Upgrade Your Cassette Toilet — Shop the Twusch + SOG Dream Team

Upgrade Your RV Toilet with a Twusch Porcelain Insert

Your RV bathroom should feel clean and comfortable—not like a compromise. Unfortunately, plastic RV toilet bowls can become scratched, stained and harder to keep looking fresh over time.

The Twusch porcelain insert fits directly inside your existing Thetford cassette toilet, giving you the smooth, household-style feel of porcelain without replacing the entire toilet.

A Cleaner, More Comfortable RV Bathroom

The nano-sealed porcelain surface is smooth, durable and easier to clean than worn plastic. Waste and residue are less likely to stick, so the bowl rinses clean more easily and may require less water—especially helpful when you’re camping with a limited fresh-water supply.

Why RV Owners Choose Twusch

  • Easy to clean: The smooth porcelain surface helps prevent residue and stains from clinging to the bowl.

  • Scratch- and stain-resistant: Porcelain keeps its clean appearance longer than a worn plastic toilet bowl.

  • Lightweight: Twusch weighs less than 800 grams, making it ideal for RVs, campers and caravans.

  • DIY-friendly installation: Upgrade your existing toilet without plumbing modifications or a complete toilet replacement.

  • Made in Germany: Designed specifically for compatible Thetford cassette toilets.

Twusch is a simple RV toilet upgrade that makes your bathroom feel cleaner, more comfortable and a little more like home.

Choose your toilet model and find the Twusch made to fit your RV.
