Welcome to the ICC Codes & Standards Discussion Forum

The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.

No other fixtures or obstructions shall be within the required water closet clearance.

This is to allow for a side transfer. A wheel chair could not get back far enough if another fixture was in this space.

cabin has it, prior to that last limiting sentence in the section, elements that ARE allowed to overlap into the required 60" are described, and the lav is not included.

I agree with fat and cabin... the side transfer from a wheel chair is the deciding factor..

Agree with fatboy and cabin! The most commom mistake made in Bathroom layout. Some put the sink in an alcove to reduce the size, but the 60" still holds.

So with a typical 20" wide sink we are looking at a minimum of a 80" width for that type of setup.

What is the smallest possible accessible bathroom with a water closet and lav?

The regular ADA manual allows what I am talking about but the ANSI 117 does not.

Actually it''s 85" if the lavatory is on the same wall as the WC. The IPC requires 15" from the CL of the lavatory to the wall.

Lavatories used to be allowed to be 18" from the CL of the water closet, but not any more. I think it was changed in 2003. The current ADAAG also prohibits lavatories from being in the clear space, except in a residence.

Let''s rethink this..

18" from partition/wall to CL of toilet..

Minimum stall is 60".. so we have 42" left..

Minimum clear space for doors is 32".. so leave 32" for transfer space..

10" left..

15" from CL of lav to wall..

yup.. looks like 85" if all fixtures are on one wall..

Don''t make the room bigger... reorganize it.

[QUOTE]What is the smallest possible accessible bathroom with a water closet and lav?[/QUOTE]One way to use space more efficiently is to use a swing-up grab bar for the WC. An example of this is shown in ANSI-117 fig 604.5.3.

With this method you should be able to get both the WC (27" deep) and lav (20" deep) on the same plumbing wall with an ADA and ANSI-117 code compliant 60" turnaround within a room size of about 5''9" x 6''8".

604.5 Grab Bars.
Grab bars for water closets shall comply with Section 609 and shall be provided in accordance with Sections 604.5.1 and 604.5.2. Grab bars shall be provided on the rear wall and on the side wall closest to the water closet.

Swing up bars are 604.5.3

Swing up bars are permitted in Type B units only 604.5 exceptions 4 & 5.

Agreed. The OP used the word "bathrooms" that lead me to dwelling and sleeping units in chapter 10. I do agree that only type "B" units meet the swing-up bar exceptions as you note. But still a good way to reduce space if conditions permit.

What don''t they understand about

clearance can overlap clearances but a fixture CANNOT OVERLAP another fixtures clearance.

the college I went to (in the early 70''s) required all architecture students to stay in a wheel chair for a week.

Now that I read it again with the explanation of others, I see how I was trying to split hairs to make something sound like what I wanted it to. I allowed someone elses slant to skew the way I make an interpretation. I should know better. I am trying very hard to be open minded and look from the other side to see if I am missing or misunderstaning something that I am starting to question myself. I better go back to being stubborn and closed minded. Let them prove me wrong rather than trying to understand what they are saying.

Actually, the ADA manual has it wrong.

The illustration in the ADAAG that shows the lav within the 60 space was a mistake. The intent was that it was to be used only for residential occupancies where the lavatory can encroach on the water closet clear floor space. It''s being fixed in the next edition (if we ever get it adopted by the DoJ . . . )

The 2006 IBC Commentary Figure 1109.2 (1) has some pretty good diagrams to illustrate the side transfer requirements.
The 60 inch clearance at the W.C. allows a side transfer from a wheelchair, but this clearance also benefits persons with a disability that may use crutches, braces, walkers, need an assistant, or are simply oversized.

Part of the confusion with the lavatories is that ADA (& I believe the ''98 ANSI-don''t have one handy to check) has shown them in the clear space in previous versions. I don''t know if it was a mistake as genebko says or just a change in thinking on accessibility. I''ve assumed it was a change a thinking.

Up until the 2003 ANSI was adopted locally, I designed many toilet rooms with the lav in the clear space of the toilet. It was the accepted design at the time and was never questioned. The ANSI A117.1-2003 version is very clear this is no longer accepted. I guess whether it was a mistake or a change, it doesn''t really matter as it is now very clearly stated.
