Whether you need a backup toilet for your RV, a reliable head for your boat, or a sanitation solution for remote camping, the Dometic 976 portable toilet delivers genuine comfort and odor control in a compact, easy-to-clean package. The detachable waste tank and sealed slide valve keep things hygienic from the campsite all the way to the dump station.
The Dometic 976 is part of Dometic's well-established portable toilet lineup, sitting between the compact 970 and the larger 991 in terms of tank capacity and seat height. This model (part number 301097606) is finished in gray and features a rotating pour spout on the waste tank for controlled, splash-free emptying at any standard RV dump station or restroom toilet.
The upper tank holds fresh water for flushing and connects directly to the piston-action flush pump. A few strokes pre-charges the bowl with water before use, and a full flush rinses cleanly. The lower waste tank detaches with a simple twist-and-lock mechanism -- no tools, no mess. Once detached, the integrated pour spout and sealed slide valve let you empty and rinse the tank without exposing yourself to waste.
Manual piston pump delivers a controlled flush without any electrical hookup. Works off-grid, on the water, or anywhere in between.
Leak-proof slide valve separates the upper and lower tanks, blocking odors and preventing spills during transport and storage.
5.3-gallon lower tank twists off quickly for easy carrying to a dump station. Rotating pour spout allows precise, controlled emptying.
At 15.5" x 15.5" x 13.5", the 976 fits in RV wet baths, boat heads, truck campers, and under-bench storage with minimal footprint.
Dometic produces several portable toilet families. The 970 series is the entry-level compact unit with a smaller waste tank suited for solo use or short trips. The 976 steps up with a 5.3-gallon waste capacity and taller seat height, making it more comfortable for extended use by adults. The 991 series adds even greater capacity for larger groups or longer excursions.
The 976 is the most popular choice among weekend campers, boat owners, and RVers who need a secondary or emergency toilet. It is also commonly used as the primary toilet in tent trailers, pop-up campers, cargo van conversions, and small truck campers where a built-in cassette or china toilet would require plumbing modifications.
The 976 is completely self-contained. There are no electrical connections, no water supply lines to tap, and no black tank to manage. Add Dometic or Thetford portable toilet chemical to the waste tank, fill the upper freshwater tank, and it is ready to use anywhere.
To control odor and break down waste, use a dedicated portable toilet chemical in the lower tank before use. Dometic and Thetford both make liquid and drop-in tablet treatments formulated for portable units. Do not use standard RV black tank treatments designed for large holding tanks -- the concentration and formula differ. A small amount of rinse solution in the upper tank also helps keep the bowl clean between flushes.
The upper flush tank is filled via a standard fill cap on the top of the unit. Use clean water only -- do not add tank treatments or chemicals to the upper tank. Treatments belong in the lower waste tank only.
To empty the 976, close the slide valve on the lower tank, then rotate the tank counterclockwise to detach it from the upper assembly. Carry the lower tank to a dump station or restroom. Extend the rotating pour spout, open the vent cap on the opposite side to allow air flow, and empty the tank. Rinse thoroughly with clean water before reattaching. A small amount of waste holding chemical in the empty tank before storage prevents residual odors.
The unit ships at 14.01 lbs empty. A full 5.3-gallon waste tank adds approximately 44 lbs (water weight alone). Factor this into carrying and storage plans, especially on boats or in slide-out compartments with weight limits.
