9 Prefab Vault Toilet Models To Choose From
Need some inspiration? Zeroing down on a vault toilet design should not be complicated. That is why we have a wide range of prefab vault toilet models to get your gears turning when you are on the hunt for something small and simple. Simply pick the model you need and drop it into place.
Single Occupancy
The perfect unit for small parks, recreational areas, or remote sites that do not get as much foot traffic, our single occupancy prefab vault toilet models offer a great starting point for your designs, especially if you are looking for a low-cost solution. These units are designed for efficiency and durability, making them an ideal choice for locations where simplicity and ease of maintenance are priorities. We also offer site-built single occupancy models with more customization options.
Double Occupancy Units
If your park area receives low to moderate foot traffic such that having a single occupancy unit would most likely result in fairly long queues, our double occupancy models are the perfect choice. Build on these prefab vault toilet models and your visitors will enjoy the convenience of extra capacity, especially during those occasional events or spruce up your waterless structure with a site-built model and the endless options for siding, roofing and more.
Fully Customizable Site Built Options
When your site needs something a little “extra”. A restroom building with character that speaks to its surroundings, perhaps matching a historical structure nearby, choose a site-built option instead of a prefabricated model. Add a building to your site that adds to the experience of the public space.
Single Occupancy
The perfect solution for small parks and trailheads, the single occupancy site-built vault restroom provides comfortability to users in remote areas. Keeping the building footprint at a minimum is a great way to provide these facilities while keeping costs down but despite its size, it comes with as many customizable options as a larger or even a plumbed Romtec structure.
Double & Triple Occupancy Units
For any outdoor space that receives moderate use, a single occupancy restroom building may not serve the public’s needs. Double and triple occupancy units are found most often in popular park settings and typically serve average park sites quite well. These structures also have the same customization options of an upgraded plumbed restroom, concession, or shower building.
4–6 Occupancy Units
Expect more traffic and higher usage in your park or recreational spaces? What you need are vault toilet models that can keep up with the needs of your guests, and our 4-6 occupancy units are a good starting point for your custom design. With a higher capacity and intentional features, you can look forward to delivering smooth service at locations that typically experience higher traffic regularly.
8 – 16 Occupancy Units
If you tend to have large-scale events or your park or recreational space is vast, then it only makes sense to customize these high occupancy vault toilet models, capable of withstanding constant use while offering just enough capacity to shorten the wait times for your guests when nature calls. It is the best investment for ensuring that everyone enjoys a clean and odor-free experience, even during busy periods.
