Sun-Mar CENTREX 1000 Remote Composting Toilet System — Electric, Regular Capacity, Ultra-Low Flush

Product Description

The Sun-Mar CENTREX 1000 takes a fundamentally different approach to composting toilets — and for many installations, it's the right one. Unlike Sun-Mar's self-contained models where the composting chamber lives beneath the toilet seat, the CENTREX 1000 is a remote composting system: the composter unit installs away from the toilet, in a basement, crawl space, or adjacent room, while a standard-looking ultra-low flush toilet sits in the bathroom above. The result is a comfortable, familiar bathroom experience paired with a completely waterless, sewer-free waste management system. The CENTREX 1000 is the regular-capacity electric model in the Centrex line, designed for light seasonal use at cabins, cottages, camps, and similar properties where electricity is available and the bathroom and composter can be separated by a floor or wall.

• Remote Composter Design — The composting unit installs in a separate space away from the toilet — a basement, mechanical room, or crawlspace — keeping the bathroom clean and conventional in appearance.
• For Use with 1-Pint Flush Toilets — The CENTREX 1000 is designed for use with ultra-low water flush toilets (1 pint per flush), purchased separately. This preserves the familiar feel of a standard toilet while keeping water use minimal and the composting process functional.
• Built-In Heating Element and Fan — A thermostat-controlled 260W heater assists with liquid evaporation, and a 35W fan ensures odorless operation by maintaining continuous airflow through the composting chamber.
• 1" Drain Hose Included and Required — All 1000 series units are supplied with a 1" drain hose, which must be connected in all applications.
• Light Seasonal Capacity — Rated for up to 5 adults or families of 7 for seasonal and vacation use.
• Versatile Installation — Suitable for cabins, cottages, homes, businesses, resorts, camps, treehouses, and workshops — anywhere the composter can be located away from the toilet.
• 3-Year Parts Warranty — All Sun-Mar composting toilets are backed by a 3-year warranty on parts.

FAQs

Q: What makes the CENTREX 1000 different from Sun-Mar's self-contained models? A: The CENTREX 1000 is a remote composting system — the composter unit installs away from the toilet in a separate space such as a basement or crawl space. Sun-Mar's self-contained models (Excel, Compact, SpaceSaver) house the composting chamber directly beneath the seat in a single unit. The Centrex approach gives the bathroom a conventional appearance while keeping composting infrastructure out of sight.

Q: Does the CENTREX 1000 come with a toilet? A: No. The CENTREX 1000 is the composter unit only. It is designed for use with 1-pint flush toilets, which are purchased separately.

Q: Is the 1" drain hose connection required? A: Yes. All 1000 series composting toilets are supplied with a 1" drain hose, and it must be connected in all applications.

Q: What is the capacity of the CENTREX 1000? A: The CENTREX 1000 is rated for seasonal and vacation use, accommodating up to 5 adults or families of 7 per day. It is described as a regular-capacity model ideal for light seasonal usage.

Q: Does the CENTREX 1000 require electricity? A: Yes. Electricity must be connected while the unit is in use. The thermostat-controlled heater draws up to 260W when active, and the fan draws 35W continuously, for an average draw of approximately 150W.

Q: What is the warranty on the CENTREX 1000? A: All Sun-Mar composting toilets carry a 3-year warranty on parts.
