These single-unit, portable bathrooms are by far one of your cheapest options for a porta potty rental. Since they only have relatively small holding tanks – approximately 50-70 holding capacity – they’re mainly ideal for short-term events. Also, they are typically used in concerts, parties, construction sites, or outdoor gatherings. Additionally, these standard porta potties come with a secure lock. Most of them, however, don’t usually have a sink or a flushing system. Depending on your rental company, some regular porta potties provide additional features like hand sanitizers, mirrors, and lighting, too.
