What Is a 4 Stall Restroom Trailer?
Think of it as a small building on wheels. Four private stalls, running water, real flush toilets, sometimes climate control depending on the unit. It's a step up from lining up standard porta potty rental units along a fence line, and a step below the full luxury restroom trailer setups used for weddings and galas. Eau Claire Porta Pros stocks these for weddings, contractor crews, and multi-day festivals where a dozen standard units would feel like overkill. If you're not sure a 4 stall fits your headcount, the 8 stall restroom trailer is the next size up, and the 2 stall restroom trailer works for smaller gatherings. For a general answer on unit counts, check how many porta potties do i need before you lock in a size. Every trailer we place in Eau Claire still needs somewhere flat and reasonably firm to sit, and ADA Standards section 302.1 calls for stable, firm, slip resistant ground on any accessible route leading to it.
How Much Does a 4 Stall Restroom Trailer Cost in Eau Claire?
Pricing depends heavily on the rental window. Here's the range we see across the measured data:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Multi-day event | $2,499 | $3,500 | $3,899 |
A single day rental can run cheap if it's a quick swap-in, but most weekend weddings and two-day events land in the middle bands. For a broader breakdown across all trailer sizes, see restroom trailer rental cost, and for standard unit pricing by itself, porta potty rental cost or porta potty rental per day covers that separately. If you're renting for a construction stretch instead of an event, monthly porta potty rental pricing is a different table entirely, so don't mix the two when budgeting.
Where Can a Restroom Trailer Be Placed on My Property?
It needs a level pad, decent clearance for the delivery truck, and enough room for guests to move around it without tracking through mud. A roll-off delivery needs about 60 feet of straight clearance behind the truck, and the same rule of thumb generally applies to trailer drop-off in Eau Claire. If the unit needs to serve wheelchair users, ADA Standards section 403.5.1 sets a 36 inch minimum clear width on the route to the door, and ADA Standards section 404.2.3 requires at least a 32 inch clear door opening. Inside, ADA Standards section 304.3.1 calls for a 60 inch turning circle, and ADA Standards section 213.2 says at least 5 percent of clustered units need to be accessible. If you're placing this near a public street or sidewalk in Eau Claire, that spot needs confirming with the city; we haven't verified a specific right-of-way rule to point to. For general layout advice, our porta potty placement guide covers ground prep and clearance in more depth, and porta potty permit requirements walks through what to check with the city before delivery day.
How many people can a 4 stall trailer handle in one day?
There's no fixed number, but four stalls comfortably serve a wedding of 100 to 150 guests over an afternoon. For all-day contractor crews, OSHA 1926.51(c) sets toilet ratios by headcount, so a bigger job may still need a portable toilet rental supplement alongside the trailer.
Does the trailer need a water hookup?
Some units connect to a hose bib if one's nearby; others run fully self-contained with onboard tanks. Eau Claire Porta Pros will ask about your site during the request a quote process to figure out which setup fits.
Can I rent a 4 stall trailer for a construction site?
Yes, though most crews pair it with standard units for daily headcount. See construction site services for how trailers and standard units get combined on active job sites around Eau Claire.
How far in advance should I book for a wedding?
Book as early as you can, especially for peak wedding season weekends. Check wedding restroom rental for planning details specific to ceremony and reception layouts.
Is delivery available outside Eau Claire?
Yes. We reach Chippewa Falls, roughly 11.1 miles northeast, and closer towns like Altoona at 5.1 miles southeast. See service areas for the full list.
