Designed by Nicholas Paterson, Kohler offers the opportunity to save water and reduce sewage and maintenance costs while also providing outstanding performance and stylish design to users. Once the liquid waste has passed through, the less dense sealing liquid maintains its position at the top of the trapway, thus providing an impermeable barrier that blocks odors. Quote from the website : “The geometry of the urinal not only provides a fresh, architectural design, but also virtually eliminates splashing. Additionally, the touch-free operation improves hygiene for all users and is more vandal-resistant due to the absence of a flush valve”. I think these are going to be used in all bathroom somewhere near in the future.
