Bathroom ventilation in Sant Just Desvern.
In Sant Just Desvern we sort out windowless bathrooms and those with a small window that never dry: fan, duct and air supply planned together.

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.
Bathrooms in Sant Just Desvern: why the steam and mould stay
In areas such as El Poble, El Raval and La Carretera, where winters are cold, hardly anyone opens the bathroom window after a shower and steam condenses on the outside wall. A fan with an overrun timer removes it without chilling the house, and we insulate the duct where it crosses cold spaces.
For ducting in bathrooms in areas such as La Muntanya, Mas Lluí and Can Modolell, we use smooth rigid pipe rather than corrugated flexible hose, on the shortest route through the false ceiling and with a slight fall outwards so condensation does not run back into the fan.
With over 20 years renovating bathrooms we know where ventilation tends to fail; we spot it on the visit and set it out in a written quote. We also work nearby: Esplugues de Llobregat, Sant Joan Despí and Sant Feliu de Llobregat.

Frequently asked questions
01Bathroom ventilation in Sant Just Desvern: which areas do you cover?
We do this work in Sant Just Desvern, in areas such as El Poble, El Raval, La Carretera, La Muntanya, Mas Lluí and Can Modolell, and also nearby: Esplugues de Llobregat, Sant Joan Despí and Sant Feliu de Llobregat. 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.
