What Are the Standard Bathroom Stall Dimensions?
The standard bathroom stall size for commercial restrooms follows International Code Council (ICC)/American National Standards Institute (ANSI) A117.1 and International Building Code (IBC) guidelines. Most projects work from three baseline configurations sized for typical adult occupants.
Standard Stall Dimensions
- Width: 36 inches (most common) or up to 60 inches
- Depth: 60 inches from front to rear wall
- Door width: 24 to 32 inches
- Panel height: 55 to 58 inches above finished floor
ADA-Compliant Stall Dimensions
- Width: 60 inches minimum, measured wall-to-wall
- Depth: 56 inches (wall-mounted toilet) or 59 inches (floor-mounted)
- Door width: 32 inches minimum clear opening
- Maneuvering space: per ADA and ICC A117.1 wheelchair accessibility requirements
Ambulatory Stall Dimensions
- Width: typically 35 to 37 inches (Section 604.8.2)
- Depth: 60 inches minimum
- Door width: 32 inches minimum
- Grab bars on both side walls
What Is the Typical Toilet Stall Door Size?
Typical toilet stall door size is 24 inches wide for standard stalls and 32 inches wide (clear opening) for ADA stalls. Doors are manufactured in 1-inch increments, and most projects typically specify a 26-inch outswing door for standard stalls to maximize usable floor space inside the compartment.
How Tall Are Commercial Bathroom Partitions?
Commercial bathroom partitions are typically 58 inches tall and mounted 12 inches above finished floor, producing a 70-inch overall height. Higher-privacy configurations raise this considerably and have grown in specification across healthcare, hospitality, and corporate projects.
Standard floor-anchored/overhead braced: 58 inches tall, 12 inches off floor
Floor-to-ceiling anchored: extends to ceiling, typically 84 to 96 inches
Full-height European style: 80 to 96 inches with minimal sightlines
Maximum privacy configurations: 72 to 120 inches
For projects requiring minimal sightlines, the Alpaco Classic Collection and Maximum Privacy Phenolic partitions use flush-close doors and overlapping panel edges.
What Is the Minimum Restroom Stall Size by Code?
The minimum restroom stall size by code is 36 inches wide for a standard wall-hung stall and 60 inches wide for an ADA wheelchair-accessible stall. The 2021 IBC and ICC A117.1 set these minimums, though California, New York, and several other states enforce larger dimensions.
Common Code References for Specifiers
- 2021 IBC Chapter 29 for plumbing fixture count
- ICC A117.1-2017 Section 604 for toilet compartments
ADA Standards for Accessible Design Section 604.8
- State and local amendments, which typically take precedence
These four references cover most commercial restroom projects in the United States, though specific applicability varies by project type. High-occupancy venues like stadiums, airports, and convention centers may trigger additional fixture requirements from local health departments.
Do Stall Dimensions Change by Mounting Style?
Stall dimensions change slightly by mounting style because pilaster width and hardware offsets differ. Ceiling-hung partitions gain roughly 1 inch of usable stall width since there is no floor-mounted pilaster shoe. Full-height partitions may lose 2 to 3 inches due to extended pilaster shoes. Floor-anchored/overhead braced systems remain the most dimensionally efficient option for typical commercial installations.
ASI Global Partitions offers four mounting styles and configurations that allow specifiers to hit tight dimensional targets. To compare materials across every mounting style, see the ASI Material Selector.
Choosing the Right Stall Size for Your Project
Stall size selection depends on occupancy, code jurisdiction, and privacy expectations. High-traffic public restrooms benefit from wider 36-inch stalls, while healthcare and hospitality facilities often specify full-height privacy partitions to meet user expectations. Most commercial projects mix two to three stall sizes across a single restroom, including at least one ADA-accessible compartment and often one ambulatory stall. Pediatric and elementary school restrooms size down to 30-inch widths with 48-inch panel heights.
For minimal-sightline specifications at any panel height, ASI’s patented Integrated Privacy system reduces door gaps at the factory on stainless steel and powder-coated steel partitions.
