Trelino Evo L Composting Toilet review
The household-sized version — same system, capacities that suit daily family use.
By Tom Rowland · Updated 20 July 2026 · Price checked against our tracker
Identical philosophy to the Evo M — urine separation, no water, no chemicals — in the size that makes it a genuine full-time or family option rather than an occasional backup: bigger solids container, bigger canister, domestic seat height. If a composting toilet would be your household's actual plan (off-grid annexe, boat, smallholding, or resilience against a long water outage), size matters more than price here; emptying less often is the entire quality-of-life difference.
