Shower Trailers

Hot Running Water | Special Events | Disaster Relief

On Site Companies can provide you with a portable shower trailer solution to fit your needs for any occasion. These trailers can offer you the comforts of a hot shower and a clean environment that can be moved anywhere. On Site’s Luxury shower trailer line ranges in size from a two shower unit, to an eight shower trailer. With this range in shower capabilities, the On Site Companies Shower Trailer line can fit any needs you may have.

Special Events

Standard porta potties are perfectly functional and sanitary, but they just can’t provide the comfort and additional features your guests deserve. That’s where portable restroom trailers come in. Depending on how luxurious you want to make your event, you can rent units with mirrors, lights, porcelain sinks, individual stalls, or even marbled walls and countertops!

Corporate Retreats

Some of the most refreshing and fun retreats occur at exotic outdoor locations, but these venues usually don’t have enough facilities for your entire team. Without proper foresight and planning, you may find yourself stuck in the middle of a long line of coworkers waiting to use the bathroom (or worse yet, the nearest bush). Making use of portable restroom trailers is an easy and affordable way to rectify this issue.

Home Remodels

To ensure optimal restroom cleanliness and sanitation, porta potties utilize unique chemicals that quickly break down waste and kill bacteria and germs.

Disaster Relief

Portable toilets are small and easy to arrange. This makes them ideal for spaces where you need as many toilets as possible. You’ll be able to fit more units in a small space, giving your guests the convenience of not having to wait in line.
