How We Compared Portable Toilets to Determine the Best One for You

To find the best portable toilets for you, we scrutinized the top models on several key criteria:

  • Price: Price is the primary concern for many RV users. We considered toilets across a range of price points to suit different budgets, from wallet-friendly units under $150 to high-end models over $400.
  • Weight and Portability: Since you’ll likely need to empty and move your portable toilet often, we prioritized lightweight designs under 15 lbs for easier transport.
  • Durability: We looked for toilets built from robust, high-quality materials like ABS and polyethylene that can withstand the rigors of RV life and frequent use.
  • Comfort: When it comes to portable toilets, comfort should be the number one priority. Seat height, bowl size, and overall design were evaluated for user comfort and an at-home feel. We gave extra points to models with near-residential dimensions.
  • Ease of Use: A portable toilet must be easy to use. We considered factors like the flushing mechanism (manual vs. electric), tank level indicators, carrying handles, and cleaning simplicity when assessing user-friendliness. You can additionally look at the portable toilet reviews on retail websites to find out whether the toilet of your choice is easy to use.
  • Odor Control: Because no one wants a smelly RV, we favored toilets with effective odor management via sealed valves or, in the case of composting models, separation technology.
  • Tank Capacity: To minimize constant emptying, we compared waste and fresh water tank sizes, seeking a balance of generous capacity and manageable weight/bulk.
  • Special Features: Finally, we awarded bonus points for thoughtful extras like integrated toilet paper holders, vent buttons for splash-free emptying, hidden controls, and more.

Make Your RV Life Easier With Portable Toilets

Having a reliable portable toilet allows you to navigate the roads without any stress. When choosing a portable toilet for your rig, consider factors like price, capacity, ease of use, comfort, and odor control. Think about your typical trip length, the number of users, and how often you’re willing to empty the waste tank. And don’t forget to factor in your available storage space and power supply for battery-operated models.


No matter which portable toilets you choose, proper maintenance is key to avoiding unpleasant RV toilet mishaps. Empty and clean your toilet regularly, keep an eye on tank levels, and always use RV-safe chemicals. With a little care and the right gear, you can enjoy all the comforts of home—even when nature calls in nature.
