The unit is composed of a minimum of materials. Utilizing stainless steel structure means that the Portland Loo weighs a fraction of a typical restroom and can be delivered on site as a complete enclosure. The restroom can be quickly removed during flood conditions or easily repaired onsite with its modular design. With a cleaning hose and janitorial supplies stored in the mechanical closet and protected with a anti-graffiti clear coat the restroom is easy to maintain. The Loo’s in Portland are available 24/7, taking the strain off local business and creating a welcoming environment for families.

Louvers at the top and bottom of the wall create an interior environment that offers complete visual privacy, while remaining as connected with the outside as possible. The lower louvers are angled to provide law enforcement the opportunity to observe the number of users within the unit without compromising privacy. The unit’s hand-washing station is mounted on the exterior to promote shorter use times and to serve the general pedestrian population. At night a gentle light washes the exterior until occupied, at which time the interior lights activate and the exterior lights dim, announcing that it is in use.
