Adding a master bath to a 3rd floor.
No shared vent from the rest of the house.
I am in Michigan
2 questions.
1. Do I need the 2" dotted line vent for the shower in the 1st attached picture? Or is it ok to wet vent to the 2" vent downstream from the WC?
2. I can also attach the WC downstream and wet vent both the shower and WC via the double lav as show in the second picture. Is this a better/worse option?
Any input is greatly appreciated
