What bathroom ventilation includes
-
Duct inspection
We check the existing shared shaft or duct and whether it actually draws air.
-
Quiet extractor fan
A low-noise unit with airflow matched to the size of the bathroom.
-
Timer or humidistat
Runs on after the light goes off, or starts by itself when humidity rises.
-
Ducted outside
Ducting to the façade, light well or roof when there is no usable shaft.
-
Electrical connection
A protected supply kept out of the wet zones, in line with the REBT.
-
Air inlet
A gap under the door or a grille so fresh air can actually come in.
Ventilating a bathroom in Cerdanyola del Vallès: what we check first
In houses and terraced homes in areas such as Centre, Serraparera and Fontetes, upstairs bathrooms are often under the roof. We take the duct up to a vent tile or cowl on the roof, and on the ground floor we find the shortest route to the façade.
A fan with no air coming in barely moves anything. In bathrooms in areas such as Banús, Turonet and Guiera, we trim the door or fit a transfer grille and, at the end, check with the door shut that the fan is really pulling.
After the visit you receive a detailed written quote setting out the duct route and the type of fan. We also ventilate bathrooms in nearby areas: Sabadell, Sant Cugat del Vallès and Ripollet.

Frequently asked questions
01Bathroom ventilation in Cerdanyola del Vallès: which areas do you cover?
We do this work in Cerdanyola del Vallès, in areas such as Centre, Serraparera, Fontetes, Canaletes, Banús, Turonet, Guiera and Can Xarau, and also nearby: Sabadell, Sant Cugat del Vallès and Ripollet. Before starting we visit the property and prepare a detailed written quote.
02Can the bathroom fan share the kitchen extract duct?
No. Each needs its own duct: sharing one lets cooking fumes and smells into the bathroom, and the CTE (DB HS 3) rules it out.
03Timer or humidity sensor: which is more suitable?
A timer is simple and enough for most bathrooms. A humidistat suits internal or heavily used bathrooms, as it only kicks in when there is steam.
04What if the building's shared shaft does not draw?
We check whether it is blocked or shared with other flats. Sometimes the right fan is enough; if not, we look at a dedicated outlet to the façade or light well.
