A monthly porta potty rental usually costs $150 to $300 per unit for a basic model in most parts of the U.S. This price often includes weekly cleaning, waste removal, toilet paper, and basic service. High-end units, like ones with sinks or flush toilets, can run $300 to $600+ per month.
That simple range hides a lot of detail. The real price depends on where you live, how long you need the unit, how often it is cleaned, and what type you choose. A short-term event has different pricing than a long job site rental. Local rules, travel distance, and service level also play a part. Below is a clear look at what shapes the cost and how to plan your budget.
Average monthly price by type
The type of unit you rent has the biggest effect on price.
A basic single unit is the most common choice for job sites. It has a toilet, hand gel, and a small vent. This is the option that often falls in the $150–$300 per month range.
A unit with a sink costs more because it needs water tanks and extra service. These often run $250–$400 per month.
A flushable unit or one with foot pumps costs a bit more than the basic type, often $300–$450 per month.
An ADA unit is larger and made for wheelchairs. It needs more space on the truck and costs more to clean. Expect $250–$450 per month.
A trailer restroom with real sinks, lights, and mirrors is closer to a small bathroom on wheels. These can cost $600–$1,500+ per month, based on size and features.
What is usually included in the price?
Most monthly rentals include the core needs so you do not have to manage the unit yourself.
This often covers delivery, pickup, and weekly cleaning. The cleaning visit includes pumping waste, wiping down the inside, restocking paper, and adding hand gel or soap. The tank chemicals are also part of the service.
Some companies include damage coverage for normal wear. Others may charge if the unit is broken or badly damaged.
Always check how many cleanings are included. Weekly service is common for job sites. Busy sites may need more.
What can raise the cost?
Several things can push the price higher.
Location matters a lot. Big cities and remote areas both cost more. In cities, labor and fuel are higher. In rural areas, long drives add fuel and time.
Service level is another factor. If you need cleaning two or three times a week, the price can rise by $50 to $150 per extra visit each month.
Rental length also plays a role. A one-month rental often costs more per month than a three or six month deal. Longer rentals can lower the monthly rate.
Site access can change the price. If trucks cannot reach the unit easily, extra work may be needed.
Time of year also has an effect. Spring and summer are busy seasons for building work and events, so prices can be higher.
Extra fees to watch for
The base price is not always the final bill.
Some firms charge a fuel fee if your site is far from their yard.
There may be a setup fee for hard ground, stairs, or tight spots.
If the unit is moved by someone on site, a relocation fee may apply so the company can find and service it again.
Damage that goes beyond normal use can lead to repair fees.
If the unit is tipped or filled with trash, cleaning fees may be added.
Ask for a full price list before you sign.
Monthly rental vs. weekly rental
A monthly plan is best for long projects like building work, road repair, or large farm sites.
Weekly or daily rentals cost more over time. A unit that costs $120 for one week can reach $480 or more in a month.
With a monthly plan, you lock in a lower rate and steady service. It is easier to plan your budget and avoid repeat booking fees.
For events that last one or two days, short rentals still make sense. For anything over three weeks, monthly is often cheaper.
How many units do you need?
This also changes your total cost.
A common rule for job sites is one unit for every 10 workers for a 40-hour week. Add more units if workers stay longer hours or if there is no break room with toilets.
More units mean higher cost, but too few units cause lines and poor hygiene, which can slow work and upset staff.
Some firms offer small price cuts if you rent many units at once.
Tips to keep the cost down
You can lower your bill with a few smart steps.
Book early, mainly in spring and summer. Late orders can cost more.
Ask for long-term rates if your job will last over two months.
Keep the unit in one spot so there are no move fees.
Place it where the truck can reach it fast.
Stick to basic models if a sink is not needed.
Ask if nearby jobs are already being serviced. If the truck is already in your area, fees may drop.
A simple cost example
Here is a rough example for a small job site.
One basic unit: $220 per month
Weekly cleaning: included
Delivery and pickup: included
Fuel fee: $20
Total: about $240 for the month
Add a sink unit and two cleanings per week, and the same site may pay $380–$450 per month.
Final thoughts
A monthly porta potty rental is usually affordable, simple to set up, and easy to manage. Most people pay between $150 and $300 for a basic unit, with higher prices for added features and service. By knowing what affects the cost and what is included, you can avoid surprise fees and choose the right option for your site.
