!!! Twusch Toilet Liner Contest Is Closed !!!

Our winner was Joe Ortiz.

You can find out all about it in our post.

Thank you to everyone who entered, and you can still get your liner directly from Twusch!



A few weeks back, I shared some of the cool products we found at Caravan Salon in Germany on our trip. One of them was a ceramic toilet bowl liner for cassette toilets called “Twusch“, and I wanted one. With a little digging, I was able to find them for sale up in Canada.  I ordered one (we paid full retail), and we install it and put it to the test in this video.


Swapping out a plastic toilet for a china one is a very common RV upgrade.  We even did it with our very first RV, Das Bus!  And once you’ve done it, it’s easy to see why.  Porcelain or china toilets are less prone to odors, and they rinse clean easier and with much less water than their plastic counterparts.  Unfortunately, the china toilet upgrade hasn’t been available to cassette toilet owners.  Casette toilets have all been plastic… Until now.

The Twusch is a thin porcelain liner, that’s shaped to exactly fit the contours of a Thetford cassette toilet.  There are several models of toilets, and each has a slightly different shape, so you’ll need to know the model of your toilet to make sure you get the correct liner.  For us in our Winnebago EKKO, that was a Thetford 220 series.  The shipping from Canada didn’t take long at all – we had it inside of a week.

The install, which you’ll see in the video, couldn’t be simpler.

  1. Clean toilet and outside of Twusch
  2. Drop in Twusch liner
  3. Silicone around the top gap to seal it up

That’s pretty much it.  We used it (like, seriously used it) for a week long trip and it lived up to the promise.  It really did leave us with a less smelly bowl, and we really did use less water when flushing. It only added about a pound of weight to our RV, so I really don’t see any negatives.

This is an easy mod that pretty much anyone could handle, so go for it!  You’ll be glad you did.
