Getting your commercial restroom layout right sets the stage for a smooth, efficient installation! When you hit the exact space requirements for each stall, inspections are a breeze, panel orders go through without a hitch, and your project stays right on schedule.
This guide delivers precise, reliable bathroom stall dimensions for standard, ADA wheelchair-accessible, and ambulatory compartments—sourced directly from the 2010 ADA Standards and trusted manufacturer spec sheets. You’ll also get essential layout insights that make planning effortless, including how to properly measure a 60-inch clear compartment for actual floor space, and exactly what to verify before placing your order so your install goes perfectly the first time.
In the following sections, you will find:
- Standard stall dimensions used across commercial construction
- ADA wheelchair accessible and ambulatory compartment requirements
- The difference between clear dimensions and nominal layout numbers
- A field measuring checklist for ordering toilet partitions without rework
Standard Bathroom Stall Dimensions
A standard commercial toilet stall measures 36 inches wide by 60 inches deep with a 24 inch inswing door. Doors and panels run 58 inches high and mount 12 inches off the finished floor. Hadrian publishes 58 inch high doors and panels mounted 12 inches above the finished floor across its standard series. Bobrick lists the same 58 inch door height, with inswing doors standard on 22 inch to 37 inch openings.
Width has some flexibility on non-accessible stalls. Plumbing codes require at least 15 inches from the water closet centerline to any side wall or partition, plus 21 inches of clear space in front of the bowl. In practice, 36 inches remains the working standard because anything narrower feels cramped and complicates hardware placement.
Depth follows the fixture. A 60 inch deep stall fits nearly every commercial water closet while preserving the required front clearance. Tighter footprints exist in renovation work, though each one needs a code check before you commit to panel sizes.
ADA Wheelchair Accessible Stall Dimensions
The 2010 ADA Standards set hard minimums for at least one wheelchair accessible compartment in every multi-stall restroom. These numbers come from Section 604.8.1 and the US Access Board’s technical guide:
- Width: 60 inches minimum, measured between finished surfaces
- Depth: 56 inches minimum with a wall mounted toilet, 59 inches minimum with a floor mounted toilet
- Door: 32 inches of clear opening minimum, self closing, swinging outward, never into the minimum compartment area
- Toilet centerline: 16 to 18 inches from the side wall. The Access Board recommends specifying 17 inches to absorb construction variation of up to 1 inch
- Grab bars: 42 inch minimum side bar and 36 inch minimum rear bar, both mounted 33 to 36 inches above the floor
- Toe clearance: 9 inches high and 6 inches deep minimum under the front partition and one side partition
The toe clearance rule catches a lot of projects. Specify full height privacy panels or floor anchored shoes without toe space and the compartment must grow: 66 inches wide minimum without side toe clearance, and 62 inches deep (wall mounted) or 65 inches deep (floor mounted) without front toe clearance. Privacy upgrades change the footprint, so lock this down at the drawing stage, not during install.

Ambulatory Accessible Stall Dimensions
Restrooms with six or more toilet compartments, or a combined total of six or more toilets and urinals, need at least one ambulatory accessible compartment on top of the wheelchair accessible one. This requirement in Section 213.3.1 gets skipped in more layouts than any other, and inspectors look for exactly this stall.
