Bathroom Drain Vent Layout
A drain vent layout has to show where every fixture connects to a vent, not just a drain, since a fixture without proper venting can siphon and cause drainage problems. ArcSite's bathroom drain vent layout lays that routing out, ready to adjust to a specific bathroom.

Key Features
This bathroom drain vent layout includes
- Toilet, sink, and bathtub drain and vent connections
- Color-coded pipes (red for drain, blue for vent)
- Toilet vent connection into the main stack
- Shared vent for sink and bathtub
- Vented tee-wye configuration
- Accessible cleanouts
The sink and bathtub share one vent rather than running separate vent lines, worth keeping since that's what keeps the pipe count down without sacrificing flow.

Key Considerations When Designing a Bathroom Drain Vent Layout
Every fixture needs its own vent connection to prevent siphoning, and cleanouts have to stay accessible for future maintenance, which is where a lot of retrofit plumbing runs into trouble. In ArcSite, you can mark up this drain vent layout with your own fixture and vent routing for the bathroom you're working on.
