How many people can a 4 stall restroom trailer handle?
A 4 stall trailer covers moderate crowds better than portable toilet rental alone, and it beats hauling in two separate restroom trailer rental units. Construction crews in Federal Way lean on OSHA 1926.51(c) as the baseline: one toilet facility for 20 workers or fewer, then additional seats as headcount climbs past that. Four stalls generally covers a crew in the 40 to 60 range depending on shift overlap. Event planners running a wedding, a festival or a golf tournament often want more stalls than the ratio strictly requires, because guests do not wait in line the way a crew does. If your count is closer to a backyard job, the 2 stall restroom trailer may be plenty. If you are staffing a concert or a county fair, look at the 8 stall restroom trailer instead.

What does a 4 stall restroom trailer cost in Federal Way?
Pricing depends on duration and delivery distance. A day rental sits at the low end of the trailer band, a weekend climbs into the 900 to 3000 dollar range, and a full week runs from 150 up toward 1650. Multi-day construction jobs usually save money against renting four separate standard porta potty rental units once you add up daily rates.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event | 2499 | 3500 | 3899 |
Delivery adds a separate fee, generally 100 to 500 dollars depending on distance and site access. Federal Way Porta Pros also serves Milton, 6.6 miles south, and Des Moines, 7.0 miles north, at the same delivery structure. Check the restroom trailer rental cost page for how weekday jobs compare against weekend event pricing, and see porta potty rental cost if you are still deciding between a trailer and standard units.
Is a 4 stall trailer ADA accessible?
Not automatically. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent be accessible, with a minimum of one unit regardless of cluster size. A 4 stall trailer with a dedicated accessible stall needs a 36 inch clear route per ADA Standards 403.5.1, a 32 inch door opening per 404.2.3, and a 60 inch turning circle inside per 304.3.1. Ramp slope cannot exceed 1:12 under ADA Standards 405.2. If accessibility is a hard requirement for your Federal Way event, ask about it before delivery rather than after setup. Federal Way Porta Pros can also pair a standalone ADA accessible porta potty alongside the trailer if the unit itself is not fully compliant, and the ADA restroom requirements page walks through the full standard.
Water and sanitation matter beyond the stall count too. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and 29 CFR 1910.141(d)2 requires soap and towels or a hand drying device, not hand sanitizer alone, at washing stations. If your crew works with paints, coatings or similar contaminants, 1926.51(f)(1) applies to the washing setup specifically. A handwashing station rental or portable sink rental fills that gap cleanly alongside the trailer. For construction sites juggling dumpsters, fencing and sanitation together, the construction site services page covers the full setup, and general trailer specs live under restroom trailer rental, the pillar page for this unit.
How long does delivery and setup take?
Setup timing depends on site access and distance from Federal Way. Confirm your delivery window when you request a quote, since access, grading and hookup needs vary by site.
Can I upgrade to a luxury trailer for a wedding?
Yes. The luxury restroom trailer line offers finish upgrades over a standard 4 stall unit. Check wedding restroom rental for event-specific guidance on stall count and placement.
Does the trailer need a power hookup?
Most units run self-contained or connect to standard power. Ask about your site's specific hookup needs when you call, since some sites need a temporary power pole added.
What is the difference between 2, 4 and 8 stall trailers?
Stall count scales with headcount and event length. Compare the 2 stall restroom trailer and 8 stall restroom trailer pages directly against this one before booking.
