Portable restrooms have a reputation. Chemical smell. Cramped space. Out of paper by midday. A unit that arrived late and got placed in the wrong spot.
That reputation comes from rentals where the details weren't handled.
Ontime Dumpster Service approaches portable sanitation the same way we approach dumpster rental in Middle River — with schedule commitment and operational follow-through.
Units arrive clean. They're placed where they'll actually be used. Multi-day rentals are serviced on the schedule we agreed to. And when an event or project is done, pickup happens when we said it would.
You shouldn't have to settle for bad portable sanitation. You don't have to.
The biggest factor in a good portable restroom experience is choosing the right unit type. Here's how to match them.
The right choice for: active job sites, outdoor work crews, utility projects, general contractor sites
Capacity guidance: 1 unit per 10 workers for regular use.
The right choice for: longer-term deployments, client-facing job sites, community events.
The right choice for: any permitted event or job site with accessibility compliance requirements.
The right choice for: weddings, private parties, high-end outdoor gatherings in Middle River, MD.
The right choice for: larger weddings, festivals, events hosting 150+ guests.
The right choice for: food service events, health settings, or sites with hygiene requirements.
The right choice for: remote project sites, multi-day outdoor events, emergency deployments.

Base formula: 1 unit per 50 guests for events up to 4 hours.
Adjust upward by 25–30% if: alcohol is being served, event runs 6+ hours, or many children/elderly are expected.
Example: 150-guest wedding + bar = 5-6 units or a luxury trailer.
OSHA minimum: 1 unit per 10 workers for sites with 20+ employees.
Under 20 workers: at least 1 unit if facilities aren't within 5 minutes. Consider gender-appropriate arrangements.
