I am replacing the extractor fane in a (very) small ensuite bathroom (1.75m x 1.45m).
After removing the current (very noisy) fan I see it has a 6 inch vent. The fan I bough to replace it has a 4 inch vent.
Rather than fill the 6 inch hole up, wait for it to dry and then drill a 4 inch hole, can anyone suggest a good way of reducing the 6 inch hole to 4 inch (and in such a way that would give something for the new fan to screw onto)
thanks
