Duravit 21950100U4 No.1 one-piece rimless bathroom toilet is a complete package including a soft-closing seat. The soft-closing seats are easily removable and feature stainless steel hinges. The rimless design provides exposed toilet bowl making it easier to clean and more hygienic. As mentioned in the short specifications above, this toilet has single flush mechanism. The main picture shows the right side toilet lever, but you have the option for left side lever as well. No.1 only comes in white color.

Duravit No.1 bathroom toilet has a siphonic mechanism and a standard 12″ rough-in. It uses 4.8L of water per flush as stated. Also, No.1 surface is coated with WonderGliss coating which stays smooth, attractive-looking and clean for a long time to come. Dirt and lime scale cannot secure a hold on the smooth surface, so residue runs off more easily with the water. Toilets, washbasins, bidets and urinals in all of our series are available with WonderGliss.
