The San Souci one-piece toilet offers a sleek, contemporary design combined with Kohler® touchless flush. Just hold your hand over the tank sensor to activate the flush. No handle to touch means fewer germs to pick up or leave behind. This toilet features innovative AquaPiston™ technology, a patented flush engine that delivers a fast, powerful and virtually plug-free flush. A 1.28 gal flush provides significant water savings of up to 16,500 gal per year, compared to a 3.5 gal toilet, without sacrificing performance.
