What is a 4 stall restroom trailer?
It is a towable unit with four private stalls, each with its own door, sink and flushing toilet, split so men and women get separate sides or the whole thing runs unisex. Compare it against the 2 stall restroom trailer if your guest count is under 150, or step up to the 8 stall restroom trailer for anything past 400 people. For a Davis wedding at a venue with limited plumbing, this size usually covers the reception without a line forming. Some renters want a nicer finish inside; if that is you, look at the luxury restroom trailer option instead of the standard build. Full specs and layouts live on the main restroom trailer rental page, which is the hub this page sits under. If you also need showers for a multi-day event, pair it with a shower trailer rental.
How much does a 4 stall restroom trailer cost in Davis?
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |

Weekly and event rates depend on generator needs, water hookup access and how far the delivery truck has to travel. Full breakdowns with add-on costs sit on the restroom trailer rental cost page, and if a single-stall unit would work instead, the porta potty rental cost page covers that math too. Ask about delivery before you book; a straightforward Davis drop usually costs less than one requiring a long haul out toward Winters, 14.8 miles west, or Monument Hills, 16.0 miles northwest.
Where can a 4 stall restroom trailer be placed on site?
It needs level, stable ground and enough clearance for the tow vehicle to back in and level the unit, similar to the 60 feet of straight clearance a roll-off truck needs for a roll-off dumpster rental delivery. Ground should meet the same stability standard used for accessible routes generally, ADA Standards section 302.1, which calls for stable, firm, slip-resistant surfacing. If your event needs an ADA-compliant stall instead of a full trailer, check the ADA accessible porta potty page; ADA Standards section 213.2 requires at least one accessible unit in any cluster of single-user toilets, and that logic carries over to trailer placement too. Davis venues near UC Davis, 2.9 miles southwest, often have gravel or turf lots that need a walk-through before delivery day. If you are unsure how many stalls or units your headcount actually needs, the how many porta potties do I need guide walks through the ratios, including OSHA 1926.51(c) counts for job sites running crews rather than guests.
Does a 4 stall trailer need power and water hookup?
Most units run fine off an onboard generator and internal freshwater tank for a single weekend, but multi-day events do better with a hookup. Ask about a temporary power pole if your site lacks accessible power. No hookup is required for basic weekend use.
Can I rent a 4 stall trailer for a construction project instead of an event?
Yes. Crews sometimes prefer a trailer over standard units for site morale, but OSHA 1926.51(c) toilet counts still apply based on worker headcount. Pair it with broader construction site services planning so counts and placement both check out before crews arrive.
How far in advance should I book in Davis?
Two to three weeks is safe for a weekend wedding or festival; event-season weekends near UC Davis book faster. Reach out through request a quote early if your date falls during a busy campus event window.
What is the difference between this and renting several porta potties?
A trailer gives private, enclosed stalls with real sinks, closer to indoor plumbing than a standard porta potty rental setup. Guests notice the difference at weddings and corporate events more than at job sites.
Do you deliver outside Davis?
Yes, including El Macero at 4.5 miles east and Dixon at 10.5 miles southwest. Check service areas for full coverage, or browse porta potty rental in Davis for the citywide overview page.
