What's the benefit of a portable urinal on a construction site?

A portable urinal on a construction site reduces wait times and extends the capacity of your restroom cluster without taking up much space. For your crew of 50 men, OSHA 1926.51 requires a minimum of two facilities, which can be met with one toilet and one urinal or two toilets; you are already providing more than the minimum with four standard units. The main benefit of adding urinals is speed. A crew member using a urinal is in and out much faster than someone using a full toilet, which cuts down the line, especially during peak breaks. This reduces congestion and the wear on your four main units, since most visits are for liquid waste.

In my experience, urinals do justify the cost on a high-use site like yours. They are smaller and lighter than a standard unit, so they fit in tight spots. While you pay for an additional unit, the reduced strain on the toilets can sometimes allow you to extend the service frequency by a day or two if the rental company agrees, offsetting some cost. In Phoenix heat, crews drink more, so the urinals will get heavy use. Just ensure they are placed on level ground with good truck access for servicing.
