Restroom Trailer Rental: 2027 Costs and How Many You Need
A 20×20 tent seats about 32 guests at round tables, a 20×40 about 64 and a 20×60 about 96, with nothing else inside. Those numbers use about 12.5 square feet per guest at 60-inch rounds, 11.1 at long banquet tables and 10 for a standing crowd. Below are the counts for every tent we rent from Ferndale across Whatcom, Skagit and Snohomish counties, how to adjust for a dance floor or buffet, and the math behind each number.
What Does a Restroom Trailer Rental Cost in Bellingham and Skagit?
Renting a restroom trailer from BellEvent costs $1,000 a day for the 2-stall and $1,300 a day for the 3-stall, or $2,475 and $2,700 for a week, with delivery added. Trailers are the one thing we price by the day or week; tents, tables and chairs use one price for up to 3 days.
| Trailer | One Day | One Week | Guests, 4 to 6 Hour Event (Planning Figure) | Cost per Guest for One Day |
|---|---|---|---|---|
| 2-Stall Executive | $1,000 | $2,475 | About 100 to 150 | $10.00 to $6.67 |
| 3-Stall Executive Suite | $1,300 | $2,700 | About 150 to 225 | $8.67 to $5.78 |
The per-guest math: $1,000 ÷ 100 = $10.00 and $1,000 ÷ 150 = $6.67; $1,300 ÷ 150 = $8.67 and $1,300 ÷ 225 = $5.78.

What Changes the Price
- Stall count. Going from 2 stalls to 3 adds $300 for a one-day rental: $1,300 against $1,000.
- Rental length. A single day, or a week at $2,475 or $2,700. For 2 to 6 days, ask us: we confirm the price on your quote.
- The drive and the drop-off spot. Delivery is priced by a person for each address. Towing and leveling a trailer depends on the route in and the ground it sits on.
- No outlet in reach. Our generator adds $155 for each day and can power a trailer by itself.
- Extra hand washing. Each trailer bathroom has its own sink. For a food area or a long line, our portable hand-washing sink is $150 and gives up to 245 hand washes per tank.
Three Example Costs
These are examples to show how the numbers combine, not quotes. Delivery and tax are added to each.
| Example | Trailer | Add-Ons | Rentals Total |
|---|---|---|---|
| 80-guest backyard party, 4 hours, outlet on its own breaker near the driveway | 2-stall, one day: $1,000 | None | $1,000 |
| 120-guest wedding, dinner and a bar all evening (8 hours), no outlet within 100 ft | 3-stall, one day: $1,300 | Generator, one day: $155 | $1,455 |
| 200-guest wedding, all evening with dinner and drinks | 2-stall and 3-stall, one day: $1,000 + $1,300 | None | $2,300 |
Why those trailers: an all-evening event runs about 40 to 60 guests a stall, so 120 guests need 2 to 3 stalls: the 3-stall. For 200 guests all evening, the 3-stall alone covers about 180, so both trailers (5 stalls) are needed.
How Many Restroom Trailers Do I Need?
Plan about one stall for every 50 to 75 guests over a 4 to 6 hour event, and fewer guests per stall when food and alcohol run all evening. That’s published sanitation-industry guidance (Satellite Industries, Stahla, United Rentals), and it puts our trailers here:
| Guests | 4 to 6 Hour Event | All Evening, with Food and Alcohol |
|---|---|---|
| Up to 100 | 2-stall | 2-stall |
| 100 to 150 | 2-stall | 3-stall |
| 150 to 225 | 3-stall | Both trailers (the 3-stall alone covers about 180) |
| 225 to 300 | Both trailers | Both trailers |
| Over 300 | Call us | Call us |
The math behind the bands: at 50 to 75 guests a stall, 2 stalls cover 100 to 150 guests and 3 stalls cover 150 to 225. For an all-evening event, the guidance drops to about 40 to 60 guests a stall, so the 2-stall covers about 80 to 120 and the 3-stall about 120 to 180. Both trailers together (5 stalls) cover about 250 to 375 guests for a shorter event, or 200 to 300 all evening.
When to size up:
- Mostly one gender. The line usually forms on the women’s side, so add capacity for a bridal shower or a mostly female crowd.
