RV owners and campers, this Thetford carrying bag is an absolute essential if you own a portable toilet! The large size (17.7x17.7x17.7 inches) fits perfectly around Porta Potti 365 and 565E models, providing crucial protection during transport and storage. The strong polyester construction feels durable enough to handle rough treatment in your RV storage or car trunk, and the quality zipper opens and closes smoothly without catching. What's brilliant is how it eliminates the need to keep the original cardboard box - you just slip the toilet into this bag, zip it up, and it's protected from scratches, dust, and moisture. The two handles make carrying surprisingly comfortable, even with the toilet inside. I've used mine for years of camping trips and RV travel, and it's held up beautifully - no tears, fading, or broken zippers despite rough handling. The machine washable feature is genius too - when it inevitably gets dirty from outdoor use, you just toss it in the wash and it comes out looking new. If you're tired of your portable toilet getting scuffed up during travel or taking up space with that bulky original packaging, this carrying bag is one of those simple solutions that just makes life easier. Well worth the investment for protecting your expensive portable toilet!
