  • pedestal or vanity cabinets with a middle obstruction
  • small items that can live around plumbing

Measure before choosing this role

  • pipe centerline width
  • left-side usable width
  • right-side usable width
  • clearance below the trap

Avoid this role if

  • the pipe shape is offset and wide
  • you need one full flat shelf
  • cabinet height under the pipe is very low

Common mistakes

  • assuming one U-shape fits all plumbing
  • ignoring shutoff valve access
  • using tall bottles where the pipe drops low

Likely failure modes

  • pipe opening is too narrow or too wide
  • back row becomes dead space
  • organizer blocks valves or disposal lines