Ambulatory compartments serve people who use canes, crutches, or walkers. The dimensions are precise:
- Width: 35 to 37 inches. This is a range, not a minimum. A 60 inch wide ambulatory stall fails because the user needs both grab bars within reach
- Depth: 60 inches minimum
- Door: 32 inch clear opening, self closing, swinging outward
- Toilet centerline: 17 to 19 inches from the side partition
- Grab bars: both sides, mounted 33 to 36 inches above the floor
Stall Dimensions Compared
| Stall type | Width | Depth | Door | Key extras |
|---|---|---|---|---|
| Standard | 36 in typical | 60 in typical | 24 in, inswing | 58 in panels, 12 in floor gap |
| ADA wheelchair | 60 in min clear | 56 in (wall WC) or 59 in (floor WC) | 32 in clear, outswing, self closing | Toe clearance 9 in high or larger footprint |
| ADA no toe clearance | 66 in min | 62 in (wall WC) or 65 in (floor WC) | 32 in clear, outswing | Applies with full height privacy panels |
| Ambulatory | 35 to 37 in | 60 in min | 32 in clear, outswing | Grab bars both sides, needed at 6+ fixtures |
Clear Dimensions vs Layout Dimensions
Here’s the trap in every set of stall numbers: code measures the clear inside dimension between finished surfaces. Your floor plan measures wall to wall. Those are different numbers.
Three 36 inch stalls need more than 108 inches of wall run. Pilasters sit between compartments, panels have thickness, and walls are never perfectly plumb. Tile, cove base, and furring eat more space. Plan the run with the pilaster and panel dimensions from your manufacturer’s shop drawings, then confirm the accessible compartment still nets a true 60 inches clear.
The door rule works the same way. ADA requires a 32 inch clear opening, not a 32 inch door. Hinges, strike hardware, and the door slab itself reduce the opening when the door sits at 90 degrees. Specifying a 34 or 36 inch door leaf is the reliable way to guarantee a 32 inch clear passage.
How Mounting Style and Material Affect Your Numbers
Mounting style changes pilaster heights and floor conditions. Overhead braced systems run a continuous headrail with 82 inch pilasters. Floor to ceiling and ceiling hung systems need structural support above the finished ceiling and change the toe clearance picture. Floor mounted systems anchor into the slab, so slab thickness and embedded utilities matter.
Material changes panel thickness and hardware spacing. Powder coated steel, stainless steel, solid plastic HDPE, phenolic black core, and plastic laminate each carry their own panel thickness and edge detail. The differences look small on paper and add up across a six stall run. Pull the spec sheet for your chosen material before finalizing the layout.
Measure Before You Order
Field verification prevents nearly every partition ordering error. Walk the room with a tape and record:
- Wall to wall width at three heights, since walls bow
- Depth from the back wall to the front of the stall line
- Toilet centerline distance from each side wall
- Floor slope toward drains
- Ceiling height and structure, for ceiling hung or floor to ceiling systems
- Locations of columns, chases, and plumbing cleanouts
Bring these numbers to your order. Our team checks them against the compartment minimums above before anything goes into production, which is how you avoid field cutting factory finished panels.
Frequently Asked Questions
What is the standard size of a commercial bathroom stall?
The standard commercial stall is 36 inches wide and 60 inches deep with a 24 inch door. Panels and doors are 58 inches high, mounted 12 inches above the finished floor.
What are ADA bathroom stall dimensions?
An ADA wheelchair accessible compartment is 60 inches wide minimum, 56 inches deep with a wall mounted toilet or 59 inches deep with a floor mounted toilet, with a 32 inch clear outswing door opening.
When does a restroom need an ambulatory accessible stall?
Whenever the room has six or more toilet compartments, or six or more total toilets and urinals combined. The ambulatory stall is 35 to 37 inches wide and at least 60 inches deep with grab bars on both sides.
Is a 30 inch wide bathroom stall allowed?
Only on non-accessible stalls, and only barely. Plumbing codes require 15 inches from the toilet centerline to each side, which makes 30 inches the absolute floor. Most projects spec 36 inches for comfort and hardware fit.
How tall are bathroom stall partitions?
Standard doors and panels are 58 inches high and sit 12 inches off the floor, for roughly 70 inches of total height. Taller privacy panels and full height options exist, and full height designs change ADA footprint requirements.
Why is there a gap under bathroom stalls?
The 12 inch gap supports cleaning access, air circulation, and the 9 inch toe clearance the ADA requires under accessible compartment partitions. Reduced sightline and extended height panels shrink the visual gap while keeping code clearances.
