Separett Tiny: Small Toilet, Serious Engineering
Separett Tiny was created for people who need a real toilet where a traditional bathroom system is not practical: vans, tiny houses, RVs, boats, cabins, off-grid homes, and other spaces where every inch matters.
It is compact, waterless, urine-diverting, low-energy, and easy to live with. It is also designed, tested, and built for longevity.
And because we believe product claims should be backed by more than nice photos and careful wording, we have put Tiny through tests that look a little unreasonable at first glance.
- We have loaded more than 4,000 lbs on the toilet body.
- We have tested the opening mechanism for more than 40,000 uses.
- We have rattled it like it had just spent tens of thousands of miles traveling down country roads.
Not because we expect anyone to use a toilet that way, but because Tiny is made for real life. And real life in a van, tiny home, boat, or off-grid property is not always gentle.
Designed for Small Spaces, Not Small Expectations
Tiny is the most compact urine-diverting toilet in the Separett family, created for installations where space is limited but comfort still matters. The toilet weighs just 18.7 lbs, has a seat height of approximately 17.3–17.7 inches, and is made from recyclable high-gloss polypropylene. It is designed to fit against a wall and can be secured to the wall, the floor, or both for extra stability.
The idea is simple: make a toilet that feels familiar to use, but works where water, sewage, black tanks, or large bathroom layouts are not available.
That is why Tiny is used in vans, tiny homes, RVs, boats, cabins, and off-grid properties. It is a waterless urine-diverting toilet, which means it separates liquids and solids at the source. This helps reduce odor, makes waste easier to handle, and avoids the need for flushing water.
It is often called a composting toilet, but technically, Separett Tiny does not compost waste inside the toilet itself. It collects and separates waste so each stream can be handled appropriately afterward. That distinction matters, because it explains why Tiny can be compact, hygienic, and easy to maintain without relying on internal composting volume, heat, or stirring mechanisms.
Two Versions, Same Core Idea
Separett Tiny is available in two main versions: one with a urine container and one with a urine tube.
The Tiny with Urine Container is self-contained. It has containers for both solids and liquids inside the toilet, making it especially useful for vans, boats, and other mobile installations where external waste handling is not available. With two users, the solids container typically needs emptying about once a week, while the urine container usually needs emptying about every other day.
The Tiny with Urine Tube is made for installations where urine can be led away to a greywater system, sealed container, infiltration setup, or another permitted handling method. This version is especially practical for more stationary installations where an external urine solution makes sense.
Both versions share the same practical foundation: a compact body, urine separation, a solids container, continuous ventilation, and a design that keeps everyday use as clean and simple as possible.
No Cranking, No Agitator, No Unnecessary Complexity
Many compact “composting toilets” use an agitator or crank. Tiny does not, and that is intentional.
In toilets this compact, effective composting usually requires more volume and higher temperatures than the toilet itself can provide. An agitator also adds a component that comes into direct contact with waste, which can make cleaning harder and increase the risk of mechanical failure. Separett’s approach is different: separate liquids and solids, ventilate continuously, and keep the system simple.
The fan helps remove remaining odor after urine separation and keeps air moving in the space. It is quiet, efficient, and uses only 0.04 kWh per 24 hours, making Tiny suitable for battery or solar operation. The toilet can run on 110–230V power or 12V solar cell / battery power.
That low power consumption is a small detail that makes a big difference when your bathroom is in a van, cabin, boat, or tiny home.
The View Screen: A Small Feature People Notice Immediately
One of Tiny’s most appreciated features is the view screen. The screen covers the solid waste container, and the flaps open automatically when you sit down. That means you do not see the contents of the container during normal use. You only see it when it is time to empty.
It sounds simple, but it changes how the toilet feels to use. A waterless toilet should not feel like a compromise every time you lift the lid. Tiny was designed to feel clean, familiar, and discreet in daily use, especially in small living spaces where the toilet may be only a few feet away from the rest of your life.
That is also why we tested the opening mechanism for more than 40,000 uses.
A clever feature is only clever if it continues working.
The Tiny view screen mechanism was tested for more than 40,000 uses, because daily comfort depends on daily reliability.
Officially Rated for 330 lbs. Tested Far Beyond That.
