Garage potty


Needed for use when I work in the yard.. garage is a perfect place. near the mop sink.

Didnt last long


Purchased March 2014. Used seldom. April 2015, found tube from pump in fresh water tank to bowl broke at the pump. Hose connection at bowl delivery spout is not accessible. So no way to replace the hose. Company not willing to warrenty 3 weeks after warrenty period. I have no idea when the hose actually broke but it would have been after camping season in 2014. Hose is very frail and continued to split when I attempted to reconnect it to the pump. The Curve was in a garage the entire time when not in camping use. Explained all this to Thetford. Was told I would just need to buy another porta potty. Company had no part number for the hose so I would need to buy a pump. It comes with a hose. Pump cost more than new potty. Imagine the weakest link of a product not accessible to replace? I call it a Disposable Depository.

Perfect product for our needs.


We have an RV but since our son grew up and moved out on his own, my husband and I find camping in our conversion van to be far easier and convenient. BUT... I still want amenities such as A/C (which we installed) and my own toilet. This Thetford Curve is PERFECT for the curtained space we use as our "powder room" and is large enough for even a guy to use. Terrific product. We really can camp anywhere now!
