Purpose and Learning Objectives
Purpose: Restroom facilities should provide easy access and use for all users, regardless
of ability. It is becoming increasingly important to know the tools needed to properly plan an
accessible restroom that will meet the requirements of the ADA and other standards. This
course will explore how accessibility standards accommodate a wide range of users,
including how to design lavatories, toilet compartments, bathing facilities, and their
accessories to meet accessibility requirements.
Learning Objectives:
At the end of this program, participants will be able to:
• identify how accessibility standards accommodate a diverse set of users and the
general prescriptive requirements for accessible restroom design mandated by the ADA
• describe requirements for accessible lavatories and restroom accessories
• describe requirements for accessible toilet compartments of varying sizes and the
accessories needed to complete their specification, and
• discuss requirements for accessible bathing facilities.

The 2010 Americans with Disabilities Act (ADA)
The 2010 ADA standards are the latest in a series of
guidelines that have been issued by the United States
Access Board and enforced by the Department of
Justice. The law applies to most buildings and facility
types nationwide, but it is not a building code.
The Americans with Disabilities Act is a federal civil
rights law that prohibits discrimination against people
with disabilities by ensuring equal access to goods
and services. It recognizes inaccessible facilities as a
form of discrimination, since these inaccessible
facilities can prohibit participation by people with
disabilities.
Slide 10 of 77< >
2010 ADA standards on many projects.
Changes in the 2017 Edition of the ICC A117.1
Standard that impact accessible restroom design will
be reviewed throughout the presentation.
Additionally, as you go through the presentation,
helpful learning points will be provided and noted as a
“Take-Away Alert.” Here is “Take-Away #1”; there
will be twelve throughout this presentation.

range of users such as people with
temporary health problems, older people,
Slide 12 of 77< >
It is also important to consider a person’s sensory
abilities. This includes visual impairments such as low
vision or blindness, and being hard of hearing or deaf.
Designing restrooms to avoid protruding objects,
increasing lighting levels and providing strobe lights on
the fire alarm system are examples of supporting safety
for users with sensory disabilities.
One trend that recognizes the need for assistance for
many restroom users is the increased presence of family
restrooms. These restrooms will accommodate diaper
changing, adults with children, older individuals who
need assistance, particularly from opposite gender
Slide 13 of 77< >
Clear Floor Space Requirements
The standards designate clear floor space to accommodate a single wheelchair of at least
30″ x 48”. The arrows highlight areas where clear floor space is necessary.
Examples of where clear floor space is necessary
Slide 14 of 77< >
The 2010 ADA Standards designate clear floor space to accommodate a single wheelchair
of at least 30” wide by 48” long. The 2017 ICC A117.1 Standard increases the clear floor
space for a wheelchair in new buildings to 30″ wide by 52″ long, minimum; for existing
buildings the 30″ by 48″ minimum clear floor space does not change.
Clear floor space at lavatories, urinals, and baby changing stations must be positioned for
forward approach (red arrows in diagram). A portion of the clear floor space may be
located under countertops, lavatories, or accessories as long as the required knee and toe
clearance is provided.
Forward approach is required at lavatories and sinks. Exceptions where parallel approach
is permitted include a kitchen sink in a residential facility, a lavatory in a toilet room or
facility for a single occupant accessed through a private office; not for public use, and a
lavatory used by children 5 years and younger .
Clear floor space at other restroom elements, such as paper towel dispenser/waste
receptacle units and hand dryers, can be positioned for both front and parallel or side
approach (green arrows in diagram).
Slide 15 of 77< >
Take-Away #2: If properly centered in front of controls and operating mechanisms, the
clear floor space will allow both left- and right-hand access.
Slide 16 of 77< >
Mounting Heights
Mounting heights for restroom accessories may vary within a facility depending on the
location of individual accessories and the direction of reach required for their use.
To allow use by people with limited reach range, it is required that accessories, other than
toilet tissue dispensers, be mounted with their “operable parts” (dispensing mechanisms,
start buttons, coin slots, or dispenser openings) located no more than 48″ above the finish
floor, as illustrated in the diagram below. Note that in the state of California, the maximum
mounting height for “operable parts” on some restroom accessories is 40″, not the 48″
maximum as stated in the 2010 ADA and 2009, 2017 ICC A117.1.
Slide 17 of 77< >
Mounting Heights
The operable portions of toilet tissue dispensers should be mounted no lower than 15″
above the floor. In the state of California, operable portions of toilet tissue dispensers
should be mounted no lower than 19″ above the finish floor. However, the ICC A117.1
2009, 2017 Standards limit the operable portions of toilet tissue dispensers in toilet
compartments to no lower than 18″.
Where accessories are mounted over obstructions such as counters, their operable parts
must be located a maximum of 48″ above the finish floor when the obstruction is 20″ deep
or less, and a maximum of 44″ above the finish floor when the obstruction is 20″ deep or
more. When determining the mounting location of restroom accessories, make sure to
account for side and forward approaches.
Take-Away # 3: It is best practice to locate one set of each type of dispenser outside of
the toilet compartment on an accessible route for increased accessibility.
Slide 18 of 77< >
Turning Spaces
Wheelchair turning space in restrooms may be defined as circular space, shown on left, or
T-shaped turning space, shown on right.
A circular space allows a person using a wheelchair to make a 180-degree or 360- degree
turn. The 2010 ADA and ICC A117.1-2017 standards for existing buildings require a 60″
minimum diameter circular space. For new buildings, the ICC A117.1-2017 requires a
circular space of 67″ minimum diameter.
60" Diameter Turning Space T-Shaped Turning Space
Slide 19 of 77< >
Turning Spaces
A T-shaped turning space allows for a three-point turn and can be used to conserve space
in some installations. The 2010 ADA and ICC A117.1-2017 standards for existing buildings
require a 60” minimum square with arms and base 36” wide minimum. For new buildings,
the ICC A117.1-2017 standard requires a 68” wide by 60” deep minimum rectangle with
two arms and one base all 36” minimum width, or two 64” wide by 60” deep minimum
rectangular options. One option, with two arms 38” minimum width and a base 42”
minimum width, and a second option with two arms and one base, all 40” minimum width.
A portion of the 60″ diameter or T-shaped turning spaces may be located under fixtures,
lavatories, or accessories as long as the required knee and toe clearance is provided.
Slide 20 of 77< >
Children’s Reach Ranges
When designing restrooms primarily for children’s use, select the dimensions that are most
appropriate for the specific children’s age group for which you are designing. Mounting
heights for children vary depending on age. Ages can be grouped as follows: 3 and 4, 5
through 8, and 9 through 12 years. These tables are a guide and offer recommended
heights for each age group. These dimensions are not required standards.

