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.

Portable Toilet Rental for Construction Sites: A Complete 2026 Guide

12 hours ago

Whether the project is a small home renovation or a large commercial build, construction workers always need clean, easy-to-reach restrooms.

And if you have ever managed a construction site, you already know how this goes. A porta potty gets dropped off, and once six or more guys start using it, it gets disgusting. It stays that way for about a week until it's cleaned again. Even worse, the blue stuff they use to clean it just covers the smell of effluent, so it still stinks. Far worse is dealing with a dodgy rental company that is impossible to reach when you actually need help.

Portable toilet rentals for construction sites are not just a box-checking step for meeting OSHA’s sanitation requirements. With good planning, they keep workers productive, help you meet OSHA standards, reduce downtime, and make the job site safer and more professional.

Why Portable Toilets Are a Must on Construction Sites

Most construction sites don't have working plumbing at the start of a project. However, workers still need access to restrooms throughout the day to answer nature's call.

If there are no portable toilets, workers might:

leave the site to find public restrooms
spend more time away from work
create sanitation issues
increase health risks
put the project out of OSHA compliance

Portable toilets offer a temporary restroom option until permanent facilities are ready.

There is also a legal reason why portable toilets are a must.

In most countries, workplace safety regulations require employers to provide accessible bathroom facilities for workers. In the U.S., OSHA's 29 CFR 1926.51(c)(1) law mandates that construction sites provide toilets based on the number of workers on-site.

Technically, you'd call it an “OSHA Standard” rather than a law. But when it comes to OSHA, "standard" basically means the same thing as "law." Failing to follow this “standard” can result in fines, project delays, or even worse, site shutdowns.

OSHA's Table D-1 sets the minimum toilet requirement by headcount.

Number of Workers	Minimum Toilets Required
20 or fewer	1 toilet
21–199	1 toilet + 1 urinal per 40 workers
200+	1 toilet + 1 urinal per 50 workers

A locked/broken, or filthy toilet doesn't count. OSHA has said plainly, in more than one interpretation letter, that an unsanitary toilet isn't "provided". So hitting the right number on paper only doesn't help if half your units are unusable by week two.

You also need to provide handwashing facilities as required by 1926.51(f). Hand sanitizer by itself is not enough if you can set up running water at the site.

There is an exception to this rule, though. Mobile crews do not need an on-site unit if they can reach a proper facility within about 10 minutes. However, most general contractors find it easier to provide portable toilets rather than plan around this rule.

Warning Note: Do not even think about ignoring this compliance. Why? Because in 2025, the maximum fine that OSHA imposed for an other-than-serious or serious sanitation/toilet violation was $16,550 per violation. If the violation was classified as willful or repeated, the maximum penalty increased to $165,514 per violation.

Think about it: would you rather rent a portable toilet for a few hundred dollars a month, or risk paying thousands of dollars in fines?

How Much Does It Cost To Rent a Portable Toilet For a Construction Site

There is no single fixed price for renting portable toilets, and companies that offer you a flat rate without doing any inquiries are merely making an estimate. The actual cost will vary according to:

the kind of portable toilet
the length of time you need it
how frequently it is serviced
the location of your site

Here’s what most contractors can expect to budget for in 2026.

Kind of Portable Toilet	Rental Cost/Per Month
Standard port-a-potty	$100–$300
Flushing port-a-potty	$250–$500
ADA-compliant porta potty	$150–$400
Crane-lift or high-rise portable toilet	$250–$600+
Restroom Trailer	$2500–$5000+

1. Standard Port-a-Potty

A standard port-a-potty is a simple, non-flushing portable toilet mostly used at construction sites. It has a monthly cost ranging from $125 to $275 and includes weekly maintenance. In areas where the cost of living is lower, the prices can be as low as $75 to $150 per month. However, in large cities such as Los Angeles or New York, during periods of heavy construction, the prices can go as high as $300 or above. In Phoenix and other parts of Arizona, portable toilet rental for construction sites falls between $160 and $240.

2. ADA-Compliant Port-a-Potty

These larger units come with ramp access, handrails, and additional space. They tend to cost between $30 and $75 more each month than a standard port-a-potty. When your site employs 20 or more people or when access is required by someone with a disability, you are required to have at least one accessible unit on site.

3. Restroom Trailers

Restroom trailers are not generally found at most construction sites. But you could end up needing them if office staff, inspectors, or clients are frequently there. They are the best option for high-quality hygiene, improved productivity, and workers' privacy. However, they are more expensive (typically three to four times the price of a traditional port-a-potty) since they have a different pump-out procedure. Restroom trailers have a monthly rental cost ranging from $1,500 to $5,000 and include weekly maintenance.

What Is Usually Included in the Rental Price?

A standard long-term construction rental usually comes with the following:

delivery to the construction site
pickup at the end of the rental
the portable toilet unit
weekly pumping and waste removal
cleaning and deodorizing
toilet-paper restocking
basic supplies such as hand sanitizer

Note: Keep in mind that not every quote includes all of these services. Some companies list delivery, pickup, fuel, environmental fees, and waste disposal as separate charges from the main rental rate. So, ask for the total delivered price instead of just the monthly rate.

Frequently Asked Questions

What is the recommended number of portable toilets for a construction crew of 50?

As shown in OSHA's Table D-1, a crew of 50 workers falls within the 21 to 199 worker category and therefore requires one toilet and one urinal for every 40 workers. This would normally amount to about two toilet-and-urinal combination units for 50 people. Several contractors include a third unit if the crew works long hours, there are many subcontractors on site, or the toilets are widely spread and difficult to access. Although OSHA's requirement is only the legal minimum, you may need to provide more portable toilets to ensure that your crew remains comfortable and productive.

Where is the best location for portable toilets on your construction site?

Place the portable toilets on a flat, stable surface so a service truck can access them once a week for cleaning. Ensure that they are close enough to the working area for the workers to use them. But don't position them in the path of heavy machinery, deliveries, or busy walkways. On big sites, distribute the toilets throughout various zones rather than putting them all in one place, so that the workers don't have to walk a long distance. Avoid locating toilets near site entrances, where clients or inspectors will see them first. Last but not least, keep them away from areas where water collects after it has rained.
