PROS

  • Versatile with uses in a variety of situations, but particularly great for the outdoors.
  • Highly portable, but great for being permanently placed also.
  • Modern design, comfortable and purpose built for adults.
  • Excellent sized tanks meaning refilling and emptying is not constantly required.
  • It's fully sealed so you are never going to have to worry about splashback or odors.
  • Piston flush which is both quiet and powerful.
  • Robust unit.

CONS

  • Depending on how high you want to be, this unit is about two inches shorter in height and length than the Thetford 550E.
  • Priced just under the Thetford 550E, this unit is priced a little on the high side.

VERDICT

This is an excellent toilet that operates very similarly to the Thetford 550E Curve, but with a few less whizz bang features.  However, it is still a step above many others with a piston flush and excellent sizing to make all adults comfortable using this portable toilet.  It's highly portable and easy to use, making it an ideal unit for many different situations.

Tips

  • Help to keep the toilet clean by putting some water or a small bit of toilet paper in the bottom before using it for solid waste.
  • Keep the lid of the toilet closed until you have moved the lever to open the access to the waste tank before use.
  • Keep some wet wipes close by to encourage others to clean the toilet after use if necessary.  Don’t flush these down the toilet.
  • Using the appropriate cleaning chemicals not only helps to keep the camping toilet clean but also assists with keeping the parts lubricated correctly.
  • It’s a good idea when handling portable toilet waste tanks to have some disposable gloves with you.

Cleaning and care

As the warranty does not cover damage you might do to the portable toilet, it is recommended to use the Thetford cleaning products.  Never use rough cleaners, pastes, scourers or acids on any of the toilet or toilet parts, especially the valves and seals.  Using the recommended products also helps to keep all parts properly maintained.
