Where can a restroom trailer be placed?

The great thing about restroom trailers is that they are mobile and can be placed almost anywhere. There are a few things we want to avoid when placing, or parking a restroom trailer. First, restroom trailers are not allowed to be placed on public streets, alleys, or sidewalks without approval or permission from the local municipality or authority. Second, mobile bathroom trailers are very heavy, especially when the tank is full of water and/or waste. So we make sure the landing surface is either paved or compacted. If necessary, we can place blocks under each support leg to prevent ground sinking and/or damage to the surface. Third, the space where the restroom trailer is parked must be in space for our trucks to maneuver in-out and be accessible on both sides of the trailer. This is important because the backside of the unit is where the mechanical components are located. In the unlikely event of a water or power issue, our technicians must be able to access the service door. So parking up against a wall or a fence is okay as long as there is a greater 5-foot distance between the restroom trailer and fixed divider (wall or fence).

How much do portable restroom trailers cost?

Just like anything most things, it depends. However, you should expect to pay $800-$8000 to rent a portable restroom trailer. On the lower end ($800) this would be for a single-day mid-week rental of a 2-station bathroom trailer. On the high end ($8000) would be a month-long commercial rental for a 9-station luxury restroom trailer. So it depends on the size of the trailer, the duration of the rental, and the season. Depending on whom you rent from their inventory will also be reflected in the price. The size of the trailer is the single largest factor in price. The larger the restroom trailer the higher the prices. And depending on how long the bathroom trailer rental will be needed (night, day, weekend, mid-week, week, or month) will influence the price. However, the longer you rent the portable restroom trailer the cheaper your average daily rate will be. Lastly, seasonality is something that can drive the cost of a restroom trailer rental. For those summer and winter months there aren’t many events, so companies will rent the restroom trailer out for less. But during those peak wedding season months of fall and spring, prices historically have surged and are known to double.

How do I keep my restroom rental maintained during an event?

Luxury restroom trailers are simple to maintain and require little to no effort by those who rent a portable bathroom trailer. The three biggest things are: power, water, and supplies. The Lavatory luxury restroom trailers have air conditioning and heating units installed in them and require a dedicated 20 amp service. Typically a washing machine, home refrigerator, microwave, etc., are plugged into a 20A. They look like your standard 3-prong plug but one receptacle shaped like the letter “T.” Please work with your Lavatory luxury restroom trailer technician to find a dedicated 20A service. The trailer cannot be parked more than 100’ from where it’s plugged in. This will ensure that the heating/cooling and lights operate properly. Each portable restroom trailer can be connected to the city or local water with just your average ½” garden water hose. Similar to the power, this cannot be further than 100’ away from the restroom trailer. In the unlikely event it does, each trailer is equipped with a 200-gallon freshwater tank that can be filled on site. Lastly, keeping the luxury restroom trailer stocked with supplies is an absolute must. Each trailer is clean and fully stocked with supplies to accommodate single-day events. Additional supplies (toilet paper, towels, soap, etc.) can be found under the sink of both the men's and women’s stations.

What chemicals do you put in a portable toilet?

The Lavatory luxury mobile restrooms use a sophisticated pump and filtration system similar to those found in airplanes. This means the use of chemicals is limited. The only thing that we put in our tanks is scent tablets to help eliminate odor. They are used also for RVs and marine use. They are safe for all septic tanks and completely biodegradable, the drop-ins are made with an ultra-concentrated formula that does not contain the toxic, formaldehyde-releasing ingredient bronopol. Other than that, we use basic household chemicals to clean and sanitize the restroom trailers. We use a variety of products including bleach, multiple-purpose cleaner, and glass cleaner. Our luxury portable restroom trailers have Meyers brand hand soap and Purely hand sanitizer. Lastly, for extra freshness, each bathroom trailer has an automatic air freshener that sprays a pleasant smell into the air every 15-30 minutes.

Can portable toilets be used in hot climates?

It's much better and easier to have a portable restroom trailer than porta potties in hot climates. Each of The Lavatory luxury restroom trailers is equipped with an independent air conditioning system. The thermostat is located in the service room and is only accessible to our technicians. We do our best to keep the restroom trailer at a comfortable 68 degrees Fahrenheit. If you have a specific temperature request please let the technician know. Another thing to consider is the steps and handrails to get in and out of the trailer are also metal. When exposed to direct sunlight they can get very hot. So please be cautious when using the entry and exit hardware of a portable restroom trailer.

