Bathroom Fitting

Bathroom Shower Vent connect to an exhaust in the attic space

Anonymous user 09/03/2024 - 2.46 PM

Hi there, unfortunately this form won't let me attach a photo to this querie. I have a bathroom vent which connects to flexible upvc ducting running in the attic space which is then connected to an exhaust which is screwed to a joist in the middle of my attic space. Can I just connect further ducting to the exhaust motor end (short electric cables connected to motor which doesn't allow for repositioning exhaust) to extend to a roof vent tile. Or will this limit airflow into the exhaust ? I can send a photo of that makes it easier to visualise. Best Regards Lorraine

Hi I would go for a new install. A bathroom vent shouldn't terminate inside your loft as this will cause damp. Warm vapors need to go somewhere and they are currently condensing on the inside of your roof. I find expelair fans do the job!

Hi, this is very difficult to provide detailed information without photo's etc. However, I would advise the shortest pipe run possible using insulated pipe. Yes then as in your question, the pipe would run from the bathroom ceiling port to the inlet side of the 'inline' fan, then insulated pipe from the outlet side of the fan to a roof tile vent. I would keep the roof tile vent quite low to aid maximum extraction of moist air to the outside atmosphere. Keeping the pipe run low & short aids the fan moving the moist air through with least restriction. I use Manrose inline fans, as they are reasonably quiet, yet very powerful & reliable. Hope this helps. Jayson.