- Long events. If guests are there for more than 6 hours, use the all-evening column, even if the guest count is modest.
Our trailers are not ADA accessible. If any of your guests need an accessible restroom, plan for one at the venue or from an ADA unit provider, and tell us so we can place our trailer to suit.
Restroom Trailer vs Portable Toilets: Which Do You Need?
Choose a restroom trailer when guests are dressed up, the event runs into the evening, or you’d rather guests didn’t use the house; choose portable toilets when cost matters most or no trailer can reach the spot. BellEvent rents luxury restroom trailers only, not portable toilets, so here is the honest comparison.
| For | BellEvent Restroom Trailer | Standard Portable Toilet |
|---|---|---|
| What It Is | A towed trailer with private single-person bathrooms, men's and women's sides | A single plastic unit over a holding tank |
| Toilet | Flushing | Holding tank under the seat |
| Sink | Running water in every bathroom | Usually none |
| Light, Heat and Air Conditioning | Yes | Usually no light; no heat or air conditioning |
| Hookups | An outlet and a garden hose | None |
| Access | A level spot, an 8 or 9 ft wide route and about 12 ft overhead | Smaller; ask the provider what access it needs |
| Cost | $1,000 or $1,300 for one day | Less per unit; ask a portable toilet company for its price |
| Wheelchair Access | Not ADA accessible | ADA units are made; ask the provider |
Where portable toilets are the better choice: a job site, a long public event where cost per unit matters most, or a spot a trailer can’t reach, such as a field with no level ground or no route 8 ft wide. If you go with portable toilets from another company, you can still rent our portable hand-washing sink ($150) on its own.
Where a trailer earns its price: a wedding, a dinner, or a backyard party where guests are in dresses and suits. Each door opens to a private bathroom with its own sink, and the 3-stall adds backlit mirrors, a sound system and LED lighting inside and out.
What Does Your Site Need for a Restroom Trailer?
Every BellEvent restroom trailer needs an outdoor outlet, a garden hose connection and a level spot, with a route the truck can tow it through. Here are the numbers for each trailer:
| Site Need | 2-Stall Executive | 3-Stall Executive Suite |
|---|---|---|
| Power | An outdoor outlet within about 100 ft, ideally on its own breaker | Same |
| Water | A garden hose spigot within about 100 ft | Same |
| Ground | Level and firm enough for a truck: a driveway, a gravel pad or a flat lawn | Same |
| Route Width | At least 8 ft (the trailer is about 7 ft 3 in. wide) | At least 9 ft (about 8 ft 3 in. wide) |
| Overhead Clearance | About 12 ft under branches and wires (the trailer is about 11 ft tall) | Same |
| Space on site, with hitch and steps out | About 16 x 9 ft | About 22 x 10 ft |
| Weight, Empty | About 3,200 lb | About 4,800 lb |
Power, in more detail. The manufacturer’s spec is a 120 V, 15 A GFCI outlet and up to 100 ft of 12-gauge cord. Trouble comes from sharing: if a freezer, a second AC unit or an inflatable’s blower runs on the same breaker, the trailer can trip it, so pick an outlet with that breaker to itself if you can. If the nearest outlet is too far, our generator ($155 a day) takes its place.
Water. We fill the trailer’s fresh-water tank on site from your water supply, so the spigot needs to work on delivery day.
Placement. Close enough for guests to walk to in the dark, far enough from the dinner tables. Tell us where the tent and tables go and we’ll suggest a spot.
What we do. We deliver the trailer, set it up, fill the water, stock toilet paper and paper towels, and empty the waste tanks at pickup. You keep the trailer tidy during the rental.
Where These Numbers Come From
The guest bands on this page come from published sanitation-industry guidance from Satellite Industries, Stahla and United Rentals: about one stall for every 50 to 75 guests over a 4 to 6 hour event, with fewer guests per stall when food and alcohol run all evening. We turned stalls into trailers with the arithmetic shown above. They’re planning figures, not a guarantee of no line. The trailer sizes, tank sizes and power spec come from the manufacturer’s pages and manual for our two models.
Restroom Trailer Cost Questions
Yes. “Station” and “stall” both mean one toilet room. Our 2-stall trailer has two private single-person bathrooms, one on the men’s side and one on the women’s, and costs $1,000 for one day.
