Hi, hoping this has probably been done many times and someone will have
a quick answer

I am just finishing off an extension which has left me with a
bathroom in the middle of the house with no external walls, so no
windows.

Can anyone suggest an extractor fan that would be suitable and upto the
job
of keeping the bathroom relatively dry from the steam.

Extractor will be vented through the roof

The other qestion is, are 18mm water resisitant Tongue & Cheek chipboard
panels
suitable for 1st flooring (especially in a shower room)

Thanks in advance for your responses

Water resistant chipboard!!. Interesting.

I after a leak or two and replaced with 18mm Marine ply flooring, will take
a soaking apparently.

any tangential fan designed to be used with ducting. See screwfix or
toolstation .com
4" will give you garbage flow rate, 6" has real use.

TLC also do a 5" wall mounted one - installed two of those in the past. The
one in our shower room works like a dream - never a trace of any steam in
the room (timer set to 10 minutes or so).

Thanks for the replies

Looks like my options are either 18mm wbp plywood or aqua panels over
the top of the chipboard that
has already been laid.

BTW, is the chipboard ok for other rooms like bedrooms, or a definite
no-no and just stick to 12mm
wbp plywood for these.

Thanks

According to building regs it is:

Still, I'd seal it with a couple of coats of something decent like
marine varnish and tape the joins with aluminium tape. If you can
seal the edges too and a border round the underside before laying even
better.

Whatever you use if it stays wet for a long time it will rot unless
treated, so sealing is a good way to go.

If tiling on it check with adhesive manufacturer for compatiblity with
your sealer of choice.

cheers,
Pete.

chip is fine where theres no chance of it getting wet. Water only needs
to sit on it once and its a gonner, so quite uselses for bathroom
floors.

The water resistant chipboard for bathrooms survives wet for ages,
much to my surprise. Things like the carpet grippers had all rotted
away, but the chipboard was still rock solid, in spite of being wet
possibly for a year or more, and supporting an internal thermal
block wall (also wet right through).

Standard chipboard flooring disintegrates as you suggests.

Ooh. This sounds like what I've been looking for for ages. Well, it
would if it comes in a melamine finished version, but I dont suppose
flooring does.

Sounds good, did it warp or expand much?

I suppose a good test for flooring chipboard is to boil a sample or
give it a cycle in an old dishwasher.

Not at all. I was worried about the wall built on it dropping,
but it hadn't. I don't know if there are different qualities
of waterproof chipboard. I think the whole upstairs floor of
this house (about 15 years old) is built with it.

That sort of heat might have other effects.
Just leave a piece outdoors and see what happens.

Seems to be a valid way of testing moisture resistance:

If using it for a project then a quick test would be helpful, though
buying it from a reputable source should be a good start.

cheers,
Pete.

I agree.
Just out of laziness I have had an old sheet of green 18mm chip outside
for the last 3 weeks Of which one weekend was the wettest I have seen
for years. It's resting between the angled drive and the flat flag
stones, and gets used as a spring board on a daily basis.

So far it is holding it's own. has a slight curvature, but no more than
the new stuff I got off Wicks shelves last weekend!
