Why ARE toilet, shower, locker & dressing so tricky to get right under the 2010 ADA?
Ranges instead of absolute dimensions
Water closet centerline (16-18”)
Width of ambulatory accessible stall (35”- 37”)
Some absolute dimensions remain
e.g. transfer shower stall (36” x 36”)
(measured to center points;
manufacturing tolerances recognized)
Tolerances do not apply to ranges

Reach over obstructions
Turning Space
60” Diameter circle or “T” turn
(elements with knee/toe clearance can overlap)
T-Turn: overlap limited to one segment

Toilet
• Range for toilet centerline
• lavatory cannot overlap toilet clearance (except in dwelling units)
Toilet
Allows space for side transfers
Toilet
• fixtures can be recessed
• shorter (24” min.) rear grab bar allowed in this case
Toilet Rooms
Door maneuvering clearance; swing outside fixture clearances
Toilet Rooms
Doors can swing into fixture clearances if clear floor space (30” x 48” min.) provided outside swing

Toilet Rooms
Turning space can overlap fixture & door clearances; door can swing into turning space
Toilet Rooms
Same requirements apply for any design/ configuration

Toilet Stalls
• Stalls with more than 1plumbing fixture treated as toilet room
• Must have a second accessible lavlavatory outside stall

Grab Bars
ICC A117.1 requires 18”min. vertical grab bar (ADA and ABA guidelines do not)

Clearances at grab bars help ensure usability

Toilet Stalls
• stall door must be self-closing
• door pulls on both sides of stall door
• Door opening must be no more than 4” from the wall or partition farthest from the water closet.
• Maneuvering clearance for stall door allowed to be reduced to 42”.

Toe Clearance at Stall Ambulatory Stall
When 6 or more water closets are provided, one shall be an ambulatory stall.
Lavatories
Knee/Toe Clearances
Specified in Chapter 3 for all elements
(e.g., lavs, sinks, counters, tables, etc.)
Depth: 17” – 25”
Centering is advisable but required only at drinking fountains, kitchen work surfaces and W/D

Mirrors
• bottom edge of the reflecting surface 40 inches(1015 mm) maximum above the finish floor or ground.
• Mirrors not located above lavatories or countertops shall be installed with the bottom edge of the reflecting surface 35 inches (890 mm) maximum above the finish floor or ground.
• single full-length mirror

Other ways to control water:
• 2% max. slope allowed
• consider trench drain

Unisex toilet rooms
Family or Assisted-use Toilet and Bathing Facilities.
Required:
1 In assembly and mercantile occupancies with an aggregate of 6 male and female water closets
2 In buildings of mixed occupancy, only water closets required for assembly or mercantile shall be used to determine family toilet requirement.
3 In recreational facilities where separate-sex bathing facilities are provided (Exception: where each separate sex facility has only one shower or bathtub, a family bathing facility is not required.)

Non-Compliance:
-Transfer Showers
- Accessible BenchAgainst Wall
- Accessible Lockers
- Ambulatory Stalls
Product cut sheetsWhat makes this sink non-compliant?In-correct specified mounting heights!
Make sure you specify the proper mounting height for 27” clear knee space.
Product cut sheetsWhat makes this toilet and urinal difficult to use?
Push button valves
Product cut sheetsWhat is misleading about these shower stall specs?Incorrect CFS layout and Unlabeled grab bar height Going Beyond the Code
• Design for increased turning radius
• Design for higher knee clearance
• Design for a shorter horizontal reach
• Increase the % of wheelchair accessible toilet stalls in largest toilet rooms (when 15 or more WC in toilet room, provide at least 2 wheelchair stalls.)

Best Practices
• Design for construction tolerance
• Example: Toilet centerline to side wall must measure 18”(exact) for Fair Housing, 18” -16” for 2010 ADA and IBC/ICC A117.1.
• Consider Pre-con to clarify the importance of accuracy.
