The Kohler Corbelle toilet includes CleanCoat technology and Revolution 360 swirl flush. The swirling motion of the flush platform completely rinses the entire bowl surface, keeping it cleaner longer. This technology increases the effectiveness and power of each flush by ensuring water flows out of the tank at 360 degrees. The interior of the toilet bowl includes a CleanCoat surface technology to prevent bacteria, mildew, and hard water mineral deposit from forming. The two-piece toilet’s skirted trapway allows for a seamless, effortless clean, helping to encourage a healthy environment. 800-456-4537; www.us.kohler.com.
