Residential Urinals

[Buelligan]

The IRC states to follow IPC for fixtures not covered. This would apply to urinals. Now the question is based on 419.3 what would constitute "waterproofed with a smooth readily cleanable nonabsorbant surface"? Would painted drywall, greenboard or regular be acceptable? Also They wish to build a plywood divider, would any paint provide the required surface? Do we make him install tile wall 2 feet on ither side and install a metal divider or equivilant? Just looking for some other opinions. Thanks as always guys!

I believe that section is talking about the actual physical install of the fixture...(pipe sizing, heights, distances, etc...) the interior finish, I do not think would be as restrictive in an IRC setting....IMHO...

Stainless Steel, Ceramic Tile, Fiberglass Reinforced Panel (FRP), Epoxy Painted Concrete, Painted Drywall are the basic commercial applications we see in our AHJ. We do not currently accept the painted drywall, or wood, for materials surrounding the urinals, but would consider alternative treatments to these materials.

As for a residential use, my six year old treats our toilet like a urinal, and it is surrounded by painted drywall. I suppose you could either follow the commercial code to a "T" or make a reasonable interpretation that addresses the actual use.

I think you will still find answers all over the place. What is your comfort level? The equalivent is in the IBC....and we had a little bit of conversation on it.

1210.2 Walls and partitions.

Walls and partitions within 2 feet (610 mm) of urinals and water closets shall have a smooth, hard, nonabsorbent surface, to a height of 4 feet (1219 mm) above the floor, and except for structural elements, the materials used in such walls shall be of a type that is not adversely affected by moisture.

Exceptions:

1. Dwelling units and sleeping units .

2. Toilet rooms that are not accessible to the public and which have not more than one water closet.

Ahh, circular logic......gotta love the codes. Looks like they are home free.......cardinal sin, didn't look at the exceptions.

Good post MT

Thanks MT!

MT - Thanks, but that is from the IBC. The Scope 2601.1 in the IRC says to reference the IPC, not the IBC, for fixtures not covered. So therefore 1210.2 would not apply here. IPC 419.3 does not have that exception. :devil Man these codes can be so inconsistant! LOL I agree, it should apply, and that would lead to intent, but the chain does not get there.

Thanks

Point made Buelligan! Not sure why I also made the jump to IBC instead of IPC.

 

[gbhammer]

The commentary for the exception in the IBC and the intent behind the exception should still hold true.

It would be one of the few times that I would allow the use of R104.10 Modifications. I would allow it simply due to the fact that it would be easy to document the reason for allowing the modification. Heck the ICC does it for you.

419.3 is from the IBC. Why the exceptions did not carry over with it I do not know. However as gbhammer pointed out you can still use the IBC through R104.10

P2601.1 Scope.

The provisions of this chapter shall govern the installation of plumbing not specifically covered in other chapters applicable to plumbing systems. The installation of plumbing, appliances, equipment and systems not addressed by this code shall comply with the applicable provisions of the International Plumbing Code .

I would take that to mean you would use the IPC to determine what the requirements for a paticular appliance/fixture would be. This would include the approved standards, DFU requirements etc.

419.1 Approval.

Urinals shall conform to ANSI Z124.9, ASME A112.19.2M, ASME A112.19.19, CSA B45.1 or CSA B45.5. Urinals shall conform to the water consumption requirements of Section 604.4. Water-supplied urinals shall conform to the hydraulic performance requirements of ASME A112.19.6, CSA B45.1 or CSA B45.5.