What are temporary restrooms for long-term rentals?

Long-term portable restroom trailers have exclusive commercial pricing and specific requirements. Having a restroom available to your employees and customers is typically required by most local city, county, and state government regulations. In the unexpected event, something happens to your onsite facilities, a temporary restroom in the form of a portable bathroom trailer rental can immediately accommodate your needs and requirements. Repairing a commercial restroom can be time-consuming and frustrating ordinal. But renting a temporary restroom trailer for short-term or long-term periods doesn’t need to be. Depending on the number of employees or expected customer use, we can help you determine what size luxury portable restroom trailer will accommodate your needs. Once the site has been determined for the presented use cases, identifying the parking location onsite will be the next challenge. Typically for long-term restroom trailer rentals, we tap directly into the local sewage. Where onsite sewage is not available to the bathroom trailer, we will schedule a local third-party pump service. The schedule and number of pumping services necessary will be determined by the portable restroom trailer’s usage frequency. All associated pump servicing fees are passed directly onto the customer. Along with sewage, the restroom trailer will be connected to onsite water and power. These hookups cannot be further than 100’ from the trailer. The bathroom trailer does have locks for security purposes. However, our preference is that the restroom trailer is enclosed in an area that is fenced off from public access. When securely enclosing the luxury restroom trailer isn’t possible, onsite security may be required or other arrangements may need to be made.

What is included in your restroom trailer price?

Customers just want to know what the bottom line price is. The Lavatory luxury mobile restrooms believe in offering flat rate no-nonsense pricing on all our portable bathroom trailers. The single price you’re quoted from The Lavatory is all you’ll ever pay for your restroom trailer rental. After providing the base rate, most of our competitors will add additional fees. Some of these fees can include taxes, sewage, sanitation, delivery, transportation, setup, administration, etc. All these fees can become exhausting and drive up the original base rate. The Lavatory includes all of this into a single, including taxes. Once the restroom trailer is delivered and set up, you’ll be completely stocked with paper products. This includes toilet paper and paper towels. Sanitation supplies, soap, and hand sanitizer will be topped off. Extra supplies can be found underneath each vanity on both the men's and women’s sides. Additional supplies may be found in the maintenance closet on the backside of the restroom trailer. The only exception here is for a long-term restroom trailer rental. Long-term is any temporary bathroom trailer rental lasting one week and longer.

Where will the luxury portable restrooms be set up?

Deciding where to place the portable restroom trailer needs identified before delivery. Several things need to be considered before setting up. The primary thing to consider is where the bathroom trailer will be parked. Once the portable restroom trailer is placed it cannot be moved. The surface area needs to be flat, cemented, or impacted enough to hold up 25,000LBS. The ideal location for setup is patios and driveways. The secondary considerations are the distance from power and water. The mobile restroom trailer cannot be parked further than 100’ from the power and water sources. The trailer’s powered services need a dedicated 20 amp service to adequately power the onsite heating/cooling system and lighting. Anything further than a 100’ run will not provide enough electricity to adequately power the unit. The same applies to the water hookup, if the distance is more than 100’ from the restroom trailer there may not be enough water pressure to service the sinks and toilets. Lastly, and often overlooked is the placement for aesthetic purposes. The bathroom trailer is the last backdrop anyone would want in a photo or be something people have to walk by before getting food. Think about a place where a portable restroom trailer can be easily accessed, but out of the way from everything else that may be going on. No matter where you decide to park the luxury bathroom trailer, a truck needs to be able to get in and out when dropping it off then picking it up.

Restroom Trailer Power and Water Requirements (2026 Guide)

Luxury restroom trailers have become the go-to choice for weddings, corporate events, and construction sites that need something better than the capacity of a Porta-Potty. These mobile units provide flushable porcelain toilets, running hot and cold water in real sinks, LED lighting, ventilation, and climate control.

However, these amenities depend on the trailer’s right power source and water supply. Therefore, it's a must that you understand the restroom trailer power and water requirements before delivery. It will help you plan better and avoid any last-minute hiccups.

Why Do Restroom Trailers Need Power and Water?

A luxury restroom trailer needs both electricity and water because it's built to function just like a real bathroom, with sinks and running water.

Water is needed to run the sinks, toilets, and the pedal flush mechanism. Most restroom trailers use a pedal flush mechanism instead of a handle on a tank like at home. Pressing the pedal with the foot causes fresh water to rush into the toilet. So without water, there's no way to flush or wash your hands.

