A restroom trailer is a small building on wheels with flushing toilets, running water, lights and climate control. A luxury porta potty, also called a deluxe flushing unit, is a single stall with a foot-pump flush and sink. Trailers need power and water. Deluxe units need no hookups and fit tighter spots.

Both options are a step up from a basic porta potty. The right choice depends on your guest count, your site and your budget. This side-by-side comparison helps you pick.

What is the difference between a restroom trailer and a luxury porta potty?

The main difference between a restroom trailer and a luxury porta potty is size and setup. A restroom trailer has 2 or more private stalls with real sinks, mirrors and lighting. A deluxe flushing porta potty is one stall with a foot-pump flush, a small sink, paper towels and a mirror.

Does a restroom trailer need power and water?

A restroom trailer needs power and usually water. Plan for a standard 110V outlet, with a dedicated 20-amp circuit recommended, within reach of the trailer. The trailer also needs a garden-hose water source or an onboard tank. A deluxe flushing porta potty needs no power or water at all.

If your venue is a field, barn or beach with no outlet, a generator or deluxe units are the practical choices. Ask about power when you call so the quote matches your site.

Never run a restroom trailer on a long, thin extension cord shared with a caterer or band. A dedicated circuit keeps the lights, fans and pumps running all night.

How much space and access does each one need?

A restroom trailer needs a long, level spot and a clear path wide enough for a truck and trailer to back in. A deluxe flushing unit needs about a 4 by 4 foot spot and a gate about 52 inches wide. Steep driveways, soft lawns and tight turns favor deluxe units.

Restroom trailers have entry steps. Plan a firm, lit path to the door. For yard layout tips, read where to place a porta potty.

How many guests can each option handle?

Guest count decides most restroom choices. For deluxe flushing units, plan 1 unit per 50 guests for events up to 4 hours. Use 1 per 40 guests for 5 to 8 hours, and add 1 if alcohol is served. Restroom trailers are matched by stall count, so share your guest list and hours.

That sizing method is our recommendation, not a law. Use the how many porta potties do I need guide to run your numbers.

  • 50 guests, 4 hours, no alcohol: 1 deluxe unit.
  • 100 guests, 4 hours, with alcohol: 3 deluxe units.
  • 150 guests, 6 hours, with alcohol: 5 deluxe units, or a restroom trailer sized by quote.

Which is better for a wedding?

A restroom trailer is better for a wedding when you have power, water and a level spot. Guests get a real bathroom with lights and climate control. Deluxe flushing units are better for remote sites, tight yards and smaller budgets. June to September wedding Saturdays book up 1 to 2 weeks ahead.

Many couples pair a trailer with a few standard units near the dance floor. See wedding restroom rental and restroom trailer rental for setups.

Do you still need a wheelchair-accessible unit?

A wheelchair-accessible unit is still needed in most cases, because restroom trailers have steps at the door. Add at least 1 ground-level wheelchair-accessible unit near the trailer. The ADA 2010 Standards, section 213.2, call for at least 5% of clustered portable units to be accessible.

Read the ADA 213.2 text and see our wheelchair-accessible porta potty rental.

Can a restroom trailer go in my backyard?

A restroom trailer can go in a backyard if the truck and trailer can back in and the spot is level. You also need a 110V outlet nearby and a garden hose or onboard tank. Send photos of the path with your quote request.

Is a restroom trailer wheelchair accessible?

Most restroom trailers have entry steps, so a wheelchair user may not be able to get in. Add a ground-level wheelchair-accessible porta potty near the trailer so every guest has a restroom they can use.
