Dometic SeaLand 965 MSD Portable Toilet, 5 Gallon Capacity, Parchment - Part 311196502

The Dometic SeaLand 965 MSD Portable Toilet (part number 311196502) is a self-contained, adult-sized toilet built for boaters who need reliable sanitation without a fixed marine head. It holds 5 gallons (19 L) of waste, enough for an estimated 30 to 50 uses before the holding tank needs to be emptied, making it a practical choice for extended trips. A separate, self-contained 2.6 gallon (9.8 L) freshwater supply feeds a bellows-style flush that delivers a bowl-cleaning rinse with every use, and the tank refills easily through a top-mounted fill port without removing the unit.

The toilet is molded from high-density polyethylene for strength and impact resistance, so it can be dropped or stood on without cracking. It is finished in a parchment color with a matte, scratch-resistant surface that stays looking new and wipes clean easily. Secure locking side latches join the upper seat unit to the lower holding tank for a firm, safety-rated seal during use and transport, and stainless steel hold-down brackets are included to anchor the unit to the deck or floor. The adult-size seat and lid are designed for comfort as well as safety.

Because it is fully portable and self-contained, the 965 MSD works well aboard boats and also serves RVs, trailers, vans, trucks, camping setups, cottages, work sites, and bedside use. All parts and seals are user replaceable, and the unit is simple to winterize and maintain between seasons.
