    Hi everyone. I am converting my garage into a a master bedroom with a bathroom. I am looking for help on my venting setup. My town in Arizona uses the ipc code if that helps. So if you look at the picture I plan to run a 3” from the toilet to the main line and a 1 1/2” vent, the the tub will also get a 1 1/2” vent, the the dual vanity will also get a 1 1/2” vent. Will that be enough? Also does the stand up shower need a vent? Thank you. I’m a diy and need some guidance.

    All drains need their own vent (stand up shower). I'd say check with the local codes as they will vary. For instance, they told me to use 3" vents. The reason being we live in a cold climate, so the 3" is to avoid the vent frosting up. Not applicable in AZ, but you can see there's no 1 size fits all.

    I think the vents are the little white circle in the nearest wall at each fixture.

    I was going by what he wrote, wondering about a shower vent, but didn't look at the drawing.

    We would allow 4 1/2" for rough framing of wall inside a tall foundation wall. Not sure if that applies here.
