Excelet CS – 2 comes with a dual action chamber screen. This composting toilet model is suitable for use by one person full-time, installed in the bathroom of a slab floor house or outside enclosure (e.g. shed). Alternatively, the toilet would suit up to 2-3 people as second or part-time use toilet (e.g. weekender). The Excelet is Nature Loo’s premium model of the self-contained Excelet Range and is certified to Australian & New Zealand Standard 1546.2 as the Excelet-4 (i.e. with 4 chambers). Therefore, if approval becomes a concern two additional chambers can be purchased at a later date. The Excelet chamber screen blocks any view of the contents of the chamber (required for state approval).
