Apart from the VMC, is there another way to quickly remove the bad smells of toilets? I have normal small ventilation and no window of course.
There are point ventilation systems for rooms without openings. These are independent electric extractors, the most common of which are centrifugal extractors which have a propeller motor. When buying, check that the flow of the machine corresponds to the volume of your toilet. An extractor can be installed at the top of the wall if it gives directly to the outside. Otherwise it will be connected by a conduit to an exit on the roof. An air intake should be created in the nearest room for the system to be effective.
