Product Information
Full details
The Thetford Twusch Porcelain Insert is designed for caravan, motorhome, and campervan owners seeking to upgrade their standard plastic C500 toilet bowl to a more hygienic and durable porcelain surface. By providing a non-porous, nano-sealed finish, the insert significantly eases cleaning and reduces odor retention without adding substantial weight to your vehicle; however, it requires a careful, permanent installation using sanitary silicone which prevents it from being removed once set.

FAQs
Does the Twusch increase the weight of my caravan significantly?
No, the insert weighs approximately 800g, which is negligible for most vehicle payloads.
Can I remove the insert if I want to sell my caravan?
The Twusch is designed for a permanent installation using silicone, so it is generally not intended for removal.
What type of toilet cleaner should I use?
Use a non-abrasive, bathroom-safe cleaner and a soft cloth to avoid scratching the nano-sealed finish.
Is this compatible with all Thetford toilets?
No, it is precision-engineered specifically for the Thetford C500 cassette toilet.
How long must I wait before using the toilet after installation?
Follow the curing time instructions on your specific sanitary silicone product, usually between 24 and 48 hours.
Troubleshooting
Silicone seal appears to have gaps
Ensure the original bowl was completely dry and clean before application; re-apply a small bead of sanitary silicone to seal the gap.
Water pooling on the edge of the insert
Verify that the insert was seated perfectly level during installation; if necessary, carefully re-apply sealant to ensure a watertight bond.

Setup, Compatibility & Care
The Twusch is designed exclusively for the Thetford C500 series. Installation involves cleaning the existing plastic surface thoroughly, applying a high-quality sanitary silicone sealant, and pressing the insert into place. Once installed, it is critical to allow the silicone to fully cure according to the manufacturer's instructions before using the toilet. For daily care, avoid using harsh abrasive scouring pads that might dull the nano-seal over time; instead, use a soft cloth and a gentle, non-abrasive cleaner to maintain the shine and hygienic properties of the ceramic surface.