changing the dispenser spindle, or by
replacing an item with one that is more
adjustable or adaptable, such as replacing
a folded paper towel dispenser with an
automatic roll paper towel dispenser.

Restroom accessories with leading edges between
27″ and 80″ above the finish floor shall protrude 4″
maximum into a circulation path. Should the
leading edge be at or below 27″, the restroom
accessory may project any amount as long as the
required minimum width of an adjacent clear
access aisle is maintained. This standard is
specifically designed to ensure detection by people
who use canes along the base of walls.
All floor-standing and surface-mounted units
protruding more than 4″ should be located in
corners, alcoves, or between other structural
elements.

Soap Dispensers
Soap dispensers installed over lavatories must be mounted so push buttons or operable
parts meet specified reach ranges. When the soap dispenser is mounted more than 20″
from the edge of the counter, the soap dispenser mounting height is 44″ maximum above
the finish floor.
Lavatory-mounted soap dispensers and lever-handled faucets should be spaced far

public and private schools that meet the 40% poverty threshold to operate a school wide
program, stock 50% of the schools’ restrooms for grades 6 through 12 with sanitary
napkins and tampons. Schools shall not charge for these feminine hygiene products.
Changes like these tend to eventually find their way into the state building code, which
Slide 36 of 77< >
Baby Changing Stations
Baby changing stations are increasingly found in men’s and women’s restrooms and in
single-user (family) restrooms as well.
While not required by the accessibility standards, baby changing stations are widely
regarded as an important or even essential feature in many facilities, particularly those
facilities that serve families.
In October 2016, the BABIES (Bathroom Accessible in Every Situation) Act was signed into
law requiring all publicly-accessible federal buildings to have baby changing stations in
both men’s and women’s restrooms. Changes like this tend to eventually find their way into
state laws and into building codes, which cover privately-owned commercial facilities.
Baby changing stations need to be located with care to provide for the needs of users while
not preventing other restroom users (including people who use wheelchairs) from gaining
access to and using the fixtures and dispensers in the restrooms.
Slide 37 of 77< >
stations must comply with the following:
mounting height to operate, with the
handle to open and close located 48”
maximum above the floor; clear floor
space (30″ x 48″ minimum); design of
handles and controls (operable with one
hand, without tight grasping, pinching, or
twisting of the wrist), required force to
open and close (maximum of 5 pounds of
force (lbf), mounting height (working
surface in the down position, 34″
maximum), knee space (27″ vertically to
underside), and toe space (17″ minimum
to 25″ maximum).
stations are not required to comply with
the 40″ maximum mounting height .
Slide 38 of 77< >
Baby Changing Stations
If your state considers baby changing stations in the down position as the dominant
position, then you will need to follow the rule for protruding objects.

