Standard unit

Basic portable restroom used most on construction sites.

Definition

A standard unit is the basic job-site porta potty. Typical porta potty dimensions are about 44 inches wide, 48 inches deep, and 91 inches tall, with a ~24-inch door. It has a tough exterior, simple interior, toilet (often with a urinal), paper holder, and holding tank. Choose it when function and regular service matter more than finishes. Plan a 4 by 4 foot pad plus hose room; ADA cabins need a larger footprint.
