Campervan Toilet Selector
Pick the best van toilet for your space, budget and off-grid days. Clear verdict with pros/cons and emptying frequency.
Will a cassette toilet solve smell better than a porta potti?
Often yes, because **emptying is outside** via a hatch and many units seal better. You still need chemicals and regular dump points.
When does composting make sense?
When you do **long off-grid stretches**, have **full-height space** for a box and vent, want **no blue chemicals**, and accept the **liquids/solids routine**.
How much space should I plan?
- **Porta potti:** fits under a bench or in a small box. - **Cassette/composting:** prefer a **dedicated cabinet**; composting needs **vent route** and seat height clearance.
How often will I be emptying?
- **Porta/cassette:** typically **daily to every few days** with 2 people. - **Composting:** **liquids every 1–2 days**, **solids every 1–3 weeks** if managed well.
Can I start cheap and upgrade later?
Yes. Many begin with a **porta potti**, then move to **cassette or composting** once their travel pattern and tolerance are clear.