of the unit that extend below 27” above the floor for the full depth of the open changing
bed.
Slide 39 of 77< >
location for a child generally weighing up to 50 lb.
Unlike the baby changing stations, child protection
seats should be installed inside a toilet compartment
to provide visual and physical access. Like the baby
changing stations, they should be assessed for
operability and reach in the up and down positions.
Make sure there is adequate space to maneuver
around the seated child when the seat is in the down
position. For easier reaching, the bottom of the
lowered seat should be no less than 15″ above the
finish floor—the minimum reach range distance
allowed by 2010 ADA and 2009, 2017 ICCA117.1
Standards .
Slide 41 of 77< >
Accessible Toilet Compartments
Accessible toilet compartments are required in all public restrooms. There are two basic
toilet compartment designs that are shown in the standards: the wheelchair accessible
toilet compartment and the ambulatory accessible toilet compartment.
The wheelchair accessible compartments should accommodate people who use
wheelchairs and transfer onto and off of a toilet using a variety of approaches. The
ambulatory accessible toilet compartment accommodates people who use canes, crutches,
or walkers to assist their mobility. Three common transfer positions are diagonal, side, and
perpendicular.

must be 56″ minimum for wall-hung toilets
and 59″ minimum depth for floor-mounted
toilets. The minimum width is 60″.
Slide 43 of 77< >
The minimum space required allows a person using a wheelchair to maneuver onto and
off of the toilet. The toilet, positioned diagonally across from the door, must be offset on
the back wall with the toilet centerline 16″ minimum to 18″ maximum from the side wall or
partition.
Take-Away #6: Some jurisdictions have different requirements for wheelchair accessible
toilet compartment size and configuration. It is recommended to check with local codes.
As an example, the 2016 California Building Code requires “A minimum 60” wide and 48”
deep maneuvering space in front of the toilet.” This requirement eliminates use of the
nominal 60” square Wheelchair Accessible Toilet Compartment in the state of California.
The Large Wheelchair Accessible Toilet Compartment 8 feet long, 5 feet wide, frequently
used at the end of the restroom, complies with the California requirements.

horizontal side grab bar.
Slide 45 of 77< >
Large Wheelchair & Ambulatory Accessible
The large wheelchair accessible toilet compartment shown is a common end-of-the-
restroom alcove layout. Note that in-swinging doors must not overlap the required 56″ x 60″
clear floor space at the toilet.
The ambulatory accessible toilet compartment shown on the right has a depth of 60″
minimum with 2009 ICC/ANSI standards retaining the 36″ absolute width dimension. (The
2010 ADA standards allow a range of 35″ to 37″ maximum width.)

the 36″ absolute width dimension. Both the
2010 ADA Standards and the ICC A117.1-
2017 Standards allow a range of 35”
minimum to 37” maximum width.
Although lack of harmony between some
aspects of ADA and A117.1 accessibility
standards can be a source of frustration for
some design professionals, the required
dimensions for Ambulatory Accessible Toilet
Compartments are consistent across both
standards. Ambulatory accessible toilet compartment
Slide 47 of 77< >
Ambulatory Accessible
Self-closing doors must not swing into the minimum required compartment area. Door pull
hardware must be installed on both sides of the door near the latch.
Horizontal grab bars must be provided on both sides of the toilet compartment. Additionally,
the 2009, 2017 ICC A117.1 Standards require a vertical grab bar, 18″ long minimum, be
installed above the horizontal side grab bar on both sides of the toilet compartment.
Install coat hooks and shelves to complete the design.
Take-Away # 7: The ambulatory accessible toilet compartment is used, in addition to a
wheelchair accessible toilet compartment, where six or more fixtures, including toilets and
urinals, are provided.
Slide 48 of 77< >
Toe Clearance
Per the 2010 ADA standards, toe clearance of 9″ minimum above the finish floor for adults,
12″ minimum for children, is required under the front and one side of all accessible
compartments.
Take-Away #8: Toe clearance at the front is not required if the depth of the compartment is
greater than 62″ deep with a wall-hung toilet, or 65″ deep with a floor-mounted toilet. Toe
clearance at the side is not required in a compartment greater than 66″ wide. The toe
clearance must extend 6″ deep minimum beyond one compartment side and the front face
of the toilet compartment.
Slide 49 of 77< >
Toe Clearance
In the ICC A117.1-2017 Standard, the toe clearance requirement remains at 12” high
minimum for adults and children but now must extend 8” minimum (it was 6”) beyond
compartment front and one side, exclusive of partition stiles.
Toe clearance at front and side is not required on compartments greater than 67” in depth
and 68” in width (it was 65” in depth and 66” in width).
Slide 50 of 77< >
must include door pull hardware and self-
closers. There must be a clear width

