The most common construction material for Porta Potties is polyurethane plastic. This material is preferred because it’s easy to make and clean. Some manufacturers create their portable bathrooms with HPDE, a recyclable material and environmentally friendly. Although different manufacturers might have slightly varying steps for making their portable restrooms, here is the baseline guide. The process starts with heating the plastic pellets until they melt. Additives like colorants and UV protectants are mixed into the plastic The resulting material is put through rollers which press it into sheets that are cut to a specific length and width At this point, the plastic sheet could be reheated and put into a mold to be vacuum pressed for some time. This creates the panel units. Other parts of the Porta Potties, like the cleats and toilet paper dispensers, can be created utilizing CNC machines or injection molding. Holes are drilled into the panels, and the units are assembled in the desired form. The newly created portable restrooms are inspected, clean, and prepared for shipping to the market.
