Bathroom Plumbing Rough In Diagram
Get the rough in right and the toilet, sink, and vents line up before drywall, so a bathroom remodel never stalls at the finish stage. ArcSite's bathroom plumbing rough in diagram lays out drain and vent piping for a toilet and sink in one side view.
Key Features
This bathroom plumbing rough in diagram includes:
- Toilet drain running below the floor line
- Wall-mounted sink with a P-trap and two supply stops
- Sink drain tying into the vertical dry vent
- Horizontal dry vent connecting back to the main stack
- Toilet and sink drains joining before the stack
- Fittings drawn at every pipe joint
The sink vent climbs and turns over to the stack well above the basin, which gives you the wall framing height to plan for before the inspector walks the rough in.

Frequently asked questions
Does this diagram include the water supply lines?
Only at the sink, where it shows the two supply stops. Draw the hot and cold supply runs in ArcSite to finish the rough in.
Can I add a tub or shower?
Yes! Drop in a tub or shower and its drain in ArcSite and tie it into the same vent stack.
Does ArcSite work for plumbing contractors?
It does! Rough ins, fixture layouts, drain runs: plumbing contractors draw all of it on a tablet and quote off the drawing.
