Frequently asked questions
-
Twusch is easy to clean thanks to its smooth porcelain surface. For the best results, clean the bowl regularly with Thetford Toilet Bowl Cleaner. It helps remove hard water and soil deposits and is safe to use on porcelain, ceramic, plastic, and rubber seals.
You can also use Aqua Rinse Concentrated or Aqua Rinse Spray to support a smoother flush and leave a fresh, pleasant scent.
To keep the surface in top condition, avoid abrasive sponges and harsh cleaning products, as these can damage the finish over time.
-
Twusch adds a maximum of 800 g, so it is a lightweight upgrade. That is one of the reasons many people choose Twusch over a full ceramic toilet, which is typically much heavier and can have more impact on your vehicle’s overall weight.
-
Yes, you can still use your usual toilet additives with Twusch. The porcelain inlay is fully compatible with standard cassette toilet fluids, Thetford Toilet Bowl Cleaner, Aqua Rinse Concentrated, and Aqua Rinse Spray. Just stick to the product instructions for both the toilet care products and Twusch, and avoid harsh abrasive cleaners so the surface stays smooth and easy to clean. Using gentle, recommended products helps keep everything working well and looking fresh.
-
A porcelain inlay in a cassette toilet makes everyday use and cleaning a lot easier. Over time, plastic can discolour or become harder to keep looking fresh, while porcelain stays smooth, hygienic, and keeps its original colour for longer.
Because porcelain is harder and more scratch resistant than plastic, waste and residue are less likely to stick, so cleaning takes less effort and the toilet stays looking better for longer.
Porcelain can also help improve flushing efficiency, which may reduce water use and support a more hygienic toilet experience with less fuss.
-
Twusch is easy to install, within minutes. For a leak-free installation, use a premium sanitary silicone suitable for bathroom applications.
