One of the most popular Sun-Mar™ models to date, this high capacity bio-drum toilet is both simple to operate and reliable. As the first composting toilet model to be quality and performance certified in North America, this toilet has set the standard for the myriad of composting toilets that have followed.

With a high capacity suitable for residential use, holiday houses and in some circumstances, light commercial use, The Excel is odourless and produces clean, safe compost.

The Excel comes with a hidden vent installed at the back of the unit. This draws any odours away from the toilet itself. While the system is capable of processing all liquids through evaporation, there is an emergency drain fitted at the back of the toilet. This will need to be connected in instances of high use or in the case of power outages.
