Size: Origin S

Trelino Origin Composting Toilet

The Trelino® Origin Composting Toilet is a simple, reliable, and sustainable bathroom solution designed for flexibility in any environment. Offered in three convenient sizes—S, M, and L—it provides the right balance of comfort and capacity whether you’re a solo traveler, a couple, or a family on the move. Built with durability and practicality in mind, the Origin series combines a timeless design with user-friendly functionality, making it an excellent fit for camper vans, RVs, boats, cabins, or tiny homes.

The Origin S is compact and lightweight, making it the perfect option for minimal setups and small spaces. The Origin M offers a middle-ground capacity, giving more freedom for couples or individuals who want fewer emptying intervals while keeping portability in mind. For longer adventures or shared use, the Origin L provides the most spacious capacity, reducing the need for frequent disposal and giving you greater convenience during extended trips. With three distinct sizes, the Trelino® Origin ensures there is a composting toilet suited to your unique lifestyle and space requirements.


All models in the Origin line feature a smart liquid and solid separation system that prevents odor and keeps maintenance simple. The removable containers are designed for quick and hygienic disposal, eliminating the need for chemicals, water, or complicated plumbing. This separation system not only improves comfort but also minimizes environmental impact, making the Origin an eco-conscious choice for off-grid living and travel.

Every Trelino® Origin Composting Toilet is crafted for everyday comfort, with an ergonomically shaped seat that feels natural and secure. Cleaning and upkeep are made easy thanks to smooth surfaces and removable parts, while the sturdy build guarantees reliable performance over time. Whether you choose the S, M, or L, the Origin series gives you a dependable, sustainable, and easy-to-use solution for your adventures, helping you travel smarter and live more responsibly.

Trelino Origin Features

  • Area of application: Origin S the perfect portable toilet for a van or tent. Origin M feels particularly at home in the Sprinter van, truck camper, RV or on the boat. Origin L is well suited for installation in mobile homes, RVs, off-grid cabins or tiny houses.
  • Odor neutrality: The separation and drying function of the toilet prevents unpleasant smells.
  • Sustainability: By dispensing with chemicals and water, the Trelino® Origin is environmentally friendly and preserves natural resources.
  • Independence: Without water and chemicals, the Trelino® Origin offers the freedom to travel independently of disposal stations.
  • Hygiene and cleanliness: Individually removable containers allow separate emptying and easy cleaning.
  • Leakage safety: Due to the solid workmanship, the exterior is leak-proof and protects against unpleasant mishaps on the road.
  • Water resistance: The exterior made of polyethylene is water resistant and therefore can also be used in the shower.
  • Stability: With its high-quality, robust body, the Trelino® Origin takes on any adventure.
  • Fan: Due to the short emptying cycles, the Trelino® Origin S does not require the use of a fan. For the Origin M and L, a fan can be installed for even faster drying of the solids. The hole in the separation toilet for the fan must be drilled yourself. We recommend a step drill 1.53 inches.
  • Material: The body and containers of the Trelino® Origin are made of recyclable, acid and chemical resistant polyethylene (PE). The waterproof glued lid is made of multilayer, untreated birch wood.
  • Lid attachment: The lid is fixed by holding magnets, which ensure that the separation toilet always remains well closed.
  • Design: With its stylish wooden lid and shapely curves, the Trelino® Origin will turn your smallest room into something very special.
