I intend to fit a new extractor fan above my shower. This will be the type
with ducting that ducts the extracted air through the loft and out of a vent
in the eaves of the house.

How easy are these to fit? Can anyone give me a quick summary of what's
involved?

Cut a hole in the ceiling above the shower to match the vent plate
(plasterboard pad saw will probably do it). Make sure you check where
the joists are before you start cutting! You may need to adjust the
poistion of the inlet so you can miss the joists.

Fit the plate - silicone it in place so there is no possibility of water
or spray making its way to the cut edge of the plasterboard under the
flange at the edge of the vent.

Fit the extractor in the loft, connect the duct from the shower vent to
the extractor.

Now cut a hole in the eves - exactly how will depend on what your eves
are made of - post back with more info and we can advise. Fit the vent
there as per the shower one. Connect duct back to extractor.

Now set about wiring it. How will depend a bit on the type of fan. The
best option may be one with a humidistat. You can power it from a
lighting circuit if you want (if you want the type that comes on when
you turn the light on, then it must be powered from the lighting
circuit. Make sure you use a 3A fused connection unit to supply power,
and also include a fan isolater switch. The switch can be in the
bathroom if it is a pull type, or alternatively, mount a conventional
plate switch type isolater outside the bathroom.
