The Americans with Disabilities Act (ADA) is a mandate that prohibits discriminatory action against those who suffer from various disabilities. Compliance with this mandate requires all structurally practicable facilities constructed after January 26th, 1992 to contain at least one fully accessible stall for disabled users as per Title II and III regulations. Additionally, any constructions completed prior to the instillation of this mandate will need to be updated to standard when making a modification.
The ADA laws are enforced at a federal level, and failure to meet the documented standards can result in violations and extremely large fines. As a result, it is absolutely necessary to be mindful of the architectural requirements during installation to ensure that an accessibility-complaint toilet partition (and respective accessories) can be appropriately installed. To assist in this process, we have added a copy of the federal guideline for reference. Additionally, one of our manufacturers, Bobrick, has taken the time to create a very detailed ADA planning guide with dimensions, images, and other various visuals to make the process a bit more seamless.
Baby Changing Stations
Baby changing stations require careful placement for ADA compliance, as they have to be placed in a way where they do not obscure the progress of those who are in a wheelchair. The installation of a baby changing station requires a 30" x 48" clear floor space from the wall that it is attached. It is also advised that the baby changing stations are placed next to a lavatory and/or waste receptacle.
Compliance with ADA is highly contingent on the location of the door, as exterior doors and interior doors have differing requirements.
Entries with a single door: in this case, the door has an inswing towards the restroom; inside, a clearance of 48 inches should be provided to allow for optimal maneuverability. Doors leading into bathrooms must have a minimum clearance of 32 inches width, swinging inward.
Entries with opposing doors: in this case, two doors sit opposite from one another; a width of 48 inches should exist inside of the restroom to ensure adequate maneuverability. In an opposing door structure, the door designated as the entrance should swing inward towards to the bathroom, while the door designated as the exit should swing outward away from the bathroom. This provides optimal accessibility for both those who are in a wheelchair and those who require assistance for normal ambulatory function.
Any doors used for interior must be possible to pull and/or push open with no more than 5 pounds of force. Parts to be operated (locks, latches, and handles) have to be easily usable with one hand and should be mounted between 34 and 48 inches above the floor.
It is a requirement to have grab bars in all accessible bathroom stalls.
Grab bars should be mounted no more than 36 inches above the floor for an adult, or 27 inches above the floor for a child. In an accessible toilet, a grab bar that exists on the side wall of the partition must be at least 42 inches long. Grab bar mounting should reside no less than 54" away from the back wall.
In addition, a grab bar will need to be mounted on the back wall as well. The length of the grab bar behind the toilet should be 36 inches, if space permits. The centerline of the toilet is used to determine the horizontal placement: 12 inches will reside to the right of the toilet, and 24 inches will reside to the left. If space does not permit to have a 36 inch grab bar, a 24 inch grab bar will be used, centered along the centerline of the toilet.
Warm air hand dryers need to have points of operation no higher than 48 inches off of the finished floor. It should also be no lower than 44 inches off of the ground. Instances where two or more dryers exist should be treated slightly differently: it is strongly advised that multiple dryers are added such that left and right hand usage are both appropriately accommodated for. In a situation where two or more dryers are used, set one of the dryers 40" above the ground and set another one at 48" inches about the ground, keeping mindful of left and right handed orientation.
Sanitary Napkin / Tampon Vendors
Mirrors should be mounted either 35 inches off the ground (if not mounted over counter or lavatory) or 40 inches to from the ground to the bottom of the mirror's reflective surface.
Proper installation requires a 30" x 48" clear floor space. Parts of the vendor required for operation should be mounted anywhere between 15 inches above the ground to 48 inches above the ground. Sanitary napkin/tampon vendors containing any sort of push button must be able to operate with less than 5 pounds of force.
Mounting height of soap dispensers are no higher than 44 inches above the floor. Situations where the soap dispenser is mounted directly on the lavatory require adequate spacing between the dispenser and the faucet so that usability is maximized.
