Yes it does, otherwise it will vent in your bathroom and make everything stink. and it is not a very attractive sight to see.
vent in bathroom manditory
NO, just duct it into the soffit. you can also get the indoor kit that is made for a dryer, but at some point you should install a vent to the outside,there are tons of vents.
We had bees coming in through the bathroom vent to the outside. They were bumblebees who were apparently making their nest inside the vent/roof.
no not a good idea you should never have a return in the bathroom or the kitchen the return will recirculate the smell through out the house bathrooms need an isolated vent this keeps the smell outside the house
Building codes require dryers to vent to the outside.
This would not be a good idea because if you get any back draft which is likely when the vent isn't working then you have one smelly bathroom.
No less the $4,700
Yes BUT not an outside wall
Vaseline Petroleum Jelly is found in the bathroom. Vanacof cough suppressant and vent fan also are found in the bathroom.
A vent is non insulated and should be boxed in on the outside of your home. B vent is insulated and can be left exposed,
water vent kit
gas gets trapped in the drainage system if you don't vent it (and you don't want that gas coming back into the bathroom)
