Hello, I am currently in the process of converting a granny flat with my own labor. Regarding the ventilation of the windowless bathroom and the adjacent separate WC, some unexpected problems have now arisen. Therefore, I hope someone can give me tips and advice on how I might proceed. The ventilation of the bathroom (approx. 6 sqm) and WC (approx. 3 sqm) should also include a kitchen extractor hood. The house is an old building. Unfortunately, I cannot take the direct short route to the parallel outer wall for possible ventilation because a load-bearing ceiling beam runs through the ceiling. A roof ventilation is also not possible, as there is still an apartment on the upper floor. Due to a low installation height, I can probably accommodate only a flat duct system in the ceiling. The total length to a possible wall outlet is approx. 8 meters (if possible, but perhaps dispensable, I could install a 90° branch at the end). Now my questions: Which fans could I use (if I can install the fan at the end of the system, a larger diameter and the installation of a round duct might also be possible there)? Is it possible and sensible to use T-pieces to integrate the three ventilation points? How can the fan be switched on? I would be very happy if someone could help me solve my problem. If necessary, I can also send an illustrative drawing.

I do not think it is a good idea to route the exhaust air of the range hood through the bathroom ventilation. The long exhaust path alone would not be good and would require an external motor for proper use of the range hood.

Please upload the complete floor plan including windows and information on whether the exterior walls are entirely underground or maybe still exposed.
