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.