maneuvering clearances and impede
Slide 51 of 77< >
Doors
Note that zero latch-side clearance is allowed for a front approach to an in-swinging
door to a wheelchair accessible toilet compartment because the door requires a
simple push-in operation from the outside and the door has neither conventional door
latch nor conventional closer.
A front approach to a door that you have to pull would require 18” of latch side
clearance. Other latch or hinge side approaches may require different clearances.

Also note that maximum and minimum
horizontal mounting heights of grab
bars are set to the top of the gripping
surface instead of the grab bar
centerline.

Grab Bars Required in All Compartments
The sidewall grab bar next to an accessible toilet in a
compartment must be 42″ long minimum, located 12″
maximum from the rear wall, and extending 54″ minimum
from the rear wall.
Take-Away #9: It is recommended to use a 48″ long side
wall grab bar. The 6” longer bar eliminates many
installation compliance problems.
The 36″ grab bar required to be mounted on the rear wall
behind an accessible toilet must be located with 24″

Toilet Tissue Dispensers
Roll toilet tissue dispensers that allow continuous paper flow are required in all accessible
toilet compartments. Dispensers that control continuous paper delivery should not be used.
The 2010 ADA standards require that roll toilet tissue dispensers must be installed with the
dispenser centerline 7″ minimum to 9″ maximum in front of the leading edge of the toilet.
The 2009, 2017 ICC A117.1 Standards establish a different measurement procedure,
locating toilet tissue dispensers between 24″ minimum and 42″ maximum from the rear wall
Slide 58 of 77< >
As mentioned previously in the mounting heights section, and shown in this photograph,
the 2009, 2017 ICC A117.1 Standards locate the outlet (bottom of the lower toilet tissue
dispenser) no lower than 18″ above the finish floor. The 2010 ADA standards allow the
outlet of the dispenser to be mounted as low as 15″ above the finish floor. In California, the
outlet of the dispenser can be no lower than 19″ above the finish floor.
Slide 59 of 77< >
In the ICC A117.1-2017 Standard, an exception has been added to toilet tissue dispensers.
Dispensers that accommodate two rolls not more than 5” in diameter are permitted to be
located 7” minimum to 9” maximum from dispenser centerline to leading edge of the toilet.
Dispenser outlet shall be 15” minimum and 48” maximum above the floor.
Again, although lack of harmony between some aspects of ADA and ICC/ANSI accessibility
standards can be a source of frustration for some design professionals, the required
dimensions for toilet tissue dispensers are consistent across both standards.

compartments. They should be within
reach from a sitting position, and it is
recommended that they be mounted
below grab bars.
The opening for the toilet seat cover
dispenser needs to be mounted between
15″ and 48″ above the finish floor, in an
accessible location in relation to the
leading edge of the toilet per the 2010
ADA standards, or the rear wall per the
2009, 2017 ICC A117.1 Standards , in
the accessible compartment.

Dispensers & Disposals
Recessed combination units installed in side walls or partitions with grab bars can organize
and unify installations by incorporating several accessories at one convenient location ,
such as toilet tissue dispensers, toilet-seat-cover dispensers, and sanitary napkin disposals
improving accessibility.
As pointed out earlier, the ICC A117.1 Standard includes an exception that allows recessed
units behind grab bars with less than 1½″ absolute wall clearance as shown in the
photograph on the previous page.
Note that if compliance with the 2010 ADA Standard is a concern , specify and install
separate recessed or surface-mounted accessories a minimum of 1½″ below the horizontal
grab bar.

least one wall-hung or stall- type urinal
installed with the rim 17″ maximum above
the finish floor. Urinals must be 13 ½″
minimum deep measured from the outer
face of the urinal to the back of the fixture.
The operable portion of the flush valve must
be mounted no higher than 48″ maximum
above the floor, or no higher than 44″ if the
urinal extends far enough to create at least
20″ of reach (44″ maximum height in
California).
A clear floor space of 30″ wide by 48″ deep
minimum must be provided to allow forward
approach.

