I'm putting in a new bathroom in the attic... I have extended an main drain from the basement to about 3 feet from the attic floor. Ceiling is ripped out on floor below. What is the protocol for order of fixtures going into the main drain and where the vents should be. Or what vents are required.

The toilet will connect to the stack with a sanitary tee. The lavatory will connect to the toilets drain line and a vent run out the roof or revented back in the attic and the shower will connect to the lavatory drain and be wet vented by it. Good luck, Tom
