Kohler , the C3-100, is another Kohler new product for 2006. The C3 toilet seats use water “as a refreshing, hygienic alternative to toilet tissue, offer cleanliness, comfort and convenience for all users.” The seat extends two different water nozzles for “the anterior and posterior that spray the user with warm aerated water”. The bowl is lighted so no need to turn on a light at night. The seat itself is heated, and it won’t activate unless someone’s sitting on it. The bidet functionality and the temperature are controlled from side arm unit. When not is use, the C3 seat goes into save mode to use less energy. More details at .
