From standard units to luxury trailers — we have the right solution for every project and event in Colma, CA
Have a job site, outdoor project, or casual event that just needs a basic, functional unit?
Our standard portable toilets are cleaned, stocked, and ready to drop. We handle delivery, placement, and pickup — you focus on the work.
Not every event calls for a basic porta potty. Some situations demand something better.
Our luxury restroom trailers include climate control, flushing toilets, running water, and interior finishes that match the event. Nobody will know they're not inside.
Events move fast. Restroom logistics shouldn't slow them down.
We calculate unit counts based on attendance, duration, and alcohol service. You get the right number of units without guesswork or mid-event shortfalls.
ADA-compliant units aren't optional — they're a requirement for most permitted events and job sites.
Our ADA porta potties provide the turning radius, grab bars, and space required by code. Available as standalone units or alongside standard rentals.
Job sites have specific needs. Volume, durability, and compliance matter.
We offer flexible scheduling for long-term construction rentals. Weekly service, multi-unit setups, and on-call delivery for active builds.

The number of guests and hours of use directly affects how many units you need. A 4-hour event for 100 people needs fewer units than an 8-hour one.
Check your drop-off surface.
Units need a flat, stable surface. Gravel, asphalt, and packed dirt all work. Soft grass or steep slopes may require a call ahead.
Confirm permit requirements.
Some municipalities require permitted facilities for public events. We can advise, but confirm with your local office.
Ask about hand-washing stations.
Many events benefit from standalone portable sinks alongside restroom units.
Book early for peak weekends.
Spring through fall books out fast in Colma — especially for Saturday events.
One of the most common questions we hear: "How many units do I need?"
The general rule for events: one standard portable toilet per 50 guests for a 4-hour event. Extend that to 8 hours and you'll want roughly one per 35–40 guests. If alcohol is being served, those numbers go up — faster usage means units fill up more quickly.
For job sites, OSHA guidelines recommend at least one unit for every 20 workers on sites with shifts of 10 hours or less. Larger crews, longer shifts, or remote access situations often call for more.
Construction timelines also vary. A unit that works fine for a 3-person crew for a week may not be adequate when you bring in subcontractors.
At A2 Portable Toilets, we help Colma, CA customers size their rental correctly the first time. We'd rather talk through your situation for five minutes than have you stuck with too few units on the day of your event.
