Kleva was suggesting outside Zone 3 which would be 3.6m from shower. I would install a diffuser and some flexible duct in the shower itself and fit an inline fan in the roof space somewhere outside Zone 1 &2 with a 2 or 3-pole isolater depending on the type of fan and also RCD protection and a discharge louvre through the outside wall. This would depend what is above your bathroom ceiling hence my earlier question.
