Thetford Porta Potti 345 Portable Camping / Camper Van Toilet

The Thetford Porta Potti 345 is a compact, comfortable and easy-to-use portable toilet, ideal for camper vans, motorhomes, caravans, camping, boats and other situations where a permanent toilet installation is not available.

Part of Thetford’s popular Porta Potti 300 Series, the 345 combines a practical manual piston flush, a generous fresh-water tank and a useful waste-tank level indicator in a compact medium-sized design. It requires no permanent plumbing, drainage or electrical connection, making it a simple and reliable choice for leisure vehicles and off-grid use.

Compact, Practical Design

The Porta Potti 345 measures just 330 x 383 x 427mm, making it a great option for camper vans and conversions where storage space is limited.

With a 324mm seat height, it keeps the overall dimensions compact while still providing a comfortable and practical toilet solution for travelling and camping.

Reliable Manual Piston Flush

The Porta Potti 345 uses Thetford’s proven manual piston pump flushing system.

The flush is operated entirely by hand, so there are no batteries, wiring or electrical connections required. This makes the 345 particularly well suited to camper vans, caravans and off-grid setups where simplicity and reliability are important.

12 Litre Waste Holding Tank

The lower section of the Porta Potti 345 incorporates a 12 litre waste-holding tank, providing useful capacity while helping to keep the toilet compact and manageable.

When it needs emptying, the waste tank separates from the upper section and features a rotating pour-out spout, helping make disposal cleaner and easier.

15 Litre Fresh Water Tank

The upper section contains a generous 15 litre fresh-water flushing tank, allowing the toilet to operate completely independently from your camper van or caravan’s main water system.

Simply fill the flush tank before travelling and the Porta Potti 345 is ready to use.

Waste Tank Level Indicator

One of the key advantages of the Porta Potti 345 over more basic models is its waste-holding tank level indicator.

This provides a quick visual indication of when the tank is approaching capacity, helping you avoid unnecessary checks and making it easier to know when the toilet needs emptying.

Easy to Transport and Store

At approximately 3.8kg empty, the Porta Potti 345 is lightweight enough to move and store easily.

Its relatively low overall height also makes it a strong choice for camper van conversions where the toilet may need to fit beneath a seat, inside a cupboard or within a dedicated storage compartment.

Completely Self-Contained

The Porta Potti consists of two main sections: an upper section containing the toilet bowl and flush-water tank, and a detachable lower waste-holding tank.

There is no requirement for mains water, waste plumbing or electricity, giving you the flexibility to use the toilet wherever it is needed.

Ideal for Camper Vans, Caravans and Camping
