The Technology Behind Separett Waterless Toilets
How Innovation, Materials, and Experience Shape Every Product
At Separett, our mission has always been clear: to make everyday sanitation both sustainable and accessible, without the need for water or complex installations. For nearly half a century, we’ve been perfecting the technology behind waterless sanitation, combining Scandinavian design principles with high-end engineering to create durable and hygienic toilet solutions for homes, cabins, and off-grid living.
The roots of Separett are in precision manufacturing
Decades of Innovation and Improvement
From the beginning, our founders set out to solve a simple problem; how to make sanitation possible where plumbing isn’t. What started as an inventive solution for a Nordic vacation home has grown into a global brand known for pioneering urine-diverting technology and waterless toilet systems.
Throughout the years, we have continuously refined our products, introducing smarter separation systems, improving ventilation efficiency, and creating designs that are both functional and beautifully simple. This long-term dedication has positioned Separett as one of the leading innovators within sustainable sanitation.
Advanced Manufacturing and Materials
Today, Separett is part of the Lundahl & Hall Group, which includes several plastic manufacturing facilities. This gives us unique expertise, and control over the entire production chain, from raw material selection to final assembly.
Our waterless toilets are produced using high-precision injection molding, a method that ensures a smooth, non-porous, and highly durable finish on every surface. Even the toilet frames are made this way, resulting in a product that is easy to clean, hygienic, and built to last. Injection molds are significantly more expensive to produce than rotation molds, but they provide a consistency and surface quality that cannot be achieved otherwise.
In contrast, products made with rotational molding often develop microscopic pores in the plastic. Over time, urine and dirt can fill these pores, causing staining and odors that cannot be removed without damaging the surface. This is why we insist on the higher-cost, higher-quality injection-molded approach. For us it’s a long-term investment in reliability and hygiene.

A Material Like No Other
In our urine-diverting toilets, we use a special plastic compound developed exclusively for Separett. This unique formulation prevents the type of degradation that urine typically causes to conventional plastics. The result is a material that retains its strength, color, and finish year after year, even in demanding off-grid environments.
No other manufacturer uses this material, it is designed specifically for our products and applications, underscoring our commitment to quality and durability at every level. This is why Separett toilets can last for decades.

Continuous Development for the Future
At Separett, we see every toilet as a part of a long-term evolution. Just like any modern product, even the best designs can be improved. Each new generation of our toilets builds upon decades of testing, customer feedback, and technological advancement. Our goal is simple: to continue setting the standard for clean, sustainable, and maintenance-free sanitation for generations to come.
