Thetford 335 Porta Potti Portable Toilet, Piston Flush, 2.6 Gallon Capacity, Model 92828

The Thetford 335 Porta Potti is a self-contained portable toilet built for boats, RVs, and other spaces without a fixed marine head. It uses a piston pump flush system to deliver reliable, consistent flushing, averaging 27 flushes per fresh water fill. The unit holds 2.6 gallons of fresh water for flushing and 2.6 gallons of waste capacity, making it well suited for weekend trips or extended time aboard.

The 335 features a refreshed, modern design with an exclusive rotating pour-out spout that makes emptying the waste tank simple and mess-free, along with an ergonomic carrying handle for easy transport between the boat and a dump station. A standard lid latch keeps the cover secure during transit and rough water. The toilet is molded from high density polyethylene (HDPE) and polypropylene (PP), materials chosen for their durability, resistance to scratching, and ease of cleaning. Thetford backs the 335 Porta Potti with a 3 year manufacturer's warranty.

This is a self-contained, portable unit -- it is not a fitment-specific replacement part, so it works anywhere a compact holding-tank toilet is needed rather than being tied to a particular boat make or model.
