With sleek, contemporary curves and a low-profile silhouette, KOHLER San Souci makes a bold statement in any bathroom. The one-piece round-front design features a compact tank that flows seamlessly into the bowl, saving space while enhancing modern decor. Its efficient 1.28-gallon AquaPiston flush delivers powerful performance while saving up to 16,500 gallons of water per year compared to older 3.5-gallon toilets. The included Quiet-Close seat prevents slamming and makes cleaning and installation effortless.
