    For the areas surrounding the water closets and urinals, what do you accept as "nonabsorbent"?

    TO generalize, I would say for the most part I would accept anything except raw wood and carpet.

    Well, it says hard and nonabsorbent so I would think the intent is to see tile or those fiberglass sheets. I do no think that gypsum board with a good paint is sufficient from experience.

    err are you saying that hypothetically, or did you actually inspect someplace with gypsum floors?

    I thought the question was regarding nonabsorbent-- which I would accept any pretty much any flooring that is not raw wood or carpet.

    If the question is regarding what is acceptable flooring, I think I'd rather start a thread on attic access :)

    He's referring to the wall covering requirement. We kicked this around in the old forum, the answers were all over. We don't except drywall w/epoxy paint. Must be tile, FRP, plastic laminate, metal, masonry, etc. But that's us, I know others had posted they will except the epoxy paint.

    1210.1 Floors; I would agree with TimNY

    1210.2 Walls; We do not accept gypsum board around a urinal period. We will accept it in a single water closet restroom not used by the public.

    I emailed the wall surface question to the Gypsum Association a few years ago, after discussing (ok, arguing) the point with architects; this was GA's reply "As far as I know, gypsum board is not considered to be nonabsorbent. This code requirement is generally referring to the wall surfacing materials such as tile or plastic panels. This is a typical application where water-resistant gypsum backing board is used as a substrate for ceramic tile."

    Notice water-resistant gyp not moisture resistant (green board). Of course, what determines "hard" - hammer blow or finger push? Your interpretation here.

    While on the subject, do your require the floor to extend upwards as required by 1210.1 or do you accept a base material?

    IBC 2006 1210.1 Floors. In other than dwelling units, toilet and bathing room floors shall have a smooth, hard, nonabsorbent surface that extends upward onto the walls at least 6 inches (or 4 inches in 2009 IBC).

    CAL GREEN
    Section 5.407
    Water Resistance & Moisture Management

    5.407.2.2.1 Exterior Door Protection.


    Primary exterior entries shall be covered to prevent water intrusion by using a non absorbent floor and wall finishes within at least 2 feet around and perpendicular to such opening.

    Does the floor width need to span more than the actual width of the door?

    For what I can see, I would draw the door and offset a line 2 feet away in both directions (x,y)

    Any feedback?

    Spot on, at issue is the elimination of "any" openings (cracks, separations) between dissimilar materials and other than smooth surfaces so as not to catch and retain splashes and overspray. Not all of us have directional control as we get older (smiling). Therefore the height and width on either side of the urinal/wc are critical though not always spelled out. Think heavy use facilities such as bars and destinations with public use facilities where regular mopups should but don't always occur.

    Can it withstand the ballpoint pen graffitti test for impact resistent?

    Epoxy paint would comply with IBC 1210.2.2. I have previously seen high gloss epoxy used in several commercial restrooms in LA, including at The Rooftop bar/lounge at The Standard hotel in downtown.

    There is no code requirement in IBC 1210.2.2 for the nonabsorbent wall material to also be graffiti resistant or impact resistant. Damage to any finish is a maintenance issue, when needed, to remain code compliant for non-absorbency.

    Because it is not impact resistent.
