Sun-Mar Composting Toilets

Sun-Mar Composting Toilets

We carry the complete product line of Sun-Mar Composting Toilets. Sun-Mar is the world leader in cottage toilets, and manufactures 19 models from 5 different product families.

Each model is distinguished by innovative design, superior technology, and Sun-Mar's legendary quality. The high quality materials used in a Sun-Mar are largely fiberglass and marine grade stainless steel.  Each carries an amazing 25 year warranty on the body.

The unique three chamber system and the patented Bio-drum designed into all Sun-Mar units, are just two examples of Sun-Mar's original and effective approach to composting. The way a Sun-Mar works may be unique, but it is also elegantly simple. No one else in the world puts a composting drum inside a toilet. And, of course, as with all composting toilets that are used properly, there is no odor and no mess.

All units except "Mobile" are available in white or bone colors.
