Thetford Toilets - Portable

Thetford Porta Potti®: The Gold Standard in Portable Toilets

When it comes to portable sanitation, few names carry more authority than Thetford. Thetford is widely recognized as the inventor of the original Porta Potti®, and decades of refinement have made the brand synonymous with reliable, odor-free, and genuinely user-friendly portable toilets. Whether you're outfitting a camper van, keeping a boat compliant, heading into the backcountry, or simply managing a home renovation without full plumbing, Thetford's lineup covers the full spectrum of portable sanitation needs.

How Thetford Portable Toilets Work

A Thetford Porta Potti consists of two parts: a top tank holding fresh water for flushing and a bottom tank into which waste water is washed for storage and dilution. The great advantage of these mobile toilets is that they don't need to be connected to a sewer, water line, or drain — and there's no need to empty them every day — making them easy to move around and store. This self-contained design is what makes the Porta Potti such a versatile solution across so many activities and environments.

Porta Potti® Model Range

Thetford offers multiple model tiers to match different use cases, tank capacities, and comfort preferences.

• Entry-level models (100 & 300 series): The Porta Potti 100 series is a simple and practical, medium-sized camping toilet that is lightweight and comfortable to use. These are ideal for weekend trips and minimalist adventurers who want function without complexity.
• Mid-range models (335/345): These versatile portable toilets feature a piston pump flush and a 3.2-gallon removable waste water tank, making them ideal for camping, outdoor events, boating, and toddler training.
• Full-featured models (365/565): The larger models offer a piston pump flush with a 5.5-gallon removable waste water tank , providing extended capacity between emptyings — a major plus for longer trips.
• Premium 565E with electric flush: User-friendly and easy to set up anywhere, the 565E provides a familiar bathroom experience in remote locations thanks to its large bowl, comfortable seat height, and battery-powered electric flush.
• Porta Potti Curve (565 series): The Porta Potti 565 distinguishes itself with a unique design, improved seating height, and premium features including a toilet roll holder, integrated control panel, and level indicators for both the waste-holding tank and flush-water tank.

Built for Boats, RVs, and Beyond

Whether you're a day tripper or a week-long cruiser, Thetford's marine portables are compact, convenient, and designed with marine-specific features and benefits. Floor-mounting plates are available for models like the 565 series, securing the portable toilet to the floor during travel to prevent shifting and damage — critical for rough-water or off-road conditions. Sanitary, odorless, and leak-proof, the Porta Potti remains the world's leading brand of portable toilet.

Accessories That Complete the System

Thetford's portable toilet ecosystem extends well beyond the unit itself. Thoughtful built-in features like an exclusive rotating pour-out spout for no-splash emptying, a sealed slide valve to contain odors, and a built-in deodorant storage compartment round out the experience. Carry bags made from durable polyester zip up for transport, resist shrinking and discoloration, and include an easy-clean glazed lining with attached handles and a collapsible design for easy storage. Thetford's own Aqua Kem and Aqua Rinse chemical treatments are designed specifically to maintain these units between uses.

With 58 products spanning models, accessories, and holding-tank care, Thetford's portable toilet catalog gives you everything needed to stay comfortable — no matter how far off the beaten path you go.
