With sleek curves and a low-profile silhouette, the KOHLER® San Souci one-piece toilet makes a strong design statement. A compact tank curves seamlessly into a round-front bowl for a space-saving profile. A 1.28-gallon flush provides significant water savings of up to 16,500 gallons per year, compared to a 3.5-gallon one-piece round-front toilet, without sacrificing performance. This toilet comes with a soft-close seat featuring innovative technology that prevents the seat from slamming and simplifies both cleaning and installation.
