simple commercial ada restroom design

ponytl | Posted in General Discussion on June 3, 2008 02:25am

maybe i’m missing something but i did a web search and you’d think there would be a simple standard design…   i know the basics…  32″ outswing door  18″ throne 36″ wide stall outswing door (if you have a stall)  34″ max sink ht with 29″ min under it, 30-48″ space in front of sink but 19″ can be counted under the sink… 5ft clear turnaround for wheelchairs… the grab rails mirror hts ect…  but seems there would be a simple basic design somewhere….

    pt, go in the restroom of a newer gas station.

    Doesn't get any more simple than that design.

    You probably don't need to install the rubber machine.

      you are 100% right... go to a new exxon and measure....  i did find online a topic where some design firm patented a ada restroom design that met code and saved space...  no drawings but as i understood it... the watercloset was 2ft out from the back wall and the lav was behind it... where the lav countertop would come over the toilet tank... this was in a hospital where any other design would have cost them 1 bed on the floor...  and one bed equates to 250K in profit per year for that hospital... i can see where they wouldn't want to lose one... i'd be building bunk beds in hospitals

    Wow, I thought it'd be a simple thing--I'd just look up the requirements in my Code book. If they say anything in there about it, I sure couldn't find it! I've seen books in the local library about it. I suppose you could get a copy of the Act somewhere and the Rules section should have minimum standards. Sorry I couldn't help!

    Hey ponytl, double check the32' outswing door, i don't ever recall installing anything less than a 36" inswinging door.  I dont think they allow doors swinging into hallways.

    1. jrnbj | Jun 03, 2008 04:11am | #4

      yep, 3'0" door. Inswing or outswing sort of depends on what works best....from an ADA perspective it doesn't matter....BUT...there are dimensions/standards for approach side clearance to the door handle...

      1. ponytl | Jun 03, 2008 05:50am | #6

        12" clearance on the latch side...   they "prefer" out swing because.. if someone falls out of their wheel chair they & the chair could block the inswing of the door so no one could get in to help...  just what i read... 42" min hallway leading to the door... we have always used 36" doors  but the ada calls for min of 32"  the "stall has to be 36 wide"....

        thanks

          So not only do you have to re configure the whole entire bathroom for a remodel, you also have to re build the hallway leading up to it? And in effect, every room off the hallway? We ran into a problem with his last year. We removed a kitchen, bathroom, and break room in our kitchen showroom. Our plan was to use the space as a functional display of a modern style bathroom and use the rest as storage for new cabinets waiting to be installed on jobs. The fire inspector came in for his annual and noticed that the room was under construction and literally dialed the building inspector while he was standing there. The building inspector, having nothing better to do, showed up in about 5 minutes and told us to stop working on it. There had never been a public bathroom in the showroom for the last 23 years. Now, since we were installing a new display it had to be public and also be handicapped accessible. We re built the bathroom to make it large enough, but haven't done anything since then. It's not easy to create a unique and attractive display that is also a handicapped accessible bathroom. On a side note, the tax assessor happened to stop by about a month later looking to raise the taxes a bit for the "new bathroom." But since it never got built he really couldn't. And when he was informed that a bathroom and kitchen had been removed, and that the taxes should actually be lowered, the made a quick exit.

            yeah...  it can suck... been there....

            this is for a little cafe' grill, internet,  local gathering place for an urban area that is really getting new life...  I know better than to get back in this type business  but... it's been a black juke joint for some 30yrs... and the guy can't pay his rent... (to me) and the area just isn't what it was when he could pay...  

            it's my building and i have everything to open and someone who will (run it)... and it's time i put some money back into the building anyway...  so new plumbing  new electric service new kitchen new hvac ect...   it's on slab and i have room so i'm just going to add 10-12ft onto the back of the building and build new restrooms and a walk-in cooler

            yeah  i know better but....

            you can check out Architectural Graphic Standards. They have several different handicapped restroom layouts. Best off finding the book in a library because it's a $250 book.

            ment to carry my tape into a new exxon bathroom today  :)

  4. FNbenthayer | Jun 03, 2008 04:14am | #5

    You need 32" of clearance, i.e. knuckle to knuckle for a person in a wheelchair, 3-0 door makes it easy.

    Are you sure about the 36" stall?

    We do 36" stalls for ambulatory & 60 " stalls for ADA.

    Then you have TP dispenser location, grab bars, sanitary napkins, the flushing handle must be to the wide side of the stall.

    Flood rim must not exceed 34" for the lav with 27" clearance underneath.

     

    1. ponytl | Jun 03, 2008 06:26am | #9

      i'm never sure... just what i read on an ADA website...  but who knows... around here as long as you try to comply they are pretty cool if "it just can't be done"  but in this case i'm adding about 10ft on the back of a small commercial building just so it can have new restrooms for a small grill/internet coffee shop... like i need another project

        Heres four different arrangements that will meet the ADA requirements. These are CAD blocks supplied by Chief Architect. I've surrounded them with 4" walls to help define the minimu area. No fixture can encroach into the defined areas. Note that there are dotted lines that show the clear area needed to meet the minimum ADA.Edit: it looks like I goofed on the right turn layout. Also, if you blow up the PDF to 100%, it should be 1/4" to 1' scale Bob's next test date: 12/10/07

    or here:

    Hope that helps.

    The library should have a copy of Architectural Graphic Standards. It will have layouts and locations for all the toilet accessories.
