Thetford Porta Potti 335
The Thetford Porta Potti is the basis for durable portable toilets. If you are looking for a comfortable, practical and durable portable toilet that doesn’t require a connection to a drainage or water system, Thetford has the perfect solution for you: the Porta Potti.
The toilet has an integrated lid lock, a recess for opening the lid, an improved push handle and a more comfortable handle for the waste holding tank. The stopper on the waste-holding tank holds the emptying nozzle in place and makes reinserting the two tanks even easier. Integrated cover lock for easy transportation, with recess for opening.
The smooth lines and subtle curves are not just important to the appearance of the toilets, but also provide optimum comfort and ease of use. Improved blade opener. New more comfortable handle on the waste holding tank.
