Modular Restrooms


Many times, businesses and other locations have an immediate need for restrooms but do not currently have any on-site. When this happens, you have three options to solve the problem:

  1. Build additional restrooms into your building using traditional construction
  2. Rent port-a-potties for a monthly cost
  3. Opt for a modular restroom

Modular restrooms are often the most popular option out of these three. Why? First, building an addition requires businesses to dish out tons of money and can take many months to complete. Second, port-a-potties can be costly in monthly rent, plus they are not the most sanitary or comfortable option. Modular bathrooms, on the other hand, are affordable, turnkey solutions that are comfortable and can last you decades of use.

What is a Modular Bathroom?

Modular restrooms are prefabricated buildings with built-in bathroom facilities. They are a fast, affordable, and customizable way to get the restrooms to your location when you don’t currently have one. Since modular bathrooms are pre-designed and pre-built off-site in a controlled facility, they are simply delivered to your location and assembled quickly on the spot. Modular restrooms can save businesses some serious money when it comes to adding a restroom, not to mention have it up and ready to use in a matter of weeks.


  • Pre-assembled with built-in plumbing
  • Quick and easy installation
  • Easily cleaned and sanitized 
  • Weather-proof structure
  • Convenient outdoor restroom option
  • ADA compliant 
  • Customizable to your needs

Portable vs. Permanent Modular B

When it comes to modular restroom facilities, you have two options – portable or permanent. Portable restrooms are predominantly for temporary use. They can be either a restroom trailer or similar portable, relocatable structure. Basically, a supplier will drop off the pre-assembled portable restroom to your location. You will likely rent the unit, which will typically require monthly payments. Then, when you no longer need the modular restroom, the supplier will return to pick up the unit. This is a very easy, convenient, and affordable option for those who need a modular restroom for a specific, short-term purpose.

On the other hand, permanent modular restrooms are structured similarly to traditional buildings. Even though they are prefabricated off-site, they have a permanent foundation and can last your business 30 years or more. A permanent modular restroom would be the best option for those who need a long-term restroom solution and prefer a comfortable, functional building that will sit on their property for years to come.

Common Uses and Locations

Modular restrooms are common among businesses or other locations that do not currently have a restroom facility but need one quickly. Many modular restrooms are located in outdoor locations where people spend a good deal of time, whether for commercial or recreational purposes. Some locations where you can typically find modular restrooms are:

  • Sporting arenas
  • Parks and recreation centers
  • Campgrounds 
  • Summer camps
  • Manufacturing facilities
  • Construction and mining sites
  • Oil and gas refineries
  • Schools and universities
  • Entertainment venues
  • Festivals, concerts, and other outdoor events
  • Street fairs, farmer’s markets, and outdoor shopping centers
  • Amusement parks
  • Rest stop areas
  • Remote offices

Keep in mind that although modular restrooms are commonly used in outdoor or remote locations, some businesses choose modular restrooms as a quicker, more affordable option than traditionally built restroom facilities.

What Features can be Added?

One of the reasons modular restrooms are so appealing is because they can be customized to function and look just like traditionally built restroom facilities. There are endless designs, customizations, and features you can add to your modular restroom to fit your needs. Some available add-on features include:

  • Electricity and plumbing (pre-installed)
  • Handicap accessibility and ADA compl;iance
  • HVAC systems
  • Anti-slip flooring
  • Steel, aluminum, vinyl, wood, stucco, or brick siding + more 
  • Sinks and built-in soap dispensers
  • Exhaust fans
  • Water tanks
  • Toilets, urinals, and built-in stalls
  • Showers with customizable doors
  • Benches
  • Copper water lines
  • Custom shelving or cabinets
  • Lockers
  • Custom lighting
  • Multiple floor plans and layouts
  • And much more 

What is the Lead Time for Modular Restrooms?

Modular restrooms can be designed, prefabricated, and installed at your location in as little as 6 weeks. For larger or more custom modular restrooms, it’s your best bet to give your supplier 10 weeks lead time or more. Compare this lead time to traditional construction for restroom facilities, which can take 6 months or more to finish!

Included in this lead time is:

  • Planning and designing
  • Pre-delivery quality control inspection
  • Delivery and set-up
  • Post-delivery inspection by state and third-party approvals

How Much do they Cost?

The overall cost of your modular restroom depends on several factors. The best way to estimate the total cost is to request a custom quote from a supplier. Some factors that go into determining the cost of your modular restroom include:

  • Size (square footage) and layout
  • Amount and type of add-on features
  • Delivery distance
  • And more

Most modular structures will cost between $30-$200+ per square foot, before customizations. Every supplier will calculate costs differently, so it’s best to get a few quotes to compare.Keep in mind that across the board, you will save about 20-50% when choosing a modular building over a traditional building.
