Features to know about

Comfort and Privacy Wherever You Camp

If you've ever tried squeezing into a cramped bathroom or making a late-night dash outside, you know how awkward that can be. This bench-style cassette toilet was made for van and RV wet baths, giving you a sturdy, full-height seat that feels just like home. The built-in water tank makes flushing easy. Just press a button for a thorough rinse, with no complicated plumbing or hookups required. And the top-mounted lever lets you open or close the blade valve easily - just slide the lever to use the toilet, then close it up to seal away odors.

Tidy Waste Disposal, with No Surprises

Forgetting to empty the tank is a thing of the past. An indicator lets you know exactly when the cassette is full, so you never have to guess. When it's time to dump, just open the hatch, slide out the rolling cassette, and take it to any dump station or restroom. With the built-in handle, wheels, and pour spout, cleanup is quick and manageable, wherever you empty the tank.

Initially bought the right toilet, but the wrong side access, got a replacement and installed it. Installation was easy. If you are switching from the old style toilet to the new one and have a pre-existing access point for the cassette, the height of the toilet may need to be adjusted.

I appreciate that feedback, but I am glad it all worked out for you and you were able to get it installed. It looks great! What kind of trailer did you end up installing this in?

This review is about the purchase process, not the product since it just arrived.
Ordering, easy and efficient. Shipping fee, great it was included. Shipping time, very fast. Condition upon arrival, very good. But, if anyone had treated the box roughly, there would have been damage. Very little protection from Thetford.
