Using this toilet is easy. Just sit on the soft-close seat and use it as you would with any regular toilet. When you're done, press the flush button. As for installation, make sure to choose the right trap (S or P) according to your needs and follow the general plumbing installation steps. For maintenance, clean the Nano Glaze surface regularly with a mild cleaner to keep it looking shiny. Avoid using harsh chemicals as they might damage the ceramic. When it comes to the seat, if it needs to be removed for cleaning, use the quick-release system. And remember, you'll need to buy the Geberit in-wall cistern separately if you want to complete the setup.
