Bathroom extraction with no provision for outlet

[stevethesparks]

Hi
Have quoted for multiple ensuites and bathroom additions for an old customer. I did include in my quotation that any coring or ducting for extraction fans to be undertaken by the builder - so I am covered.
However, the builder is a mate, and I'd like to help where I can.
There is one small ensuite on a mid floor in the centre of the house that is proving difficult to route a suitable ducting, and even where possible ends up above a conservatory.
I feel a little dumb even asking, but is anyone aware of any such device that could be used to direct the extract fan through that would send any humidity to a local soil pipe or similar?
Any suggestions appreciated.

The only plans I've seen are on a sheet of A4 in pen
There is no extension or new build just conversions of existing vacant rooms.

In this instance its just a 1st floor bedroom they want to put a loo and shower into, but do not want any ducting/boxing in through the bedroom.
Due to the soil pipe, entry door and window locations, it wouldn't be possible to shift the ensuite to the outside wall either.
They could have just had an open shower in the bedroom, but wanted a toilet too.

This is what really frustrates me with some customers, they want something particular then put restrictions on how it can be done making the job virtually impossible. Had one a while back who wanted a couple of extra sockets, but no surface wiring and no chasing. I said wireless sockets are yet to be invented.

There is a 4" vent kit you can get where you core your hole from the inside then pass the duct and grill through the hole and the grill is sprung loaded or something and you pull it back and it pings open on the outside for when there is no access! I have no idea what its called but i know it exists and would probably solve your problem! You'll have to have a google

I may not be in the correct area but could the builder not get his scaffolding contractor to erect a stage over the conservatory which you can use to do the external works.

 

[stevethesparks]

He could, but the customer doesnt want that sort of expense. Scaffolding has been up in the past, and these works are extras. It would be quite an expense just to get a ducting outside.

Nobody wants to pay 'just to get ducting outside but I'm sure they want the job signed off so something will have to give

There are 2 units I'm aware of that can be installed from "inside" a building and thus avoiding going up ladders:

Vent Axia Quick Fix Termination 100mm (565535) which I've used on a few occassions.

or

Manrose Deluxe Quick Internal Fit Wall Kit - 4 Inch Brown - https://www.tlc-direct.co.uk/Products/FDQWK4B.html?ad_position=1o1&source=adwords&ad_id=45425533757&placement=&kw=&network=g&matchtype=&ad_type=pla&product_id=FDQ

which I've not used as yet.

If it can be cut out from inside then I think that's the only option you've got as any other alternative your coming up with opposition as Dave OCD posted.

 

[stevethesparks]

Many thanks all. I've just emailed the builder with some idea's, I'll see how he responds.
It wouldn't meet with building regs but I wonder how effective a wall mounted bathroom dehumidifier would be?
Alternative, install the shower for cold showers only

Ive used both them kits and there are others on the market and they work fine, but coring a hole above the conservatory!! no thanks.

Does the soil pipe not vent to free air at the top? can you not install a 110mm rigid duct along side it, up-rate the fan and fit a condense trap?

Unfortunately not
The soil pipe goes into a smaller pipe above and then into a loft mounted durgo.
