Product Information
Full details
The Thetford Twusch Porcelain Insert is designed for caravan and motorhome owners using a C220 series cassette toilet who want to upgrade from plastic to a premium, porcelain experience. It provides a more hygienic, odor-resistant, and easier-to-clean surface without adding significant weight to the vehicle. However, potential users should note that the installation requires the use of sanitary silicone, making it a permanent structural upgrade that necessitates careful application for a proper seal.

FAQs
Does this replace the entire toilet?
No, this is an insert that sits within your existing Thetford C220 plastic bowl.
Is the installation reversible?
No, because the insert is bonded to the original bowl with sanitary silicone, it is considered a permanent installation.
Will this fit a C200 or C250 series toilet?
No, the Twusch insert is precision-molded specifically for the C220 series.
Does it crack easily?
The high-fired porcelain is durable for vehicle use, but it should be protected from heavy impacts just like a household porcelain toilet.
How do I clean the insert?
Use standard, non-abrasive toilet cleaners and a soft cloth to protect the nano-sealed finish.
Will this affect my vehicle's weight limit?
At only 800g, the impact on your vehicle's total weight is negligible.
Troubleshooting
Water leaking between the insert and the bowl base.
Check that the sanitary silicone was applied in a continuous, uninterrupted bead during the initial installation.
Difficulty flushing efficiently.
Ensure the bowl is seated correctly and that no silicone residue is obstructing the flush rim water ports.

Setup, Compatibility & Care
To install, ensure the toilet bowl is thoroughly cleaned and dried before application. Apply a high-quality sanitary-grade silicone sealant to the contact points as directed by the instructions, ensuring a water-tight seal between the insert and the existing bowl. The Twusch is exclusively compatible with the Thetford C220 series; attempting installation on other models will result in fitment failure. For care, avoid using harsh abrasive scouring pads that could compromise the nano-seal. Use a soft cloth or a specialized non-abrasive toilet cleaner to maintain the finish.
