The CM40 Next-Gen is the largest Clivus Multrum composting toilet, designed for high-use commercial facilities like public restrooms, parks, and campsites.
The EcoLet™ 240 25a is a fully self-contained, zero-leachate composting toilet—perfect for sites where no discharge is allowed. Designed for up to 3 people full-time or 4 part-time, it features a 240V automatic mixing system and internal heater for fast, odour-free composting. No plumbing, no drainage, and no fuss—just clean, efficient performance for serious off-grid living.
Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle, and larger waste volumes than the 1000 models. The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units.
The Sun-Mar Centrex system range is a split system, also known as an underfloor model. This means that the holding chamber is separate from the actual toilet pedestal itself. The major advantage of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below-floor space for installation, then this is the range for you.
