How Many Stalls Does a 4 Stall Restroom Trailer Have?
Four stalls, plain and simple, split evenly or with one side larger depending on the trailer. That is enough for a mid-size wedding, a corporate 5k, or a construction crew that has outgrown a bank of standard porta potty rental units. Compare it against the smaller 2 stall restroom trailer if your guest count is under 75, or step up to the 8 stall restroom trailer once you cross 300. Every unit runs on fresh water and holds waste in an onboard tank, similar in concept to the 60 to 70 gallon tank on a standard porta potty rental unit, just scaled up for higher use. If you want climate control and finished interiors instead of a bare-bones layout, look at the luxury restroom trailer line, and if showers matter more than toilets, the shower trailer rental page covers that separately. For general planning math, how many porta potties do i need walks through headcount ratios that also apply to trailers.
What Does a 4 Stall Restroom Trailer Cost in Largo?
Pricing depends on how long you need it and whether delivery involves a longer haul. Largo Porta Pros quotes trailers by the day, week or event, and weekend rentals typically run a flat rate rather than a per-day multiple.
| Duration | Typical Range |
|---|---|
| Day | $175 to $2,500 |
| Week | $150 to $1,650 |
| Event (multi-day) | $2,499 to $3,899 |
A weekend booking commonly lands between $900 and $3,000 depending on trailer size and site distance. Delivery adds a separate fee, and a roll-off style delivery for a trailer this size needs about 60 feet of straight clearance behind the truck to position it safely. Full cost breakdowns, including delivery and pump-out cycles, live on the restroom trailer rental cost page, and general per-unit pricing across product types is on the porta potty rental cost page. If your job is short-term, check porta potty rental per day for comparison against standalone units.
Is a 4 Stall Restroom Trailer ADA Compliant?
Not automatically. Standard 4 stall trailers are built for guest volume, not accessibility, so if you need a wheelchair-accessible stall you should request one specifically or pair the trailer with a dedicated ADA accessible porta potty unit. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, be accessible. That standard also calls for a 60 inch turning circle under section 304.3.1 and a 32 inch clear door opening under section 404.2.3, specs most standard trailer stalls do not meet without modification. For full guidance, see ada restroom requirements. Largo events at parks or venues open to the public should plan for this ratio rather than assume the trailer alone satisfies it. Construction crews working under OSHA also need toilet counts to match crew size under OSHA 1926.51(c)(1), which sets ratios starting at one facility for 20 workers or fewer, so a 4 stall trailer may need supplementing on larger sites; see osha portable toilet requirements for the full table.

How far in advance should I book a 4 stall restroom trailer?
Book two to four weeks out for weddings and festivals, sooner during peak spring and fall event season in Largo. Construction jobs can often get faster turnaround. Delivery scheduling depends on site access and distance, so confirm clearance and timing when you request a quote.
Does the trailer need a power hookup?
Most 4 stall trailers run on a standard outlet or built-in generator for lighting and climate control. Confirm power needs when booking, especially for multi-day events where continuous AC matters. Ask Largo Porta Pros about generator options if your site has no accessible outlet.
How often does the trailer get serviced during a multi-day rental?
Service intervals depend on usage, but ANSI/PSAI Z4.3 sets a baseline of one visit per week for moderate use. High-traffic events often need daily servicing instead. Discuss your expected headcount so the schedule matches actual demand.
Can I place the trailer on grass or gravel?
Yes, as long as the surface is level and can support the trailer's weight without sinking. ADA Standards section 302.1 calls for stable, firm, slip-resistant surfaces, a good baseline even for non-accessible units. Confirm ground conditions before delivery day.
What is the difference between this and renting several porta potties?
A 4 stall trailer offers sinks, interior lighting and a more finished feel than a row of standalone units. Standalone portable restroom rental units cost less and set up faster for smaller or shorter events. Choose based on guest expectations, budget and site space.