Toilet seats should have a relatively fine height, between 17 and 19 inches; however, if the facilities are heavily used by young children, it might be necessary to compensate accordingly.
The size and arrangement of the standard toilet stall shall comply with figure here-under, Standard Stall. Standard toilet stalls with a minimum depth of 56 in (1420 mm) shall have wall-mounted water closets. If the depth of a standard toilet stall is increased at least 3 in (75 mm), then a floor-mounted water closet may be used. Arrangements shown for standard toilet stalls may be reversed to allow either a left- or right-hand approach. Additional stalls shall be provided in conformance with 4.22.4.
The minimum width of the stall is 60 inches (1525 mm). The centerline of the water closet is 18 inches (455 mm) from the side wall. The location of the door is in front of the clear space and diagonal to the water closet, with a maximum stile width of 4 inches (100 mm). An alternate door location is permitted to be on the adjacent side (side wall) of the stall also diagonal to the water closet with a maximum stile width of 4 inches (100 mm). If a wall mounted water closet is used, the depth of the stall is required to be a minimum of 56 inches (1420 mm). If a floor mounted water closet is used, the depth of the stall is required to be a minimum of 59 inches (1500 mm). A grab bar at least 36 inches (965 mm) long shall be located behind the water closet, with one end no farther than 6 inches (150 mm) from the inside corner of the stall. Another grab bar shall be mounted adjacent to the water closet on the side wall and extend from no more than 12 inches (305 mm) from the back wall to at least 52 inches (1320 mm) from the back wall.
Rear Wall of Standard Stall
Grab bars located behind the water closet shall be at least 36 inches (915 mm) in length. One end of the grab bar is shown near the corner of the stall closest to the water closet. Figure 30(a) shows this end 6 inches (150 mm) maximum from the corner. All grab bars shall be located 33-36 inches (840-915 mm) above the finish floor.
Standard Stall (end of row)
If a standard stall is provided at the end of a row of stalls, and if the length of the stall is extended at least a minimum of 36 inches (915 mm) beyond the required minimum length, the door (if located on the side of the stall diagonal to the water closet) may swing into the stall. Two grab bars are located in the rear and the side of the water closet. The centerline of the water closet is 18 inches (455 mm) from the side wall with a long grab bar.
In standard stalls, the front partition and at least one side partition shall provide a toe clearance of at least 9 in (230 mm) above the floor. If the depth of the stall is greater than 60 in (1525 mm), then the toe clearance is not required.
Side grab bars shall be located 33-36 inches (840-915 mm) above the finish floor and shall be no more than 12 inches (305 mm) from the rear wall. Grab bars shall be at least 40 inches (1015 mm) long or at least 42 inches (1065 mm) long for alternate stalls. Water closet seat heights shall be between 17 inches (430 mm) and 19 inches (485 mm). Toilet paper dispensers shall be below the grab bar and at least 19 inches (485 mm) above the floor and no farther than 36 inches (915 mm) from the rear wall, measured to the far side of the dispensers.
Two alternate stalls are permitted for alterations only; one alternate stall is required to be 36 inches (915 mm) wide. The other alternate stall is required to be a minimum of 48 inches (1220 mm) wide. In either alternate stall, if a wall mounted water closet is used, the depth of the stall is required to be a minimum of 66 inches (1675 mm). If a floor mounted water closet is used, the depth of the stall is required to be a minimum of 69 inches (1745 mm). The 36 inches (915 mm) wide stall shall have parallel grab bars on the side walls. The 48 inches (1220 mm) minimum stall shall have a grab bar behind the water closet and one on the side wall next to the water closet. Grab bars are mounted 33-36 inches (840-915 mm) above the finish floor. In both alternate stalls, the centerline of the water closet is 18 inches (455 mm) from a side wall. In both alternate stalls, the grab bars along the sides of the water closets shall extend at least 54 inches (1370 mm) from the back wall and shall have one end no farther than 12 inches (305 mm) from the back wall.
