The number #1 selling composting toilet in North America
The Sun-Mar Excel is the best selling unit for good reasons. Its a high capacity Bio-drum toilet that is very simple to operate, features well proven technology and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). It is the composting toilet that has set the standard for the whole industry.
The Excel has enough capacity that it can be used just about anywhere; in residences, cottages and even in light commercial applications from three adults or families of 5 continuous use or 6 adults or families of 8 for seasonal/vacation use.
Easily retrofitted into your home because it contains everything you need. The Sun-Mar Excel composting toilet sits directly on your restroom floor, so installation simply involves cutting a hole in the roof for the vent, gluing a few pieces of pipe together, connecting the emergency overflow hose to a small drywell or holding tank, and then plugging the unit into an electrical outlet.
Finally, retrieving finished compost is easy with the included compost finishing drawer located at the bottom of the unit; just remove drawer and use as desired. Excel kits include: starter bed material, compost accelerant, vent pipe, couplers, 45 and 90 degree bend fittings, draft improving vent cap diffuser fitting, and roof flashing.
Completely easy to set up in a few hours without paying for a plumber or electrician. This well designed composting toilet does not smell at all, saves lots of water and creates valuable compost for your garden. Use it just one time and it will change your thinking about composting.
