Composting Toilets

Sun-Mar composting toilets provide the convenience and sanitation of a flush toilet, in virtually any situation a flush toilet cannot be used. Their Centrex central composting models are designed to handle anything from a small weekend cabin to a regular family home. The Mobile unit is sealed against spills for use in RVs, and is USCG approved for marine use as well. The Spacesaver, Compact, and Excel self-contained units can be installed as quickly as finding a place to put them, and plugging them in (or installing a vent pipe for non-electric models).

Whether you need alternatives to a poor-performing septic system, are looking for something better than an outhouse, or just want to upgrade a boat that lacks an on-board toilet, Sun-Mar has the perfect solution. And not only do you get to enjoy the convenience of indoor plumbing, but all Sun-Mar toilet models produce fully useable compost at the end of their cycle. You can use it anywhere you would normally use compost, from your garden to your lawn.

We also carry a full range of Sun-Mar compost support products. From bulking material, to microbe/enzyme booster, to compost accelerator, you will find everything you need for your composting system here.
