ADA: Redesigning a Public Men's Bathroom based on ADA Regulations

Universal/accessible design of the home from an occupational therapy and a construction perspective. This blog is part of a quest for cool, convenient, functional design that makes life safer, easier, and as maintenance-free as possible. It's about the lifestyle.
I was recently asked to assist in redesigning a men's public bathroom to be ADA compliant.  Here is where we are beginning:

Existing Men’s Stall-not ADA

Features out of compliance with ADA regulations:

Features not in compliance with ADA regulations for size and arrangement of toilet stalls (4.17.3):

Large men’s bathroom stall:
·      The largest toilet stall is 40” wide x 59” deep, ADA codes states stalls must be 60”x 60” but allow the an exception based on the following: 
ADA 4.17.3:EXCEPTION: In instances of alteration work where provision of a standard stall is technically infeasible or where plumbing code requirements prevent combining existing stalls to provide space, either alternate stall may be provided in lieu of the standard stall. You may want to make sure your project qualifies.
o   The alternate stall can be 36” or 48” in width as long as the stall is 66” deep with a wall mount toilet or 69” deep with a floor mount toilet, per ADA: 4.17.3, Figure 30(b) **See ADA 4.17.3 below.
·      Centerline of toilet needs to be 18” on center from sidewall, currently 25” on center from side wall.
o   Per ADA code 4.17.3 : The centerline of the water closet shall be 18 inches (455 mm) from the side wall.
·      Need grab bar behind toilet because stall is wider than 36”.
·      Sink will need to face door in order to have 30”x 48” clear floor space. 
o   Sink should be wall mounted, 17”-19” deep measured wall to front edge of sink.
o   Sink basin needs to be no more than 7” deep.
o   Counter top height 34”.
o   Insulated pipes.
o   Paddle, infrared, or touch controls.
o   Mirror height 40”.

**ADA compliance code 4.17.3, Figure 30(b):  Two alternate stalls are illustrated; one alternate stall is required to be 36 inches (915 mm) in width. The other alternate stall is required to be a minimum of 48 inches (1220 mm) in width. 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 inch wide stall shall have parallel grab bars on the side walls. The 48 inch minimum stall shall have a grab bar behind the water closet and one on the side wall next to the water closet. In each alternate, the centerline of the water closet is 18 inches (455 mm) from a sidewall.

Features in compliance with ADA code-men’s bathroom stall:
·      Required 48” turn space in front of large stall.

Urinal Stall:  I’m not sure if the urinal stall needs to in compliance with ADA code if you already have an ADA code compliant toilet stall.  The only thing I could find stating if urinals are a required element of a men’s bathroom is ADA code 4.23.5 Urinals. If urinals are provided, then at least one shall comply with 4.18.  Code 4.18 only specifies requirements for positioning the urinal, floor space, controls, etc.

Features not in compliance with ADA code- urinal stall:
·      Need a minimum 36”x 48” space for a wheelchair to make a 90-degree turn into the urinal stall.  I can’t tell from the drawing, if you have a 36” space between the edge of the sink and the end of the stall you are set, if not the urinal is not considered accessible. 
o   ADA code:  4.3.3 figure 7a:  A U-turn around an obstruction less than 48 inches (1220 mm) wide may be made if the passage width is a minimum of 42 inches (1065 mm) and the base of the U-turn space is a minimum of 48 inches (1220 mm) wide.
Other recommendation:
·      Swing exterior door out of bathroom, or at the very least change hinge side to other side so that when the door is opened it doesn’t block the bathroom stalls.
·      Note:  Toilet stall doors may not swing into the stalls.

 It is my understanding that you don't need an accessible urinal if the bathroom stall is accessible but as with everything else the ADA regulations are open to interpretation and all plans should be approved by the local building official to ensure compliance.

Anyone else have a project or a suggestion?  It's always good fun to work together, please let us know your thoughts. :-)