Power runs everything else. This includes lighting, water pumps, exhaust fans, and climate control (air conditioning/heater). This is what lets you run the air conditioning on a hot day and keeps the trailer interior well-lit and odor-free.

Water handles sanitation, and power provides comfort. Without these two, the trailer will be the same as the standard porta-potty: an unlit, cramped box with a bottle of sanitizer.

At a Glance: Restroom Trailer Power and Water Requirements

Requirement	Specification
Electrical power	20-amp, 110-volt circuits (up to 30–50 amps for larger units)
Electrical connection	Standard household-style outlets
Water connection	Standard garden-hose connection (3/4" spigot)
Water-source distance	Within 75 feet
Trailer placement	Firm, level ground with service access

Restroom Trailer Power Requirements

The circuit must not be shared with refrigerators, coffee makers, food warmers, chandeliers, DJ setups, or other heavy loads. The last thing you want at your event is a tripped breaker that shuts down everything else as well.

A direct hookup to a high-voltage outlet is ideal.

You can use an approved heavy-duty outdoor extension cord if the electricity source is within a reasonable distance. Long power cords can cause a voltage drop. So, always confirm the maximum distance and cable gauge with your rental company.

When There's No Power On Site

Not every venue has an ideal outlet nearby. Heritage sites, waterfalls, farms, open fields, and undeveloped construction sites often have no electrical access at all. In these cases, a trailer can be hooked up to a power generator and work entirely off-grid.

Generators come in gas, propane, diesel, solar, and hybrid varieties. The right choice will come down to how long your event will be, noise restrictions, and, obviously, your budget.

Many portable generators can run continuously for 8 to 12 hours before needing a top-up. A standard 20-lb propane tank can run a generator for 6 to 8 hours of lighting and pump use, while a luxury restroom trailer running full air conditioning for an all-day event will need larger generators.

Some luxury restroom trailers also come with solar panels. They use solar energy to cut down on fuel use and noise problems during long events and extended use.

Restroom Trailer Water Requirements

Interior of a restroom trailer with a toilet, urinal, vanity, and mirrors.

Restroom trailers need a water source to supply the sinks and flushing mechanisms. There are generally two ways to do this.

The first is to connect a standard garden hose to an external spigot or outdoor faucet at the venue. This is the simplest and most reliable method, given the water source is close to where the trailer will sit.

However, if an outdoor spigot isn't available nearby, water tanks and pumps built into the trailer can supply fresh water. No hookup is needed in that case. This is common for remote sites or locations that are entirely off-grid, such as deserts, canyons, and mountains.

How Long Can a Trailer Run on Its Own Tank?

The short answer: it depends on your trailer's tank size, fixture flow rates, guest count, event length, and usage.

Freshwater and holding tanks on standard units typically range from 65 to 400 gallons. They typically cap out around 100 to 500 uses before the trailer needs to be serviced. This is a significant step up from the capacity of a porta potty, which usually holds far less.

The American Restroom Association (ARA) recommends one unit per 50–75 guests for a four-hour event.

FAQs

Do I really need a dedicated circuit, or can I just plug it into any outlet?

A 2-station mobile bathroom rental can run off a standard 20-amp, 110-volt electrical outlet. Larger units with multiple stalls will need a dedicated circuit, sometimes as high as 30-50 amp electrical service. This avoids tripped breakers or strained wiring. We will help you decide which circuit is best suited to run the trailer.

What size generator do I need for a restroom trailer?

That surely depends upon the trailer's electrical requirements. Units running air conditioning, water heaters, and full lighting draw more power than a basic single-stall unit. You can always ask us about the specifications when requesting a quote.

What is a good location on my site for trailer placement?

Look for level ground near available infrastructure. Ideally, the water source should be close to the trailer and within reach of an outdoor faucet or spigot. Also factor in how the trailer and tow vehicle sizes affect access, since delivery trucks need room to maneuver.

How much plumbing and electrical knowledge do you need?

Very little. We will handle the hookup, whether that means connecting a garden hose to an external spigot or faucet, or wiring up a generator. You just need to tell us about your location and available infrastructure in advance. That's it.

Can restroom trailers work at construction sites without utilities?

Yes, completely. A generator can provide the required power, while built-in freshwater tanks can supply water. This flexibility makes restroom trailers a practical choice for construction sites and events where access to utilities is limited.
