind it.
- Measure the opening if you already have a model in mind.
- Decide how it should run: with the light, on a timer, or by humidity.
- Make sure the fuse box is easy to reach.
Booking it
Describe the job in the app and add photos of the grille and the spot where the fan should go. Handymen reply with their own price, and you compare offers, ratings and reviews before picking one. Only the person you choose sees your phone number and address. You pay them directly, and the invoice comes from them too.
Fixings are normally part of the job. The fan itself, cable and duct fittings are extra, and so is taking the old unit away.
This is electrical work. The circuit has to be switched off at the fuse box before the old fan comes down, and bathrooms have their own rules on zones and power supply.
Order in the app
Describe the job, add photos and the address. Tradespeople send their own prices and dates, and you pick one of the offers.
