10 Best Porta Potti Toilets 2026 in the United States

The Camco TST MAX RV Toilet Treatment Drop-Ins are designed to keep porta-potti and RV toilets fresh and odor-free for up to a week with just one drop-in per 40-gallon tank. They use a special formula that not only controls unpleasant smells but also breaks down waste and toilet paper, helping to prevent clogs and improve the performance of waste sensors. This makes emptying your porta-potti easier and less messy. The lavender scent adds a pleasant touch without being overpowering.

These drop-ins are safe for septic systems and biodegradable, which means they are environmentally friendly and won’t harm your RV’s plumbing or a septic tank. Each pack includes 30 drop-ins, making it a good value for frequent campers or boaters. The product is lightweight and compact, so it won’t take up much space in your camping gear. While this treatment doesn’t affect the physical size, comfort, or seat height of porta-potties, it supports their maintenance by managing waste and odors effectively.

It’s important to remember this is a chemical treatment, not a toilet unit itself, so you’ll still need a suitable porta-potti to use it with. For those seeking an easy and reliable way to keep their portable toilet smelling fresh and functioning well during trips, this Camco treatment presents a solid choice.

The Kohree 5.8 Gal Camping Toilet is a practical and user-friendly solution for those needing a portable toilet. One of its standout features is the ergonomic diagonal design with an elongated bowl seat, which closely mimics the comfort of a home toilet. This design is particularly beneficial in spaces where room is limited. The toilet boasts a substantial waste tank capacity of 5.8 gallons, meaning you won't have to empty it frequently, and a fresh water capacity of 3.2 gallons, providing up to 120 flushes.

The built-in waste level indicator is a handy feature, ensuring you know when it's time for maintenance. Constructed from high-density polyethylene (HDPE) and polypropylene, the Kohree toilet is both durable and capable of supporting up to 440 pounds. Its dimensions, 14.6 inches in length, 16.5 inches in width, and 17.3 inches in height, make it suitable for users of all ages. The toilet’s T-type water outlet design ensures thorough cleaning, and the inclusion of a water gun helps maintain hygiene. It’s easy to empty thanks to the splash-free rotating spout.

This porta potty is versatile, perfect for a range of scenarios from camping trips to home use. However, it is worth noting that the product is non-returnable unless there is a quality issue, so careful consideration before purchase is advised. The toilet is relatively heavy at 16.61 pounds, which may be a consideration for some users. The Kohree 5.8 Gal Camping Toilet is a robust and convenient option, especially valued for its large capacity, ease of cleaning, and comfortable seat design.

The Kohree Camping Toilet offers a good balance of comfort and functionality for anyone needing a portable toilet for camping, RVs, boats, or trailers. Its elongated seat closely resembles a home toilet, providing comfort during use, which is a plus for longer trips or frequent use. The 5.3-gallon waste tank and 2.64-gallon water tank give you plenty of capacity to avoid constant emptying, with up to 90 flushes per fill. The flush system uses a high-pressure bellows pump and a T-type nozzle that help keep flushing easy and thorough, reducing mess and odors. The added water gun feature makes cleaning the toilet’s interior more convenient.

Made from durable high-density plastic, it supports users up to 440 pounds and stands compact at around 14.5 x 16.5 x 17 inches, making it fairly portable and easy to store. Weighing 13 pounds and featuring a handle, it’s simple to carry but not the lightest option available. One drawback is the lack of a clear waste level indicator, which means you have to check the tank manually to avoid surprises. Also, while the toilet is designed for easy assembly and disassembly, some users might find emptying the cassette a bit tricky until they get used to it.

This porta potty suits campers, RV travelers, and boaters who want a reliable, comfortable, and durable toilet without complicated installation. It is not ideal if you need very lightweight gear or a more compact footprint, but it covers the essentials well for most outdoor and mobile needs.
