Placement of bath fan

Can i place a bathroom exhaust fan in the shower ceiling? The ceiling is 8 feet tall in the shower stall.
Thank for your help...

Re: Placement of bath fan

We have our fan in the ceiling of our shower stall. I think it depends on the fan. The fan you select should note whether or not it is right for installation in a shower stall.

Yes it can.
Remember though vent fans installed directly above showers must be GFCI protected.

Same topic - different question. I have two bathrooms that share a common wall. Can I gang the fans on the same exhaust to the outside world?

Good question. Odds are that both fans would not be in use at the same time. But if they were, and certainly could be, would the duct work handle the double air flow. Since there is little if no resistance other than a flapper, methinks the size of the ductwork could handle the flow. But I could be wrong. Boy, was that last sentence difficult to type.
Any code sleuth's out there?

No you may not. The listing requires dedicated exhaust ducting to the outdoors, as do the model codes. Spread of fire, draft blocking, etc.

Many times bath exhaust vents will be tied together into a central system.

If you are using two individual exhaust fans and would like to use a common duct then you need to ensure the fans have backdraft dampers and the duct size is a minimum the same volume as a 4 inch --- preferably larger --- so as to have minimum static pressure in the event both are running at the same time.

Otherwise you could have one large inline fan with a " T " running to vent grills in each bathroom .
