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?

Thanks in advance.

It was not practical for me to go through the eaves, so I purchased a
vent which replaced a couple tiles, and easy job. Works fine

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.

I had a look at the outside of the house and I don't appear to have any
eaves! Any advice on how I could vent the thing?

I'm thinking it may be easier to just replace the original wall mounted one
with with a more slim line unit. The hole at the moment is approx 12cm which
is just over inches. Looking at TLC Direct etc looks like most of the fans
are around inch and they look a lot more slimline than this archaic unit!

It is acceptable to seal the back plate of the fan onto the wall with some
silicon to give it a good seal? Is that the way to do it or can I just screw
the thing onto the wall?

Tile vent might work then...

Might be OK - where is the fan in relation to the shower?

They usually just screw to the wall... (often you screw a detachable
backplate to the fan on first, wire it up, and then fix the fan to it)

That's the problem, its diagonally opposite to the shower around 2 metres
away. I think its better to have one above the shower.

Not that difficult - but it helps if you can get to the outside of the
roof in the right position.

I was actually asking the question from a slightly different
viewpoint... in that electrical accessories sited above a shower or bath
are subject to more stringent requirements in the wiring regs than those
which are further away. There is some more detailed information he-

Having an extractor the other side of the room will still make a big
difference compared to having none at all, although it may not be quite
as effective as an extractor directly over the shower.

Hi, I planned to get one where the actually motor/fan was situated in the
loft with just the ducting above the shower. I believe that these are safe
to use over showers.

I think I'll just replace the current wall one with a new model as I don't
have the guts to get onto the roof!!!

Yes you are right - the ducted ones are OK. I was just checking that the
current wall mounted one was not right over the shower.

If you position the vent near to the edge of the roof (say 3 or 4 tiles
back) then you can do it all from a ladder without any need to get on
the roof.

Having said that you will probably find the "through wall" one is good
enough. I fitted one of these myself recently. It is in the oposite
corner of the room from the shower, but is still able to clear the
visible steam in a couple of minutes of the shower being turned off. On
humid days like we are having at the moment, it will run on for a couple
of hours after as the humidity comes down though. It is quiet enough to
not be intrusive though. The unit is a 4" one with built in humidistat
that I got from Screwfix.
