Small Shower Room Ventilation.

I was talking to a developer this morning. His son is a sparks. The two have installed a new 4 inch ceiling fan in a small upstairs shower room that has no windows. The building roof has been renewed recently and new breathable "felt" installed under the tiles. I had previously mentioned that the roofers could install a new roof vent for the fan ducting, but nothing has been done about this.


The developer says that the son advises terminating the air duct in the loft onto a bucket to catch moisture, which I said was not acceptable.


Bearing in mind that the new roofing "felt" (membrane) is breathable, is there any reason these days not to terminate the air duct directly into the loft space with no external grille?

  • Yes, for a tumble the instructions say you must rinse it out after each use, and re-prime it with cold water before use, it is not really the right thing in a bathroom.

    I bet loads  of folk do not clean them out, and they end up with a load of mouldy fluff and damp air in the house. A hole and some 4 inch pipe is far less likely to go wrong and give you long term heath issues ( NHS page on nasty things damp and mould can do to you. )
