Ultra-compact urine-diverting dry toilet
Trelino® | Evo S
The smallest and lightest toilet in the Trelino® Evo range, designed for compact spaces where a conventional toilet is impractical.
Evo S separates liquid and solid waste into dedicated removable chambers and provides full internal solids containment — the compostable liner is an aid to emptying, not the primary containment vessel.

NZ Green Sticker / self-containment: the Trelino® Evo S is not a WCTNZ®-supported Green Sticker compliant model. Adding a fan kit does not convert the Evo S into a supported Green Sticker configuration. Where New Zealand self-containment certification is required, WCTNZ® recommends moving to the Trelino® Evo L with the required Fan Kit installation.
Product background
Designed for the smallest spaces
Designed in Germany, the Trelino® Evo S is well suited to campervans, RVs, boats, camping setups and other locations where space and weight are limited and Green Sticker certification is not required.
Its urine-diverting separator keeps liquids and solids in separate removable containers, while top access allows both chambers to be reached without dismantling the toilet.