The official maximum user weight for Separett Tiny is 330 lbs. That is the published rating, and that is the number customers should follow for normal use.
But internal testing is where we push beyond normal use.
In our load testing, we placed more than 4,000 lbs on the toilet body without the body cracking.
This does not change the official user weight rating, and it is not an invitation to recreate the test at home, at a campground, or in a workshop with friends who say “let’s just see what happens.”
The point is not that anyone needs to place thousands of pounds on a toilet.
The point is that Tiny has been designed with strength, stability, and long-term use in mind.
That matters because mobile and off-grid installations are demanding. Vans flex. Roads vibrate. Boats move. Tiny houses travel. Cabins sit through hot summers and cold winters. A toilet in these environments needs to handle much more than careful use in a perfectly level bathroom.
Officially rated for 330 lbs. Internally tested with more than 4,400 lbs on the toilet body without cracking.
Road-Tested Without Leaving the Lab
Tiny was not only tested for sitting still.
We also rattled it like it had traveled through tens of thousands of miles of country roads.
That kind of vibration testing is important because many Tiny toilets are installed in vans, RVs, boats, and tiny houses on wheels. In those environments, the toilet is not just furniture. It becomes part of a moving structure.
Country roads, gravel, potholes, washboard surfaces, and long-distance travel all create stress that a normal bathroom toilet never experiences.
Tiny was built for that world.
Tiny is designed for mobile living, so we tested it like a product that actually has to travel.
Award-Winning Design
Tiny is not only tested for durability. It has also been recognized for design.
Separett Tiny received the European Product Design Award in 2021 in the Sustainable Living / Environmental Preservation / Rural Sustainable Design category.
That recognition fits what Tiny was designed to do: provide a modern waterless toilet for small spaces, reduce the need for flushing water, and make sustainable sanitation more practical in everyday life. The award recognized Tiny as a product that brings together compact design, environmental function, and real usability.
In other words, Tiny is not just strong - It is thoughtfully designed.
Easy Installation, Flexible Use
Tiny is designed to be practical from installation onward.
The toilet has no room temperature requirement and can work in both cold and warm spaces, as long as the installation allows for ventilation. The ventilation can be led through a wall, floor, or ceiling, and the toilet is designed for 1.5-inch schedule 40 PVC ventilation pipe. It can be installed with up to 16.5 feet of ventilation piping and two 90-degree bends.
The urine tube version includes a 6.6 ft urine hose, while the urine container version keeps both waste streams contained inside the toilet. The container version is especially useful when external drainage is not available, while the tube version gives more flexibility when urine can be managed outside the toilet.
This flexibility is one reason Tiny fits so many different lifestyles. It can be part of a polished tiny home bathroom, hidden in a van build, installed in a boat, or used in an off-grid cabin where water and sewage infrastructure are limited.
Clean Handling and Realistic Maintenance
A good waterless toilet should be easy to use, but it should also be honest about maintenance.
With Tiny, solids are collected in a removable container. Many users dispose of the waste similarly to diapers, while others compost it properly afterward. The important point is that the waste is not composted when it is emptied from the toilet. If composting human waste, it should be composted for at least 6 months, preferably 12 months, and handled in a sealed system that prevents leaching and keeps out rodents, insects, and rain.
For the urine container version, the container is removable and should be rinsed after emptying. Separett recommends rinsing periodically with a 50/50 water and vinegar mix to help break down residue and reduce lingering smells.
For the urine tube version, urine can be directed to a greywater system, sealed container, infiltration chamber, or other permitted solution. As always, local regulations should be followed when handling greywater, urine, or composted waste.
This is not magic. It is a well-designed system that works because the basics are handled correctly: separation, ventilation, containment, and responsible emptying.
Built on Decades of Separett Experience
Separett has been designing and manufacturing waterless toilets in Sweden since 1976. Tiny may be compact, but it carries decades of experience in urine-diverting sanitation.
That experience shows in the details: the view screen, the low-energy fan, the container handling, the ventilation options, the compact footprint, the updated urine nozzle, and the absence of unnecessary moving parts inside the waste container.
It also shows in the warranty. Separett Tiny is covered by a 5-year warranty.
A durable toilet should not only survive a dramatic test video. It should make everyday life easier, quietly, for years.
