How far out is the delivery charge?
Distance costs money. A roll-off delivery needs about 60 feet of straight clearance behind the truck, and Sammamish is far enough that we charge an extra fee on top of the unit rental. Standard units run 100 to 350 dollars per day depending on length of stay; add 100 to 500 dollars for the truck to get there and back. Week and month rentals are better value. Check our current pricing for your exact dates and see how a longer rental stretches the cost across more days.
Sammamish building sites need permits before we place anything in the public right of way. Confirm those rules with the city before you call us. We're familiar with Sammamish work, schools, parks, retail construction, and we know the terrain. Call or request a quote and tell us the job address and duration.
What kind of units work in Sammamish?
Standard porta potties are the backbone. A standard unit holds 60 to 70 gallons and sits about 44 by 48 inches on the ground. Deluxe flushable models cost more but they feel closer to a real bathroom. ADA accessible units meet federal standards: a 60 inch diameter turning circle, 32 inch door opening, and stable slip-resistant flooring per ADA Standards section 302.1. We cluster units for big jobs, and ADA Standards section 213.2 requires at least 5 percent of single-user units to be accessible, never fewer than one.
Restroom trailers handle events and longer builds where workers need hot water, mirrors and stalls. These run 150 to 2500 dollars per day depending on size and features. They need more space than portable toilets but they slash the wear on single units and keep crews happy. Sammamish hosts weddings, corporate events and outdoor festivals, venues like town parks often require trailers instead of portable toilets.
When does a site need multiple units?
OSHA 1926.51(c)(1) sets the baseline: 1 toilet facility for 20 workers or fewer; 1 toilet seat and 1 urinal per 40 workers from 20 up. A 10 person crew needs one unit. Forty people need two. Count your crew and add one extra for comfort, nobody wants a line. A busy construction site 11.9 miles east of Bellevue stays cleaner and moves faster with a service visit every week. See our guide to how many units you need for the math.
Events are different. A 200 person outdoor wedding needs more toilets than a 50 person office party. We size the rental based on duration and crowd. Check OSHA requirements for construction if you're building; for festivals and private events we match capacity to your timeline and guest count.
What about septic and grease pumping?
Sammamish has septic systems. A residential septic tank gets pumped every 3 to 5 years, driven by tank size and household size. A grease interceptor pumps when fats, oils, grease and solids reach 25 percent of the liquid depth. Commercial kitchens in Sammamish restaurants and catering operations call us for that work. Septic tank pumping runs 150 to 300 dollars per service. We handle emergency pumps on weekends too.
Handwashing stations are required on some job sites. Per 29 CFR 1910.141(d)(2), washing facilities must have soap and towels or a hand drying device, hand sanitiser alone doesn't meet code. Learn more about handwashing station rental and placement rules.
How do I reserve a unit in Sammamish?
Call or request a quote with your dates, location and unit type. We confirm the delivery address and any local permit rules. Payment is due before delivery.
What's included in the rental?
One weekly service visit is the baseline per ANSI/PSAI Z4.3. We pump the tank, service the seat and door, restock toilet paper and hand sanitiser, and deodorize. Longer rentals get full service coverage. Short weekend rentals include one servicing.
Can I place a unit in my driveway?
Yes, if you own the driveway. Public right of way placement needs city approval in Sammamish. Check with the city first. We'll help with placement once permits are in hand.
