Toilet extraction fan required?

[Andystraughan]

On a house refurb at the minute and the joiner (who knows it all) is insisting that the downstairs loo requires a extraction fan. Its a tiny room toilet and sink. No windows and approx 3 metre away from any outside wall.

there is an extraction fan going in the up stairs ensuite and main bathroom which both have showers

is is this required?

any advice or a link to the correct building regs would be greatly appreciated

Ask yourself this first. "would you have a dump in there and then 5 mins later let a visitor use the loo after" answers on the back of a postage stamp please.

 

[telectrix]

if the home owner wants a fan, he gets a fan. there is no regulation saying you have to fit one in a toilet. tell the joiner to stick to butchering wood.

 

[MDJ]

No regulation as such, but the building inspector still may ask for one, that said anyone having a dump in there may feel afterwards they wish a fan was installed, too many rules and regs which are total rollocks IMO, get a fan in there now before everything is decorated.

 

[Andystraughan]

Ok will do. Thanks guys

 

[MDJ]

You Northerners are dirty little b*ggers arn't you? do you wash your hands after a dump up there? LOL

 

[telectrix]

agree ^^^. best to fit one, but obviously discuss with client ( and building inspector if he's involved ) beforehand.

 

[Octopus]

Common sense & good practice says fit one. oh and ask the fitter for the building reg to justify his position!

us northerners use toilet paper, not our hands like southern -------. lol.

Having a fan installed would create negative pressure and not allow the stench of your dump to escape the room, ie air and therefore smells as well enters the room vie gaps under door etc but exits via fan.

??? If air is entering the room (eg under the door) and exiting through fan, how will it not allow smell to escape?

Sry I ment escape into the rest of the house ie air is traveling into to toilet though the gaps under so the smell can't get through that way as scent is carried by air! So the smell can only leave the room via the fan!

Thought it was in the building regs that if there was no form of natural ventilation fitted (ie a window that opens) then some sort of mechanical ventilation had to be installed (eg a fan)

put it this way ian, only dirty b&ggers would not consider some kind of ventilation in a very small toilet in the middle of a house with no window lol

Cutting half an inch off the bottom of the door is usually a tidier way of achieving the same result.

Since when has anyone been allowed to take a dump in the downstairs toilet?! That was (probably still is) a thrashing offence according to my old mum!

To get the fan to work best you need to allow air to enter the room for the fan to expel to the outside.

Fit the fan on the opposite wall to the bog door and fit the bog door making sure it swings open & shut freely.

Start the fan and slowly close the door until you feel the suction of the fan pulling the door shut.

At this point, measure the gap between edge of door and the door frame length x width and calculate the area of this gap. This is the size of the vent to fit into the door at a low level.

connect the ductwork from the fart fan to the furnace burner air intake.
take advantage of the free fuel

All rooms have reasonable ventilation otherwise you would head into the loo with your sun newspaper and by the time you got to Dear Deidre. You would have suffocated.

I agree, but here we're not talking about adventitious ventilation - we're talking about having the right amount of airflow to make the fan work as it should, and that little bit of info. I posted is not a figment of my imagination either.

 

[Octopus]

or provide the customer with a scented candle, candle holder and packet of matches! lol

Think I would have better use for that paper than reading it and being in the toilet should give a clue

i dont know! with some serious farts and matches they may end up calling the fire brigade

 

[Darkwood]

You Northerners are dirty little b*ggers arn't you? do you wash your hands after a dump up there? LOL

Hey i still own an outside loo ... i call it the curry rescue center ...no need for ventilation out there just a seat warmer :-------:

 

[Andy78]

Just provide a sign on the inside of the door.

" All odours must be inhaled fully by the offender before leaving the privvy "
