Tips and Tricks: Measuring for your bathroom stalls

Minimum Compartment Depth – Inswing Door

  • Standard rule for inswing doors is to add 30’’ (distance from back wall to front of toilet) plus door opening size (edge to edge). This is the minimum toilet compartment depth required for the door to swing into compartment without hitting the toilet.
  • If compartment is too shallow, you need to increase compartment depth or change to an outswing door.

Measurement Conventions

  • Compartment widths are wall to wall; wall to centerline of panel; centerline of panel to centerline of panel.
  • Compartment depths are back wall to outside (front edge) of stile.
  • Door opening size – edge to edge

Ceiling Height

  • Elevation for overhead-braced toilet compartments is 85’’ from finished floor to top headrail – you will need to ensure ceiling height at least 88’’or higher.
  • For ceiling-hung or floor-to-ceiling anchored stiles, you will need to measure ceiling heights from finished floor to finished ceiling.
  • If floor slopes more than 1’’ across front of compartments, provide finished floor-to-ceiling measurements at each stile location in layout.

Wall-to-Wall Measurements

  • When toilet partitions are recessed between two building walls, the critical measurement is the smallest space between the two walls.
  • Measure wall-to-wall dimensions along the line of the stiles and doors in the toilet compartment (the front)

Room treatments that will affect measurement will be:


  • Tile base cove molding
  •  Wainscoting or decorative trim
  •  Wood or other thick baseboard applications
  •  Half-wall tile
  •  If there are existing wall treatments, measure smallest distance (i.e. baseboard to baseboard), note on drawings, and request gaps between stile and wall be kept to a minimum (1/2” is minimum gap, 1” is maximum).

Existing partition configuration and materials

Note existing material, color and condition of partitions

Try to match existing components and locations where possible – this reducing the amount of “patch and match” required to fill wall brackets and floor anchor holes

Other building conditions that cause problems

  • Baseboard heaters                        
  • Drains
  • Plumbing / pipe runs
  • Windows
  • Support beams
  • Dropped ceilings
