The Thetford Porta Potti portable toilet range

If you are looking for a comfortable, practical and durable portable toilet that doesnt have to be connected to a drainage or water system, Thetford have the perfect solution for you: The Porta Potti.

Advantages of the Porta Potti:

  • Lightweight, high quality plastic
  • Durable and practical in use
  • Integrated emptying spout
  • Handy vent button for splash free emptying
  • Choice of flushing system
  • Level indicator, to show when it needs emptying (not on models 145, 165)
  • A three-year warranty
  • Extensive range of Thetford Toilet Care products
  • Good quality achieved through years of experience in portable sanitation.


Because the toilet is compact, lightweight and easy to use, the Porta Potti is often used in caravans, motor homes, boats, folding trailers and even summer houses. But these portable toilets also come in handy during house renovations or just as a second toilet. The Porta Potti is simple to transport and really can be placed anywhere.


Thetford pay a lot of attention to quality, thereby ensuring that your Thetford Porta Potti will give you many years of trouble-free service. Porta Pottis are made of durable high-grade plastic, which, combined with their rounded shape, means they are easy to clean and maintain. And these portable toilets have many innovative features that optimise comfort and ease of use, such as an integrated emptying spout, a luxury electric flusing system and a level indicator for the waste-holding tank.


The Porta Potti consists of two sections. The upper section is a combined flush-water tank and toilet bowl with detachable seat and cover. The lower section is the waste-holding tank.

  1. The two parts are easy to detach using a handle at the rear of the toilet.
  2. Adding the correct dosage of Thetford Toilet Care products to the waste-holding tank using the emptying spout is simple.
  3. Water and flush-water fluid can be poured directly into the top of the flush-water tank.
  4. The lightweight waste-holding tank is easy to transport and features a handy container to store the two free samples of our toilet care products
  5. All models feature a unique integrated rotating emptying spout, making emptying as simple as can be. There is no need to dismantle or clean seperate parts. The waste-holding tank also has a vent button, which you press while emptying to prevent unpleasant splashing.
  6. The Porta Pottis are equipped with a level indicator (except Porta Potti 145 & 165) so you are warned in good time when the waste-holding tank needs emptying.

Thetford Portable Toilets FAQ - your questions answered...

What is a Thetford portable toilet?
Thetford Porta Pottis are two-piece, fresh-water flush toilets that conveniently travel anywhere a toilet is needed. They are easy-to-carry, completely self-contained, sanitary, odorless, leak proof, and hold their own fresh water supply for flushing.

Where can Porta Pottis be used?
The simple answer: wherever one is needed. In fact, portable toilets have a multitude of uses - probably many more than you may have imagined. Of course, they're commonly used for leisure-related activities: in vans and van conversions; boats; camp sites; in cabins and cottages; on hunting trips; and with RV's (smaller models, pop-ups, or as a second toilet for larger RV's). But they're also ideal for: toilet training children; construction sites; bedside; over-the-road, long-haul trucks; emergency situations; and locations where there is a shortage of water and/or power.

How does a Porta Potti work?
Actually, a Porta Potti is quite simple to use. Its top section includes the seat, cover, bowl, flushing bellows and fresh water tank. The bottom section is an odor and gas-tight detachable waste holding tank. The two sections are held together by a locking latch, enabling the entire unit to be hand-carried as one piece or each section to be carried separately.Thus, the Porta Potti goes wherever a toilet is needed. And, since it carries its own fresh water for flushing, you needn't worry about using it where water is scarce. Depending on the model, a Porta Potti will average between 27-62 fresh-water flushes between emptyings. When the lower tank is full, simply separate the sections, take the bottom section to any conventional toilet and empty it there

There are many models... how do I decide?
Most importantly, determine the right size for you. Size, the primary difference between Porta Potti models, is measured two ways:

  • Height - Generally, the taller the unit, the more convenient it is to use. (If you have a specific area/application for your Porta Potti, you'll want to measure to determine which size is right. There are, for example, some "tight-quarters" applications, such as v-berth marine craft, where smaller is better.)
  • Tank capacity - The larger the capacity, the greater the time between emptying - saving time and effort

How do I repair my Porta Potti's flushing bellows?
Before removing the old part, be sure to purchase the replacement bellows that's right for your Porta Potti model. Comprehensive instructions for removal of the old part and installation of the new part come with the new bellows.

What should I use to clean my Porta Potti?
We recommend you use Thetford's Aqua-Clean®, a high-grade, non-abrasive cleaner, and a soft sponge or cloth. Do not use a highly-concentrated or high-acid content household cleaner, nor those containing abrasives, such as a scouring powder. They'll scratch the surface of your Porta Potti, diminishing its looks, and also could hamper its performance by damaging the valve seal or plastic parts.
