I am installing an en-suite shower room in a loft conversion & need to find an extractor fan which can fit through the sloping tiled roof. Does anyone know how this can be done & who supplies suitable fans / external fitting for the roof ?

This site looks interesting. Particularly thier "In-line Slate Ventilator"

Alternatively, you could try one of these at the ridge line.
I often wondered where does the condensation go on the internal ducting ? My extractor ducting is flat on top of ceiling and out to the soffit vent but I bet there's some water puddle there.

I would suggest some extractor fans. Timed fans in the bathroom or toilet are activated by the lightswitch and are particularly useful when these rooms don't have external walls. Obviously, they will require ducting to enable the air to be expelled outside, but the timed switch poses no extra problems as it's connected up to the light switch when the fan is linked to the lighting circuit. Ceiling-fitted extractor fans are also available. They require an unobstructed space of 300mm between ceiling joists, and may also require ducting to an external wall if you have glass fiber roof insulation.
