Medium Composting Toilets for Vans & Compact Spaces: The Trelino® M

The Trelino® M Series: Three Personalities, One Perfect Size

Finding the ideal dry separating toilet often leads straight to the Size M. Why? Because it represents the "golden middle": compact enough to fit almost any van, yet large enough to provide full seating comfort. In this category, we present our three flagship models: Origin, Evo, and Timber. Three distinct concepts with one shared goal: making your mobile life self-sufficient and chemical-free.

Design Variety – A Match for Every Build

Every camper conversion is unique, which is why our M series offers the perfect choice for your specific needs. Whether you are looking for an ultra-lightweight setup for your micro-camper or an elegant solution for your tiny house:

  • Trelino® Evo M: The modern lightweight made from recyclable plastic for maximum hygiene and easy cleaning.

  • Trelino® Origin M: The robust classic made from hard-wearing polyethylene and features a stylish wooden lid.

  • Trelino® Timber M: The premium design piece with a furniture-style finish for a cosy, high-end atmosphere.

The models in the Trelino® M series are specifically designed to be mounted on a raised platform. By combining the toilet with a base, you achieve an optimal, comfortable seating height while perfectly utilising the valuable storage space underneath.

Maximum Independence for Couples and Solo Travellers

Our Size M separating toilets offer the ideal balance between capacity and space requirements. They are the premier choice for anyone wanting to stay off-grid and self-sufficient for several days without having to constantly hunt for disposal stations. With the Trelino® M collection, you are choosing a sustainable, chemical-free alternative that perfectly blends functionality with aesthetics.

Why the Trelino® M Collection Will Transform Your Van Life

Whether you choose the Evo, Origin, or Timber – the M series brings true freedom to your travels:

  • Odour-free Travel: By consistently separating liquids and solids, the air in your camper stays fresh.

  • Easy Handling: Intuitive emptying and effortless cleaning without the need for a water connection.

  • Durable Quality: Engineered in Germany to meet the highest standards of durability and ergonomics.
