Dometic SeaLand 964 Portable Toilet, 2.5 Gallon Holding Tank, Parchment

The Dometic SeaLand 964 Portable Toilet is a self-contained, adult-sized MSD toilet built for boaters, RVers, and campers who need reliable sanitation without a fixed plumbing hookup. Its 2.5 gallon (9.5 L) holding tank provides enough capacity for roughly 30 to 50 uses before it needs emptying, while a separate 2.6 gallon (9.8 L) freshwater supply feeds the bellows-style flush, which delivers a bowl-cleaning rinse with every use. The freshwater tank fills easily through a top-mounted port without removing the unit from its mounting location.

Construction is high-density polyethylene, chosen for its strength and toughness so the toilet can be dropped or stood on without cracking. The exterior is finished in a parchment color with a scratch-resistant matte finish that stays looking new over years of use. The adult-size seat and lid provide comfortable seating, and side latches lock firmly to secure the unit during travel or rough water. Stainless steel hold-down brackets are included so the toilet can be mounted securely to a floor surface, and all internal parts and seals are user replaceable, making winterizing and routine maintenance straightforward.

This portable toilet suits boats, RVs, trailers, vans, campers, cottages, trucks, work sites, and other settings where a compact, self-contained sanitation solution is needed.
