ADA Shower Compliance
When ADA-accessible shower facilities are required, what makes a shower trailer ADA-compliant, and which Stahla products meet accessibility standards.

When Are ADA-Accessible Shower Units Required?
The Americans with Disabilities Act (ADA) requires accessible facilities whenever a job site has employees or visitors with disabilities, or when the site is open to the public. For shower facilities specifically:
- Construction sites with disabled workers: Employers must provide accessible shower facilities when any employee on site has a disability requiring accommodation and showers are provided for the workforce
- Public events and gatherings: Any event open to the public (festivals, fairs, outdoor sporting events) that provides shower facilities must include ADA-compliant units as part of the total count
- Government and military projects: Federal, state, and local government job sites typically require ADA-accessible shower facilities regardless of whether a disabled individual is currently on site
- Workforce camps and temporary housing: When shower trailers serve as the primary bathing facility for workers in camps or temporary housing, ADA-accessible units must be included
- Reasonable accommodation requests: When any worker requests accessible shower facilities as a reasonable accommodation under ADA Title I
Ratio Guideline
For public events, the general standard is at least 5% of total shower units (minimum 1) must be ADA-accessible. For construction sites and workforce camps, at least one accessible shower unit should be available whenever an accommodation need exists. Many contractors proactively include ADA units to avoid delays if a need arises mid-project.
What Makes a Shower Trailer ADA-Compliant?
ADA-compliant shower trailers must meet specific dimensional and feature requirements based on the ADA Standards for Accessible Design (2010 ADA Standards):
Roll-In Shower Stall
- Minimum size: 36 inches wide x 60 inches deep (roll-in type)
- Threshold: Maximum 1/2 inch (roll-in showers should have no threshold)
- Floor surface: Non-slip throughout the entire stall and approach
- Turning radius: 60-inch diameter clear floor space for wheelchair turning within or adjacent to the shower
Fold-Down Bench Seat
- Height: 17-19 inches above the finished floor
- Width: Full width of the stall wall (minimum 24 inches deep)
- Weight capacity: Must support at least 250 lbs
- Type: Fold-down design that can be raised when not in use to maximize floor space
Grab Bars
- Location: On walls adjacent to the seat and along the back wall
- Height: 33-36 inches above the finished floor
- Diameter: 1.25 to 1.5 inches, with 1.5 inches clearance from wall
- Length: Side wall bar minimum 42 inches; back wall bar minimum 48 inches
Shower Controls and Fixtures
- Control placement: Offset toward the entry, maximum 48 inches above floor
- Control type: Lever, push, or sensor — operable with one hand, no tight grasping or twisting
- Shower head: Hand-held spray on adjustable-height slide bar (minimum 60-inch hose)
- Soap dispenser: Mounted 15-48 inches above floor, operable with one hand
Access Ramp
- Slope: Maximum 1:12 ratio (1 inch of rise per 12 inches of ramp length)
- Width: Minimum 36 inches clear width
- Handrails: Required on both sides for ramps with a rise greater than 6 inches
- Landing: Level landing at top and bottom, at least 60 inches long
- Surface: Non-slip, firm, and stable — critical for wet conditions near shower trailers
Interior Dimensions
- Turning radius: 60-inch diameter clear floor space for wheelchair turning
- Door width: Minimum 32 inches clear opening (36 inches preferred)
- Door hardware: Lever handles or push/pull — no round knobs
- Floor: Level, non-slip surface with no thresholds greater than 1/2 inch

- Plan the path of travel: The route from the accessible parking area or work zone to the ADA shower trailer must be firm, stable, and slip-resistant (gravel, compacted soil, or temporary matting). Mud or loose gravel can make an otherwise compliant unit inaccessible.
- Level the trailer: An ADA shower trailer must be level for the ramp slope to meet the 1:12 maximum. Uneven ground can push the ramp slope beyond compliance even with properly designed equipment.
- Manage wet conditions: Shower trailers create wet exit areas. Place non-slip matting at the base of the ramp and ensure drainage directs water away from the accessible path of travel.
- Include ADA units proactively: Rather than retrofitting when a need arises mid-project, include at least one ADA shower unit from day one. This avoids delays and demonstrates good faith compliance.
- Signage: Mark the ADA-accessible shower unit with the International Symbol of Accessibility (ISA). Signage should be visible from the approach path.
