Composting toilets are suitable for use in winter, provided they are made from appropriate materials and do not contain any mechanical parts that can freeze or be damaged by the cold. Our composting toilets TROBOLO WandaGO and WandaGO Lite are completely weather-proof, ensuring year-round usability, including in winter. You can confidently leave them outside during rainy, hailing, or snowy conditions without any concern. No parts are susceptible to weather damage, even in sub-zero temperatures.
