Thetford 224cw question. Can you tell me the dimensions of the toilet if I send you an image showing you where I would need to know the dimensions?

Hey Samuel!

The Thetford C224CW Cassette Toilet # TH29UE is 32-3/4" tall, between 16-3/4" and 17-7/8" wide (depending on whether the seat is facing forward or to the side) and 18-1/4" deep. This gravity-flush is more shallow compared to others in its category, but is one of the tallest due to the cassette housing in the bottom of the toilet. I'm also happy to take a look at your images if you'd like to send them my way. Just send a reply to the email you receive with the photo and I can confirm this will work for you!

Is your rig a van, a trailer, or a coach? What are the dimensions of your opening and your wall clearance?

In a seperate message I was able to attach a photo of where I need the measurements. I am renovating a 1985 skamper truck camper so I am trying to fit this into an existing cavity that does not have a toilet. I do not see a way to attach the photo here.

@SamuelK You'd have to email it, unfortunately. We don't have a way to add photos to comments (but I hear we're working on that). I think in most cases the # TH29UE will be a great fit, but since the 1985 Skamper is a pop up without an existing toilet, we could run into issues. Do you have the dimensions of the cavity?