folding L-shaped shower seat mounted
on a side wall, opposite the shower
head and controls. The 36″ by 36″
inside dimension addresses the reach
and safety needs of adult users.
Slide 66 of 77< >
Transfer Shower Compartments
Curbs may be installed, but they must be no higher than ½″.
Minimum clear floor space of 36″ by 48″ must be positioned outside the shower
compartment to allow proper wheelchair positioning for transfer to/from a shower seat. In
the ICC A117.1-2017 Standards, for new buildings a 36” wide x 52” length minimum clear
floor space is required adjacent to open face of the transfer shower compartment. For
existing buildings the clear floor space is 36″ wide x 48” long minimum.
Handheld showers on a hose that can be used as both a fixed shower head and a
handheld shower head are required in accessible showers. The hose must be a minimum
59″ long. Use of an adjustable vertical slide bar for the handheld unit is optional.
Note that while the Transfer Shower Compartment is in both the 2010 ADA and 2009, 2017
ICC A-117.1 Standards, the Transfer Shower Compartment is not in the 2016 California
Building Code.

who use a castered shower chair for
bathing. The accessibility standards also
refer to the standard roll-in type shower
compartment as a curbless shower.
Roll-in shower compartments are
intended primarily for remodeling
of an existing tub with a roll-in shower
compartment.
Additionally, the ADA and ICC A117.1 Standards require a clearance 30″ wide minimum by
60″ long minimum shall be provided adjacent to the open face of the standard roll-in
shower compartment. Note that the California Building Code requires a clearance 36″
wide minimum by 60″ long minimum.
Slide 68 of 77< >
Roll-In Shower Compartments
Take-Away #11: In most cases the 30″ x 60″ minimum size is inadequate due to the
difficulty in containing water within the 30″ depth. Consider larger sizes for easier
maneuvering and less water spillage, such as 36″ x 60″, 48″ x 60″ and 60″ x 60″.
Curbs should be avoided or minimized. If it is necessary to include them, then curbs
should be ½″ high maximum.
Minimum clear floor space of 30″ wide x 60″ must be positioned outside the shower
compartment to allow wheelchair maneuvering space. This space may incorporate knee
clearance under adjacent lavatories or countertops.
Slide 69 of 77< >
Grab bars must be installed in all accessible bathing facilities.
Horizontal grab bars in showers must be mounted 33″ to 36″ to the top of the gripping
surface above the finish floor. Two horizontal grab bars or a single two-wall horizontal grab
bar must be installed on the walls next to and opposite the folding shower seat in transfer
shower compartments as shown on the following slide.
Standard roll-in shower compartments must have grab bars installed 6″ maximum from
the corners as shown in the right-hand illustration on the following slide.
2009, 2017 ICC A117.1 Standards require that transfer and roll-in shower compartments
must also have a vertical grab bar 18″ long minimum mounted on the control wall and 4″
maximum from the front edge, as shown in both illustrations on the following slide.
Slide 70 of 77< >
Slide 71 of 77< >
Combination tub/shower units must have a
horizontal grab bar mounted at the foot of the tub
that extends at least 24″ from the front edge of the
tub, and two parallel, horizontal grab bars mounted
on the back wall. The upper grab bar is mounted at
standard height and the lower grab bar is mounted
8″ to 10″ above the tub rim.
In tubs with a removable in-tub seat, the back wall
grab bar lengths are specified at 24″. Bathtubs with
removable in-tub seats must have a fourth horizontal
grab bar mounted at the head of the tub that extends
at least 12″ from the front edge of the tub.
2009, 2017 ICC A-117.1 Standards require that
bathtubs have a vertical grab bar 18″ long minimum
mounted on the control wall, 4″ maximum from the
front edge.

roll-in and transfer compartments, seats must
have a 3″ maximum space between the seat edge
and the compartment entry-opening, a larger
permissible 2½″ maximum gap between the seat
and seat wall, and a 1½″ maximum space from
the side edge of the seat to the adjacent wall. Rectangular
Take-Away #12: Note the maximum 3″ space allowed between seat edge and
compartment entry. Previous standards required the seat to be full depth of a 36″ x 36″
compartment, which pushed the shower curtain beyond the entry of the compartment and
allowed water to flow onto the floor outside the compartment. This maximum 3″ space
allows the shower curtain to hang vertically, keeping water within the compartment.

now use a rectangular seat design shown on the
prior slide as well as the previously required L-
shaped design shown on the right.
Upholstered, cushioned seats shown in the
photograph are preferred by many people with
disabilities, while water-resistant solid phenolic
(class of chemical compounds) seats are vandal-
resistant and more sanitary.
Slide 74 of 77< >
Soap dishes should be placed on the same wall as
the shower head and controls where they are least
likely to collect standing water.
It is recommended that soap dishes be recessed
and mounted 38″ to 48″ (40” maximum in
California) above the finish floor when installed in
shower compartments, or they should be mounted
between the grab bar and the rim of the bathtub.
