Thetford Porta Potti 335 Marine Toilet w/Hold Down Kit

The Thetford Porta Potti 335 Marine Toilet with Hold Down Kit is a compact, purpose-built portable sanitation system designed for boats of all sizes. This manual-flush toilet combines proven reliability with practical installation features that secure it permanently to your vessel's deck or cabin floor, eliminating the movement and noise that plague cheaper portable alternatives.

The Porta Potti 335 operates via a manual piston pump flush mechanism, providing consistent water pressure without relying on pressurized freshwater systems. Its integrated pour-out spout allows controlled waste disposal without disassembly, reducing mess during pump-out operations at marina facilities. The white finish withstands marine UV exposure and reflects heat in tight cabin spaces. At 9.2 pounds with footprint dimensions of 14 x 13 inches, the 335 fits snugly in compact head compartments while the included hold-down kit bolts securely through deck penetrations, eliminating the flex and vibration that occurs with adhesive-mounted units in rough seas.

Weekend fishermen and serious offshore anglers both value the Porta Potti 335 for extended trips beyond marina facilities. Charter boats and fishing guides rely on its durability and the hold-down kit's secure mounting to prevent tipping or movement during rough conditions. The Thetford brand has established a strong reputation in marine sanitation across recreational and commercial vessels, and the 335 model delivers that same proven engineering in a size-efficient package that doesn't compromise functionality for space savings.
