Vent options for basement dryer & bath
Adding a basement bathroom and laundry center with a gas dryer. This is a walkout basement with a deck over the area the bathroom is located. Originally the plumber thought the gas dryer vent and bathroom exhaust fan vent would go out above the foundation wall and through the deck ledger however there isn't enough clearance. He thinks the only option now is to go through the 8-10" poured concrete. This will be very expensive if it needs to be bored through. Any ideas or experiences as well as a cost estimate for the boring would be helpful. He thinks he maybe able to use a large hammer drill to cut the hole but he needs to check. I'm in Northeastern CT.
